Fick's method calculation

WebDec 18, 2016 · The Fick equation is: where: VO2 = oxygen uptake CvO2 = mixed venous oxygen content CaO2 = arterial oxygen content And what it describes is: It’s a mass-balance equation that basically says that what goes in must come out, but how do you get from oxygen uptake to cardiac output? The key part to this is oxygen content. WebThus, the Fick principle involves the blood oxygenation process through the lungs and oxygen delivery to the tissues, where it is added and removed by a flow limited mechanism. By measuring the amount of oxygen carried by the blood, the total amount of blood needed to carry oxygen through the lungs could be calculated.
