Respiratory depression is a well known side effect of anesthesia, and a reason to give oxygen to the patient. However, the administration of oxygen doesn’t ameliorate hypercapnia as a diagnostic parameter unless ventilation is measured postoperatively. OFA has the advantage of requiring less oxygen postoperatively, allowing the measurement of oxygen saturation as an indication of sufficient breathing.

呼吸抑制是众所周知的麻醉副作用，也是给患者吸氧的原因。然而，诊断呼吸抑制的参数是高碳酸血症，除非术后测量通气，否则吸氧不能改善高碳酸血症。OFA的优势是术后较少吸氧，允许将血氧饱和度作为充分呼吸的指征。
