R Response? All unconscious casualties must be handled gently and every effort made to avoid any twisting or forward movement of the head and spine. S Abnormal Breathing Breathing Normally Recovery Position, Call ☎, monitor (An unconscious, breathing woman in advanced pregnancy should be placed on her left side). The recovery position: • Maintains a clear airway - allows the tongue to fall forward. • Facilitates drainage and lessens the risk of inhaling foreign material. • Permits good observation and access to the airway. • Avoids pressure on the chest which facilitates breathing. • Provides a stable position and minimises injury to casuality.

Step 2 •Stabilise the casualty by flexing the bent knee to 90° when resting on the ground. •Tuck the casualty’s hand under their armpit. •Ensure the casualty’s head is resting on their outstretched arm. CPR 30:2 Step 3 •Carefully tilt the head slightly backwards and downwards. This facilitates drainage of saliva and/or stomach contents and reduces the risk of inhalation which may cause pneumonia. 2 x Rescue Breaths D Defibrillation use AED No Shock Advised Shock Advised •Switch on •Attach pads •Follow voice prompts AED Analyses Rhythm In an EMERGENCY CALL ☎ or 4 | Essential First Aid Essential First Aid | 5 CPR HAZARDS!

Are you all right? “Open your eyes” “Squeeze my hands” SQUEEZE SHOULDERS firmly – Don’t shake NB. When approaching a collapsed casualty with caution, ascertain a response from a standing position by tapping casualty’s foot with your foot before kneeling down. • Check - for foreign material which could be obstructing the airway. • Open - use chin lift and backward head tilt to open airway. Chin lift Head tilt •Use pistol grip to achieve chin To clear foreign material lift. Watch that your knuckle doesn’t compress neck and obstruct airway and breathing. •If foreign material is present, roll casualty into recovery position and clear using postural drainage and finger sweep method. Spinal injury and infants(<1yr): Keep head in a neutral position (i.e. minimise backward head tilt) • The airway takes precedence over any other injury including a possible spinal injury (Pg 21). • Check airway and breathing in recovery position if incident involves drowning (Pg 7) or vomiting. • Look - for rise and fall of lower chest/ upper abdomen Breathing • Listen - for breath sounds • Feel - for movement of chest and escape of air from mouth Abnormal or NO Breathing? Take 10 seconds to check for breathing • If casualty is unresponsive and not breathing normally after the airway has been cleared and opened, the rescuer must immediately commence chest compressions then rescue breathing (CPR). • If unwilling or unable to perform rescue breathing, continue with compression only CPR. NB. In the first few minutes of a casualty’s cardiac arrest, sounds of gurgling, sighing or coughing may be present, but this is ineffective breathing and CPR should be commenced. Compressions 30 Compressions CPR 30 Chest Compressions : 2 Rescue Breaths = CPR • Depth = 1/3 of chest wall (At least 5 cm for adults) • Rate = 100 per min (almost 2 compressions per sec) • Place heel of one hand in centre of casualty’s chest (which is the lower half of the sternum). • Place other hand on top, arms straight and press down on sternum at least 5 cm in adults. • Allow complete recoil of chest after each compression. • Keep compressions rhythmical at a rate of 100 per min. • Use 1 or 2 hands in children (Infants 2 fingers) 2 Rescue Breaths • 2 breaths over 2 secs •Take a breath. •Close casualty’s nostrils (pinch with fingers). •Mouth to mouth (good seal). •Blow to inflate lungs. CPR 30:2 •Turn your head after each RB. •Listen and feel for air exhaled from mouth. •Avoid inhaling re-expired air. •Inflate until chest starts to rise. •Over-inflation forces air into the stomach causing regurgitation. •Infants – perform mouth to mouth/nose RB and inflate with puff of air from cheeks. •Use resuscitation mask or barrier protection if possible. •If unwilling or unable to give RB, do chest compressions only. • Cardio Pulmonary Resuscitation • Rate = 5 cycles every 2 mins • Combines 30 Compressions with 2 Rescue Breaths (30:2) = 1 cycle Same ratio for infant, child, adult • Change rescuers every 2 mins to reduce fatigue. Stop CPR when: • Do compression only CPR, if unwilling or unable • Casualty responds or begins breathing normally • Exhaustion – can’t continue. to give rescue breaths (RB). • Health professional arrives and takes over. • Continue CPR until responsiveness or normal • Health professional directs that CPR be ceased. breathing returns. Defibrillation An AED (Automated External Defibrillator) delivers electric shock to reverse abnormal heart rhythms. Not all heart rhythms are reversible. • When there are 2 rescuers, continue CPR while one rescuer organises and attaches AED pads (Pg 41): • Expose chest – cut clothing. • Remove any medication patch, remove jewelry, wipe chest dry, remove chest hair with razor. • Switch on AED & attach pads – peel backing off first. • Follow voice/ visual prompts of the AED. • Nobody should touch casualty during analysis or shock delivery • DO NOT have casualty in contact with metal NB.No harm to rescuers has occurred while using an AED in the wet Chain of survival (Pg 42): is the key to improving the survival rate from cardiac arrest. Time Early 2) Begin CPR immediately is the essence. The 4 steps required are: 1) Call 3) Early Defibrillation 4) Advanced cardiac life support by paramedics. ☎ 6 | Essential First Aid Choking Essential First Aid | 7 Inhalation of a foreign body can cause partial or complete airway obstruction. Partial Airway Obstruction (Effective cough): FIRST AID SIGNS & SYMPTOMS • Encourage casualty to keep coughing • Reassure • DO NOT deliver back-blows if cough is effective. If blockage doesn’t • Call clear • Coughing • Wheezing • Difficulty breathing • Noisy breathing • Cyanosis (blue skin colour) ☎ Complete Airway Obstruction (Ineffective cough): SIGNS & SYMPTOMS • Unable to breathe, speak or cough • Agitated/ distressed • Grips the throat • Cyanosis (blue) • Rapid loss of consciousness standing or lying using the heel of the hand between the shoulder blades. If after 5 back blows the airway is still obstructed, use chest thrusts. Back Blows Back blows are delivered with the infant lying face down across the lap. Check airway after each back blow. Drowning or near drowning is the process of experiencing respiratory impairment from immersion in liquid. Interruption of the oxygen supply to the brain is the most important consequence of drowning so early rescue and resuscitation are the major factors in survival. SIGNS & SYMPTOMS • Coughing • Chest pain • Frothy sputum • Clenched teeth • Shortness of breath • Blue lips and tongue • Unconscious • Irregular or no breathing A Drowning Victim FIRST AID • Deliver up to 5 back-blows. • Check and clear mouth after each blow. • Deliver up to 5 chest thrusts. • Check and clear mouth after each blow. • Repeat back blows and chest thrusts if obstruction not relieved. . • Call • If unconscious, commence CPR (Pg 4,5). DO NOT apply abdominal pressure – may cause internal injury. Chest Thrusts When giving Rescue Breaths in an attempt to blow past the obstruction, there will be resistance. If the obstruction is blown further down the airways, the obstruction can be removed later by bronchoscope. • DO NOT attempt to save a drowning casualty beyond your swimming ability. • Remove casualty from water as soon as possible. • Only begin Rescue Breathing in water if trained to do so (requires a floatation aid) and immediate exit is impossible. • Cardiac compressions in water are both difficult and hazardous and should not be attempted. FIRST AID On land or boat: • Call • Roll casualty into recovery position for assessment of airway and breathing. • Commence CPR if required (Pg 4,5) • Roll into recovery position if vomiting or regurgitation occurs. • DO NOT attempt to empty distended stomach by external compression. • Treat for hypothermia (Pg 29) - often associated with immersion. • Give oxygen if trained (Pg 36). • All immersion casualties must be assessed in hospital as complications often follow. ☎ ☎ Chest thrusts are delivered standing, sitting or lying using one or two hands - a wall or firm surface is required. The elbow(s) are slightly bent and chest thrusts are sharper and slower than chest compressions (CPR). Check airway after each chest thrust. Back blows are delivered Drowning The risk of regurgitation and inhalation is high following immersion. This is due to distension of the stomach from swallowing large volumes of water. The airway and breathing is assessed in the recovery position to minimise risk of inhalation. Rescuing a Drowning Victim • If conscious: Throw a buoyant aid (life jacket, surf board) or drag from water using an umbrella, rope, towel, stick. • If unconscious: Turn casualty face up and remove from water. • Consider possibility of spinal injury (Pg 21) – remove from water gently, maintaining spinal alignment as much as possible. 8 |Trauma Trauma | 9 Soft Tissue Injury & Fracture Sprain:Over-extension of a joint with stretching and tearing of ligaments. Strain: Over-stretching of muscles and tendons with tearing of muscle tissue or tendon fibres. Slings: Use a triangular bandage or improvise. Soft Tissue Injury Improvise: By using a belt or buttons on shirt Dislocation: Displacement of bone ends in a joint. Fracture: Broken bones can be classified as: Closed: Fractured bone doesn’t penetrate skin. Open: Fracture is exposed through open wound or penetrates skin. Complicated: Vital organ, major nerve or blood vessel is damaged by a broken bone. The Signs & Symptoms and First Aid for a fracture and soft tissue injury are very similar. FIRST AID SIGNS & SYMPTOMS • Pain • Tenderness • Snap or pop at time of injury • Restricted movement • Discolouration • Swelling • Deformity* * Indicative of fracture or dislocation Fracture Management: • Control external bleeding or cover wound (Pg 12) • Remove rings from fingers – swelling likely • Support or Immobilise +/_ R.I.C.E • Medical Assistance: X-rays are the only sure way of diagnosing the type of injury. if: Deformity as blood vessels • Call and nerves can be damaged. Open Fracture: Risk of blood loss and infection. Breathing difficulty • Monitor Vital Signs (Pg 81) The radius always attaches to the thumb. ☎ The main aim of fracture treatment is to support or immobilise an injured part which: • Minimises pain • Prevents further damage • Minimises bleeding and • Prevents a closed fracture becoming an open fracture. Support: • Leave injured part as found and pack around to give support. Immobilise: Elevation Sling Arm Sling for 10 - 20mins – do not place ice directly on skin. Ice pack or frozen peas can be placed over a bandage. Continue to cool injury three times/day for 2-3 days after the injury. Compression: Apply a firm supporting bandage to injured part. This restricts movement of injured part and reduces bleeding and swelling. Elevation: Raise injured area above the level of the heart if possible. This slows the flow of blood and reduces swelling. Note: • Degree of pain is not a good indicator of injury type since pain tolerance varies in individuals (Pg 56). • Never manipulate a dislocation - there may be an associated fracture. • When in doubt, always treat an injury as a fracture. • Check circulation (Pg11) after immobilisation ie after bandaging, splinting, sling. • You may need to slowly adjust position of limb if no circulation is present. Rigid Splint: Rolled up newspaper, tied either end with triangular bandages. Fractured humerus: Notice deformity • Use Splint, Sling or bandage to prevent movement. • Stabilise joint above and below fracture site. • Apply triangular or broad bandages above and below fracture site. • Check circulation every 15mins (Pg 11). • DO NOT elevate a suspected fracture until it has been immobilised. Soft Tissue Management: R.I.C.E: Method used to treat soft tissue injuries (sprains/ strains) and fractures. Rest: Rest casualty and injured part; this prevents further damage and reduces bleeding. Ice: Reduces pain, fluid and swelling by constricting blood vessels. Apply wrapped ice pack Upper Limb Injury Finger Splints: Immobilisation reduces pain. After splinting, apply an elevation sling to minimise swelling. Pain in: Shoulder Collar & Cuff Sling Could be: •Fractured clavicle •Dislocated shoulder •Fractured upper humerus •Sprain/ strain Upper Arm •Fractured mid-humerus •Sprain/ strain Fore Arm/ Wrist •Fractured radius/ ulna •Sprain/ strain •Fractured carpal bone Hand •Fractured/ dislocated metacarpal •Fractured/ dislocated phalange •Sprain/ strain Management: •Allow casualty to adopt position of comfort. •Apply sling which best suits casualty. •Keep hand higher than elbow to reduce swelling •If unsure whether injury is a fracture or soft tissue injury, treat as for fracture (Pg 8) 10 |Trauma Trauma | 11 Lower Limb Injury Pelvic Injury: SIGNS & SYMPTOMS • Pain in hip or groin region • Pain worse on movement • Inability to walk • Shock (Pg 14) Immobilising Lower limb: FIRST AID ☎ • Call • Reassure casualty • Control any external bleeding. • Lie casualty flat with knees slightly bent and supported. • Place padding between legs and on either side of hips (eg blanket, towel, pillow). • ‘Figure-of-eight’ bandage around ankles and feet. • Apply broad bandage above knees. • Don’t attempt to move casualty. • Discourage attempts to urinate. • Maintain body temperature. • Monitor vital signs (Pg 81) Consider internal bleeding from bladder, uterus, bowel damage. Hip Injury Left leg appears shorter and is rotated outwards. Notice swelling over hip due to internal bleeding. This is the typical position of the leg with a fractured hip (fractured neck of femur) and is common in the elderly after a minor fall. A 1.5 litre blood loss can result from a closed fracture of the femur. In this case a 3 litre blood loss could result in shock (Pg 14) and death. This type of injury is common in road traffic accidents. Thigh Injury R.I.C.E (Pg 8) R.I.C.E (Pg 8) Ankle Injury for a sprained ankle: Rest: Casualty doesn’t move ankle Ice: Cool injured area Compression: Use a crepe bandage Elevation: Place foot higher than hip for a sprained knee: Support knee in position of comfort. Do not try to straighten knee if painful. Knee Injury Lower Limb Injury • A body splint is an effective way Fracture site to immobilise lower limb fractures. • The key to immobilising leg fractures is a figure of 8 bandage around the feet.

Lower limbs, fingers and toes are commonly strapped together as body splints. further than length of legs. • Soft Splint: Folded blankets, towels, pillows. • Ensure splint stabilises joints • Rigid Splint: Boards, sticks, metal strips, folded above and below injury. magazines and newspapers. • Pad over splint to make more comfortable. Checking Circulation: • Check circulation • Check skin colour below injury - if pale or discoloured, there may be impaired circulation. • Assess skin temperature by gently placing hand below SIGNS AND SYMPTOMS that level of injury. Compare to other side. If colder, there a bandage is too tight: may be impaired circulation. • Pain • Numbness • Cold • Squeeze fingernail until nail turns white. Colour should to touch • Tingling • Pale or return within a few seconds. discoloured • Pulse weak/absent • Compare pulse below injury with other side - if weaker below injury. or absent, circulation may be impaired.

