Abstract
A method and apparatus are provided for measuring intracranial pressure. The method includes the steps of measuring arterial inflow, venous outflow and cranial spinal fluid flow and calculating an intracranial volume change from the measured arterial inflow, venous outflow and cranial spinal fluid flow. The method also includes the steps of calculating a pressure gradient of spinal fluid flow from the measured cranial spinal fluid flow and calculating a pressure change per unit volume change based upon the calculated intracranial volume change and cranial pressure gradient.
