Complex Care of the Neuro Pt Flashcards
Blood Glucose
Sole energy source of the brain
Cerebral glucose less than 70 s/s
CONFUSION
Cerebral glucose less than 20 s/s
Damage
Increased MAP causes cerebral
consriction
Decrease MAP causes cerebral
Dilation
Elevated CO2 causes cerebral
vasodilation
Decrease 02 (hypoxia) causes cerebral
Vasodilation
Cerebral Perfusion Pressure
CPP= MAP - ICP
Normal CPP 60 - 100
Cerebral circulation
Cerebral veina - venous sinuses - internal jugular - superior VC
Co2 is a
VASODILATOR
Hypotension causes ? in cerebral circularion
Decrease cerebral Blood flow
Hypertension causes ? in cerebral circulation
ICP
Normal ICP
0 - 15 mmHg
Increased ICP
Greater than 20 mmHg for more than 5 minutes
ICP = MAP cerebral blood flow ceases. WHen does ICP = MAP
Hypotension, hypovolemia
