ABP = systemic arterial blood pressure; FiO2 = fraction of inspired oxygen; PaO2 = partial pressure of oxygen in arterial blood; PAOP = pulmonary arterial occlusion pressure; PAP = pulmonary arterial blood pressure; Pcap = pulmonary capillary pressure; PVR = total pulmonary vascular resistances; SEM = standard error of the mean. Group 3 = OA injury without terbutaline (n = 7); Group 4 = OA + terbutaline (n = 6); * P < 0.05 early recovery versus late recovery in group 4 (OA + terbutaline) (intra-group comparison by analysis of variance and the post-hoc test of Tukey-Kramer). |
