The Brain
•
•
•
•
•
A complex organ that weighs approximately 3 pounds
Makes up 2% of our body weight
The cerebrum makes up the majority of the brain
We are all born with the same number of brain cells
Personal experiences, education, and social environment shape the
person we are
5
The Brain
• Divided into 2 hemispheres –
right and left brains
• Strongly symmetrical
• Left brain controls all muscles
on right side of body
• Right brain controls all muscles
on left side of body
6
The Brain
• Left brain
• Has region of speech and language
• Broca’s area (expressive aphasia) & Wernicke’s areas (receptive aphasia)
• Associated with mathematical calculations and fact retrieval
• Right brain
• Role in visual and auditory processing, spatial skills, and artistic ability
• Spatial skills – to understand problems with physical spaces, shapes, forms
7
Regions of the
Brain
8
Consciousness
• Normal consciousness requires arousal and cognition
• Ability to think, understand, learn, and remember
• Display of orientation, judgment, and memory
• Think of the questions we ask patients testing these areas
• Person, place, time, and event
• Arousal requires an intact and functioning brainstem
9
What is Altered Mental Status?
Altered behavior
Confusion
Change in higher cerebral
Change in attention
Change in awareness
Change in judgment
function
Change in memory
10
Obtaining a Baseline
• Determine when patient last seen normal
• Evaluate for allergies and current medications
• Inquire regarding recent hospitalizations, infection, trauma,
psychiatric illness
• Check environment for bottles (medications, alcohol, poisonings)
• Family extremely helpful to indicate subtle changes noted
11
Evidence of Changes in Brain Function
• Confusion
• Amnesia
• Loss of alertness
• Loss of orientation
• Person, place, time, event
• Defects in
judgment/thought
• Poor regulation of emotions
• Disruption in perception,
psychomotor skills, behavior
12
Content of Thought and Speech
Evaluation
• Can patient stay focused?
• Is their speech tangential (abruptly moving off topic)?
• Is patient oriented?
• Is patient concerned and focused on the issue?
• Are they asking repetitive questions?
13
“Alert & Oriented”
• What is this reference to?
• A & O x3 or A & O x4???
• Depending on what you test:
 x1 - Alert & oriented to person – their name
 x2 - Alert & oriented to place – do they recognize where they are
 x3 - Alert & oriented to time – time / day / date / season (any is reasonable)
 x4 - Alert & oriented to event – what just happened or what is happening
14
Components of Field Neurological
Assessment
• Level of alertness – AVPU and GCS scales
• Ability to keep person awake
• 12 cranial nerves (CN)
• CN 3 (oculomotor nerve) checked in the field – pupillary response
• Bilateral motor and sensory responses
• Gait – not consistently able to observe in the field
15
Neurological Assessment - AVPU
• An assessment scale not as detailed as GCS
• Can be performed very quickly
• Provides global picture of level of responsiveness
• Most important is monitoring for changes in a response
16
AVPU
• A – alert
• Not necessarily oriented; just awake
• V – responds to verbal commands
• Difficult to distinguish if patient responded to voice or touch as they are often done
simultaneously in the field
• P – responds to pain or tactile stimulation
• U – unresponsive, flaccid, no response at all
17
Glasgow Coma Scale (GCS)
• Assesses overall level of arousal
• Originated in Glasgow, Scotland
• A tool originally designed to predict prognosis in traumatic brain injured
patients
• Used to diagnose, provide outcome, and evaluate progression of disease
• Change in 2 or more points represents significant change in patients
level of consciousness
18
GCS
• Evaluate BEST RESPONSE to 3 components:
best eye opening, verbal response, and motor response
• Assign a score of 3 to 15
• The higher the score the more favorable the outcome
• Not just useful in traumatic head injury
• 13 - 15 usually indicate minor head trauma
• 9 – 12 usually indicate moderate head trauma
19
GCS – Eye Opening
• Need to approach patient and attempt to illicit eye opening response to verbal
stimuli prior to making physical contact with the patient
• Not always easy or in the best interest of the patient
• May need to apply manual c-spine control as soon as patient contact made
•
•
•
•
4 – eyes open spontaneously
3 – eyes open to command spoken or shouted
2 – eyes open after painful/noxious/tactile stimuli applied
1 – no eye response at all
20
GCS – Verbal Response
• 5 – oriented to person, place, time, event
• 4 – confused; not oriented to person, place, time, and/or event
