Calculate CPP given BP 106/52 and ICP 14.

Explanation:
Cerebral perfusion pressure (CPP) is the pressure that drives blood flow to the brain, calculated as mean arterial pressure (MAP) minus intracranial pressure (ICP). First estimate MAP from the blood pressure 106/52. Using MAP ≈ (SBP + 2×DBP)/3, MAP ≈ (106 + 2×52)/3 = (106 + 104)/3 = 210/3 = 70 mmHg. Then CPP = MAP − ICP = 70 − 14 = 56 mmHg. So the value is 56 mmHg. Typically, CPP targets are around 60–70 mmHg, so this is slightly below the ideal range.
