Cerebral perfusion pressure is
High-Yield Explanation
Cerebral perfusion pressure (CPP), is the difference between mean aerial pressure (MAP) and intracranial pressure (ICP): CPP (75-105 mmHg) = MAP (90-110 mmHg) - ICP (5-15 mmHg).Normal cerebral blood flow (CBF) is about 55 mL/minute for every 100 g of brain tissue. Ischaemia results when this rate drops below 20 mL/min,Bailey and love 26e pg: 310
