"Effect of Boussignac continuous positive airway pressure ventilation on PaO2 and PaO2/FIO2 ratio immediately after extubation in morbidly obese patients undergoing bariatric surqery: a randomized controlled trial." Journal of Clinical Anesthesia 34 (November): 562-570.0952-8180 (Print)http://hdl.handle.net/10400.2/10727Pathophysiological changes after laparoscopic Roux-en-Y gastric bypass may increase the risk of pulmonary complications in morbidly obese patients. The purpose of the study was to assess the impact of immediate postextubation use of Boussignac continuous positive airway pressure (CPAP) on arterial oxygenation in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass. The hypothesis is that the use of CPAP may improve oxygenation in the postoperative period when compared to Venturi mask.engAdultAirway extubationBlood gas analysisContinuous positive airway pressureFemaleForced expiratory volumeGastric bypassHumansHypoxiaIntubation, IntratrachealLaparoscopyMaleMasksMiddle agedObesity, MorbidOxygenOxygen inhalation therapyPostoperative careSpirometryVital capacityjournal article10.1016/j.jclinane.2016.06.024
