Association between inhaled nitric oxide treatment and long-term pulmonary function in survivors of acute respiratory distress syndrome

Table 3 Duration of exposure parameters (AUC) during mechanical ventilation from baseline through day 28 or discharge

AUC Parameter	Placebo (N = 41)	Inhaled NO (N = 51)	P Value
Inhaled NO (ppm days)^a	0	114 ± 102	NA
FiO₂ (% days)	7.6 ± 4.7	6.3 ± 4.5	0.151
PEEP (mmHg days)	113.4 ± 81.1	96.3 ± 75.9	0.261

^aValues are mean ± SD unless otherwise indicated. AUC, area under the curve; FiO₂, fraction of inspired oxygen; N, number; NO, nitric oxide; PaO₂, partial pressure of arterial oxygen; PEEP, positive-end expiratory pressure.