• 3 – Inappropriate words – not able to speak in sentences; uses random
words; swearing is common
• 2 – Incomprehensible sounds – moaning and groaning; no distinguishable
words heard
• 1 – not making any verbal sounds
21
GCS – Motor Response
• 6 – obeys commands
• 5 – Purposeful movement – generally able to cross center of body; reaches
for noxious stimuli to remove it (i.e.: IV, B/P cuff, c-collar, your hands)
• 4 – Withdraws to pain – pulls arm/shoulder into body (adduction)
• 3 – Abnormal flexion – arm/shoulder abducted, extremity bends/flexes
• 2 – Abnormal extension – extremities straighten and rotate, back generally
arches
• 1- no response to all; flaccid
22
Potential Causes Altered Mental Status
AEIOU - TIPS
• A – Alcohol
• E – Endocrine, encephalopathy,
electrolytes
• I – Insulin (hypoglycemia)
• O – O2 (hypoxia), opiates
• U – uremia (kidney disease)
•
•
•
•
T – Toxins, temperature, trauma
I – Infection
P – Psychiatric, porphyria
S – stroke, shock, subarachnoid
hemorrhage, space-occupying
lesion (i.e.: tumor)
23
Potential Causes Altered Mental Status
SMASHED
• S – substrates (glucose, thiamine
deficiency), sepsis
• M – meningitis
• A – Alcohol, accident
• S – Seizure, stimulants, hallucinogens,
• E – electrolytes, encephalopathy
• D – drugs (intoxication/withdrawal),
illicit drugs, CO poisoning, steroids,
salicylates
anticholinergics
• H – Hyper/hypo (B/P, thyroid, temp,
hypercarbia, hypoxia)
24
Stroke
• Injury or death to brain tissue
• Usually from an interruption in cerebral blood flow
• Tissue deprived of oxygen and glucose
• 2 components brain cells rely on to function
• 3rd leading cause of death and disability
• Can strike any age
• Increased risk with history of atherosclerosis, heart disease, or hypertension
25
Occlusive Strokes
85% Incidence
• Cerebral artery blocked by clot or other foreign matter
• Ischemia  infarction
• Embolic stroke – usually occur suddenly
• A mass, generally a clot
• Often a thromboemboli traveling from diseased vessels or from chambers in
heart
• Thrombotic stroke – usually develop gradually
• Clot developed in and obstructs cerebral artery usually related to
atherosclerosis
26
Hemorrhagic Strokes
15% Incidence
• Usually bleeding within brain (intracerebral)
or space around outer surface of brain
(subarachnoid)
• Onset marked with sudden, severe headache
• Often related to history hypertension or congenital abnormalities
in blood vessels
27
Risk Factors for Stroke
 Hypertension
 Diabetes
 Abnormal blood lipid levels (elevated cholesterol)
 Oral contraceptive use
 Sickle cell disease
 Some cardiac dysrhythmias (i.e.: atrial fibrillation)
28
Assessment of the Patient With A Possible
Acute Stroke
• Onset of signs or symptoms or last known normal with exact time
• Blood glucose level
• Cincinnati Stroke Scale
• An abnormal finding in any one parameter associated with 72%
probability of stroke
 Facial droop
 Arm drift
 Change in speech
29
Acute Stroke Assessment cont’d
• Medication history of anticoagulant use
• Coumadin - Warfarin
• Xarelto - Rivaroxaban
• Pradaxa - Dabigatran
• Eliquis – Apixaban
• Lovenox – Enoxaparin
• History of antiplatelet use less of concern but still helpful to recognize
• Aspirin and Plavix - Clopidogrel
30
Motor and Sensory
Assessment
• Noting that responses
generated from different areas
of the brain, evaluator can
predict area of infarct by
noting the deficit
• Important to document
specific results of assessments
performed
31
Region X SOP – Stroke/Brain Attack
• RMC
• Determine time of onset / last known normal
• Obtain and record blood sugar level
• Intervene if <60
• Perform Cincinnati Stroke Scale
• Watch for rapid neurological deterioration
• Consider drug assisted intubation to protect airway if necessary
32
Rapid Neurological Deterioration
• Assess patient for changes indicating a worsening of
condition
Unequal pupils
Extensor posturing
Lateralizing signs
• A function attributed to one side of the brain
• Evaluate for deficits from patient’s normal or baseline
33
Treatment Rapid Neurological
Deterioration
• Brain reliant on adequate supply of oxygen and glucose to function
• Need to provide oxygenated blood
• Need to avoid blowing off too much carbon dioxide to prevent
potential vasoconstriction that would limit brain blood flow
• Ventilate adults 1 breath every 3 seconds via BVM (20 bpm)
• Ventilate children 1 breath every 2 seconds via BVM (30 bpm)
• Ventilate infants 1 breath every 1.7 seconds via BVM (35 bpm)
34
Excited Delirium (ExDS)
• Sudden, unexplained onset with rapid progression
Delirium – fundamental manifestation
Agitation
Aggression
Acute distress
Unusual physical strength
Acidosis – prominent role in cardiovascular collapse; usually leads to
