2. Fig. 1
The effect of inhaled NO on ventilation perfusion matching. NO significantly improved ventilation-perfusion matching, but no dose-response relationship was noted. When NO was discontinued, ventilation-perfusion matching returned to baseline levels. *p < 0.05 versus 0 ppm.

3. Fig. 2
NO decreased PA pressure, which returned to baseline levels on discontinuation of NO. No dose-response relationship was noted. *p < 0.05 versus 0 ppm.

4. Fig. 3
NO significantly improved transpulmonary vascular efficiency (TVE = pulmonary blood flow/total RV power). *p < 0.05 versus 0 ppm.

5. Fig. 4
Inhaled NO resulted in a significant increase in Pao2. When NO was discontinued, Pao2 returned to baseline values. *p < 0.05 versus 0 ppm.
