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

Obstructive Sleep Apnea (OSA) is when a person stops breathing repeatedly during sleep.
Breathing stops because the airway collapses and prevents air from getting into the
