measures level of consciousness.
is the most sensitive indicator of change in neuro status - Glasgow Coma Scale
- Glasgow Coma Scale measure what three areas?
-
1. eyes open
2. best verbal response
3. best motor response -
with the glasgow coma scale you can score between 3-15.
a score of 8 or better means what? -

High score of 8 or better you have a good prognosis
score of 3-4 = high mortality
score of 3-7 = coma - ____________= an increase in intracranial bulk due to blood, CSF, or swelling of brain tissue or tumors.
-
ICP
increased intracranial pressure - Increased pressure impedes cerebral circulation, absorption of _____, and function of nerve cells
