Effect of Alveolar Recruitment on Oxygenation and Carbon Dioxide Elimination During Laparoscopic Bariatric Surgery and Comparison With Pressure Controlled and Volume Controlled Ventilation

Abstract

BACKGROUNDArterial oxygenation is inversely proportional to body mass index (BMI) in morbidly obese individuals. Alveolar recruitment maneuver consists of sustained insufflations, mainly with the use of positive end expiratory pressure (PEEP). We investigated the effects of alveolar recruitment on arterial oxygenation and carbon dioxide (CO2) elimination and compared the same with volumecontrolled and pressure-controlled ventilation during laparoscopic sleeve gastrectomy in morbidly obese patients.
