ABSTRACT:
A method and apparatus is disclosed for noninvasive monitoring of the intracranial pressure of mammals. The method preferably consists of occluding the jugular vein at a selected location so as to interrupt the flow of blood temporarily and then determining the rate of change of blood flow within the jugular vein upstream of such location over a predetermined period of time following its occlusion. Means controlled by the operation of a computer may be utilized for automatically occluding the jugular and for inducing detectable electrical signals representative of the flow of blood within the jugular.
