What is cerebral perfusion pressure?

Blood flow to the brain is called cerebral perfusion pressure. Blood pressure and intracranial pressure affect the cerebral perfusion pressure. If the blood pressure is low and/or the intracranial pressure is high, the blood flow to the brain may be limited. This causes decreased cerebral perfusion pressure.
