Summary
Experiments were performed on cats under urethane anesthesia. The effect of increased or decreased oxygen supply on oxygen tension were investigated. It was found that in hypoxia, changes in the tissue oxygen tension follow the degree of oxygen saturation of arterial blood, and are delayed slightly in time compared to the latter. The higher the oxygen concentration in the inspired air, the greater is the increase of the oxygen tension in the tissues.
The latent period for the change in oxygen tension is shorter in the brain than in skeletal muscle.
