intracranial pressure - Medical Dictionary

WebCerebral perfusion pressure, or CPP, is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion).It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), and too much could raise intracranial pressure (ICP). WebWhen we talk about blood flow, what we’re really talking about is cerebral perfusion pressure, or CPP. To calculate your CPP, you’re going to use this super simple formula: CPP = MAP – ICP. So as your ICP goes up, your CPP goes down. We typically like CPP to be above 60, and ICP below 20. sharice cannady
