WebOxygen Consumption. Oxygen consumption (O2) is defined as the volume of oxygen consumed in 1 minute and may be calculated by the Fick principle: From: Critical Care … WebFick's principle allows highly accurate calculation of cardiac output. Total oxygen consumption, VO 2, in the tissues must equal the delivered oxygen less the returned oxygen. Delivered oxygen is equal to cardiac output multiplied by arterial oxygen content (C a, determined in a systemic artery).
