Background: During muscular exercise, a negative correlation has been demonstrated between the value of mixed venous oxygen saturation (S hivin V-O-2) and the level of muscular work, expressed at each level as the ratio of oxygen uptake ( ovrhdot V-O-2) to each subject's maximal oxygen uptake ( ovrhdot V-O-2max). Because the immediate postoperative period is associated with an increase in whole body oxygen demand, and in this regard resembles the effects of muscular exercise, a similar correlation may exist during this period. Methods: ovrhdot V-O-2max was determined in 11 patients 3-5 days before coronary artery bypass surgery.