Bleeding is classified according to the type of blood vessel damaged: Artery - bright red, spurting; Vein - dark red, flowing; Capillary - bright red, oozing. Types of wounds associated with bleeding are: (See also Pg 62) • Abrasions • Incisions • Laceration • Puncture • Embedded object • Tear • Amputation. Major External Bleeding: The aim is to reduce blood loss from the casualty. Direct Pressure and Elevation FIRST AID • Check for dangers to self, casualty & bystanders. • Use disposable gloves if available. • Direct Pressure Method: • Quickly check for embedded objects (Pg13) • Apply firm direct pressure until bleeding stops. • Maintain pressure over the wound using hands or pad (sterile dressing, tea towel or handkerchief). • Bandage firmly to hold pressure pad in place. • If bleeding continues - apply another pad and a tighter bandage. • Elevate, immobilise and rest injury. • Call • Reassure casualty. • Assist casualty into position of comfort. • Monitor vital signs (Pg 81). • Give oxygen if trained (Pg 36). • DO NOT give casualty food, alcohol, medication. • If major bleeding continues - remove all pads to locate a bleeding point, then apply a more direct pressure over bleeding point. • If above methods fail - use a tourniquet. • Treat for shock (Pg 14) if required. Direct, sustained pressure is the fastest, easiest, most effective way to stop bleeding. TOURNIQUET: Used to control life-threating bleeding. • Use as a LAST RESORT. • Use a wide bandage (>5cm wide). • Apply high above wound. • Ensure tourniquet is clearly visible. • Tighten until bleeding stops. • Note the time of application; write time of application on casualty. • Continue to maintain direct pressure over wound. • DO NOT apply tourniquet over a joint or wound. • DO NOT remove tourniquet until casualty receives specialist care. ☎ Embedded Object: eg knife, glass, stick or metal. FIRST AID • DO NOT remove the object - it could be plugging the wound. • Build up padding around the object. • Apply sustained pressure over the pad (indirect pressure). • Bandage firmly over the pad. • DO NOT apply pressure over the object. • DO NOT shorten object unless its size is unmanageable. • Elevate, immobilise, restrict movment of the limb. • Advise casualty to remain at rest. • Call ☎ Internal Bleeding: Signs, symptoms and management as for Shock (Pg 14) • Suspect internal bleeding if a large blunt force is involved - eg road traffic accident, fall from a height; or a history of stomach ulcers, early pregnancy (ectopic pregnancy) or penetrating injury. • Internal bleeding may be concealed or revealed. • If a casualty is coughing up frothy blood, allow casualty to adopt position of comfort – normally half-sitting. • First aiders can’t control internal bleeding but can save lives. early recognition and calling ☎ Concealed: (no bleeding visible) • Spleen • Liver • Pancreas • Brain Revealed: • Lungs – Cough up frothy pink sputum. • Stomach – Vomit brown coffee grounds or red blood. • Kidneys/ Bladder – Blood stained urine. • Bowels – Rectal bleeding: bright red or black and “tarry”. • Uterus - Vaginal bleeding. Nose bleed FIRST AID • Pinch soft part of nose just below the bone. • Have casualty seated and leaning forward. • Ask casualty to breathe through their mouth. • Maintain pressure and posture for at least 10mins (longer may be required after exercise, hot weather or if casualty has high blood pressure or takes aspirin or warfarin tablets - maintain pressure for at least 20 minutes). • If bleeding continues >20mins - seek medical assistance. • Apply cold compress to forehead and neck. • Advise casualty not to blow or pick their nose for a few hours. Amputation Tourniquet with time of application noted Bleeding Manage amputated limb as for major external bleeding (Pg 12). Amputation of a limb often requires a tourniquet (Pg12) to control life-threatening bleeding. • DO NOT wash or soak amputated part in water or any other liquid. • Wrap the part in gauze or a clean handkerchief and place in watertight plastic bag. • Place sealed bag or container in cold water which has ice added to it. • The amputated part should not be in direct contact with ice. • Send to hospital with the casualty. 14 |Trauma Trauma | 15 Shock Shock is a term used to describe an ineffective blood circulation. CAUSES: Loss of blood volume: Bleeding or fluid loss Loss of blood pressure: Heart/ pump failure or abnormal blood vessel dilatation. • Internal or external bleeding bleeding • Major or multiple fractures • Severe burns or scalds • Severe diarrhoea and vomiting fluid loss • Heat stroke The total blood volume in the body is • Heart attack - pump failure about 6 litres. Blood loss of >1 litre • Severe infection (20%) may result in shock. Rapid abnormal • Allergic reactions blood loss leads to more severe dilatation of • Brain/ spinal cord injury blood vessels shock. SIGNS & SYMPTOMS • Pale, cool, clammy skin • Thirst • Feeling cold • Feeling Faint • Rapid, shallow breathing. • Nausea/ vomiting • Confusion • Reduced level of consciousness. • Rapid, weak pulse • Ridged, painful abdomen (from internal abdominal bleeding). NOTE: In early stages of blood loss, children may have a normal pulse rate, but pallor is the warning sign. FIRST AID • DRSABCD - Ensure your own safety • Call • If conscious – lie casualty flat • Control external bleeding (Pg12); stabilise fractures; treat injuries (use disposable gloves if available). • Give oxygen if trained (Pg 36) • Give nothing by mouth (may cause vomiting and delay surgery). • Keep casualty warm but don’t overheat. • Reassure while monitoring vital signs (Pg 81). • If casualty becomes unconscious, vomits or has breathing difficulty, place in recovery position and monitor. ☎ Crush Injury A heavy, crushing force to part of the body usually causing extensive tissue damage from internal bleeding, fractures, ruptured organs, or an impaired blood supply. FIRST AID • DRSABCD - Ensure your own safety. • Call • If safe - remove crushing force as soon as possible. • Control external bleeding (Pg12). • DO NOT use a tourniquet (Pg12) to manage a crush injury. • Manage other injuries. • Give oxygen if trained (Pg 36). • Reassure while monitoring vital signs (Pg 81) NB - the casualty’s condition may deteriorate quickly due to extensive damage. ☎ Crush Injury Syndrome: •Is a complication of crush injury usually involving a thigh or pelvis (ie not a hand or foot). •Toxins released from damaged tissue may cause complications but the risk of sudden death following removal of a crushing force is extremely small. Burns Burns may result from: • Heat (flame, scald, direct contact) • Cold • Friction • Chemical (acid, alkali) • Electrical • Radiation (sunburn, welders arc). • DO NOT apply ice directly to burns.

