WebThe direct oxygen Fick approach is the standard reference technique for cardiac output measurement. It probably is the most accurate method currently available, although there are many possibilities of introducing errors, and considerable care is needed. WebOct 15, 2024 · 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 calculations of intracardiac shunts from the arteriovenous oxygen ...
