The relationship between oxygen uptake,cardiac output,and the arterial-venous oxygen difference is described mathematically by the
A)Hill equation.
B)Fenn equation.
C)Fick equation.
D)Frank-Starling law.

Question

Quizplus · Accepted Answer

The Fick equation relates oxygen consumption to cardiac output and the arterial-venous oxygen difference. It is expressed as VO2 = Q x (CaO2 - CvO2), where VO2 is oxygen uptake, Q is cardiac output, CaO2 is arterial oxygen content, and CvO2 is venous oxygen content. This equation is commonly used to evaluate exercise performance and cardiovascular function. The Hill equation applies to the binding of oxygen to hemoglobin, the Fenn equation relates oxygen consumption and carbon dioxide production, and the Frank-Starling law describes the relationship between cardiac output and ventricular filling.
