Overview
Brief Summary
Ventilation with low tidal volume and high PEEP (positive end expiratory pressure) has been shown to improve oxygenation in patients with ARDS (acute respiratory distress syndrome). In obese patients undergoing laparoscopic bariatric surgeries, the risk of postoperative pulmonary complications (PPCs) increases significantly with general anesthesia. Previous studies have shown that protective lung ventilation strategies could improve intraoperative oxygenation and lung mechanics.
In this study would compare the effect of optimum individualized high PEEP versus standard PEEP - on postoperative pulmonary complications
