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 ...
Use of assumed versus measured oxygen consumption for the determination of cardiac output using the Fick principle Assumed oxygen consumption (VO2) is increasingly used as a convenient surrogate for measured VO2 for calculation of cardiac output. T... Andreas,Wolf,MD,... - 《Catheterization & Ca...
Though TD CO carried the least bias, both it and all methods of iFick calculation tend to overestimate CO and have poor agreement when compared to the direct Fick method. These imprecise CO measurements could lead to poor clinical decisions in VAD patients and misjudgment of transplant candidacy...
As with every method of cardiac output measurement, the obtained value of cardiac output should be interpreted with knowledge of the actual hemody- namic circuit with the potential existence of shunts. Possible limitations of the mCO2F method are the potential calculation errors due to a too ...

The cardiac output (CO) may be calculated by the Fick method using the total oxygen consumption. Arterial and mixed venous blood oxygen content is needed for the calculation. The mixed venous blood is obtained from the pulmonary artery by right heart catheterization. However it is controversial ...
Calculation of VO2 using the new cardiac output technology had good repeatability compared with direct measurement, probably because of the high precision of measurement of cardiac output.doi:10.1097/00132586-199612000-00058Bizouarn PBlanloeil Y
