Figure 2

Effect of salmeterol on airway pressures and inspiratory resistance mean values. (a) Mean values (± 1 SD) of peak airway pressure (Ppk) and intrinsic positive end-expiratory pressure (PEEPi) at baseline and up to 12 hours after salmeterol administration. (b) Mean values (± 1 SD) of minimum inspiratory resistance (Rint) and maximum inspiratory resistance (Rrs) at baseline and up to 12 hours after salmeterol administration. *Significantly different from baseline values (P < 0.05, Wilcoxon signed rank test). SD, standard deviation.
