Purpose Little is known regarding the influence of in-laboratory polysomnography (PSG) equipment on sleep position, especially on the prevalence of supine positioning, which in many cases may lead to a more severe sleep apnea diagnosis. The aim of this study was to assess the percentage of supine sleep during an in-laboratory PSG compared to that seen during a home sleep apnea test (HSAT). Methods This was a retrospective cohort study comparing in-laboratory PSG and HSAT using a peripheral arterial tone (PAT) technology device. Results Of 445 PSG and 416 HSAT studies analyzed, there was no significant difference in the proportion of supine sleep time between PSG (44%) and HSAT (45%, p = 0.53). Analysis of the differences in sleep position (supine versus non-supine), analyzed by sex, BMI (≥ 30 kg/m2 versus < 30 kg/m2), and age (≥ 60 years versus < 60 years), was significant only for women, who had more supine sleep during HSAT at 61 ± 24% than during PSG at 45 ± 26% ( p < 0.001). Conclusion Overall there was no difference in the percentage of supine sleep when comparing in-laboratory PSG to HSAT. However, women had more supine sleep with HSAT than with PSG.

实验室内多导睡眠图和家庭睡眠多导图对睡眠姿势的影响

目的 关于实验室内多导睡眠图 (PSG) 设备对睡眠姿势的影响知之甚少，尤其是对仰卧姿势的普遍影响，这在许多情况下可能导致更严重的睡眠呼吸暂停诊断。本研究的目的是评估实验室内 PSG 期间仰卧睡眠的百分比与家庭睡眠呼吸暂停测试 (HSAT) 期间所见相比的百分比。方法 这是一项使用外周动脉张力 (PAT) 技术设备比较实验室内 PSG 和 HSAT 的回顾性队列研究。结果 在分析的 445 项 PSG 和 416 项 HSAT 研究中，PSG (44%) 和 HSAT (45%, p = 0.53) 之间的仰卧睡眠时间比例没有显着差异。分析睡眠姿势的差异（仰卧与非仰卧），按性别、BMI（≥ 30 kg/m2 与 < 30 kg/m2）进行分析，和年龄（≥ 60 岁对比 < 60 岁），仅对女性有显着意义，她们在 HSAT 期间的仰卧睡眠时间为 61 ± 24%，比 PSG 期间的 45 ± 26% (p < 0.001)。结论 总体而言，将实验室内 PSG 与 HSAT 进行比较时，仰卧睡眠的百分比没有差异。然而，使用 HSAT 的女性比使用 PSG 的女性有更多的仰卧睡眠。
