WebFick method. method for measuring cardiac output by which the rate of oxygen consumption by the lungs is divided by the arteriovenous oxygen difference to give the rate of blood flow across the pulmonary capillaries and the cardiac output. WebSep 2, 2024 · Consequently, cardiac output calculated by the Fick method is less than that obtained by dilution techniques or direct measurements of cardiac output by electromagnetometry (Light 1988). For example, Light found that VO 2 could be overestimated by as much as 15% in a canine model of pneumonia (Light 1988).
