Cerebral Perfusion Pressure (CPP)

Cerebral Perfusion Pressure (CPP) refers to the pressure needed to ensure blood flow to the brain. It is calculated by subtracting the pressure in the brain's veins (venous pressure) from the pressure of blood in the arteries (arterial pressure). Adequate CPP is vital for brain health, as it ensures that oxygen and nutrients reach brain cells. If CPP is too low, brain functions can be impaired, leading to serious conditions. Conversely, excessive CPP can cause swelling or bleeding. Maintaining an optimal CPP is crucial in treating brain injuries and other conditions affecting cerebral circulation.
