AVPU -A - Alert
-V - Responsive to verbal stimuli
-P - Responsive to painful stimuli
-U - Unresponsive
Glasgow Coma Scale - 3 -Eye opening
components -Motor responses
-Verbal responses
Glasgow Coma Scale - what do the -Maximum: 15 - fully responsive
scores mean? -8: comatose
-Minimum: 3 - severe impairment, possibly brain
death
Pupil response - Assessment -Shine pen light in one eye at a time
-Observe size, shape, and reactivity
,Pupil response - Normal response -PERRLA (Pupils Equal, Round, Reactive to Light,
Accommodation)
-Pupils are of equal size and round at baseline
-Both pupils constrict rapidly and equally with light
(consensual response)
-Pupils constrict when gaze shifts from distant to
near object
Doll's eyes movement -If brain stem is intact, the eyes should move in the
opposite direction of head rotation (e.g. head turns
left, eyes go right)
Motor response - Assessment -Purposeful movement in response to commands
(e.g. squeeze my hand, raise your arm)
-Observe for asymmetry in movement and strength
-Any response to noxious/painful stimuli (e.g. trying
to brush away your hand, decorticate, decerebrate)
-Deep tendon reflexes
-Coordination (e.g. finger-nose-finger, walk in a
straight line, drift)
-Sensation?
Motor response - Normal response -Obeys command
-Purposeful movement
Motor response - Manifestations of -Decreased - brush away noxious
altered LOC (annoying/painful) stimuli
-Decreased further - withdraw from or grimace at
noxious stimuli
-Eventually - flaccidity; no response to noxious
stimuli
, Examples of central stimulation tests -Trapezius pinch
(assessing for brain function) -Sternal rub
-Orbital pressure
Examples of peripheral stimulation -Nail bed pressure
tests (assessing for spinal cord
function)
What common causes of altered -Alcohol
LOC can impact (or cloud) your -Epilepsy
neuro assessment? (hint: AEIOU -Insulin (hypoglycemia)
TIPSS) -Opiates
-Uremia (uremic encephalopathy)
-Tumor
-Injury (TBI)
-Psychological (e.g. psychosis, depression)
-Stroke
-Sepsis
-Others
What are some tests you would do -Blood glucose
to rule out various causes of altered -Electrolytes
LOC or coma? -ABG
-Ammonia
Cushing's Triad 1) Elevated SBP, widening pulse pressure
2) Bradycardia
3) Irregular respirations (e.g. Cheyne-Stokes)
Primary injury -Initial, mechanical injury to neurons from traumatic
event
-Often causes irreversible damage
-E.g. contusion, concussion, hemorrhage, diffuse
axonal injury
