WebThe Fick equation for cardiac output calculator needs all of the following three measurements in order to determine the CO. VO2 is the oxygen consumption measured by a spirometer in mL/min of pure gaseous oxygen. In practice, for this component, an assumed value is used because of the difficulty of real measurement. ... WebCardiac output (CO) was obtained in each patient via both thermodilution and the Fick method, using oxygen consumption, SpO(2) and Scvo(2). Results: COs ranged between 2 and 2.3 (in the Fick and thermodilution methods, respectively) and 19 or 19.5 l/min (respectively). Mean thermodilution-derived CO was 6.2 +/- 4.2 l/min whereas the Fick's …

WebThe Fick equation starts from: VO 2 = (CO x C a) - (CO x C v) Which means that the cardiac output equation is: CO = VO 2 / (C a - C v) While in practice it can be hard to … WebThe Fick Equation. Represents the relationship of the body's oxygen consumption (VO2), to the arterial-venous oxygen difference (a-vO2) and cardiac output (Q) Equation for Fick Equation. VO2= Q x a-vO2diff. Arterial-Venous Oxygen Difference. The difference in oxygen from the arteries to the veins. Oxygen in arteries minus the oxygen in the veins.
