Conditions

Anaesthesia undergoing robot-assisted laparoscopic radical prostatectomy

Interventions

Using respiratory ventilation (Engstrom Caredtation, GE Healthcare), interventions start after Trendelenburg position and pneumoperitoneum were established. Using PC-VG mode, the target volume is set

I:Eratio of 1:2, PEEP of 5 cmH2O. Setting 2

I:E ratio of 2:1, PEEP of 0 cmH2O Setting 3

I:E ratio of 3:1, PEEP of 0 cmH2O Setting 4

I:E ratio of 4:1, PEEP of 0 cmH2O

Eligibility

Sex/Gender

Male
