研究目的：确定孕妇动态多导睡眠监测(PSG)获得的关键变量与手腕佩戴的Watch-PAT 200设备之间的关系。方法：在这项前瞻性队列研究中，妊娠晚期的妇女使用22通道MediPalm系统和Watch-PAT 200设备进行了整夜的家庭PSG。PSG由盲人、有经验的技术专家使用AASM 2007标准进行评分；Watch-PAT由制造商的专有软件自动评分。结果：总共研究了31名孕妇。平均年龄30.2±7.1岁，平均孕周33.4±3.0周，平均体重指数31.9±8.1 kg/m(2)，未经产妇占39%。PSG和Watch-PAT产生的关键变量在很大范围内有很好的相关性，包括呼吸暂停低通气指数(呼吸暂停低通气指数，r=0.76，p<；0.001)；呼吸紊乱指数(呼吸紊乱指数，r=0.68，p<；0.001)，平均血氧饱和度(r=0.94p<；0.001)和最低血氧饱和度(r=0.88，p<；0.001)。AHI>；=5和RDI>；=10的曲线下面积分别为0.96和0.94。PSG的第三阶段睡眠和Watch-PAT的深度睡眠之间的关联性很差。Watch-PAT倾向于高估RDI，尤其是在病情加重时。结论：在孕妇中，Watch-PAT对诊断阻塞性睡眠呼吸暂停表现出极高的敏感性和特异性。Watch-PAT可能会高估RDI，特别是在RDI值较高的情况下。
Study Objectives: To determine the relationships between key variables obtained from ambulatory polysomnography (PSG) and the wrist-worn Watch-PAT 200 device in pregnant women.Methods: In this prospective cohort study, women in their third trimester of pregnancy underwent full overnight home PSG using the 22-channel MediPalm system and the Watch-PAT 200 device. PSGs were scored by a blinded, experienced technologist using AASM 2007 criteria; the Watch-PAT was scored automatically by the manufacturer's proprietary software.Results: A total of 31 pregnant women were studied. Mean age was 30.2 +/- 7.1 years; mean gestational age was 33.4 +/- 3.0 weeks; mean BMI was 31.9 +/- 8.1 kg/m(2); 39% of women were nulliparous. Key variables generated by PSG and Watch-PAT correlated well over a wide range, including the apnea-hypopnea index (AHI, r = 0.76, p < 0.001); respiratory disturbance index (RDI, r = 0.68, p < 0.001), mean oxygen saturation (r = 0.94, p < 0.001), and minimum oxygen saturation (r = 0.88, p < 0.001). The area under the curve for AHI >= 5 and RDI >= 10 were 0.96 and 0.94, respectively. Association between stage 3 sleep on PSG and deep sleep on Watch-PAT was poor. Watch-PAT tended to overscore RDI, particularly as severity increased.Conclusions: Among pregnant women, Watch-PAT demonstrates excellent sensitivity and specificity for identification of obstructive sleep apnea, defined as AHI >= 5 on full PSG. Watch-PAT may overestimate RDI somewhat, especially at high RDI values.
