We examined the changes of oxygen consumption (VO-2), oxygen delivery (DO-2) and VO-2/DO-2 in 38 patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) during perioperative period. There were no significant correlations between SVO-2 and cardiac index. The VO-2/DO-2 showed a good level at pre-CPB and 1 hour after CPB, but the value became deteriorated 4 and 12 hours after CPB. These data suggest that we should be careful about the oxygen debt in tissue 4 and 12 hours after CPB.
