title: [The role of the cerebral cortex venules in normal oxygen transport and in normobaric hyperoxia].
abstract: Mathematical processing revealed no statistically significant dependence of the oxygen tension distribution (pO2) over the wall of the vessel under study upon its diameter. The data obtained showed that, in hyperoxemia, oxygen diffusion from the blood to tissues occurs through the walls of the radial venules. In case the distance between arteriole and venule is less than 100 mcm, a diffuse shunt is possible.
