<prompt> Cerebral perfusion pressure is -Aerial pressure minus peripheral venous pressureVenous pressure minus aerial pressureAerial pressure minus intracranial pressureAerial pressure x venous pressure  <response>: Ans. is c i.e., Aerial pressure minus intracranial pressureRef Principles of medical physiology p. 719.Cerebral perfusion Pressure: is the difference between mean aerial pressure MAP and intracranial pressure.ICP or central venous pressure CVP whichever is greater. CPP is normally 80-100 mm Hg.