SIGNS & SYMPTOMS Dry towel around casualty’s ankles to move from electrical source. DO NOT touch casualty’s skin before electrical source is disconnected. BEWARE: Water on floor and metal materials can conduct electricity from casualty to you. • When POWERLINES are in contact with a vehicle or a person, there should be no attempt at removal or resuscitation of the casualty until the situation is declared safe by electrical authorities. • Remain at least 6m from energized material (car body, pool of water, cable). • You can do nothing for a casualty within the danger zone! Protect yourself and others. Triage/ Prioritizing You may be faced with the dilemma of two or more casualties needing your care. In making a decision who to treat first, remember the goal is for the greatest good for the greatest number of people. In all cases remember the principles of safety to yourself, bystanders and casualty. Prioritize casualties as follows: Code Red URGENT - Immediate resuscitation and stabilization eg • Control severe bleeding • Open & stabilize airway in an unconscious casualty. Priority 2 HIGH - Treatment but no active resuscitation eg • Burns • Spinal injury • Open fracture • Crush injury • Head, Chest , Abdominal Injury. Priority 3 LOW - Walking Wounded eg • Cuts • Grazes • Sprains • Closed fracture. Priority 4 NO ACTION - Dead or beyond help eg • Decapitation • Massive head or torso injuries. Code yellow Code Green Code Black Major chest injuries include fractured rib, flail chest (multiple rib fractures, producing a floating segment of ribs), and sucking chest wound. A fractured rib or penetrating injury may puncture the lung. Fractured Rib/ Flail Chest: ☎ Priority 1 Chest Note: A casualty is always in a changing, non static condition. This is especially important in head (Pg 20) and abdominal injuries (Pg 18) in which deterioration can occur - monitor vital signs (Pg 81). •Holding chest •Pain at site •Pain when breathing •Rapid, shallow breathing •Bruising •Tenderness •Blue lips (flail chest or punctured lung) •Flail Chest –section of chest wall moves in opposite direction during breathing. •Onset of shock (Pg 14) FIRST AID •Position casualty in position of comfort - half-sitting, leaning toward injured side, if other injuries permit. •Encourage casualty to breathe with short breaths. •Place padding over injured area. •Bandage the upper arm on injured side to the body. •If bandages increase discomfort, loosen or remove them. •Apply a ’Collar & Cuff’ sling to arm on injured side (Pg 9). •Call •Monitor for internal bleeding/ shock (Pg 13, 14) •Give oxygen if available (Pg 36). •If Unconscious: Recovery position, injured side down. ☎ Sucking Chest Wound: SIGNS & SYMPTOMS • Pain • Breathing difficulty • Sucking sound over wound when casualty breathes. • Bloodstained bubbles around wound when casualty breathes. • Coughing up bloodstained frothy sputum. • Onset of shock (Pg 14). FIRST AID • Assist casualty into position of comfort - half-sitting, leaning toward injured side. • If the object is still in place, stabilise with padding around the wound. • If the wound is open, cover with plastic or non-stick pad taped on 3 sides -this allows air to escape from pleural cavity and prevents lung collapse (pneumothorax). • Call • Monitor for internal bleeding/ shock (Pg 13, 14). • Administer oxygen if available (Pg 35). ☎ 18 |Trauma Abdomen An injury to the abdomen can be an open or closed wound. Even with a closed wound the rupture of an organ can cause serious internal bleeding (Pgs 13, 14), which results in shock (Pg 14). With an open injury, abdominal organs sometimes protrude through the wound. FIRST AID ☎ • Call • Place casualty on their back with pillow under head and shoulders and support under bent knees. • If unconscious - place in recovery position. • Cover exposed bowel with moist non-stick dressing, plastic cling wrap or aluminium foil. • Secure with surgical tape or bandage (not Open Abdominal Injury tightly). Plastic cling wrap has been placed over an • Rest and reassure. open abdominal wound and secured with surgical tape. • Monitor vital signs (Pg 81). • Administer oxygen if available (Pg 36). • Elevate legs if shock develops (Pg 14). • DO NOT push bowel back into abdominal cavity. • DO NOT apply direct pressure to the wound. • DO NOT touch bowel with your fingers (may cause spasm). • DO NOT give food or drink (this may delay surgery for wound repair). Trauma | 19 Eye Types of eye injuries: • Burns • Foreign bodies • Penetrating injury • Direct blow Burns: FIRST AID Chemical - acids, caustic soda, lime UV - Welder’s flash, snow blindness (the eyes are red and feel gritty hours later) Heat - flames or radiant heat Contact Lenses: • DO NOT remove if the surface of eye is badly damaged • Casualty should remove own lenses • Lenses may initially protect the eye but if a chemical or foreign body tracks under the lens, severe injury may occur. • IRRIGATE with cool running water or sterile eye (saline) solution for 20 -30mins. • Flush from the inside to the outside of eye. • Irrigate under the eyelids. • Lightly pad affected eye(s). • Seek urgent medical assistance. • Chemical burn - DO NOT waste time looking for neutralizing agent - irrigate as above with water or saline solution. • NB. Alkaline burn is worse than acid burn. Foreign body: Grit, dust, metal particles, insects, eyelashes. FIRST AID • Gently irrigate eye to wash out object – use sterile eye (saline) solution or gentle water pressure from hose/ tap. • If this fails, and the particle is on white of eye or eyelid, gently lift particle off using a moistened cotton bud or the corner of a clean handkerchief. (DO NOT attempt this if particle is on coloured part of eye – irrigate only) • If still unsuccessful, cover the eye with a clean pad ensuring no pressure is placed over injured eye. • Seek medical aid. • DO NOT allow casualty to rub eye. Penetrating Injury: FIRST AID • Lay the casualty flat. • Reassure • Call • Place padding around the object. • Place a paper cup over the object to stabilize it. • Tape or bandage to hold in place. • Advise casualty to avoid moving unaffected eye, because this will cause movement of injured eye. • Cover the unaffected eye, but remove if casualty becomes anxious. • DO NOT remove embedded object. • DO NOT apply pressure over the object. ☎ Direct Blow: Any direct blow to the eye such as a fist or squash ball can cause fracture of the eye socket or retinal detachment. FIRST AID • Rest and Reassure • Place padding over eye • Secure with tape or bandage • Ask casualty to limit eye movement • Seek urgent medical aid 20 |Trauma Trauma | 21 Head Injury Spinal Injury Blood or fluid from the ear may indicate a ruptured eardrum (Pg 53) or skull fracture: • Position casualty injured side down to allow free drainage of fluid from the ear. • DO NOT plug or bandage ear. SIGNS & SYMPTOMS •Headache or giddiness •Nausea or vomiting •Drowsy or irritable •Slurred speech •Blurred vision •Confused or disorientated. •Loss of memory •Swelling and bruising around eyes. •Bleeding into corner of eyes. •Bruising behind ears. •Straw coloured fluid or bleeding from nose or ear. •Loss of power in limbs. •Loss of co-ordination. •Seizure •Unequal pupils •Loses consciousness, even briefly. Concussion: “Brain Shake” is a temporary loss or altered state of consciousness followed by complete recovery. Subsequent decline (see signs and symptoms above) suggests a more serious brain injury. Conscious: Cervical SIGNS & SYMPTOMS Lumbar Thoracic Spinal Column •AIRWAY management takes priority over any other injuries. •ALL cases of unconsciousness, even if casualty was unconscious only briefly, must be assessed by a doctor. •If casualty didn’t lose consciousness, but later develops any of the following signs and symptoms (below), urgent medical advice must be sought. •Monitor all casualties closely for the first 8 hrs after a head injury. •All head injuries should be treated as a suspected spinal injury until proven otherwise. (See also Pgs 48, 49) The key to managing a spinal cord injury: Protect airway & Minimise spinal movement. FIRST AID Check DRSABCD (Pg 3) Conscious: • Support casualty’s head as best as possible. • Reassurance, especially if confused. • If blood or fluid coming from ear or nostril, loosely cover with a dressing (do not plug). • Control bleeding and cover wounds (Pg 12). • DO NOT give anything to eat or drink. • DO NOT give analgaesia (Pg 56) for headache may cause drowsiness and confuse vital signs. • Prepare for possible vomit – locate bowl, towel. • Administer oxygen if available (Pg 36). • Seek urgent medical aid. Unconscious: • Recovery position with head & neck support. • Call • Continuously monitor & record vital Signs every 5-10mins (Pg 81). • Control bleeding and cover wounds. • Support/stabilize head and neck. • Keep warm with a blanket. • Prepare for possible vomit. ☎ Cerebral Compression: Brain swelling or bleeding within the skull shows deteriorating signs and symptoms (above). This is a serious brain injury and could be life threatening. • Pain in neck or back. • Pins and needles in any part of body. • Numbness or weakness. • Unable to move legs or arms. • Uncontrolled penile erection. • Onset of shock (Pg 14). FIRST AID • Prevent further injury by AVOIDING movement of patient - leave this to the experts. • Advise casualty to remain still. • Call • Support the head and neck. • Reassure casualty. • Maintain body temperature with a blanket. ☎ QUICK CHECK Conscious Casualty: Support the head and neck in a conscious casualty with neck pain. Do not remove helmet and ask casualty to remain still. Suspect spinal injury with: Unconscious casualty: (Log Roll Technique) Turn casualty onto their side, maintaining head, neck, and spinal alignment. Rescuer at head takes charge. Maintain an open airway. • Can you wriggle your fingers and toes for me? • Can you make a fist? • Can you shrug your shoulders? • Can you pull your toes up towards you and point them away? • Do you have pins and needles anywhere? • Can you feel me touch your hands/ feet? NB. If the casualty has neck or back pain- treat as a spinal injury. The pain may be due to an unstable vertebral fracture which may result in spinal cord damage if handled incorrectly. Motor vehicle accidents, motor bike and cyclists, diving, falls from a height, minor falls in the elderly and sports injuries such as rugby and horse riding. Unconscious: Any person found unconscious is potentially spinal injured until proven otherwise - turn casualty onto their side and maintain an open airway. REMEMBER, airway management takes priority over spinal injury. Helmet Removal: Helmets could be preventing further spinal or head injuries. If a full-face (motorcycle) helmet is impeding proper airway management in an unconscious casualty and/ or you need to perform CPR, the helmet needs to be removed carefully (Pg 50). Otherwise leave helmet removal to the experts. FIRST AID • Recovery position with head & neck support. • Call • Continuously monitor & record vital Signs every 5-10mins (Pg 81). • Control bleeding and cover wounds. • Support/ stabilize head and neck. • Keep warm with a blanket. • Prepare for possible vomit. ☎ 22 | Medical Emergencies Heart Conditions Medical Emergencies | 23 Angina is a “cramping” of the heart muscle; relieved by rest, with no permanent muscle damage. Heart attack is caused by a blocked coronary artery, resulting in muscle damage which may lead to complications such as cardiac arrest. Cardiac arrest (Pg 42) is a condition in which the heart stops beating and pumping effectively. The damage caused by a heart attack may cause abnormal rhythms (Venticular Fibrillation) which result in cardiac arrest (Pg 40). Some abnormal rhythms can be reversed by an AED. Cardiac arrest is fatal without basic life support (Pg 3). “Heart attack” and “Angina” are heart conditions which present with similar signs and symptoms. SIGNS & SYMPTOMS – vary greatly, and not all symptoms and signs are present! • Central chest pain – may be described as •Crushing •Tightness •Heaviness • Breathlessness or difficulty “catching the breath” • Indigestion type pain in the upper abdomen (referred pain from the heart) • Pain radiating to the •Jaw •Neck •Shoulder •Left arm • Heaviness or weakness in left arm • Dizzy • Nauseous NB. Casualties having a heart attack may present with • Pale and sweaty breathlessness alone while others may have heaviness • Irregular pulse in the arm or believe they have indigestion. Asthma Asthma is spasm and narrowing of the airways with inflammation and increased mucus production which causes breathing difficulties. Asthma attacks are triggered in sensitive airways by changes in the weather, exercise, emotional stress, pollen, dust-mite, food preservatives, smoke, fumes or cold and flu infection. • Dry cough • Wheeze – during exhalation • Breathless but speaks in sentences Moderate: • Wheeze - during exhalation and inhalation • Rapid breathing • Breathless - speaks in phrases • Anxious • Pale and sweaty • Rapid pulse Severe: • Can’t speak (too breathless) • Wheeze inaudible (no air movement) • Cyanosis (blue lips) • Exhaustion • Distressed • Altered state of consciousness • Collapse - Respiratory arrest FIRST AID • STOP and REST – in position of comfort (usually sitting). • Reassure and talk to casualty – Are you on prescribed heart medication? Do you have angina? Can you take aspirin? • If casualty has no heart medication and has never been diagnosed with heart problems ’ • Give aspirin if directed • Monitor – treat as for HEART ATTACK • Call ‘ • Assist casualty to take prescribed heart medication (anginine tabs or GTN spray). • If after 5 mins symptoms are not relieved, and if directed, give another dose of heart medication. Warning signs: DON’T WAIT Pain lasts > 10 mins ACT NOW Pain gets suddenly worse Aspirin should be given if directed. DO NOT give aspirin if: • Casualty takes Warfarin (blood thinning medication) • Allergic to aspirin • History of Asthma or Stomach ulcers Call ☎ Give Aspirin 300mg (one chewable tablet) if directed. Monitor vital signs Give Oxygen if trained (Pg 36) Vital Signs (Pg 81) Prepare for CPR • Sit casualty comfortably upright. • Calm and reassure. • Follow casualty’s Asthma Action Plan or give: • Reliever Medication - 1 puff followed by 4 breaths, repeat 4 times (total 4 puffs). • If no improvement in 4 mins, repeat. • Call if no improvement • Give oxygen if trained (Pg 36). • Keep giving 4 puffs every 4 mins until ambulance arrives or casualty improves significantly. • Collapse: • Commence DRSABCD (Pg 3) ☎ Rescue breaths require much greater force due to narrowed airways. Slowly inflate with a steady pressure until chest begins to rise. Allow time for chest to fall during expiration. It may take longer to give the two rescue breaths. Give Reliever Medication via spacer. Use puffer on it’s own if spacer not available. ☎ ANGINA should be relieved by rest and medication (tablets or spray). • If after 3 doses of medication over 10mins, the pain has not diminished, then the condition should be considered a HEART ATTACK FIRST AID SIGNS & SYMPTOMS Mild: Spacer Reliever Medication: • Blue - grey coloured inhalers (puffers) eg Ventolin, Respolin, Atrovent, Salbutamol. •Borrow an inhaler if necessary. • No harm is likely to result from giving a Reliever to someone who does not have asthma. Using Puffer - no spacer • Shake inhaler (Puffer). • Place mouthpiece in casualty’s mouth. • Administer 1 puff as casualty inhales slowly and steadily. • Casualty takes 4 normal breaths. • Continue until 4 puffs have been given. • Wait 4 mins and repeat if no improvement. Using Puffer - with a spacer • Shake inhaler and place mouthpiece into spacer. • Place spacer mouthpiece into casualty’s mouth. • Administer 1 puff and ask casualty to breath in and out for 4 breaths. • Continue until 4 puffs have been given. • Wait 4 mins and repeat if no improvement. 24 | Medical Emergencies Medical Emergencies | 25 Croup/ Epiglottitis Croup and Epiglottitis are infections of the upper airways (larynx, pharynx and trachea) and occur in young children. Both conditions start with similar signs and symptoms but epiglottitis progresses to a life-threatening state. Croup: Viral infection EPIGLOTTITIS: • Drools –can’t swallow • Quiet, doesn’t cough • Leans forward • Won’t talk • High temperature • Skin flushed Mild FIRST AID Severe SIGNS & SYMPTOMS CROUP: • Cold-like symptoms • Barking cough • Noisy breathing • Slight temperature • Worse at night • Breathing difficulties • Cyanosis (blue lips) • DO NOT examine child’s throat – this may cause complete blockage. • Calm and Reassure. • Steamy shower room. • Paracetamol • Seek medical aid. ☎ • Call • Comfort, reassure • Sit upright on your lap. • Lots of TLC until ambulance arrives. affecting upper airways in infants and children < 4yrs. Slow onset, usually follows a cold or sore throat and lasts 3 – 4 days. Epiglottitis: Bacterial infection of the epiglottis (flap above the vocal cords) causing upper airway obstruction. It usually occurs in the 4 - 7yr age group and has a rapid onset over 1-2hrs. This is an emergency and requires urgent ambulance transport to the hospital. Steam helps alleviate symptoms of Croup but won’t cure the problem. Doctors find it difficult to clinically differentiate between Croup and Epiglottitis - further tests are usually required. A seizure is caused by abnormal electrical activity in the brain. Seizures vary from the briefest lapses of attention to prolonged convulsions (tonic-clonic or grand mal seizure). A seizure can occur in a person with • Epilepsy • Head Injury (Pg 20) • Stroke (Pg 27) • Meningitis • Fever (febrile convulsion) • Hypoglycaemia (diabetics Pg 26) • Poisoning (Pg 32) • Alcohol and • Drug Withdrawal (Pg 58). SIGNS & SYMPTOMS Tonic-Clonic Seizure (Grand Mal) • Aura (warning sign: eg abnormal taste, smell, sound or sight). • Cry out or make moaning sound. • Collapse and momentary rigidity (tonic phase – lasts few secs). • Eyes roll upwards or stare. • Jerking movements of body (clonic phase – lasts few mins). • Blue discolouration of face/ lips • Excessive salivation • Tongue biting may result in blood stained saliva. • Loss of bladder or bowel control. • Breathing ceases – resumes once seizure finishes. • Drowsiness and lethargy follows. Febrile Convulsion FIRST AID • Protect from harm – remove dangerous objects or protect head with cushion/ pillow. • Note the time. • AVOID restraining unless this is essential to protect from injury. • DO NOT put anything into casualty’s mouth. • Roll into Recovery position as soon as possible. • Monitor Vital Signs (Pg 81). • Reassure casualty and allow to sleep under supervision at end of seizure. •Call if: • Seizure lasts longer than 5mins. • Another seizure quickly follows. • Casualty is pregnant or has diabetes. • Seizure occurred in water. • This is casualty’s first ever seizure. • Casualty is injured or you’re in doubt. ☎ A person known to have epilepsy may not require ambulance care. (Normal body temperature = 37°C) Febrile convulsions are associated with a high body temperature (>38°C). It is the rate of rise in temperature, not how high it gets, which causes the convulsion. They occur in 3% of all children between the age of 6mths and 6yrs. Faint Fainting is a sudden, brief loss of consciousness caused by lack of blood flow to the brain with full recovery. It often occurs in: • Hot conditions with long periods of standing • Sudden postural changes (eg from sitting to standing) • Pregnancy (lower blood pressure) • Pain or emotional stress (eg sight of blood). Seizure/ Epilepsy SIGNS & SYMPTOMS • Dizzy or light headed. • Nausea • Sweating • Return of consciousness within a few seconds of lying flat. • Pale and sweaty • Mild confusion or embarrassment. FIRST AID • Lie casualty flat • Raise legs • Pregnant woman turn onto left side. • Recovery position if unconscious for more than a few seconds. • DO NOT give food or drink. • Check for other injuries. SIGNS & SYMPTOMS (Similar to epilepsy + fever) • Fever • Skin hot, flushed • Eyes roll up • Body stiffens • Back and neck arches • Protect from harm • Place in • Jerking of face, limbs recovery position after seizure • Frothing at mouth • Blue face and lips stops • Remove excess • Lethargy follows clothing FIRST AID • Manage as for Seizure/ Epilepsy (above). PLUS: • Remove excess clothing • Apply moist cloth to forehead (no ice). • DO NOT allow shivering to occur • DO NOT put in cold bath 26| Medical Emergencies Medical Emergencies | 27 Diabetes • Diabetes is an imbalance between glucose and insulin levels in the body. • The imbalance may result in Hypoglycaemia (Low blood sugar) or Hyperglycaemia (High blood sugar). Both conditions, if left untreated, result in altered states of consciousness which are medical emergencies. DIFFERENCES SIGNS & SYMPTOMS - Both conditions share similar signs and symptoms: • Appear to be drunk (Dizzy, drowsy, confused, altered level of consciousness) • Rapid breathing • Rapid pulse • Unconscious HYPOglycaemia (LOW) • Pale, cold sweaty skin • Fast progression • Hunger • Trembling • Weakness • Seizure HYPERglycaemia (HIGH) • Warm, dry skin • Slow progression • Acetone smell on breath (nail polish remover) • Thirst • Passes urine frequently • Nausea and vomiting • Abdominal Pain • The most common type of diabetic emergency is Hypoglycaemia. • Hyperglycaemia is not common, as its slow onset allows diabetics to take corrective measures.

Stroke •The blood supply to part of the brain is disrupted, resulting in damage to brain tissue. •This is caused by either a blood clot blocking an artery (cerebral thrombosis) or a ruptured artery inside the brain (cerebral haemorrhage). •The signs and symptoms of a “stroke” vary, depending on which part of the brain is damaged. SIGNS & SYMPTOMS • Confusion or dazed state • Headache • Unequal-sized pupils • Blurred vision • Drooping of one side of face • Slurred speech • Difficulty swallowing - drool • Weakness or paralysis affecting one side of body. • Loss of balance • Incontinence of bladder/ bowel. • Seizure • Unconsciousness FAST is a simple way of remembering the signs of a stroke: • Facial weakness – Can the casualty smile? Has their mouth or eye drooped? • Arm weakness – Can casualty raise both arms? • Speech – Can casualty speak clearly and understand what you say? • Time to act fast - Call ☎ Hyperventilation FIRST AID • If casualty fails one of the FAST tests, act fast and Call • Assist casualty to adopt position of comfort • Reassure • Recovery position if unconscious • Maintain body temperature • Give oxygen if trained (Pg 36). • Monitor Vital Signs (Pg 81) ☎ New drugs and medical procedures can limit or reduce damage caused by a stroke, however, these drugs are less effective beyond the first couple of hours after the event.....therefore Call FAST. ☎ TIA (Transient Ischaemic Attack) is a mini-stroke with signs and symptoms lasting < 60mins. The risk of a stroke subsequent to a TIA is high, therefore early recognition and treatment is vital. Cerebral haemorrhage Cerebral thrombosis Hyperventilation syndrome is the term used to describe the signs and symptoms resulting from stress-related or deliberate over-breathing.

