In 1870, he devised Fick's principle, which allows the measurement of cardiac output and calculations of intracardiac shunts from the arteriovenous oxygen difference. The method was later generalized to the Fick principle, according to which the flow of an indicator taken up or released by an ...
Then, cardiac output can be calculated using the following equation. Q ϭ (V˙CO2)STPD (C(vϪa)CO2)STPD (9) Q ϭ cardiac output (L/min); (V˙CO2) STPD ϭ pulmonary carbon dioxide exchange under STPD conditions (mL/min); (C(v-a)CO2)STPD ϭ venoarterial difference in ...
Fick's name in physics is associated to the laws of diffusion of solutions, and in medicine to the principle of cardiac output calculation. In 1855, he proposed Fick's laws on gas diffusion. In 1870, he devised Fick's principle, which allows the measurement of cardiac output and ...

Introduction:\nThere are known sources of error in cardiac index calculated by the Fick method with LaFarge estimates of oxygen consumption (eFick CI) and in cardiac index measured by thermodilution (TDCI). In a large adult cohort, there was only modest correlation between eFick CI and TDCI....
Cardiac indexThermodilutionEstimated Fick methodLaFarge equationCardiac index (CI) may be derived from the Fick method, using measured or estimated oxygen consumption (VO2), or from thermodilution. In children, LaFarge VO2estimates correlate poorly with measured VO2values. In a large adult cohort, ...
