A series of 50 patients were studied to determine if post cardiopulmonary bypass (CPB) cardiac output (CO) could be predicted based upon in-line venous oxygen saturation (SvO2) values generated as CPB was being terminated. After rewarming, the arterial pump flow (APQ) was varied and resultant changes in SvO2 recorded. At low flow (600 ml/min), just prior to terminating CPB, the SvO2 was recorded and plotted on a linear graph generated from the previous data. The CO predicted by the low flow SvO2 correlated well with post-CPB measurements of the CO. (r = 0.82, p<. 0001)
