Intraoperative respiratory mechanics. (a) Dynamic respiratory system compliance. (b) Airway resistance. (c) Maximum airway pressure. (d) Mean airway pressure. Data are expressed as mean (sd). *P<0.05 at individual time points. The P-value at the corner of each panel shows the overall statistical difference between the groups.
