Brief Summary

Lung-protective ventilation (LPV) during general anesthesia can trigger the development of early postoperative pulmonary complication (PPC) and ventilator associated lung injury. One of the proven components of the LPV is low tidal volume (TV). Data on the positive end-expiratory pressure (PEEP) parameters adjustment in laparoscopic surgery, as well as the effects on the respiratory biomechanics, lung tissue and respiratory muscles damage are limited and not clear. The objective of the study is to evaluate the ability of the esophageal pressure (Pes) based controlled personalized PEEP adjustment, to improve the biomechanics of the respiratory system and oxygenation due to laparoscopic cholecystectomy.
