The Apnea Plus Hypopnea Index (A + HI) of 60 male positional sleep apneics was analyzed by sleep stage to determine if positional differences are limited to NREM sleep. Differences in apnea severity by sleep position were found to persist in REM sleep and to be of equal extent to those differences found in NREM sleep, despite the fact that there is also a significant increase in the frequency of apneic events associated with REM sleep. The positional effect persists in REM sleep, making treatments to control sleep posture a viable option.
对60名男性体位性睡眠呼吸暂停患者的呼吸暂停低通气指数（A+HI）按睡眠阶段进行分析，以确定体位差异是否仅限于非快速眼动睡眠。结果发现，尽管与快速眼动睡眠相关的呼吸暂停事件频率也显著增加，但睡眠体位导致的呼吸暂停严重程度差异在快速眼动睡眠中依然存在，且与非快速眼动睡眠中的差异程度相同。体位效应在快速眼动睡眠中持续存在，这使得控制睡眠姿势的治疗成为一种可行的选择。
