Thirty male patients evaluated sequentially for sleep apnea syndrome by all-night clinical polysomnography were compared for apnea plus hypopnea index (A + HI) during the time in the side versus time in the back sleep posture. For 24 subjects of this sample, who occupied both major body positions during the evaluation night, the apnea index was found to be twice as high during the time spent sleeping on their backs as it was when they slept in the side position. This difference is reliable and inversely related to obesity. Five patients meeting diagnostic criteria for sleep apnea on an all-night basis fell within normal limits while in the side sleep position. This suggests sleep position adjustment may be a viable treatment for some nonobese sleep apnea patients.
通过整夜临床多导睡眠图对30名男性睡眠呼吸暂停综合征患者进行连续评估，比较他们侧卧睡眠和仰卧睡眠时的呼吸暂停加低通气指数（A + HI）。在该样本中，有24名受试者在评估夜间占据了两种主要体位，结果发现他们仰卧睡眠时的呼吸暂停指数是侧卧睡眠时的两倍。这种差异是可靠的，并且与肥胖呈负相关。有5名整夜符合睡眠呼吸暂停诊断标准的患者在侧卧睡眠时呼吸暂停指数处于正常范围。这表明睡眠体位调整可能是一些非肥胖睡眠呼吸暂停患者的可行治疗方法。
