WebVO 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 use the method by the books because of gas concentrations, the Fick determination is used with the help of an assumed value for VO 2 (oxygen consumption). One of the common assumed values is 125 mL/min per ... WebResults have been shown to correlate closely with both dye dilution and Fick methods, though in low cardiac output states the Fick method is considered to be more reliable.