Profuse sweating occurs in an effort to lower body temperature but this leads to fluid loss and decreased blood volume (mild shock). If not treated quickly, it can lead to heat-stroke. Heat Stroke: occurs when the body’s normal cooling system fails and the body temperature rises to the point where internal organs (eg brain, heart, kidneys) are damaged: Blood vessels near the skin’s surface dilate in an attempt to release heat, but the body is so seriously dehydrated that sweating stops (red, hot, dry skin). Consequently, the body temperature rises rapidly because the body can no longer cool itself. This is a life-threatening condition. Heat Exhaustion Organs cook at 42°C (Mild – Moderate Hyperthermia) • Body Temp 37°C – 40°C Heat Stroke (Severe hyperthermia) SIGNS & SYMPTOMS • Body Temp > 40°C • Sweating • Pale, cold, clammy skin SIGNS & SYMPTOMS • Headache • NO Sweating • Muscle cramps • Red, hot, dry skin • Thirst • Nausea and vomiting • Fainting • Visual disturbances • Nausea • Irritability/ confusion • Rapid pulse • Staggering/ unsteady (Onset of mild shock due to fluid loss, Pg 14) Progresses to Heat radiates from the body, especially the head into the surrounding air • Seizures • Unconscious (Sometimes profuse sweating occurs) FIRST AID • Move casualty to cool, shaded, ventilated area. • Lie flat with legs elevated. • Loosen and remove excess clothing. • Cool by: •fanning •spraying with water •applying wrapped ice packs to neck, groin and armpits •draping wet sheet over body and fanning. • Give cool water to drink if fully conscious. • Seek medical help or if in doubt • Call ☎ Breeze or fan During breathing, cold air is inhaled and warm air is exhaled Heat is lost through evaporation (sweat) on the skin Heat is conducted from the warm body to a cold object Heat Exhaustion and Heat Stroke are usually caused by over-exertion in hot, humid conditions with poor fluid intake. Heat is lost through convection ie warm air around the body is replaced with cold air - worse on windy days Body heat can be lost quickly in high, exposed areas. Frost bite Cold Exposure Exposure to cold conditions can lead to hypothermia (generalised cooling of the body) or frostbite (localised cold injury). Hypothermia: is a condition where the body temperature drops below 35°C. • Hypothermia can be mistaken for drunkenness (Pg 59), stroke (Pg 27) or drug abuse (Pg 58). • Suspect hypothermia when conditions are cold, wet and windy, especially in the young and elderly or individuals under the influence of alcohol or drugs. • As the core body temperature drops, so does the metabolic rate which means the cells require less oxygen. Hypothermia protects the brain from the effects of hypoxia so resuscitation should be continued until the casualty can be rewarmed in hospital. MILD Hypothermia 35°– 34°C • Maximum shivering • Pale, cool skin, blue lips • Poor coordination • Slurred speech • Apathy and slow thinking • Irritable or confused • Memory loss MODERATE Hypothermia 33°– 30°C • Shivering ceases • Muscle rigidity increases • Consciousness clouded • Slow breathing hard to • Slow pulse detect • DO NOT re-warm too quickly - can cause heart arrhythmias. • DO NOT use radiant heat (eg fire or electric heater) - re-heats too quickly. • DO NOT rub or massage extremities - dilates blood vessels in skin so body heat is lost. • DO NOT give alcohol – dilates blood vessels in skin and impairs shivering. • DO NOT put casualty in hot bath as monitoring and resuscitation if needed may be difficult. Frostbite: is the freezing of body tissues and occurs in parts exposed to the cold. } SEVERE Hypothermia <30°C • Unconscious • Cardiac arrhythmias • Pupils fixed and dilated • Appears dead • Cardiac arrest FIRST AID ☎ • Call • Seek shelter – protect from wind chill (Pg 67). • Handle gently to avoid heart arrhythmias. • Keep horizontal to avoid changes in blood supply to brain. • Replace wet clothing with dry. • Wrap in blankets/ sleeping bag or space blanket and cover head. • Give warm, sweet drinks if conscious. IF NOT SHIVERING and help is delayed: • Apply heat packs to groins, armpits, trunk and side of neck. • Body-to-body contact can be used. IF UNCONSCIOUS: • DRSABCD (Pg 3) - Check breathing for 30- 45secs as hypothermia slows down everything. • If unresponsive and not breathing normally– commence CPR while re-warming casualty. SIGNS & SYMPTOMS • White, waxy skin • Skin feels hard • Pain or numbness FIRST AID • Seek shelter (Pg 67) • Treat hypothermia before frostbite • Gently remove clothing from affected area • Rewarm affected area with body heat - place in armpit (rewarming can be very painful) • DO NOT rub or massage affected area – tiny ice crystals in tissue may cause more damage • DO NOT use radiant heat • DO NOT break blisters • NEVER thaw a part if there is any chance of it being re-frozen.

How Much? • Call Poisons Information Centre for advice or Call • Monitor Vital Signs (Pg 81) • Send any containers and/ or suicide notes with casualty to hospital. • Send any vomit with casualty to hospital. ☎ FIRST AID Allergy/ Anaphylaxis Anaphylaxis is a life-threatening allergic reaction which can be triggered by nuts (especially peanuts), insect stings (bee, wasp, ant), shellfish, latex products and certain drugs (eg Penicillin). The airways rapidly swell and constrict, interfering with breathing, and the blood vessels widen, leading to shock (Pg 14). Casualties need an immediate injection of adrenaline. People who know they are at risk may wear a medical alert bracelet and carry their own injectable adrenaline. FIRST AID • Assist casualty to position of comfort. SIGNS & SYMPTOMS • Call Mild to moderate Allergic • If bite/sting is the cause - flick off sting and apply reaction: Pressure Immobilization Technique (Pg 31). • Swelling of lips, face, eyes • Follow casualty’s Action Plan for Anaphylaxis. • Hives or rash (red, itchy) • Give EpiPen/ Anapen. • Metallic taste in mouth • Record time EpiPen/ Anapen was given. • Dizziness and Weakness • Give another Epipen/Anapen if no response after 5 • Rapid pulse mins • Administer oxygen if trained (Pg 36). • Nausea • Collapse or unconsciousness - DRSABCD (Pg 3). • Abdominal cramps NB - Rescue Breaths require more force due to narrowed airways. ☎ Severe Allergic Reaction (Anaphylaxis): • Swelling of throat, tongue • Difficulty swallowing • Noisy breathing (stridor) • Wheezing • Difficulty talking/ hoarseness • Pale and floppy (young child) • Collapse or unconsciousness 1. Use EpiPen or Anapen when symptoms become severe. EpiPen and Anapen are pre-loaded auto-injecting pens containing a measured dose of adrenaline (Epinephrine). It can take 5- 20 mins for a mild allergic reaction to escalate to anaphylaxis. Hives How to Use an Anapen: (See also Pg 47) Toxic fumes from gas, burning solids or liquids. Inhaled poisons include: carbon monoxide (car exhausts); methane (mines, sewers); chlorine (pool chemicals, cleaning products); fumes from paints, glues, and industrial chemicals.

Plastic seal denotes full cylinder Cylinder key - turn anticlockwise to OPEN (on), clockwise to CLOSE (off) Heat tag - if distorted do not use Outlet valve - face outlet valve away from people before opening - high pressure gas can cause injury. Place hand under plastic tags when opening (cracking) cylinder. ‘Cracking’ purges dust from outlet valve before fitting regulator. ‘C’ sized cylinder is 490 litres. A full ‘C’ sized cylinder lasts 1 hour @ 8lpm flow rate. Fitting the Regulator: Oxygen Equipment - Care & Maintenance •Never use oil or fat-based soaps on any oxygen equipment - grease/ oil is combustible. •Never seal oxygen cylinder outlet valve with adhesive tape - glue is petroleum based. •Never allow cylinder to run empty as moisture and contaminants may enter. •If cylinder is emptied, turn off valve immediately. •Use reputable gas suppliers for refills. •Disposable items should be thrown away after use and replaced with new ones. •Masks and other parts should be checked for wear, cleaned and disinfected and dried before packing. •Follow specific cleaning instructions provided with equipment - check which chemicals are effective and compatible with particular pieces of equipment. •Any missing items should be noted and replaced. •Tubing should be coiled to prevent from kinking. •Soft masks have a tendency to distort if squashed during storage - pack carefully. •Check contents of cylinder and functioning of equipment regularly - eg after each use and/ or at start of each shift. •Oxygen units should be inspected and serviced by an appropriate trained technician as specified by manufacturer. ‘Cracking’ Cylinder • Check hands are clean and free of grease/ oil. • Ensure area is ventilated and there is no ignition sources. • Remove plastic seal from cylinder neck. • Purge outlet valve by quickly opening and closing cylinder (cracking) - see above. • Check regulator is dust and grease free and that ‘O’ ring is seated and not damaged. • Place regulator over cylinder neck ensuring index pins and index holes are in place. • Secure regulator in place by tightening ‘T’ piece - not too tight. • Set flow meter to low - this reduces pressure in regulator when cylinder is opened. • OPEN cylinder by turning cylinder key anticlockwise. • Turn flow meter OFF and listen for leaks. • Check pressure gauge - 16,000kpa (2300 psi) indicates cylinder full. • CLOSE cylinder and adjust for leaks if necessary. • If not using immediately, depressurize system - close valve, open flow meter. • Leave regulator attached and store ready for use with all valves off. Pressure Gauge ‘T’ piece (don’t use if cylinder is less Regulator Oxygen nipple than 1/4 full as flow rate is (attach tubing) Safety Pin Index coupling system for ‘C’ sized cylinder - the index pins on the cylinder correspond to the index pins on the regulator. ‘T’ piece Flow meter Cylinder neck ‘O’ ring (Bodok seal) - if damaged or not seated properly, may cause leaks - keep spares. not accurate) Regulator (reduces cylinder pressure to a usable pressure) When to use Oxygen Oxygen can be given in high or low concentration in all conditions associated with hypoxia (see below). Hypoxia is a lack of oxygen in the body’s tissues which can be caused by many conditions - generalized (eg asthma) or local (eg crushed limb). Oxygen administration will benefit the following conditions: • Respiratory distress/ Asthma (Pg 23) • Heart attack/ Angina (Pg 22) • Anaphylaxis (Pg 33) • Bleeding & shock (Pgs 12,14) • Drowning & diving emergencies (Pgs 7, 52) • Head & spinal injury (Pgs 20, 21) • Crush injury & fractures (Pgs 11, 14) • Burns (Pg 15) • Smoke/ fume inhalation (Pg 15, 47) • Drug overdose/misuse (Pg 58) • Poisoning (Pg 32) • Unconsciousness (Pg 2) • Resuscitation (Pg 37) NB. There are no absolute contra-indications to oxygen therapy (Pg 36). However, in COAD (Chronic Obstructive Airways Disease) low oxygen concentrations should be used. RESPIRATORY DISTRESS SIGNS & SYMPTOMS Mild: • Dry cough • Noisy breathing • Wheeze – during exhalation • Breathless but speaks in sentences Moderate: • Wheeze - during exhalation and inhalation • Rapid breathing • Breathless - speaks in phrases • Anxious • Pale and sweaty • Rapid pulse Severe: • Can’t speak (too breathless) • Wheeze inaudible (no air movement) • Cyanosis (blue lips) • Flared nostrils • Intercostal recession • Use of accessory muscles • Exhaustion • Distressed • Confusion or aggressive behaviour • Altered state of consciousness • Collapse - Respiratory arrest 36 | Advanced Resuscitation Advanced Resuscitation | 37 Oxygen Therapy Oxygen administration to a breathing casualty - conscious or unconscious. A conscious casualty with breathing difficulty (eg asthma or heart attack) usually finds it easier to breathe while sitting or semi-reclined. However, a casualty with shock (Pg 14) or decompression illness from scuba diving (Pg 52), is positioned horizontally. Administer oxygen (O2) to an unconscious, breathing casualty in the recovery position. Conscious Casualty: • Reassure • Position casualty appropriately • Explain what you are doing • Explain that oxygen will help • Turn on oxygen supply • Select appropriate oxygen delivery device and follow steps: Unconscious, Breathing Casualty Oxygen Delivery Devices: 1) Standard Therapy Mask - Low to Medium % O2 •Connect oxygen tubing to mask and oxygen outlet. •Open flow meter and check oxygen is flowing. •Set flow rate to 8lpm - adjust as necessary. •Position mask over mouth and nose with narrow end upwards and metal band over bridge of nose. •Pass elastic strap over casualty’s head & adjust strap. •Squeeze metal band over nose - this prevents oxygen blowing into casualty’s eyes. Some casualties won’t tolerate a mask - allow •Ask casualty to breath normally and observe. casualty to hold mask near face. 2) Non-Rebreathing Mask High % O2 •Similar to standard therapy mask but has a reservoir bag. •Set flow rate to 15lpm. •Ensure reservoir bag is inflated before fitting mask. •Fit as standard mask (above). Oxygen Delivery Device Oxygen Resuscitation Oxygen administration to an unconscious non-breathing casualty. Rescue breaths can be supplemented with oxygen (O2) during CPR (oxygen resuscitation). For inexperienced rescuers, mouth to mask rescue breathing is the preferred method. It delivers 50-70% oxygen and ventilations are performed more effectively than bag-valvemask or manual triggering devices. With all oxygen resuscitation devices, inflate until the chest begins to rise. Over inflation will cause stomach distension and regurgitation.

BVM with O2, plus reservoir, two operators Bag-Valve-Mask (BVM): Where difficulty with BVM resuscitation is experienced, two trained operators may be required - the first to manage the airway, the second to operate the bag. •Assemble the unit and squeeze the resuscitation bag to check the function of the valves. •Ensure oxygen tubing is attached to BVM and outlet valve on oxygen cylinder. •Turn on O2 supply • Set flow rate: 8-15l/min When equipment is ready: •Position mask over mouth & nose, ensuring a good seal. •Take a position behind the casualty’s head and open airway using head tilt and jaw thrust while holding mask to casualty’s face. •Deliver oxygenated rescue breaths by squeezing bag until chest begins to rise •Monitor casualty • Monitor oxygen supply. OP airways (Pg 38) can be used with resuscitation masks, bag-valve-masks and manually triggered devices to assist airway management. 38 | Advanced Resuscitation Advanced Resuscitation | 39 Oropharyngeal Airways (OPs) •Oropharyngeal airways (Guedel airways) may be necessary to maintain an open airway when using mouth to mask or bag-valve-mask ventilation. •An OP airway DOES NOT remove the need for head tilt or the recovery position. •It DOES NOT prevent suffocation by fluids or the closing of the glottis. But it does facilitate CPR by holding the tongue forward in casualties with a thick tongue. •OP airways must only be used on unconscious casualties who do not have a gag reflex. The main risks of its use are: •If the casualty has a gag reflex, they may vomit. •When it’s too large, it can close the glottis and thus close the airway. •Improper sizing can cause trauma to the throat and bleeding in the airway. Flange Sizing an OP Airway: Suction Equipment: Suction units are powered by oxygen, air, battery, hand, foot or electricity. Yankauer Suction Catheter Catheter tip Finger port (air vent) can be sealed and unsealed by operators finger to control suction Suction catheter Bite Block Collection bottle Squeeze handle to create vaccum Ear Lobe Hand Operated Suction Unit Suction tubing 2 methods for sizing OP airway Inserting an OP Airway: •Ensure casualty is unresponsive. •Clear airway using postural drainage, finger sweep and/ or suction. •Position casualty on their back. •Select correct size OP airway (above). •If lubrication is necessary, use water, casualty’s saliva or KY jelly. •Open casualty’s mouth using finger and thumb scissor motion. •Apply head tilt and/or jaw thrust (Pgs 4, 40). •Insert OP airway by following steps 1, 2, 3: Scissor motion for opening mouth 2 • Point tip of OP airway toward • When tip reaches back the roof of casualty’s mouth. of throat, rotate airway 180 Slide the airway towards back degrees. of throat. NB. If casualty starts to regain consciousness, cough, gag or vomit, remove OP airway immediately. Removing an OP Airway: •Suction helps maintain a clear airway by aspirating saliva, blood, mucus and vomit. •Suction does not remove the need for postural drainage and finger sweep to remove solid matter or viscous mucus. •Fluids and solids must be removed before and during resuscitation to maintain a clear airway. Angle of Jaw •OP airways come in different sizes. •To select the appropriate size, place OP airway on casualty’s outside cheek and measure from: •1) Centre of lips to angle of jaw or 2) Corner of mouth to bottom tip of ear lobe (see diagram). •The correct size keeps the tongue forward and maintains an open airway. 1 Suction Pull out following curvature of the tongue - no rotation necessary. Dispose of in biohazard bag (Pg 63) as it is a single use item. 3 • Advance the airway until the flange rests on the casualty’s lips and the bite block is between teeth. • Ensure lower lip is not pinched between teeth and OP airway. • Check breathing - look, listen, feel. • Maintain head tilt and jaw support. Battery Powered Suction Unit Suction Method: Oxygen Powered Suction Unit - use sparingly as depletes oxygen supply •Position casualty on side if possible, or leave on back and turn casualty’s head to the side. •Open casualty’s mouth and wipe away any large debris with gloved fingers. •Measure the suction catheter from corner of casualty’s mouth to earlobe. This gives the correct depth to insert the end of the suction tip (no further than back teeth). •Turn on the suction device and place suction tip in lower inside cheek. •If using a Yankauer suction catheter, generate suction by occluding air vent with finger. •Sweep catheter across lower cheek and aspirate for a maximum of 5 secs. •Withdraw catheter slowly from casualty’s mouth while still aspirating. •Flush line with water (place catheter tip in bowl of water and suck up) •Ensure suction bottle does not fill beyond 2/3 full.

