Accuracy of Estimating Resting Oxygen Uptake and Implications for Hemodynamic Assessment

The Fick principle (cardiac output [Qc ] = oxygen uptake [V o2 ]/arteriovenous oxygen difference) can be used to calculate Qc , with VO2 frequently estimated by derived equations. To compare the accuracy of measured versus estimated VO2 , data were analyzed from 2 studies in which VO2 at rest was me...
