WebFick equation: CO is calculated from the difference in oxygen saturation between the arterial and venous blood (AVO2 difference) as well as the rate of oxygen consumption at the time the arterial and venous blood samples are drawn. Oxygen consumption can be calculated directly but is most often estimated by validated equations. WebAbstract. The need to quantify blood flow through the heart has led to the development of different techniques for its measurement. The 3 main approaches are the Fick method, dye dilution, and thermodilution techniques. The latter 2 are based on the use of indicators that indirectly quantify blood flow. These have slowly been developed over ... gina matthews facebook https://i2inspire.org
