The cerebral perfusion pressure (CPP) refers to the net vascular pressure gradient required for maintenance of cerebral perfusion. The normal range for CPP is 70-85 mmHg.
It is essential to maintain an optimal CPP to ensure a sufficient supply of blood and oxygen to fulfill the metabolic requirements of the brain.
A poor CPP increases the risk of cerebral ischemia. Traumatic brain injuries are the most common cause of a reduced CPP.
Formula used:
CPP = MAP - ICP
OR
CPP = MAP - CVP

User need to enter the above mentioned values, which are used in the formulas given below
CPP = MAP - ICP
OR
CPP = MAP - CVP
