Watch-PAT may provide an accurate and clinically effective portable monitoring method for the diagnosis of obstructive sleep apnea (OSA).
This study was designed to assess the accuracy and clinical efficacy of a wrist-worn portable device (Watch-PAT 100) to diagnose OSA.
Twenty-seven participants with suspected OSA underwent full polysomnography (PSG). Finally, 25 subjects successfully underwent portable monitoring using Watch-PAT after full PSG. The study population consisted of 21 males and 4 females, mean age 40.9 +/- 11.2 years (range 21-59). Mean body mass index (BMI) was 26.2 +/- 2.6 kg/m(2) (range 21.2-32.3). All PSG were manually scored according to the new scoring manual of the American Academy of Sleep Medicine (2007) and the Watch-PAT data were analyzed by the automatic algorithm.
There was a high correlation of apnea-hypopnea index (AHI) (r = 0.94, p < 0.001) and lowest oxygen saturation (LSAT) (r = 0.90, p < 0.001) between the PSG and the Watch-PAT. A good agreement was also found between PSG AHI, PSG LSAT and PAT AHI, PAT LSAT, respectively. There was a significantly high concordance of the severity of AHI (Kendall tau-b = 0.897, p < 0.001) between the PSG and the Watch-PAT.
Watch-PAT可能为阻塞性睡眠呼吸暂停（OSA）的诊断提供一种准确且临床有效的便携式监测方法。
本研究旨在评估一种腕戴式便携式设备（Watch-PAT 100）诊断OSA的准确性和临床疗效。
27名疑似OSA的参与者接受了全夜多导睡眠图（PSG）检查。最后，25名受试者在完成全夜PSG检查后成功使用Watch-PAT进行了便携式监测。研究人群包括21名男性和4名女性，平均年龄40.9±11.2岁（范围21 - 59岁）。平均体重指数（BMI）为26.2±2.6 kg/m²（范围21.2 - 32.3）。所有PSG均根据美国睡眠医学学会新的评分手册（2007年）进行人工评分，Watch-PAT数据通过自动算法进行分析。
PSG与Watch-PAT之间的呼吸暂停低通气指数（AHI）（r = 0.94，p < 0.001）和最低血氧饱和度（LSAT）（r = 0.90，p < 0.001）具有高度相关性。PSG AHI与PAT AHI、PSG LSAT与PAT LSAT之间也发现有良好的一致性。PSG与Watch-PAT之间AHI严重程度的一致性显著较高（Kendall tau-b = 0.897，p < 0.001）。
