The Effect of Brain Edema on the Microcirculation

Conference paper

Abstract

Although a great deal of effort has been expended on the measurement of cerebral blood flow, it is not an active process in its own right, but only the passive movement of blood in tubes down hydrostatic pressure gradients. Similarly, the movement of water in the brain between various compartments is purely passive, following both hydrostatic and osmotic pressure gradients. The amount of water and the rate at which it moves down these gradients depend on the size of the gradient and on the physical characteristics of the tissues and their membranes, i.e., tissue compliance and membrane permeability [1].
