2. Fig. 1
Mean pulmonary artery pressure (MPAP; mean ± standard error of the mean) at each intervention in the severe and moderate hypoxia groups. A dose response exists in both groups, but the curve is much steeper in the severe hypoxia group, where the highest inhaled nitric oxide (NO) dose (80 ppm) is required to return the pulmonary artery pressure to baseline. (∗p < 0.05 compared with the same intervention in the moderate hypoxia group.)

3. Fig. 2
Inhaled nitric oxide dose response displayed as percent change in mean pulmonary artery pressure (mean ± standard error of the mean) at each dose in the severe and moderate hypoxia groups. There is less dilation at each dose in the severe versus the moderate group. (∗p < 0.05 compared with the same dose in the severe hypoxia group.)

4. Fig. 3
Inhaled nitric oxide dose response displayed as percent change in pulmonary vascular resistance (mean ± standard error of the mean) at doses of 5, 20, and 80 ppm in the severe and moderate hypoxia groups. There is less resolution in elevated pulmonary vascular resistance at each dose in the severe versus the moderate group. (∗p < 0.05 compared with the same dose in the severe hypoxia group.)
