Web3 de nov. de 2024 · 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. involves measurement of oxygen concentration of arterial and venous blood and subsequent calculation of O2 consumption. Q can then be derived. WebThe cardiac output is determined by multiplying the heart rate and blood volume ejected by each ventricle during each beat (stroke volume). Cardiac output= heart rate X stroke volume. The normal value of heart rate is 72/min, and stroke volume is 80 mL/beat. So, the cardiac output formula = 72 beat/min X 0.08 L/beat = 5.5L/min.