The simplest way of ensuring an open airway in an unconscious casualty is to use the head tilt, chin lift technique (Pg 4). REMEMBER: Airway management takes priority over spinal injury. Jaw Thrust Method: • Kneel at top of casualty’s head. • Rest your elbows on the surface where casualty is lying. • Place one hand on each side of casualty’s lower jaw, below the ears (angle of jaw). • Use your index and middle fingers to push the jaw forward away from chest. • Use your thumbs to retract lower lip to keep casualty’s mouth open if necessary. • Slight head tilt may be necessary to Opening Airway Using Jaw Thrust Method maintain airway patency. Normal Heart Function Natural Pacemaker •Electrical impulses generated within the heart from a natural pacemaker, coordinate contraction and pumping of the heart. Normal Sinus Rhythm •These elecrical impulses can be recorded by an ECG (Electrocardiograph). •A normal functioning heart shows sinus rhythm on an ECG. • AEDs (Automated External Defibrillators) have an inbuilt ECG monitor which analyses the heart rhythm and determines if shock is required. Defibrillation & AEDs Defibrillation consists of delivering a therapeutic dose of electrical energy to the heart with a device called a defibrillator. A defibrillator depolarizes the heart muscle, terminates the abnormal rhythm, and allows normal sinus rhythm to be reestablished by the heart’s natural pacemaker (Pg 40). The delay to defibrillate is the most important factor in determining survival from cardiac arrest. For every minute without defibrillation, survival declines by 10% ie 50% survival after 5 mins delay. % Survival Jaw Thrust Time to Defibrillate (mins) Automated External Defibrillators (AEDs), are simple-to-use units designed to analyse the heart rhythm and inform the user if a shock is advised. Preparation of Casualty: 1) Expose chest - cut clothing. 2) Remove any medication patch or jewelry. 3) Wipe chest dry, remove chest hair with razor. AED Pad Position AED Set-Up and Operation: Left Atrium LA RA Left Ventricle LV RV Abnormal Heart Rhythms Electrical Impulse • During cardiac arrest, ECGs will detect abnormal elecrical activity (heart rhythms). • The following 3 heart rhythms are associated with cardiac arrest: Ventricular Fibrillation (VF): • VF is the most common rhythm in cardiac arrest. • The heart quivers but doesn’t pump. • VF lasts a few minutes before all electrical activity ceases (asystole). • VF is a shockable rhythm - asystole is not (see below). Ventricular Tachycardia (VT): • The heart beats too fast to pump effectively (pulseless VT). • VT may progress to VF then asystole. • VT is a shockable rhythm. Asystole (flat line): • Asystole is a non-shockable heart rhythm. • All electrical activity has ceased and survival is unlikely. AEDs only shock two rhythms - VF and VT (not asystole) 1) Turn it ON. 2) Attach AED Pads - peel backing off first. 3) Follow voice prompts. AED Voice Prompts: •If voice prompt advises ‘check electrodes’ you should check: 1) Pads are sticking properly to chest (wipe chest dry/ remove chest hair). 2) Pad connection cable is plugged in and pads are positioned correctly. •If voice prompt advises ‘shock now’ ensure nobody is touching the casualty when the shock is delivered. SHOUT ‘stand clear’, then press shock button. •If voice prompt says ‘no shock advised’, check responsiveness/ breathing and follow voice prompts. Children and AEDs: •Standard adult AEDs and pads are suitable for the use in children older than 8 years. •Ideally, for children between 1 and 8 years, paediatric pads and an AED with a paediatric capability should be used. •Pads should be placed in the same way as an adult (See illustration above, AED Pad Position). •If an AED does not have a paediatric mode or paediatric pads then the standard adult AED and pads can be used. •Ensure the pads do not touch each other on the child’s chest. This may require one pad to be placed on the centre of the chest and the other on the back of chest between shoulder blades. Note: •AEDs should only be used on unresponsive, non-breathing casualties. •An AED can and should be used on pregnant casualties. •In large-breasted individuals, place the left electrode pad lateral to or underneath the left breast. •If the casualty has an artificial, implanted pacemaker, a scar and raised area will be seen just below the left or right collar bone. Position AED pads 8cms from the pacemaker unit and proceed as usual. •An AED analyses the heart rhythm every 2 mins and continues for up to 5 hrs or 150 shocks depending on make, model and battery life of AED. DO NOT bump casualty while AED is analysing rhythm. •AED batteries and pads have expiry dates. •AED packs should include: razor, scissors, hand towel, spare pads, gloves and face shield. •AEDs conduct automatic internal checks and provide visual indicators that the unit is ready and functioning properly - no need to turn on daily - follow manufacturer guidelines. 42 | Advanced Resuscitation Cardiac Arrest Advanced Resuscitation | 43 (See also Pg 22) • In cardiac arrest the heart stops beating and pumping properly resulting in cessation of normal blood circulation (no pulse) • Arrested blood circulation prevents delivery of oxygen to the body • Lack of oxygen to the brain causes unconsciousness and absence of breathing (respiratory arrest) • This is a medical emergency which if treated early is potentially reversible • Treatment involves CPR to provide circulatory support, followed by defibrillaton if a shockable rhythm is present • If a shockable rhythm is not present after CPR and other interventions, survival is unlikely. Causes of Cardiac Arrest: • Heart attack (blocked coronary artery) - 70% of all cardiac arrests. • Massive blood Loss • Drug overdose • Drowning • Pulmonary embolus (clot in lung). • Electric shock • Anaphylaxis • Airway obstruction (choking, severe asthma). Chain of Survival (See also Pg 5) Defibrillation is NOT a standalone treatment for cardiac arrest. All links in the ‘Chain of Survival’ must be in place to increase survival. Time is the essence. The 4 steps in the chain of survival are: 1) Early Access 2) Early CPR 3) Early defibrillation 4) Early advanced life support Advanced Resuscitation Techniques Advanced Resuscitation Techniques Two Operators: • If two rescuers are available, one rescuer commences CPR while the other: 1) Calls 2) Retrieves the AED. 3) Retrieves oxygen equipment. • Minimise interruption to CPR (Pg 4,5) while the second person sets up and attaches AED pads to casualty’s chest. • While AED analyses the heart rhythm (takes 10-20 secs), CPR is stopped and oxygen resuscitation equipment is set up (Pg 8,11). • One rescuer takes up position above the casualty’s head and is responsible for managing the airway and forming a good seal with the resuscitation mask. • The second rescuer is positioned at the side of the casualty and performs chest compressions, rescue breaths (squeezes the bag) and operates the AED. •Follow AED voice prompts (Pg 41). •Rescuers swap roles after 5 cycles of CPR (2 mins) to avoid fatigue. • Continue until: 1) Casualty responds or begins breathing normally. 2) Rescuers become exhausted. 3) Health professional arrives and takes over. 4) Health professional directs that CPR be ceased. ☎ 1 Single Operator: • If there is one rescuer and an AED is immediately available, set up AED (Pg 41) before commencing CPR (Pg 4,5) • While waiting for the AED to analyse the heart rhythm, set up oxygen equipment (Pgs 34, 37) and position yourself above the casualty’s head. and place on loud speaker. • If you have a mobile phone, call • Follow AED voice prompts (Pg 41). • Perform chest compressions and oxygen resuscitation from above casualty’s head. • Continue until: 1) Casualty responds or begins breathing normally 2) Rescuer becomes exhausted 3) Health professional arrives and takes over 4) Health professional directs that CPR be ceased. 2 3 ☎ 1 2 3 If casualty regains consciousness: • Roll casualty into recovery position. • Administer oxygen via standard face mask. • Turn off AED. • Keep AED pads attached to chest in case casualty relapses into cardiac arrest. • Monitor and reassure casualty. Note: Recovery Position with Oxygen & AED •Rescuers must communicate with each other to keep the resuscitation process flowing. •It is vitally important that CPR is not interrupted while the AED and oxygen is set up. •Resuers should use the 10-20 sec window while AED analyses heart rhythm to swap roles and re-organise. 44 | Low Voltage Rescue Low Voltage Rescue | 45 What is Electric Shock? What is Arc Flash? An electric shock can occur upon contact of a human's body with any source of voltage high enough to cause sufficient current through the muscles or hair. Arc Flash is a short circuit that flashes from one exposed live conductor to another, or to the ground. ● Death caused by an electric shock is referred to as electrocution. ● The greater the current, the greater the shock! ● The severity of electric shock depends on voltage, amperage, and resistance. Always test a circuit to make sure it is de-energized before working on it. Power drills use 30 times more power than will kill! What can Electric Shock do to me? LOW VOLTAGE = less than 1000V AC or 1500 V DC LOW VOLTAGE DOES NOT MEAN LOW HAZARD! The Arc Flash produces intense: ● Heat (> 5000 degrees causing severe burns) ● Light (The same light radiation as welders) ● Pressure wave (blast) equivalent to several sticks of dynamite and can break bones and cause internal organ damage. ● Arc Flash can result from inserting a tool in the wrong place or dropping a tool into a circuit breaker or service area. ● 80% of all injuries and fatalities caused by electrical incidents are caused by Arc Flash…… not electric shock! What is Flash Burn? Flash Burn also known as Arc Flash, Arc Eye or Welder’s Flash, is a burn sustained from an electric arc either by the extreme heat it produces or through UV radiation. SIGNS & SYMPTOMS Effects of Electrical Current on the Body (Less than 600 Volts) •Minor Flash burn to the eyes becomes painful and ‘gritty’ about 2-3hrs after the event. Current Reaction 1 milliamp Just a faint tingle FIRST AID 5 milliamps Slight shock felt. Disturbing, but not painful. Most people can “let go.” 6-25 milliamps (women) Painful shock. Muscular control is lost. This is the range where 9-30 milliamps (men) “freezing currents” start. It may not be possible to “let go.” 50-150 milliamps Extremely painful shock, respiratory arrest (breathing stops), severe muscle contractions. Flexor muscles may cause holding on; extensor muscles may cause intense pushing away. Death is possible. 1,000-4,300 milliamps (1-4.3 amps) Ventricular fibrillation (heart pumping action not rhythmic) occurs. Muscles contract; nerve damage occurs. Death is likely. 10,000 milliamps (10 amps) Cardiac arrest and severe burns occur. Death is probable. 15,000 milliamps (15 amps) Lowest overcurrent at which a typical fuse or circuit breaker opens a circuit! What type of injuries follow Electrical Accidents? ● Cardiac Arrest ● Respiratory arrest ● Burns/ Tissue damage Electrical Burns cause Massive Tissue Damage: This worker fell and grabbed a powerline to catch himself. The resulting electric shock mummified his first two fingers, which had to be removed. The acute angle of the wrist was caused by burning of the tendons, which contracted, drawing the hand with them. Generally flash burns resolve within 36 hrs. Minor Flash Burn to Eyes Seek urgent medical help if any of the following occurs: (This is common when welding • Blurred vision • Vision changes • Seeing spots or flashes of light without protective eyewear). • Pain on moving eyes • Worsening pain • Casualty concerned about eyes This man was near a power box when an electrical explosion occurred. He did not touch the box, but electricity arced through the air and entered his body. The current was drawn to his armpits because perspiration is very conductive. This is severe flash burn caused by an Arc Flash. The explosion caused airway burns and embedded molten copper into the casualty’s eyes, resulting in permanent blindness. FIRST AID ☎ • Apply burns dressing • Move to safety • Call • For airway burns - see below What is Airway Burn? Smoke, steam, superheated air or toxic fumes from Arc Flash explosions can cause severe damage to the airways resulting in swelling and possible airway obstruction. •Look for evidence of inhalation injury around nose or face (see photo above). •Coughing or hoarseness may indicate exposure.

High resistance of the skin transforms electrical energy into heat energy, producing burns. Electrical burns are often associated with an entry and exit point and are usually more severe than they appear due to massive internal tissue damage. Entry Wound: The dark dot in the centre of wound is a burn at the entry point. This man was lucky - the current narrowly missed his spinal cord. FIRST AID • Move to safety • Call ☎ Exit Wound: Current flows through the body from the entry point, until finally exiting where the body is closest to the ground.

