EditorI read with interest the article by Schindler and colleagues1 concerning the accuracy of feedback controlled oxygen delivery into a closed anaesthesia circuit for measurement of oxygen consumption (V·O2-PF). The accuracy of the V·O2-PF was compared with V·O2 measurement by the Fick method (V·O2-Fick) at different FIO2. They found that V·O2-PF significantly exceeded the Fick-derived V·O2 in patients by mean 52 (SD 40) ml min1. The lack of agreement between the two methods was attributed to two factors:
