Oxygen consumption calculated by Fick's principle (cVO2) was compared to oxygen consumption measured (mVO2) by indirect calorimetry (Deltatrac Metabolic Computer) in 10 patients in the post-operative period after cardiac surgery. For 50 pairs of measurements the mean difference (mVO2-cVO2) was 34 +/- 27 ml/min.m2. The limits of agreement were -20 ml/min.m2 to 88 ml/min.m2. These results showed that cVO2 and mVO2 were not interchangeable in this study.
通过菲克原理计算的氧耗量（cVO2）与通过间接量热法（Deltatrac代谢计算机）测量的10例心脏手术后患者术后的氧耗量（mVO2）进行了比较。在50对测量值中，平均差值（mVO2 - cVO2）为34±27 ml/min·m²。一致性界限为-20 ml/min·m²至88 ml/min·m²。这些结果表明，在本研究中cVO2和mVO2不可互换。
