Identify the basic principles of airway management Objectives (cont’d) Describe the indications for suctioning. Identify rigid and flexible suction catheters and the indications for use. Identify indications and contraindications for use of the PEAD’s. Identify the advantages and disadvantages of using PEAD’s. Objectives (cont’d) Identify those situations in which PEAD’s may be removed. Demonstrated placement of PEAD’s. Demonstrate methods of assuring and maintaining correct placement of PEAD’s. Demonstrate re-ventilation for missed placement of PEAD’s. Objectives (cont’d) Demonstrate on a manikin the proper technique for the use and maintenance of the following airway adjuncts: Nasal cannula Non-rebreather mask Bag-Valve-Mask Demonstrate sterile suctioning techniques on a manikin with a PEAD in place. Lesson 1 Respiratory Anatomy & Physiology Respiratory Anatomy & Physiology Function of the Respiratory System Removes carbon dioxide from the blood Transfers oxygen to the blood The Upper Airway A B C D E F G H Epiglottis Mandible Frontal Sinus Soft Palate Trachea Glottis Esophagus Vocal Cords The Upper Airway Other Structures Nasopharynx Oropharynx Hypopharynx Larynx Functions Functions of the Upper Airway Passageway for air Warm Filter Humidify Protection Gag Reflex Cough Speech The Lower Airway A Primary Bronchi B Hyoid Bone C Right Lung D Secondary Bronchi E Tracheal Ligament F Trachea G Larynx H Esophagus I Left Lung J Trachea Alveoli Gas Exchange Lungs Structure Lobes Pleura Physiology of Respiration Define Respiration The exchange of gases between a living organism and the environment Define Ventilation Mechanical Process that moves air in and out of the lungs Muscles of Breathing Intercostal Muscles Diaphragm Regulation of Respiration Where is the Respiratory Center Controlled? Brainstem Stretch receptors Medulla Apeustic Center (pons) Pneumotaxic center (pons) Hering-Breuer reflex Chemoreceptors CSF Blood Voluntary or Involuntary Both Humans can override body’s urge to breathe But only for so long Respiratory Cycle Inspiration Active phase Lasts 1-2 seconds Expiration Passive phase Lasts 5 seconds Lesson 2 Respiratory Volume and Management Drinking Straw Exercise Breathe through straws for 1 minute Carbon Dioxide & The Respiratory System High CO2 Low CO2 Increases respiratory rate Decreases respiratory rate Hypoxic Drive Chronic COPD patients Normal Respiratory Rates Adult Children Infants Newborns 12 – 20 / min 18 – 24 / min 22 – 36 / min 40 – 60 / min Factors Affecting Respiratory Rate Fever Depressant Drugs Anxiety Insufficient Oxygen Stimulant Drugs Sleep Respiratory Volumes Lung Capacity Tidal Volume Dead Space Alveolar Air 6000 mL of air 500 mL at rest 150 mL 350 mL Minute Volume Total air moved per minute Rate X Volume = Minute volume Important Assessment Item Factors Affecting Minute Volume Head, neck, chest injury Shock Diabetes CO2 / O2 rapid changes Maintaining the A in ABC Patient positioning Suctioning Supplemental Oxygen Mechanical Assistance Pulse Oximetry Measures amount of oxygen in the blood. Gives percent of hemoglobin saturated Tool only, do not rely on totally Why? Normal Values 95% - 100% Normal 90% - 95% - Mild – Normal for COPD < 90 % Moderate – High Flow Oxygen End-Tidal CO2 Detection Measured Colorimetric and Digital Tool to aid in determining correct placement Lesson 3 Assessing Respiratory Problems Patient Assessment General Patient Assessment Primary Survey LOC ABC’s Speech Pattern Obvious Respiratory Noise Patient Position General Assessment (cont’d) Secondary Assessment SAMPLE history Chief Complaint Pertinent Negatives Chest Pain (pleuritic vs cardiac) Cough History Edema Vitals Respiratory Assessment Confusion, Agitation, Orientation Cyanosis (late sign) Diaphoresis Retractions Accessory Muscle Use Jugular Venous Distention Nasal Flaring / Pursed Lip Breathing Palpation Skin Turgor Color Temperature Diaphoresis Pulse Rate Rhythm Quality Chest Wall Pain Tracheal Deviation Assessing Lung Sounds Methods Hand Out Lung Sounds Normal Wheezes Rales (Crackles) Stridor Rhonchi Pleural Rub Listen on every patient End of Expiration End of Inspiration During both phases Expiration End of Inspiration Respiratory Diseases COPD Asthma Pneumonia Pulmonary Edema Pulmonary Embolus Trauma COPD Chronic Obstructive Pulmonary Disease Pink Puffers and Blue Bloaters Frequently on Home oxygen Assessment Typical Lung Sounds Common Medications May or May not be Hypoxic Drive Asthma Asthma Bronchiole Constriction & Mucous Production Lung Sounds Wheezes Diminished None Usually Diagnosed Pneumonia Pneumonia Fever Productive Cough Colored Sputum General Illness Elderly & Pediatric most at risk Lung Sounds Rhonchi, Rales, Wheezes Pulmonary Edema Pulmonary Edema Congestive Heart Failure Acute – Flash Pulmonary Edema Chronic – Heart Failure Medications Orthopnea, PND Lung Sounds Keep them upright with legs dangling Pulmonary Embolus Pulmonary Embolus Lung Sounds History Surgery Bed Confined Long trip Rapid Transport & High Flow Oxygen Trauma Trauma Maintain spinal control Airway Management High Flow Oxygen Rapid Transport Seal Chest Wounds Stabilize Impaled Objects Lesson 4 Respiratory/Cardiac Arrest Basic Airway Management Respiratory & Cardiac Arrest Assessing the Patient First Steps of CPR Annie, Annie You Okay? Other Signs and Symptoms Unconsciousness Cardiac Seizure Agonal respirations or apnea Cyanosis, Ashen, Mottled No signs of spontaneous respiration or circulation No Pulse Combitube When to Use the Combitube CPR Remember to do CPR! Attach AED! Respiratory Arrest Agonal Respirations without intact gag reflex Respiratory Arrest leads to Cardiac Arrest Airway Management – The Basics Manual Maneuvers Chin Lift Jaw Lift Jaw Thrust Head Tilt – Chin Lift Modified Jaw thrust Airway Management – The Basics Mechanical Airways NPA’s OPA’s Description Advantages Disadvantages Indications Contraindications Methods of Insertion Airway Management – The Basics Ventilation Mouth to Mask BVM Description Advantages Disadvantages Indications Contraindications Methods of Use Evaluation of Effectiveness How do I know I am ventilating?
