Some Aspects of Cerebrovascular Resistance in Raised Intracranial Pressure: An Experimental Study
Observations on pressure waves occurring in the course of pathological states in man have indicated that, during increased intracranial pressure, intracranial pulsation is markedly increased (1,2,3). It seems probable, therefore, that during rising intracranial pressure, some abnormality of cerebrovascular resistance is present. This is further implied by the demonstration is previous experiments (4,5) that cerebral blood flow is maintained up to a point despite rising intracranial pressure. The present experiments were designed to determine the behaviour of the cerebrovascular resistance during experimentally raised intracranial pressure in the baboon.
