Mean pulmonary artery pressure in pigs after endotoxin induced systemic inflammation. Values are represented as means ± SEM for CO treated animals (open circles, n = 10 except at 270 and 300 min where n = 9) and controls (closed circles, n = 10 except at 150, 180 and 210 min where n = 9 and at 240, 270 and 300 min where n = 8). Endotoxin was administered (0.05 μg/kg/h) just after time 0, reaching maximum infusion rate (0.25 μg/kg/h) at 30 min. CO was administrated just after time -60 min. No significant difference between the groups (ANOVA F(1, 9) = 0.158).
