Design outcomes

Primary

Measure	Time frame
Changes in regional lung gas distribution obtained from EIT device and functional residual capacity change suggested by EELI among three groups with different settings of PEEP and RM at 8 time points (at the time of entering the room, introducing the general anesthesia, before starting the operation, 1 hour after the start of pneumoperitoneum and trendelenburg position, 2 hours after the start of pneumoperitoneum and trendelenburg position, immediately after the operation, 5 minutes afuter extubation).	—

Measure	Time frame
Lung compliance obtained from ventilator and blood gas analysis result obtained by arterial blood sampling among three groups with different settings of PEEP and RM at 8 time points (at the time of entering the room, introducing the general anesthesia, before starting the operation, 1 hour after the start of pneumoperitoneum and trendelenburg position, 2 hours after the start of pneumoperitoneum and trendelenburg position, immediately after the operation, 5 minutes afuter extubation).	—
