Overview
Brief Summary
The study aims to compare the efficacy of Nasal High Flow Therapy (NHF) with low-flow oxygen supplementation in improving postoperative intermittent desaturations. If so, this mode of therapy would provide a cost effective, relatively easy to implement, and better tolerated treatment to Continuous Positive Airway Pressure (CPAP) for oxygen stabilization.
Detailed Description
Patients identified preoperatively with previously diagnosed obstructive sleep apnea (intermittent collapse of upper airway while asleep) who refuse Continuous Positive Airway Pressure use after surgery and are treated with routine postoperative supplemental oxygen alone (1 liters per minute) will have more oscillation of oxygen saturation during the night (measure by overnight oximetry) than those treated with high nasal flow air insufflator (Fisher \& Paykel Airvo 2 device) with same amount of oxygen supplement (1 liters per minute).
