Arteriovenous Oxygen Difference

The arteriovenous oxygen difference, or a-vO2 diff, is the difference in blood oxygen content between arterial blood and venous blood. It is an indication of the amount of oxygen removed from the blood in the capillaries as the blood circulates through the body. The a-vO2 difference and cardiac output are the main factors that vary the body's total oxygen consumption and are important for measuring VO2. The a-vO2 difference is usually measured in milliliters of oxygen per 100 milliliters of blood (mL/100 mL)

Arteriovenous Oxygen Difference Calculator

Arteriovenous Oxygen Difference Calculator: represents the difference in oxygen content between upstream (arterial) and downstream (venous) in the circulating fluid.

CaO2: Arterial oxygen content.

CvO2: Venous oxygen content.

DavO2: arteriovenous difference in oxygen.

EO2: Tissue oxygen extraction, which corresponds to the fraction of arterial oxygen content (CaO2) taken up by the peripheral tissues for their metabolism.
