Which of the following is a normal range for cerebral perfusion pressure (CPP)?

Cerebral perfusion pressure (CPP) is a vital measure in evaluating the blood flow to the brain, which is essential for maintaining adequate cerebral function. The normal range for CPP is generally accepted to be between 60 and 100 mmHg. This range is important because CPP represents the pressure gradient driving blood flow to the brain, ensuring that it receives the oxygen and nutrients necessary for metabolism.

When CPP falls below this range, there is a risk of cerebral ischemia, where the brain tissue may not receive sufficient blood flow, potentially leading to neurological deficits or injury. Conversely, excessively high CPP may indicate increased intracranial pressure or other pathological conditions that can be detrimental to cerebral health.

Understanding this normal range is critical for clinicians managing patients with conditions impacting intracranial pressure or cerebral circulation, ensuring appropriate interventions are taken to maintain adequate perfusion and prevent complications.
