Individualized Selection of PEEP in Patients Affected by Expiratory Flow Limitation

The goal of this clinical trial is to compare different mechanical ventilation settings in Patients undergoing laparoscopic surgery and affected by Expiratory flow limitation. The main question\[s\] it aims to answer are: * If individualizing mechanical ventilation on expiratory flow limitation can reduce pulmonary postoperative complications; * If patients with expiratory flow limitation have a higher incidence of pulmonary postoperative complications as compared to patients with no expiratory flow limitation; Participants will be screened for expiratory fow limitation and patients with positive screening will be randomized into two groups. Each group will receive a different intraoperative mechanical ventilation: * Personalized positive end-expiratory pressure based on EFL * Standard of care positive end-expiratory pressure Researchers will then compare the two groups to see if the incidence of pulmonary postoperative complications in the first 7 days after surgery is different.
