Jul 7, 2014 В· Cardiac output (CO) using the Fick principle (O 2 consumption) is calculated as follows: CO = [O 2 consumption (ml/min)]/ A-Mixed Venous O 2 difference (ml O 2 / 100ml blood) x 10. The indirect version of 2 days ago В· Adolf Eugen Fick (1829-1901) in 1870, was the first to measure cardiac output; assumes oxygen consumption is a function of rate of blood flow and rate of oxygen pick pick up by RBC’s. This output converts to a normalized value that accounts for the patient's body size. Assuming that the concentration does not change significantly throughout the rebreathing period, the terms associated with Cv CO2 cancel each other out and are not needed to calculate cardiac output. 0cm/2)^2 x 19cm = 60 cm^3 or 60 ml If the heart rate is 100 then Cardiac Output = HR x SV = 100 beats/min x 60 ml/beat = 6000 ml/min or 6.
