Q
What is normal ICP?
A
3
Q
What is CBF determined by?
A
CBF = CPP/CVR
where CPP = MAP-ICP
therefore CBF = (MAP-ICP)/CVR
4
Q
Describe passage of common substance types across blood brain barrier.
A
- Glucose and AAs cross slowly
- Lipophilics (i.e. non polar) cross fast

Q
What is the best index to monitor progress and predict outcome of acute intracranial process?
A
Drop in GCS
