a, Mean of peak airway pressure at different time points; b, Mean of mean airway pressure pressure at different time points; c, Mean of tidal volume at different time points. a, Peak airway pressure pressure at T1 to T3 were significantly higher than all pressures at T0.5 and T4 (p < 0.001 for comparisons). b, Mean airway pressure at T1 to T3 were significantly higher than all pressures at T0.5 and T4 (p < 0.001 for comparisons). c, Tidal volume at T1 and T2 were significantly lower than the values at T0.5, T3 and T4 (p < 0.001 for comparisons). PP: peak airway pressure; PM: mean airway pressure; TV: tidal volume; T0.5: tracheal tube cuff pressure adjusted to 25 cmH20; T1: 15 min after pneumoperitoneum; T2: 30 min after pneumoperitoneum; T3: 45 min after pneumoperitoneum; T4: 15 min after exsufflation
