Is regular oxygen supplementation safe for obese postoperative patients?

[摘要] Postoperative hypoxemia is common. A prospective blinded observational study1 found that 21% of noncardiac postoperative patients had a pulse oxygen saturation less than 90% for at least 10 minutes per hour in the first 48 hours after surgery, and 3% had severe hypoxemia (pulse oxygen saturation < 80% for at least 30 minutes). Of note, most of the patients received supplemental oxygen for only a few hours after surgery, and standard observation by the nursing staff seriously underestimated the severity of hypoxemia.
