OSA is a common comorbidity in people undergoing surgical procedures, with rates as high as 91% in those undergoing bariatric surgery. OSA is an important risk factor for adverse postoperative outcomes including cardiac complications, opioid-induced ventilatory depression, and unplanned intensive care unit transfers.
