-does not meet brain death criteria

1 vegetative state 2 What percent of body weight is the brain
3 consciousness continuum 4 benzo overdose treatment
Don't know?
Terms in this set (189)
What percent of body weight is the brain 2%
What percent of CO does the brain take per 15%
minute
What percent of oxygen does the brain use 20%
The brain does not store what oxygen or nutrition
the brain does not recover what nervous tissue injury
how long can the brain survive without 10 seconds
oxygen
, when does apoptosis start in the brain 4-6 minutes
Neuroplasticity rest of brain will try to adapt to take care of injured site
consciousness depends on what cerebral cortex function and reticular formation
RAS - brain stems "reticular activating system"
-wakefulness
-activates higher enters of cerebral cortex
low RAS activity leads to -lower awareness/wakefulness (sleep)
Low RAS activity due to pathology -decreased perfusion- altered metabolic state-altered
consciousness
consciousness continuum conscious to unconscious
sleep is a state of what unconsciousness
different between coma and sleep wakefulness from stimuli
loss of oxygen will cause anaerobic respiration and lactic acid will build up leading to
injury and inflammation
eye opening response GCS 4 spontaneously
3 to speech
2 to pain
1 no response
verbal response GCS 5 - oriented
4 - confused
3 - inappropriate words
2 - incomprehensible sounds
1 - none
motor response GCS 6-obeys commands
5-localizes pain
4-withdraws from pain
3-abnormal flexion
2-abnormal extension
1-none
hypoxia deficient delivery of oxygen to the tissue
-leads to decreased oxygen within a tissue (ischemia)
-often result of hypoxemia (low blood oxygen)
brain injury sequelae ischemia, cerebral edema, metabolic acidosis, ICP
ischemic brain injury lack of oxygen in brain tissue
what occurs as a result of ischemia in the compensatory vasodilation
CNS
vasodilation creates what edema- brain begins to be crushed by soul (ICP)
why does metabolic acidosis occur from lack of oxygen leads to anaerobic metabolism and a build up
brain injury of lactic acid
