Abstract
Peripheral vasoconstriction during simulated diving is a potential mechanism for oxygen conservation and protection against hypoxia. These experiments were done to determine whether peripheral vasoconstriction occurs in man in response to simulated diving during hypoxia, and whether there is evidence of oxygen conservation. Measurements were made of hand and forearm blood flow and of arterial blood pressure during immersion of the face in water while breathing air and 107” oxygen. Peripheral blood flow decreased during facial immersion while breathing air or 10 “X / oxygen, providing a potential oxygen-conserving mechanism. The decreased blood flow was not associated with a detectable decrease in oxygen consumption. The peripheral vasoconstriction may nevertheless have protective value during hypoxia in shifting blood flow away from the periphery to more hypoxia-sensitive organs