Chin piece Rescuer 2 secures collar with velco tab. Ensure collar is firm and comfortable, adjust if necessary. Rescuer 1 maintains head and neck support during all adjustments Size adjuster Velcro strap Chin piece Adjustable Cervical Collar If a casualty with suspected spinal injury must be moved, follow these guidelines: •Immobilise the lower limbs by applying a figure of 8 triangular bandage, around the feet (Pg 11). •Secure casualty’s hands. •A minimum of 6 people are required to perform the lift where possible. •The person at the head of the casualty is in control of the lift and must ensure that alignment of the spine is maintained. Scoop Stretcher Clamp together Wider head end •A scoop stretcher splits vertically into two and the sections fit around the casualty lying on the ground. The sections are reconnected and the casualty is lifted. •Both sides of the casualty must be accessible to use a scoop stretcher. •Scoop stretchers are length adjustable to fit the height of the casualty. •Particular attention must be paid to the closure area beneath the casualty so that clothing or skin is not pinched or trapped. •Scoop stretchers can be used as a transport device provided the patient is strapped. •Scoop Stretchers are uncomfortable for the casualty and transfer to a spinal board or vaccum mattress is preferable - place the scoop stretcher on top of the transport device and unclamp. Spinal Board Head Block A spinal board (backboard) is designed to provide rigid support during Strap transport of a casualty with suspected spinal injury. •A casualty is transferred onto a spinal board using a scoop stretcher (Pg 48) or the log roll technique (Pg 21). •Spinal boards are almost always used in conjunction with the following devices: • Cervical collar (Pg 48) • Side head supports to minimise lateral rotation of the head (head blocks or roll blanket). • Straps to secure casualty’s head and body to the board. •Spinal boards are usually plastic, light weight and are slightly longer Spinal and wider than the average human body to accommodate immobilisation Board straps and handles for carrying. •Most spinal boards are buoyant and are X-ray translucent. •It is advised that no casualty should spend more than 30 mins on a spinal board to avoid discomfort and pressure sores. If casualty becomes unconscious and/or vomits/regurgitates while strapped to a spinal board or vaccum stretcher (below): • Tilt the stretcher onto it’s side to clear airway (postural drainage) • Assess casualty’s airway and breathing - DRSABCD (Pgs 2-5) Vaccum Mattress •The vaccum mattress is used to immobilise and transport casualties with spinal, pelvic or limb trauma. •It can be used as a standalone transportation device or placed on top of a stretcher. •The vaccum mattress consists of a sealed polymer bag filled with small polystyrene balls and a valve. The mattress is flexible and moulds to shape but when air is pumped out through the valve, the polystyrene balls squeeze together forming a rigid structure. •The conforming nature means that casualties can be Handle kept immobilised on it for longer periods of time. Strap •It is washable and x-ray translucent. Valve •A sheet is usually placed on the inside of the mattress Vaccum Mattress for three reasons: 1) To protect the mattress from puncture - the casualty might be wearing sharp jewellery or have broken glass on their clothing. 2) To reduce sweating - the polymer material is not breathable. 3) To help transfer casualty in the emergency room. Basket Stretcher Basket Stretcher A rigid basket stretcher can be used to transport a casualty across uneven terrain from a remote location that is inaccessible by ambulance or other vehicle. If a spinal injury is suspected, the casualty must first be immobilized on a spinal board (above) then the spinal board placed into the basket stretcher. Basket stretchers surround and support the casualty yet their design allows water to drain through holes in the bottom. Basket stretchers with special ratings can be used for specialised rescues (eg helicopter, water and technical rope) but rescuers must have special training. 50 | Advanced First Aid Advanced First Aid | 51 Helmet Removal (See also Pg 21) Full face helmets should only be removed if the casualty is unresponsive and the airway cannot be maintained or resuscitation is required. Call ☎ Harness Suspension Trauma If casualty is conscious, leave helmet in place. Support head and neck. Remove helmet ONLY if casualty becomes unresponsive and airway cannot be maintained. Removing a helmet requires two people: 1 immobilises 1 Rescuer casualty’s head and neck. 2 continues supporting 4 Rescuer head and neck while rescuer 1 removes the helmet. 2 removes 2 Rescuer obstructions ie opens viser, removes glasses and unfastens chin strap. 2 carefully 5a Rescuer lowers the casualty’s head and neck into the neutral position. 2 supports casualty’s 3 Rescuer head & neck by placing a hand behind neck and the other supporting the jaw.

Head tilt Suspension trauma (orthostatic shock) occurs when the body is at rest in a vertcal position with the lower body motionless for a prolonged period of time (5 - 30mins). As a result, blood pools in the lower extremities, blood pressure drops, the brain is deprived of oxygen and fainting (Pg 24) occurs. However, fainting while suspended vertically can lead to death. Those at Risk: Anyone immobilised in a vertical position is at risk: • Rock climbers • Cavers • Circus performers • Stretcher casualties • Confined space workers. Factors affecting the degree of risk: • Dehydration • Hypothermia • Fatigue • Ability of the person to move their legs. Prevention: •Ensure harnessed is person well hydrated, warm and not fatigued before commencing activity. •Cease activity if fatigue, dehydration or hypothermia develops. •Wear a good fitting harness. •Ensure everyone in the group is trained in single rope rescue techniques. •Avoid hanging motionless....keep legs moving. •Ensure everyone in the group is aware of signs and symptoms of suspension trauma (below). •Have a buddy system and communicate continually....don’t work alone. •Have a group risk management action plan. If symptoms occur and casualty is still conscious: •Alert buddy and activate action plan to get casualty to ground ASAP. •If casualty is stranded and there is something to kick against or stand on (eg rock ledge or caving leg-hoops) use leg muscles by pushing against it every so often to keep blood pumping back to torso. •If casualty is stranded in mid-air or is exhausted, raise legs to a sitting position which can be done with a loop of rigging tape behind the knees or specialised rescue equipment. NB. Pedaling legs should only be used as a last-ditch effort to prolong consciousness, as pedaling quickly fatigues leg muscles which demand blood.

Pain Management Techniques: • Reassurance • Position casualty or part of the body to minimise pain. • Distraction & relaxation techniques to diminish awareness of pain. • Maintain casualty’s privacy & dignity to minimise discomfort. • Analgaesia - Assist casualty to self administer own analgaesics when appropriate. As a general rule, first aiders should not give pain relief medication. First aiders can assist a casualty with their prescribed medication or medication which the casualty chooses to take independently. In the workplace, follow the established guidelines for the use of pain-relieving medication. Entonox Contents gauge Single pin index connection •Entonox is an analgaesic gas composed of 50% nitrous oxide (laughing gas) and 50% oxygen. Demand valve •The gas is self administered through a demand valve, using a mouthpiece, bite block or face mask and is often used in dental proceedures or childbirth. •Entonox offers fast acting pain relief (2mins), wears off quickly and has few adverse effects (drowsiness). •Entonox is a ‘Prescription Only Medicine (Schedule 4 drug) and authorisation to administer is required from a medical authority. •There is no risk of overdose as the casualty’s level of consciousness governs his/her ability to maintain flow of gas. Entonox Equipment: Flexible tubing •Entonox cylinders are blue with a white quartered shoulder and have a single pin index mounting on the cylinder neck. •Store cylinder horizontal and above freezing, if possible. •If a cylinder is stored below -5ºC, the gases will separate - re-warm Entonox cylinder cylinder and invert at least 3 times. Before Administering: •Seek permission from a medical authority to administer Entonox. •Ensure airway is clear (no vomit). •Ensure casualty can breath deeply enough to operate the demand valve. •Ensure casualty is fully conscious and compliant with instructions for self administration. •Advise casualty about the possibility of drowsiness. •Supervise casualty at all times by a person trained in Entonox administration.

Cut to Face Puncture Wound Caused by a rusty nail, thorn, animal bite, is on sole of foot or over a joint. Foreign material Even a small cut on the face may require suturing to prevent scarring. Wound Infection eg unable to remove (see above) grit from a wound Treated with antibiotics. Animal bite Risk of infection •A tetanus shot is required if the wound is caused by an animal bite, puncture wound or the wound is dirty and your last tetanus shot was greater than 5-10yrs ago. •DO NOT delay suturing - wounds older than 8-12hrs are sutured with a skin drain in place or cannot be sutured at all as the risk of wound infection becomes too great. Example of Good Wound Care Management: Deep Laceration 1 Bleeding was controlled (Pg12), wound cleaned (Pg 61), then checked for damage and embedded objects. 2 Wound was sutured, cleaned and dressed daily for two weeks and antibiotics were prescribed. 3 1 yr later - no complications and the scar is bearly visible Great result! Infection Control (See also Pgs 72 & 80) Every employer is required under an Occupational Health and Safety Act to provide a safe workplace for employees and visitors; including providing adequate infection control procedures and suitable training and equipment. • Infection control is achieved by preventing pathogens being transmitted from one person to another. • The basis of proper infection control is to assume that all persons are potentially infectious. • Basic infection control procedures include hand washing and keeping the workplace clean. Spreading of infection: Infectious agents (pathogens/ contaminants) can be spread in a number of ways, including: • Airborne - coughing or sneezing releases airborne pathogens, which can be inhaled by others. • Skin-to-skin contact - some pathogens can transfer through touch, or by sharing personal items such as clothing, helmets, or other objects. • Contact with body fluids - contaminants in blood, saliva, urine or faeces can be transmitted to another person via cuts or abrasions, or through the mucus membranes of the mouth and eyes. • Contaminated objects or food - if hands are not properly washed, contaminants from a person’s faeces may be spread to food; surfaces, and other objects. Managing spills of body fluids: Body fluids include blood, saliva, urine and faeces. When managing spills of body fluids, the organisation’s infection control procedures should be followed carefully. You must: •Isolate the area by using signage and/or barricades. •Wear gloves, a plastic apron and eye protection such as goggles. •Soak up the fluid with disposable paper towels, or cover the spill with a granular chlorine releasing agent for a minimum of 10 minutes. •Scoop up granules and waste using a newspaper (or similar) and place in a plastic bag and dispose of properly. •Mix one part bleach to 10 parts water and apply to the area for 10 minutes. •Wash with hot water and detergent. •Dry the area. •Dispose of paper towels and gloves properly. •Wash your hands with an appropriate cleaning agent. •Rinse contaminated clothing in cold running water; Soak it in bleach solution/disinfectant for half an hour; Wash separately from other clothing with hot water and detergent. Infectious or Biohazard Waste: When disposing of infectious waste you should: • Wear heavy duty gloves and other appropriate protective clothing. • Place waste in plastic bags marked Infectious Waste or Biohazard. • Dispose of waste in accordance with Enviroment Protection Act (EPA) regulations. 64 | Workplace First Aid Establishing a Workplace First Aid Plan Step 1 - Establish your Workplace’s First Aid Needs: The factors that determine your organisation’s most effective first aid plan depend upon the specific activities of your workplace and the industry in which you operate. Your workplace situation can be assessed using the following 3 steps: 1. Hazard Identification - Identify hazards in your workplace. Hazards are things that can cause harm (e.g. machinery, chemicals, working at heights). 2. Assess Risks - Assess the health and safety problems in the workplace - who is in danger, what injuries could occur (eg cuts, burns, heat exhaustion), the factors contributing to the danger and how likely they are to occur. 3. Control or Eliminate Risks - ie make changes to protect people. For example train employees, develop safety proceedures, replace hazardous chemicals, guard machinery or as a last resort use personal protective equipment (PPE). Step 2 - Assess First Aid Requirements: What type of work is performed? - Restaurant workers will have different first aid requirements from those working in an oil refinery. What type of injuries and illnesses are likely? - eg cuts, burns, chemical poisoning or crush injuries. Also consider common medical problems which may occur amongst employees eg epilepsy, asthma, diabetes or angina. Locality and Number of employees - regulations may require a minimum number of trained first aiders per number of employees, including during shift work and overtime. Employees with disabilities - consider first aid needs and access issues of employees with disabilities or special needs. Workplace layout - first aid facilities must be appropriate for the type of work being performed in different work areas. Location of workplace - proximity of the workplace to medical centres, hospitals or ambulance Step 3 - Develop a Written First Aid Action Plan: • How many trained first aiders are needed? (Consult with OHS body/industry regulator). • What are the training and qualification requirements for your first aiders? • What is your Standard Operating Procedure when an employee requires first aid? • Is a first aid room required and how should it be managed? • What are your requirements for first aid kits? - • Contents (this will depend on your workplace hazards, and the types of injury/illness likely to occur) • Number of kits • Location of kits • Signs (clearly identified) • Information (contents list, emergency numbers) • Management (assessing kit requirements, checking & replenishing contents). • What system do you have in place for managing and maintaining first aid records? Step 4 - Implement the First Aid Action Plan: Nominated first aider officers need: • Wrtten documentation outlining your organisation’s First Aid Plan to ensure they understand their specific role and responsibilites. • Ongoing training to maintain and update skills. • Input towards developing and implementing the organisation’s first aid management plan. Employees must be provided with: Information about first aid during induction, and also at formal regular intervals. Language and literacy needs of all employees must be considered and taken into account. Workplace First Aid | 65 Employees must know: • Where to go if first aid assistance is required • Who the first aider officers are in the workplace • What role they have if a first aid incident occurs (e.g. reporting incidents and accidents to supervisors). This information may be communicated by: • Information sessions • Induction training • Posters or signs in the workplace • Newsletters, emails or memos. Step 5 - Evaluate First Aid Action Plan: • Organise a mock first aid emergency to check that your first aid plan works. • If an incident requiring first aid does occur, evaluate the effectiveness of the first aid provided, and make changes to your first aid plan if necessary. • If new information is obtained about a previously unidentified hazard, review your first aid system. Being prepared for an OHS Inspection: A WorkCover Inspector will most likely ask the following questions about your first aid set-up: • What have you documented in regard to your first aid procedures? • What type of injuries or illnesses has the workplace had over the last 5 years? • What kinds of hazards are there in the workplace and what is the organisation doing to advise and protect its employees and visitors? • Is there a qualified and nominated first aid officer(s), trained to administer first aid? • Show me the first aid kit(s). • How many people work on this site, and show me how they access first aid? • Who is responsible for keeping your first aid documentation up to date? • How do employees and visitors know what to do and where to go if there is an injury or illness requiring first aid? First Aid Room State and industry regulations determines if your worplace is required to provide a First Aid room. Suggested items for a First Aid Room: Furniture & Fittings: • Sink with hot and cold water supplies. • Cupboards for storage of linen and supplies. • Desk, work bench or dressing trolley. • Telephone • Electric power points. • Lockable filing cabinet for record keeping (Pg79) • Suitable seating • Couch (waterproof surface) with blankets and pillows. • Moveable screen, suspended curtain, or a door that can close for privacy needs. Medical Requirements: • Examination table • Examination lamp • Stretcher, lifting frame or similar device for transporting patients • Container safe disposal of needles or other sharp implements • Container fitted with disposable bag or liner for soiled dressings and gloves • First aid kit appropriate to the workplace • Soap, disposable towels, trays, gloves and bowls. Documentation and Information: • First Aid Incident/report form (Pg 79) • Daily Attendance Record Form • Injury/illness statistic summary form (detects trends and evaluates safety proceedures) • First Aid Action Plan • Names and contact numbers of first aiders and external emergency organisations. 66 | Remote First Aid Remote First Aid | 67 Travelling to a Remote Area A remote area can be defined as one in which medical care is more than one hour away. Parties travelling to remote areas should be well organised and experienced. Planning & Preparation: When preparing for a trip to a remote area, plan for the unexpected: • Injury/ illness • Getting Lost • Change in weather •Trip takes longer than predicted. Your provisions and equipment depends on the number of participants, duration, and likely conditions. Consider: • Food • Water (litres per day per person) • Clothing • Shelter • Fire • First aid kits • Medications and repeat scripts • Communication devices • Insurances • Vaccinations • Fitness and ability of group members • Medical history of group members. If going overseas to a remote area: •Get a medical and dental checkup prior to your trip. •Speak to a travel doctor who understands the environment you are travelling to. •Check medication is not heat or cold sensitive - asthma puffers don’t work in extreme cold. •Some medications are illegal in certain countries - check with your travel doctor. •Check your prescribed medication is compatible with medications in your first aid kit. •Ensure your travel insurance covers emergency evacuation by helicopter. Some countries require proof of ability to pay. Leave credit card details, insurance cover or cash with travel agent, embassy and/ or next-of-kin. Team Leaders: •Register and de-register your trips - this involves notifying authorities and friends of your planned route and estimated time of arrival. When you arrive at your destination, notify friends and authorities immediately. •Check weather and other pertinent condition reports. •Talk to members with a chronic medical condition and have them explain how to deal with any possible emergencies (eg testing a diabetic blood sugar level, dealing with asthma attack). •Give regular briefings to your group and local staff on what to expect on the next stage of trip. •Don’t overestimate group abilities. Buddy System: •Always allow time for the unexpected. •Pair up everyone in group with •Don’t go faster than the slowest member of your group. instructions to keep an eye on •Use the buddy system to monitor individual progress. each other. •If someone is not well, (Pg 71) stop as soon as it’s safe to •Any signs of general unwellness do so and follow up the problem.

