Ten male patients selected as having sleep apnea predominantly of the obstructive type associated with the supine sleep position on their evaluation night were trained for 1 additional night to avoid the back sleep position by wearing a gravity-activated position monitor/alarm on the chest. This device emitted an auditory signal if the patient remained supine for more than 15 s. The number of apneic events was significantly reduced, as were the number of episodes of significant O2 desaturation. While wearing the alarm, the apnea index of seven patients remained within or near normal limits. On a follow-up night, with only instructions to maintain the lateral decubitus posture, five patients remained significantly improved. Sleep position training may be appropriate as a single or interim treatment for a significant number of sleep apnea patients who have position-related obstruction.
十名男性患者在评估当晚被判定主要患有与仰卧睡眠姿势相关的阻塞性睡眠呼吸暂停，他们接受了额外一晚的训练，通过在胸部佩戴重力激活的体位监测器/警报器来避免仰卧睡眠姿势。如果患者仰卧超过15秒，该设备就会发出听觉信号。呼吸暂停事件的数量显著减少，严重氧饱和度下降的发作次数也显著减少。佩戴警报器时，七名患者的呼吸暂停指数保持在正常范围内或接近正常范围。在随访的夜晚，仅给予保持侧卧位的指示，五名患者仍有显著改善。对于大量患有与体位相关阻塞的睡眠呼吸暂停患者，睡眠姿势训练可能适合作为单一治疗或临时治疗方法。
