This will include well known generally protective settings for mechanical ventilation of patients, concerning volumes, pressures, respiratory rate, inspiratory gases and ventilation maneuvers.\n\nThe rest of participants will be ventilated with the lowest possible Driving Pressure (ΔP). This will be similar to PMV in the chosen volumes, respiratory rate, inspiratory gases and ventilation maneuvers. However, the pressure inside lung at the end of expiration, eg Positive End Expiratory Pressure (PEEP), will be not be preset for every patient. Initially, the investigators will perform a maneuver that will quantify each individual's lung characteristics and mechanics. According to this, the investigators will find the exact PEEP that seems to suit each patients lungs most, and use this perioperatively, trying to provide lungs the best conditions every time.\n\nAfter the completion of the operation, all the patients will be screened for PPCs, via arterial blood testing and chest X ray, and the results will be statistically analyzed trying to find if any of the forementioned strategies of mechanical ventilation surpasses the other concerning PPCs appearance. PPCs include atelectasis, respiratory failure, bronchospasm, pleural effusion, pneumonia, aspiration and pneumothorax.\n\nFurthermore hospital stay, ICU need and mortality will be noted. Finally, measurements of perioperative lung pressures, volumes and derived variables will be noted and compared statistically as well.",[26,27,28,29,30,31,32,33,34,35],"Postoperative Pulmonary Atelectasis","Postoperative Pulmonary Complications","Postoperative Respiratory Failure","Postoperative Bronchospasm","Postoperative Pleural Effusion","Postoperative Pneumothorax","Postoperative Pneumonia","Postoperative Aspiration Pneumonitis","Mechanical Power","Driving Pressure",[35,34,37,38,27,28,39],"Atelectasis","Pulmonary Complications","Elastic Power","RECRUITING","2026-02-08",{"date":43,"type":44},"2026-02-11","ACTUAL",{"date":46,"type":44},"2025-11-03",{"date":48,"type":20},"2027-11-30",{"name":50,"class":51},"University General Hospital of Patras","OTHER"]
