[The change of oxygen consumption and oxygen delivery in patients undergoing heart surgery during perioperative period].
We examined the changes of oxygen consumption (Vo2), oxygen delivery (Do2) and Vo2/Do2 in 38 patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) during perioperative period. There were no significant correlations between Svo2 and cardiac index. The Vo2/Do2 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.
