Depiction of the highest oxygen-consuming and perfused organs in the body under resting conditions. Depiction of the highest oxygen-consuming and perfused organs in the body under resting conditions. The deleterious effects of hyperoxia on the viscera are markedly influenced by metabolic rate and perfusion. Although the kidneys, at first glance, appear to be at relatively low risk for oxygen toxicity based on oxygen consumption, this is deceptive, given the very high share of resting cardiac output. C(a-v)O2 = arterial-venous oxygen content difference; V̇O2 = percentage of the body's total volume of oxygen consumption; QT = percentage of total body blood flow. Data from Reference 50.
