全电脑无纸记录多导睡眠图诊断睡眠呼吸暂停的评价

Eveluation of accuracy of healthdyne nightwatch to monitor sleep breathing disorder

目的了解全电脑无纸记录多导睡眠图（ＮＷ）与经典的有纸记录多导睡眠图（ＰＳＧ）比较，其诊断睡眠呼吸暂停的可靠性及优越性。方法用ＮＷ与经典的ＰＳＧ对同一睡眠呼吸暂停综合征（ＳＡＳ）患者，在同一夜进行同步对照观察，共检测２０例患者，对其中１５例患者进行家庭监测。结果ＰＳＧ的呼吸紊乱指数（ＡＨＩ）为２８．６±６．９，ＮＷ测得的ＡＨＩ为２８．７±７．０；ＰＳＧ的最低血氧饱和度为７３．５％±２．８％，ＮＷ为７４．５％±３．２％。在ＡＨＩ≥５和≥１０两个诊断标准上的诊断一致率分别为９３．７％和９５．３％。结论全电脑多导睡眠图具有省时、省力、可携带等优点，是对经典的有纸记录的ＰＳＧ的一种补充，在绝大多数不需了解详细睡眠结构的患者，ＮＷ可以取代ＰＳＧ。

Objective To study the adventage of computerized portable polysomnograph (healthdyne night watch, NW) compared to standard paper scoring polysomnograph (PSG). Method NW was used to monitor the same patient with sleep apnea syndrome at the same night and compared with standard PSG. Result Apnea and hypopnea index (AHI) recorded by PSG was 28.6±6.9 versus 28.7± 7.0 recorded by NW. Mean lowest SaO 2 recorded by PSG was 73.5%±2.8% versus 74.5%±3.2% recorded by NW. Using a PSG value of AHI≥5 and ≥10 as the diagnostic criteria, the diagnostic agreement of NW was 93.7% and 95.3%, respectively. Conclusion The computerized portable polysomnograph (NW) saves time and labour. It could be used in patient′s home or ward and could replace PSG in most situations.
