We assessed the accuracy of a wrist-worn device WatchPAT 200 for the diagnosis of obstructive sleep apnea (OSA) and sleep and wakefulness indicators compared to standard polysomnography (PSG) using American Academy of Sleep Medicine (AASM) criteria. Twenty-eight adults with suspected OSA underwent a standard in-hospital PSG while wearing a WatchPAT 200. PSG events were manually scored using AASM criteria; WatchPAT 200 data were collected and analyzed by an automatic algorithm. The accuracy of WatchPAT 200 algorithm in apnea hypopnea index (AHI) and sleep-wake detection was compared to standard PSG methodology. The study population consisted of 21 males and 7 females, mean age of 47.45 ± 13.46 years, and mean body mass index of 29.99 ± 5.74 kg/m(2). For AHI, the mean PSG score for events per hour was 23.00 ± 21.55 compared to a mean score of 25.99 ± 19.09 for WatchPAT (r = 0.92, P < 0.001). The agreement of the sleep-wake assessment based on 30-s bins between the PSG and the WatchPAT was 89 ± 6 %. WatchPAT 200 detected OSA based on AHI with comparable accuracy, and provided a reasonably accurate estimation of sleep and wakefulness in patients with OSA on an epoch-by-epoch basis.
我们评估了腕戴式设备 WatchPAT 200 在诊断阻塞性睡眠呼吸暂停（OSA）和睡眠及觉醒指标方面的准确性，与使用美国睡眠医学学会（AASM）标准的标准多导睡眠图（PSG）进行比较。28 名疑似 OSA 的成年人在佩戴 WatchPAT 200 的同时进行了标准的住院 PSG。使用 AASM 标准对 PSG 事件进行手动评分；由自动算法收集和分析 WatchPAT 200 数据。比较了 WatchPAT 200 算法在呼吸暂停低通气指数（AHI）和睡眠觉醒检测中的准确性与标准 PSG 方法。研究人群包括 21 名男性和 7 名女性，平均年龄为 47.45 ± 13.46 岁，平均体重指数为 29.99 ± 5.74 kg/m2。对于 AHI，每小时 PSG 评分的平均事件数为 23.00 ± 21.55，而 WatchPAT 的平均评分则为 25.99 ± 19.09（r = 0.92，P < 0.001）。PSG 和 WatchPAT 之间基于 30 秒的睡眠觉醒评估的一致性为 89 ± 6%。WatchPAT 200 基于 AHI 检测 OSA 的准确性相当，并且能够在逐时基础上对 OSA 患者的睡眠和觉醒进行合理准确的估计。
