What MAP is targeted for adequate cerebral perfusion in traumatic brain injury patients?

Explanation:
Cerebral perfusion depends on cerebral perfusion pressure, which is MAP minus intracranial pressure (CPP = MAP − ICP). After traumatic brain injury, ICP can rise, so you aim to keep CPP above a level that prevents ischemia. In practice, targeting a mean arterial pressure around 70 mmHg helps maintain CPP in the protective range (roughly 60–70 mmHg CPP for many patients) without pushing MAP higher than necessary. If ICP is particularly high, clinicians may need to raise MAP further to keep CPP adequate, but the common target is about 70 mmHg.
