STUDY OBJECTIVE This two-part study was designed to determine the effect of supplemental oxygen on the detection of hypoventilation, evidenced by a decline in oxygen saturation (Spo(2)) with pulse oximetry. DESIGN Phase 1 was a prospective, patient-controlled, clinical trial. Phase 2 was a prospective, randomized, clinical trial. SETTING Phase 1 took place in the operating room. Phase 2 took place in the postanesthesia care unit (PACU). PATIENTS In phase 1, 45 patients underwent abdominal… Expand
