Figure 1From: Cardiac filling volumes versus pressures for predicting fluid responsiveness after cardiovascular surgery: the role of systolic cardiac functionBaseline filling pressures (PAOP, CVP) versus change in cardiac index (CI) when global ejection fraction (GEF) is low (<20%): r = -0.57, P = 0.008 and r = -0.44, P = 0.010, respectively.Back to article page
