Abstract
The present invention provides a method of non-invasively measuring cerebral perfusion pressure from a composite of individual blood flow velocities in the left and right side middle cerebral arteries. The velocity measurements are preferably obtained using Doppler ultrasonography and the left and right measurements are preferably averaged.
