cerebral perfusion pressure

Cerebral perfusion pressure (CPP) is the measure of the blood flow reaching the brain tissues, which is essential for delivering oxygen and nutrients. It’s calculated by subtracting the pressure inside the brain's veins and skull (intracranial pressure) from the blood pressure in the arteries supplying the brain. Maintaining an adequate CPP is crucial because too low a pressure can lead to insufficient blood flow, risking brain damage, while too high can cause increased pressure inside the skull. Healthcare providers monitor CPP to ensure the brain gets enough blood and to prevent or manage brain injuries effectively.
