Conditions

Atelectasis

Interventions

PCV:In the PCV group, the initial ventilation mode was volume-controlled (the same setting of volume-controlled ventilation) and after CO2 pneumoperitoneum was created, the ventilator mode was changed
VCV:In the VCV group, the ventilation mode was volume-controlled during the entire operation: a tidal volume of 8 mL/kg of ideal body weight (IBW)
