Effect of protective lung ventilation on oxygenation and hemodynamics in obese patients

ABSTRACT

Background: The number of obese patients undergoing surgery, either bariatric or non-bariatric, is steadily increasing. These patients are more labile to the perioperative complications, such as hypoxemia, hypercapnia, and atelectasis. Intraoperative protective ventilation consisting of low tidal volume, high PEEP and recruitment maneuvers resulted in alveolar recruitment and optimization of intraoperative respiratory mechanics
