Figure 1 Values of pulmonary capillary wedge pressure, PASP, cardiac index, and PVR in patients using iNO (black circles) versus oxygen (black squares) preoperatively and at 24 and 48 hours after surgery. There was a significant decrease in PVR at 48 hours in patients using iNO compared to oxygen. *p < 0.005.

Figure 2 Changes compared to baseline of hemodynamic data in patients using oxygen (white bars) and iNO (black bars). Cardiac index increased much more significantly in patients receiving iNO at 24 and 48 hours (p <0.01 for both) compared to preoperative values.
