5. Study Description
Brief Summary
The investigators hypothesized that positive end expiratory pressure (PEEP) would increase the regional oxygen saturation (rSO2).
Detailed Description
The investigators hypothesized that PEEP would increase the rSO2 during laparoscopic surgery by improving oxygenation.
