Coronary perfusion pressure - Wikipedia

WebArterial pressure measured at the zero venous pressure level is arithmetically equivalent to cerebral perfusion pressure (CPP = MAP – 0). Skull base approximates zero venous pressure level when CVP – ρgh < 0, because jugular veins are exposed to the atmospheric pressure upon exiting the scull.