brady-asystole or PEA
35
Excited Delirium (ExDS)
• Exact cause uncertain but felt to have multiple etiologies
• No “test” exists for diagnosis
• Need to differentiate from bad behavior, drunken behavior, and excited
delirium (ExDS)
• Hallmark
 Profuse sweating
 High body temperature (105.20F (40.70C) common on autopsy
 Delusional behavior
36
Excited Delirium - ExDS
• Increased risk of death with physiologic stress
• Immediate sedation decreases risk of death
• Stressful encounter increases chemical imbalance in brain
• Process progresses rapidly
• Most patients that die exhibit severe aggression and are non-compliant to
requests to halt their behavior
• Most patients that die found with evidence of trying to cool down
• Disrobed, empty ice trays in the environment
37
Excited Delirium – ExDS
and Chronic Cocaine Abuse
• Suspected to be co-existing risk factor causing death
• Contributes to development of coronary artery disease
• Acts as potent adrenergic agonist leading to chronic
catecholamine toxicity
• Hypertrophy
• Microangiopathy
• Myocardial fibrosis
38
Excited Delirium – ExDS
CNS Dysfunction
• Central nervous system (CNS) dysfunction of dopamine signaling with
aberrant dopamine processing blamed for clinical presentation
• Mimics of ExDS
Hypoglycemia – rule out by obtaining blood sugar
Heat stroke
Serotonin syndrome and neuroleptic malignant syndrome – but no
aggressive violent behavior
Psychiatric issues
39

40
Excited Delirium (ExDS)Treatment
• Aggressive chemical sedation required
• Treatment is concurrent with evaluation for other precipitating causes or
additional pathology
• Physical struggle increases the catecholamine surge leading to metabolic
acidosis and increasing risk of death
• Most patients that die are non-compliant and exhibit severe aggression
• Need to minimize time spent struggling while safely achieving physical
control
41
Region X SOP Field Interventions
Behavioral Emergencies
• Personal, personnel, and scene safety
• Utilize law enforcement support
• Must have prior dialogue to determine how these 2 agencies
will best work together in this potentially violent situation

• OR: Valium 10 mg IM
44
Benzodiazepines
®
®
Versed and Valium
• Sedative agents
• Relatively short acting - Versed® shorter than Valium® but more potent
• Caution
• Relatively slow onset (Versed® IN 3 – 5 minutes)
• Unpredictable action if not IVP
• Need for repeated dosing
• Potential for respiratory depression – support ventilations via BVM if
necessary
45
Medication Via Intranasal (IN) Route
• IN route medications do not pass through the gut; dosing is not diminished
• Med absorbed directly into cerebral spinal fluid via a nose brain pathway
• May cause a burning sensation for 30-45 seconds after delivery
• Ideal volume 0.5 ml per nares; max 1 ml per nares
• More volume would run out nose
• Insert wedge into nostril
• Aim to same side ear and depress plunger to create mist

68
FlowSafe II CPAP
Continuous Positive Airway Pressure
• Goal: to maintain open airways
• CPAP works by keeping airways from collapsing closed during exhalation
• Takes lots of energy to reopen closed airways
• Outcome
• Improved pulmonary air exchange
• Increase in intrathoracic pressure that reduces preload and afterload
•  preload – less blood returning to the heart
•  afterload – less vascular resistance heart has to pump against
69
CPAP
• Continuous airway pressures delivered throughout respiratory cycle
• CPAP is to be delivered simultaneously with medications
• CPAP begins to work and bridges gap waiting for medications to work
• Nitroglycerin is to be administered after patient assessment and as CPAP is
being set up
• Continue to deliver Nitroglycerin during CPAP treatment
• An effective, predictable, rapid acting method to reduce preload
70
FlowSafe II CPAP
• Connect oxygen tubing nipple to gas source
• Secure mask snugly to patient’s face
• Adjust flowmeter to CPAP of 10 (13 – 14 liters per minute)
• Note ranges provided on yellow tag on O2 tubing
71
FlowSafe II CPAP
• Patient should respond to treatment within minutes
• Patient needs encouragement and support especially first few minutes of mask use
• If needed for wheezing, can add in-line nebulizer treatment
72
Case Review
• Read the following cases
• Discuss important aspects of assessment related to the
presentation
• Determine your working diagnosis
• Discuss treatment/interventions required
73
Case Review #1
• EMS is called for a patient who is acting bizarre and running
through the streets
• While responding, you verify police have been dispatched
• Upon arrival, you note approximately 5 police officers wrestling
with a male subject
• What is your impression?