Stores water. •Iodine or chlorine tablets - purifies water (Pg 68). •Vitamin C tablets - removes iodine and chlorine taste from water. Boosts immune system. •Salt tablets - replenishes salt after sweating. •Thermal blanket & black garbage bag - sleeping bag, roof for shelter, collects rain water, carrys firewood, signaling device, marks trail when torn into strips. •Wire saw - sawing wood for fire or shelter. LOST or Injured 1 Sit down, stay put, stay calm. Think through your situation, take stock - assess resources and needs. Observe your surroundings. Plan your survival - in most cases the priority should be: • Make a SHELTER • Build a FIRE • SIGNAL • Find WATER 2 SURVIVE •Shelter is the means by which your body is protected from excess exposure to sun, cold, wind, rain or snow. •Anything that takes away or adds to your overall body temperature can be your enemy. Black Garbage •Clothing is the first line of shelter protection - have the Bag right clothes for the right conditions. •Wear a hat - protects from the sun and preserves body heat in the cold. •Keep the layer closest to your body dry. •Layers trap air and are warmer than one thick layer. •Do not expend energy making a shelter if nature provides one. •Space (thermal) blanket prevents dampness, insulates your shelter, collects rain water, makes a solar still (Pg 68), conserves body heat and makes a good reflective signaling device. •Black garbage bags make a good alternative to space blankets. Space /Thermal blanket SHELTER FIRE Fire can purify water, cook food, signal rescuers, provide warmth, light and comfort and help keep dangerous predators at a distance. The smoke keeps flying insects at bay. Outdoor adventurers should have a minimum of two ways of starting a fire - eg a flint striker and waterproof matches on their person, and with their gear. To make a fire you need to build up gradually beginning with tinder, then kindling, then small pieces of wood progressing to larger pieces. Tinder is dry material that ignites easily eg paper, leaves, grass, bark, resin, cotton wool. Kindling is readily combustable material that is added to burning tinder eg small twigs and pine cones. Dead tree branches make good fuel wood. •Collect enough fire wood for the night, then collect the same again. •Carefully bank your fire to prevent igniting surrounding areas. •Conserve fuel by making a fire where the ends of large logs meet the fire only - push inward as more fuel is needed. •Make a refector from your space blanket on the back wall of a shelter to reflect the heat of your fire to your back. •Sit between fire and back shelter wall. •Never leave a fire unattended. •Extinguish fire before leaving camp. 68 | Remote First Aid Remote First Aid | 69 Survival in Special Circumstances SIGNAL FOR HELP If you don’t have a mobile phone, satellite phone, two way radio, whistle or Radio Distress Beacon (Pg 74) you will need to use visual signals. Select a good signal site close to your shelter with good visibility such as a clearing, hilltop or lakeshore. A search will probably start from your last known location and sweep over your proposed route. Lightning •If you hear thunder, a storm is within 16km of you. •Lightning strikes can occur within 10km of a storm. •The scene is not safe until 30mins after the last thunder. Whistle 3 short blasts Fire & smoke, flashing light, bright coloured markers, flags, flares and reflective devices can be used to create a visual distress signal. (NB. Using fire & smoke as a distress signal is potentially dangerous). •Find shelter in a building or vehicle - tents offer no protection and small open shelters, very little. Flare Torch Flash 3 times SOS (Safe Our Souls) is the best known international distress signal. The SOS signal can be transmitted by any method, visual or audio - 3 short, 3 long, 3 short. Pause. Repeat signal. If difficult to produce long and short signals, any signal repeated 3 times will serve as a distress signal. Three fires built in a triangle or straight line is recognised as a distress signal. On a sunny day use a mirror or shiny object as a signaling ‘V’ Sheet EPIRB device. A canteen cup, belt buckle, thermal blanket or mirror(Pg 74) signaling-compass flashed 3 times serves as a distress signal. Construct ‘SOS’ with rocks, logs or clothing as a ground to air signal. If an aircraft recognises your distress signal, the pilot will respond by: Rocking the aircraft’s wings (daylight) or flashing the aircraft lights on and off twice (night) Lack of the above indicates that the message has not been understood. WATER Collecting water: Survival is unlikely if you go: 30 hrs 3 days 30 days 3 mins without O2 without shelter without water without food •Never wait until you are out of water before collecting it. •Select the cleanest water from the best site - running rather than still, and above villages. •Catch rainwater in your space blanket by laying it out in a trench. •Use Transpiration Bag, Solar Still or Beach Well method to collect water (see diagrams below). •Polyzip bags are good for collecting and storing water. •Contaminated water can cause diarrhoea so purify before drinking (see below). Transpiration Bag plastic bag Solar Still dirt anchor green foliage creates moisture Water Purification - 2 Methods: Beach Well container plastic sheet rock weight container ocean hole dig for water saturated sand 1) Boiling - Strain large particals using a shirt or handkerchief before boiling for 10mins. This is the best method of purification but requires a container and fire. 2) Chemical Tablets - (Iodine or Chlorine). Strain water as above then add tablet and swirl around. Leave 30mins before drinking. To remove iodine taste, add 1/2 Vitamin C tablet. •A motor vehicle or caravan with a metal roof protects but avoid touching the metal sides. •If no buildings or vehicles, seek shelter in low areas under a thick growth of small trees or shrubs or in concave ground ie valleys or dry ravines. Feet together Hands off ground Crouch Position Insulate •If you are on a boat, get in the cabin and stay away from any metal or electronic components. •If the boat has no cabin, adopt the crouch position - feet together, hands off floor. •Avoid open ground, water, tall isolated trees, masts, pylons, summits, wire fences and tent poles. •Place any metal (eg walking poles, ice axes, umbrellas) well away from you. •Remove jewelry, hair clips, belt buckles, steel capped boots or other metal objects . •DO NOT use electronic equipment (eg two-way radio or mobile phone) during a storm. •If in an open area, assume the crouch position with feet together and hands off the ground. •If possible, insulate under your feet with eg rain jacket, foam mat, plastic bag. •If in a group, seperate each member at least 10m apart and all adopt the crouch position. •Some victims are struck directly by lightning but others electrocuted from ground current. •DO NOT lie flat on the ground as this increases your chances of ground current electrocution. •It is safe to touch and help a lightning victim as they are not ‘electrified’. •Lightning injuries include cardiac arrest (Pgs 22, 42) and severe burns (Pg 15). Floods •Stay alert during stormy weather - heavy rain upstream could send flash floods your way without you ever feeling a drop of rain. •Know where streams and rivers run and local safe zones of higher ground. •Avoid camping at the bottom or gullies and dried river beds during wet season. •If you see or hear water rising, or notice water turning muddy, climb to the nearest high point and wait out the flood or call for emergency assistance if necessary. •Do not cross flood water more than ankle deep especially when an obvious current exists. •If crossing, beware of objects in the water eg broken glass, torn metal, splintered wood and electrical wires - wear appropriate foorwear. •Being a strong swimmer in flood water may not save you as most people are killed from the impact of objects such as logs or rocks. •Flood water is often polluted by sewage and if swallowed may cause infection. •If in a vehicle, avoid driving into flood water more than knee deep. •If you have a radio or TV, stay tuned to local weather reports, warnings and evacuation information. Heed warnings and immediately follow all instructions. 70 | Remote First Aid Remote First Aid | 71 Early Signs of General Unwellness: Snow If injured or lost: • Seek shelter - if snow is deep, build a snow cave on the leeward side of a hill or under a tree. This is strenuous exercise which will generate body heat. Pace the exercise to prevent sweating as this increases cooling. • Stay warm - Consume calories, rehydrate, keep your Shelf for body moving, build a fire (Pg 67), if wet get dry. Ensure sleeping bag the layer of clothing next to your skin is dry. • Rehydrate - Do not eat snow as this chills your Snow Cave Under a Tree system. Pack snow into a flask and place under Wind direction clothing to melt. • Make yourself visible - Cross your skis or stomp a Vent - ski pole large ‘X’ in the snow. Display bright clothing or use keeps it open other visual distress signals (Pg 68). Shelf for sleeping bag • Use your PBL (Pg 74) if you have one. If your trip is registered (Pg 51), help should not be too far away - wait for rescuers. Injury from cold exposure includes hypothermia and frostbite (Pg 29). Bushfire Dehydration: Dehydration is loss of body fluid resulting from excessing sweating, diarrohoea, vomiting, burns and/or blood loss. 2-3 litres of water is lost daily through sweating and urination but increases during exertion, at high altitude and windy conditions. Drink 2 litres of water per hr in hot strenuous activities. Snow block seals entrance Snow Cave on a Slope Bush fires have 3 deadly qualities: 1) Radiant heat so intense as to induce heat stroke (Pg 28) 2) Smoke and hot gases causing asphyxiation (Pg 47) 3) Flames causing direct burns (Pg 15) If trapped on foot: •Go to an area that is already burnt or free of fuel. •DO NOT try to run through a fire front. •DO NOT try to out run the fire, move to it’s flanks. •Move downhill to a low fuel area. •Seek shelter in a large water mass (river, waterhole) on the side furthest from the fire. •DO NOT climb into water tanks as this water heats rapidly, possibly to boiling point. •If no water, hide behind a raised object - a log, rock or tree stump in a fuel free clearing. •Seek shelter away from potential fuel and cover any exposed skin with dirt or clothing. •In bare areas, find hollows in the ground, eg wheel ruts, which offer some protection. •If possible lie face down with feet towards the oncoming fire. •Protect your airway using a damp cloth or clothing. If trapped in a vehicle: • Grumble • Mumble • Stumble • Tumble Heat Exhaustion (Pg 28); Hypothermia (Pg 29); Low blood Sugar from lack of food (Pg26); Dehydration and Altitude Sickness (refer below) are common in endurance type activities. These conditions share similar signs & symptoms and may occur together to create general unwellness. •Stay in the car and do not try to run - the main intensity will pass quickly. •If you think it’s hot in the car, it will be hotter outside the car. •DO NOT drive through thick smoke. •Stop vehicle on bare ground eg on a road. •Turn off the ignition and switch on headlights and hazard lights. •Wind up windows and close all vents. •Stay below the level of the windows. •Shelter from radiant heat by lying on the floor and covering yourself with woollen blankets, floor mats or clothing. •Remain in the car until the fire front has passed - even if the tyres are burning, the petrol tank is unlikely to explode. Signs & Symptoms Mild Dehydration (2% fluid loss) •Thirst •Urine dark, decreased •Weakness •Muscle cramps •Irritability •Headache •Dry mouth •Dry skin •Dizziness Sports drinks contain water, electrolytes and sugar for quick rehydration. MAKING A SPORTS DRINK 1 litre water, 1/2 tsp baking soda, 1/2 tsp table salt, 1/4 tsp potassium salt (low salt), 2 tablespoons sugar Moderate Dehydration (5% fluid loss) •Heart rate increases •Breathing rate increases •Decreased sweating •Fever •Nausea •Tingling limbs •Weight Loss •Tongue coated & thick Severe Dehydration (10% fluid loss) •Muscle spasms •Vomiting •Racing pulse •Dim vision •Painful urination •Confusion •Breathing difficulty •Seizures •Chest & Abdo pain •Unconsciousness First Aid •Reduce Fluid Loss: Rest; Keep Cool; Seek Shade & Shelter •Rehydrate: Drink water, sports drinks, eat food or salt tablet •DO NOT DRINK: caffeinated drinks or alcohol (body consumes fluids to digest them). •Record Fluid Intake/Output (Pg 83) •Moderate/ Severe Dehydration: Call (IV fluids needed) ☎ Altitude Sickness Common above 2400m (8000ft) where air pressure and oxygen concentration drops. Acute Mountain Sickness (AMS) can progress to High Altitude Pulmonary Edema (HAPE) or High Altitude Cerebral Edema (HACE), which are potentially fatal. Signs & Symptoms Acute Mountain Sickness (AMS) Headache Fatigue Dizziness Breathlessness on exertion Sleep disturbance Poor appetite, Nausea Swelling of hands, feet, face First Aid • Re-warm High Altitude Pulmonary Edema (HAPE) Fluid on the lungs Persistent dry cough Breathlessness at rest Fever • Re-hydrate • Re-sugar High Altitude Cerebral Edema (HACE) Swelling of the brain Headache Unsteady gait Uncoordinated Loss of consciousness • Re-oxygenate • Descend 72 | Remote First Aid Hygiene (See Pgs 63, 80) Hygiene is the actions or practices of personal cleanliness that protect health. In a remote situation, without hot and cold running water, proper hygiene requires more effort and planning. •Wash hands frequently with soap and water, alcohol wipes or sanitizer gel. •Place a basin with water, disinfectant and nail brush near toilet area. •DO NOT share utensils or water bottles . •Wash and dry your face, underarms, genitalia and feet daily to avoid chaffing and fungal infections. Infection Control in a Remote Area Anyone suffering from diarrhoea, infected eye / wound or influenza should be isolated as follows: •The infectious person should sleep in a tent on their own and keep their dishes, cutlery, soap and towel separate. Anyone having contact with an infectious person should: •Use protective/rubber gloves with all cases of infection, especially when cleaning up blood, vomit, stools (Pg 63), or cleaning an infected wound (Pgs 61, 62). •Wear goggles or sunglasses when attending to wounds. •Use face masks in cases of airborne infection such as influenza. •Wash and dry hands after contact with the infectious person, their clothes or belongings. Preventing Diarrhoea and Food Poisoning: •Purify drinking water (Pg 68) •Avoid touching your mouth with your hands. •Wash hands frequently and dry using a clean towel or air dry (drying is as important as washing especially if preparing food). •An infectious person should not be allowed near food preparation, serving or washing up. •All kitchen utensils must be kept scrupulously clean. •Keep flies, cockroaches, and rats off prepared food and preparation surfaces. •Use two chopping boards (and knives) - one for meat and fish and one for other purposes. •Chopping board and knife used for meat and fish must be scalded after use. •Vegetables should be washed, soaked in iodine solution and well cooked. •Salads may cause diarrhoea even after careful preparation. •Peel fruit and boil fresh milk. •All cooked food should be eaten immediately. •Avoid reheated food or reheat thoroughly to minimize the risk of food poisoning. Remote First Aid | 73 Moving a Casualty As a general rule you should avoid moving a casualty unless there is a hazard or situation you cannot remove eg fire, floods, cold, heat, fumes, rough ground, ants, snakes. Moving a casualty, especially an unconscious or spinal injured casualty, can be difficult and should be left to medical personnel who have the training and equipment necessary to protect themselves and the casualty. If moving the casualty is essential, take extreme care and use a good lifting technique. Lifting Technique (see Pg 80): • Bend your knees • Keep back straight Before moving a casualty consider: and head up • Stay balanced • Keep • Size of casualty in relation to yourself • Number of a low centre of gravity • Hold weight people helping • Type and seriousness of injuries close to your body • Work as a team • Terrain to be crossed • Distance to be covered someone must take control. • Neck stabilisation • Travel and motion sickness. If the decision to move is made, ENSURE: • Bleeding is controlled • Fractures are immobilised • Casualty is secure • Aiway is managed (if unconscious) • Casualty feels safe. • Conscious casualty sits forward and folds arms across their chest. • 1st helper bends down and places their arms under casualty’s armpits and graps wrists. • 2nd helper bends down and secures casualty’s knees. • Both helpers rise together & walk forward Fore & Aft Carry 4 Handed Seat Carry Improvised Stretchers: •Before using an improvised stretcher, test it out of casualty’s sight. •Tent poles or straight branches can be used with jackets, sacks, broad bandages or tarpaulins to make stretchers. Preventing wound infection: •In hot humid environments wounds may easily become infected. •Clean superficial wounds thoroughly with purified water or saline (salt) solution. •Apply antiseptic preparation such as iodine, betadine, savlon cream to prevent infection. •Deep, dirty wounds occurring in remote areas must be cleaned and covered but not closed, as serious infections such as tetanus and gangrene thrive in dark, moist, low oxygen environments. Medical attention must be arranged ASAP. •Recognise signs of wound infection (Pg 62). • Each helper grasps their own left wrist with their right hand. • Then each helper grasps the right wrist of the rescuer opposite with their free hand. • Both helpers lower themselves sufficiently for casualty to sit on 4 handed seat. • Casualty places her arms around helpers’ shoulders and before helpers rise to an upright position. Broad Bandage & Pole • Tie broad bandages 1) Button 2 or 3 jackets and turn them inside out, leaving the sleeves inside Jacket & Pole between poles at intervals. • Place blanket, sleeping bag or tarpaulin on top. 2) Pass poles through the sleeves Sack & Pole • Use 2 empty heavy-fabric sacks • Cut holes in the 2 corners of closed ends • Place sacks with open ends facing each other • Slide poles through holes • Overlap open ends 10 cm to provide extra strength in the middle 74 | Remote First Aid Remote First Aid | 75 Communication Radio: UHF, 27MHz, CB and VHF radios all operate by direct line of sight.

