Not Applicable
Conditions
Morbid Obesity
Registration Number
NCT01002599
Lead Sponsor
University Health Network, Toronto
Brief Summary

This is a randomized controlled study in which morbidly obese patients undergoing bariatric surgery will be recruited in the preoperative clinic. Patients will be randomized into 2 groups to receive oxygen with Boussignac TM continuous positive airway pressure (CPAP) or conventional Venturi mask postoperatively immediately after extubation. The objective of the study is to examine if Boussignac TM CPAP results in improved oxygenation versus Venturi face mask when it is applied immediately after extubation in morbidly obese patients post bariatric surgery.