• Consider behavioral emergencies, especially excited delirium
• Consider other causes of altered mental status
74
Case Review #1
• After scene safety, what is the most important intervention to
consider for this patient?
• Sedation
• What are you considering administering?
• Versed 2 mg
• May repeat every 2 minutes to max of 10 mg
• What route would be safest and why?
• IN – avoids risk of needle exposure
75
Case Review #1
Important note:
• Delay in administering sedation increases risk of death for patient
• Tough call: need to get patient held down/manually restrained, for EMS to
get close enough to perform quick essential assessment and deliver sedation
• Then EMS moves out and lets police take over to continue to restrain patient
• Remember: this patient will not obey command, cannot be reasoned with
76
Case Review #2
•
•
•
•
•
•
35 year old male presented with weakness to left arm and slurred speech
Co-workers felt initially that he was “drunk”
Upon your arrival patient is sitting in chair leaning to the side
Eyes open, following your movement in the room
Attempts to follow commands
Speech is garbled; becoming agitated that you cannot understand him
77
Case Review #2
• What is included in your assessment?
Time last known normal
Typical vital signs, pulse oximetry, AVPU/GCS
Blood glucose level
Cincinnati Stroke Scale
78
Case Review #2
• Why is the speech unintelligible?
• Different functions arise from different areas of the brain
• Deficits can point to area of brain most likely affected
79
Case Review #2
• Why is blood sugar level necessary if patient is alert and
oriented presenting with a stroke?
• Required by AHA/ASA
• American Heart Association/American Stroke Association
• Best practice related to assessing the potential stroke patient
80
Case Review #3
•
•
•
•
EMS responds to a “fight” in progress between police and a subject
Patient reportedly naked running through the streets yelling/screaming
Upon your arrival police are attempting to mechanically restrain patient
As you walk up to the scene, you no longer hear the patient screaming or
yelling
• You notice the patient’s head rolling to the side with eyes closed
• Patient appears unconscious
• What are you going to do???
81
Case Review #3
• As quickly as possible, evaluate the patient
• Patient is apneic and pulseless
• Now what do you do?
• Begin CPR with compressions
• Get the monitor on and interpret the rhythm as soon as possible
What do you do as soon as you see a rhythm?
82
Check for a pulse; if no pulse, begin CPR
Case Review #3
• What is the rhythm and what do you do?
• PEA
• CPR 30:2 ratio (1 and 2 man CPR)
• Search for treatable causes – the H’s and T’s
• Fluid challenge 200 ml increments
• Assess lung sounds first
• Epinephrine 1:10,000 1 mg IVP/IO – repeat every 3 – 5 minutes as
needed
83
Case Review #3
• What are the most likely treatable causes to search for and
treat for this patient?
• H – hypovolemia – provide fluid challenges if lungs are clear
• H – hypoxia – ventilate with supplemental oxygen
• H+ ion - Acidosis – ventilate to get rid of the acid CO2
• Toxins – if ExDS suspected, then cocaine abuse is most likely
84
Case Review #3
• Would treatment be any different if the initial presenting
rhythm is asystole?
• No
• Treatment is the same for PEA and asystole
• PEA is treated the same regardless of the rate of the
presenting rhythm
• But, check for pulses every 2 minute pause in setting of PEA
85
Case Review #4
• EMS responds to a work environment for a 64 year old with
complaints of left upper extremity numbness