AIR RESCUE - Helicopter: Helicopter - After Landing: •Do not approach while the blades are turning unless you get thumbs up from the crew. Flare 30m •Approach and depart helicopter within the pilot’s field of vision -10 to 2 o’clock (Diagram 6). Diagram 5 - Helicopter Night Landing •Indicate your intensions to approach by giving a thumbs up to the pilot. •Keep head and shoulders bent over - move calmly and swiftly (Diagram 7). •Secure hats and other loose gear. •Do not carry anything above your head. •If blinded by dust, stop, sit down and wait for assistance - do not stumble around blindly. •On sloping ground approach from the downhill side (Diagram 7). •No smoking near aircraft. 10 O’Clock Diagram 6 2 O’Clock Diagram 7 78 | General First Aid Principles of First Aid General First Aid | 79 Communication What is First Aid? It’s the immediate care of an injured or suddenly sick casualty until more advanced care arrives. The aims of first aid are to: • Preserve life – This includes the life of rescuer, bystander and casualty. • Protect from further harm – Ensure the scene is safe and avoid harmful intervention. • Prevent condition worsening – Provide appropriate treatment. . • Promote recovery – Act quickly, provide comfort and reassurance, get help, Call Helping at an emergency may involve: • Phoning for help • Comforting casualty or family • Keeping order at an emergency scene • Administering first aid There are many ways you can help, but first you must decide to act. Reasons why people do not help: •Fear of doing something wrong •Fear of disease transmission •Uncertainty about the casualty •Nature of injury or illness (blood, vomit, burnt skin can be unpleasant) •Presence of bystanders (embarrassed to come forward or take responsibility). You may need to compose yourself before acting. Do not panic – a calm and controlled first aider gives everyone confidence. If you follow basic first aid procedures, you should deliver appropriate care, even if you don’t know what the underlying problem is. Remember, at an emergency scene, your help is needed. Getting Help: for ambulance, fire or police. If from a mobile phone fails, call ‘112’ or ‘911’. Call If you ask for ‘ambulance’, a trained communications officer will ask you the following: • What is the exact location of the incident? • What is the phone number from which you are calling? • Caller’s name • What has happened? • How many casualties? • Condition of the casualty(s) •Stay calm and respond clearly. The communications officer will provide you with first aid instructions and dispatch the ambulance and paramedics. •DO NOT hang-up until you are told to do so or the operator hangs up first. call, ensure they confirm with you that the call has been •If a bystander is making the made and that the location is exact. ☎ ☎ ☎ ☎ Legal Issues No ‘Good Samaritan’ or volunteer in Australia has ever been successfully sued for the consequences of rendering assistance to a person in need. A ‘Good Samaritan’ is a person acting in ‘good faith’ without the expectation of financial or other reward. Duty of care: In a workplace environment there is an automatic duty of care to staff and customers - a failure to act in a way that is consistent with an obligation to provide reasonable assistance, to the best of your ability, may result in negligence and possible litigation. In the community, you are under no legal obligation to provide first aid. Consent: Before providing first aid, you must first gain consent from the casualty. If the casualty refuses help, you must respect their decision. If the casualty is unresponsive or of unsound mind and therefore unable to give consent, it is assumed they would give consent if they were conscious and/ or orientated. If the casualty is a child, the parent/ guardian should be asked permission, but if no parent/guardian is present and the injury/illness is lifethreatening, immediate first aid should be given. Confidentiality: Personal information about the health of a casualty is confidential. This information includes details of medical conditions, treatment provided and the results of tests. Disclosure of personal information, without the person’s written consent is unethical and in some cases may be illegal. The role of the first aider depends on gaining and honouring the trust of casualties. Maintaining trust requires attentiveness to body language, quality of listening and finding culturally appropriate ways of communicating that are courteous and clear. It may sometimes be necessary to communicate through verbal and non-verbal communication and you may need to identify issues that may cause conflict or misunderstanding. The first aider also needs to maintain respect for privacy and dignity and pay careful attention to client consent and confidentiality. Reports While waiting for help and if time permits, make a brief written report to accompany the casualty to hospital. This will reduce time spent at the scene for ambulance crew and further assist medical and nursing staff with initial patient management. A report can be written on a spare piece of paper and should include the following: • Date, time, location of incident The back inside page • Casualty details - Name, DOB, Address. contains a ‘First Aid Report Form,’ which can be torn • Contact person for casualty - Family member, friend. out and used at a first aid • What happened - Brief description of injury or illness. incident. • First aid action taken – What you did to help the casualty. • Other health problems – Diabetes, epilepsy, asthma, heart problems, operations. • Medications/ allergies – Current tablets, medicines. • When casualty last ate or drank – Tea, coffee, water, food. • Observations of Vital Signs - Conscious state, pulse, breathing, skin state, pupils. • First aider’s name/ phone number incase medical staff need any further information. Record Keeping • In the workplace, it is important to be aware of the correct documentation and record keeping used in first aid situations • Every organisation has its own procedures and documentation so, familiarize yourself with the correct process • All documentation must be legible and accurate and must contain a description of the illness or injury and any treatment given • Thorough, accurate medical records are essential in any court case or workers compensation issue • NEVER record your opinion or judgement • Documents completed in the course of employment remain the property of the employer • Retain records for 3-7yrs • Write in pen (not pencil) • Never use correction fluid – cross out and initial any changes • Sign and date the form • Keep contents strictly confidential • Store in secure location Self-help/ Evaluation Each person reacts differently to traumatic events and in some instances strong emotions may affect wellbeing and work performance. Symptoms may appear immediately or sometimes months later after an event and may develop into chronic illness. There is no right or wrong way to feel after an event but what a person experiences is valid for that person. It is useful to identify and work through these reactions/feelings as early as possible. Speaking to an understanding friend, counselor or medical professional may be beneficial in assisting you to cope with the situation. In addition, seeking feedback from medical personnel about your first aid performance may assist with self-improvement and prepare you better for any future events. Some Reactions/ Symptoms • Crying for no apparent reason • Difficulty making decisions • Difficulty sleeping • Disbelief • Irritability • Disorientation • Apathy • Sadness • Depression • Excessive drinking or drug use • Extreme hunger or lack of appetite • Fear/anxiety about the future • Feeling powerless • Flashbacks • Headaches • Stomach problems • Heart palpitations • Muscle aches • Stiff neck 80 | General First Aid General First Aid | 81 Safe Manual Handling When lifting or moving a casualty it’s important the first aider protects him/herself from injury by using correct lifting techniques - bending the knees and using leg muscles will help protect against back injury. However, knowing your own limitations and asking for assistance if required is also important in preventing injury. In addition, learning the correct procedures for moving a casualty (eg rolling casualty into recovery position) further minimises injury to the casualty and first aider. Needle Stick Injury FIRST AID The risk of catching a serious infection (Hepatitis B, C • Squeeze blood out of injury site. • Wipe with alcohol swab. and HIV) from needle stick injury is very low. • Wash hands.

Disposable gloves will not protect against needle stick injury. Hygiene Prior to treatment: Minimise the risk of cross infection to yourself, bystanders and casualty by taking appropriate precautions: • Wash hands with soap and water, or rinse with antiseptic. • Cover cuts on your hands with a waterproof dressing before putting on gloves. • Wear disposable gloves. • Do not touch any unclean object when wearing gloves . • Use a plastic apron and eye protection. • Cover any adjacent areas likely to produce infection. During treatment: After treatment: • Use a face shield/ mask, if available when performing resuscitation. • DO NOT cough, sneeze or breath over a wound. • Avoid contact with body fluids. • DO NOT treat more than one casualty without washing hands and changing gloves. • Clean up the casualty, yourself and immediate vicinity. • Safely dispose of used dressings, bandages and disposable gloves • Wash hands thoroughly with soap and water, even if gloves were used. • Restock first aid room/ first aid kit.

Wound Dressing No. 14 1 First Aid Kits Casualty Assessment When dealing with a person who is ill or injured, you need a clear Plan of Action: 1.Start with a Primary Survey (DRSABCD), (Pg 3-5) which enables identification and management of life-threatening conditions. 2.If there are no life-threatening conditions which require immediate first aid (severe bleeding, no response) then proceed to Secondary Survey. Secondary Survey - is a systematic check of the casualty involving: • Questions • Examination • Clue Finding to help identify any problems that may have been missed. • If the casualty is unconscious, the secondary survey is conducted in the recovery position. You may need to look for external clues and ask bystanders some questions. • If the casualty is conscious start with questions followed by examination. Remember to introduce yourself, ask for consent to help and ask their name. Examination Questions •What happened?

Pressure Gauge Fluid Balance - Intake and Output Bulb 120 Systolic Fluid Intake/ Output charts are used to monitor and assess the level of hydration in a sick casualty eg with diarrhoea and vomiting. (For signs and symptoms of dehydration see Pg 71). 70 Diastolic Cuff Valve Weight: Time Measuring Blood Pressure Measuring Blood Pressure: •Explain to casualty what you are doing (if conscious). •Casualty can be sitting or lying with their arm at heart level (recovery position if unconscious). •Use the left arm unless injury or position of casualty prevents this. •Wrap cuff around bare upper arm (remove thick clothing) and secure velcro strip. •Place stethoscope earpieces in your ears and stethoscope bell in the crease of casualty’s arm (over brachial artery). •Close valve on bulb of sphygmomanometer by rotating clockwise between finger and thumb. •Inflate cuff by squeezing bulb until radial pulse is lost. •Slowly deflate cuff by rotating valve anticlockwise whilst listening with stethoscope and looking at pressure gauge. •When the cuff pressure falls to the point where blood flows through the brachial artery again, you will hear a ‘hub-dub’ sound. Look at the pressure gauge and read the number at this point. This is the systolic pressure. •When the cuff de-pressurises to the point that blood flows freely in the artery, the sound is no longer heard in the stethoscope. Look at the pressure gauge and read the number at this point. This is the diastolic pressure. •Record the systolic and diastolic pressures (eg 120/70) and note the arm used for taking the measurement. Low Blood Pressure (Hypotension): Is defined as a systolic pressure below 90 mmHg. Causes: •Reduced cardiac output due to a weakened heart (eg heart attack). •Reduced blood volume due to dehydration or massive blood loss. •Excessive dilitation of blood vessels (eg anaphylaxis, spinal cord injury). NB. A rising pulse rate and a dropping BP following trauma is suggestive of internal bleeding High Blood Pressure (Hypertension): Is defined as a repeatedly elevated blood pressure exceeding 140 over 90 mmHg ie a systolic pressure above 140 with a diastolic pressure above 90. Lifestyle is often the cause of chronic high blood pressure eg smoking, obesity, lack of exercise and diet. NB. High blood pressure and a rapid pulse is associated with acute pain (adrenaline surge) 1 cup 150ml 1 glass 240ml 1 ounce You will need: •One jug marked in milliletres (all volumes recorded in milliletres). 1 tablespoon •Two large containers (eg buckets) marked with capacity - eg one for 1 teaspoon vomit, the other for watery stool. •Fluid intake and output chart to record all measurements and remarks. 30ml 15ml 5ml Fluid Input/ Output Chart Date: Stethoscope Conversion Table INTAKE Oral * IV OUTPUT Urine Vomit Stools NOTES Blood 7am - 3pm 3pm - 11pm 11pm - 7am 24hr Totals SUM TOTAL for 24hrs -ve Fluid Balance: +ve Fluid Balance: * IV means intravenous fluid and only applies to casualties on a drip Fluids In: • Water • Juice • Tea • Soup • Ice cream • Custard • Ice cubes (melt to half their volume) Fluids Out: • Urine • Watery stools • Vomit • Blood • Excessive sweating AVPU Scale - a Measure of Responsiveness •The AVPU scale is a system for measuring a casualty’s state of responsiveness. •The AVPU system is only used to monitor vital signs in a sick or injured casualty while awaiting medical assistance (see Workplace Casualty Report at back of book). •To ascertain a response in a collapsed casualty follow DRSABCD (Pg 4). ALERT - Fully awake (may be disorientated). Casualty spontaneously opens eyes and responds to voice (may be confused). VOICE - Casualty responds when spoken to - this may be a grunt, moan, slight movement or opening of eyes. PAIN - Casualty makes a response to a painful stimulus: • Pinch casualty’s ear • Press pen (or key) onto casualty’s fingernail. UNRESPONSIVE - Casualty does not give any eye, voice or motor response to voice or pain. Core Body Temperature (See also Pgs 28-29) Core temperature readings depend on which part of the body is being measured. The sites used by a first aider to measure core body temperature include: • Under the arm (36.4 °C) • Under the tongue (36.8 °C) • In the ear (37.6 °C) A digital thermometer can be used under the tongue or armpit at any age from birth (ear thermometers not suitable for babies). A temperature reading by itself does not indicate how sick the casualty is but progressive measurements may assist medics ascertain a diagnosis/ treatment.
