Selected measurements on breathing oxygen and NO/oxygen and after the discontinuation of NO
| Baseline | NO | After NO | |
| PAP (torr) | 26.1 (2.5) | 25.1 (2.8) | 27.6 (4.0) |
| PVR (dyne.s.cm–3) | 183.1 (36.7) | 137.2 (34.3) | 162 (56.6) |
| CO (l/min) | 5.9 (0.4) | 8.2 (1.1) | 6.5 (1.2) |
| PaO2 (kPa) | 11.3 (0.6) | 11.5 (0.6) | 11.51 (0.7) |
Values are mean (SE).
Baseline = breathing supplemental oxygen/air before NO administration; NO = after breathing NO for 24 hours; after NO = breathing oxygen/air for 24 hours after stopping NO; PAP = pulmonary artery pressure; PVR = pulmonary vascular resistance; CO = cardiac output; Pao 2 = arterial oxygen tension.
