title: Oxygen consumption after cardiac surgery--a comparison between calculation by Fick's principle and measurement by indirect calorimetry.
abstract: 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.
