阻塞性睡眠呼吸暂停综合征患者睡眠呼吸紊乱曲线的一种新分型方法

目的 :探讨一种实用、合理的呼吸紊乱曲线分型方法。方法 :研究 2 0例经多导睡眠仪 (polysomno-graphy,PSG)确诊的阻塞性睡眠呼吸暂停综合征 (OSAS)患者及正常打鼾者的血氧饱和度、鼻口气流及胸腹运动同步曲线 ,提出一种新分型方法 ,并与标准分型比较其诊断价值。结果 :依据胸腹动度与鼻口气流的变化规律将呼吸紊乱曲线分为低通气、阻塞性低通气、阻塞性呼吸暂停、高阻塞性呼吸暂停 4型。新分型较标准分型能更好地反映患者的呼吸紊乱状况。结论 :新分型法符合 OSAS患者呼吸紊乱曲线变化的规律 ,能够反映患者占主流的呼吸紊乱曲线 ,具有较高的实用价值。

A new method for classifying respiratory events during sleep in OSAS

Objective:To explore a more useful and more precise method for classifying respiratory events during sleep in OSAS.Methods:20 consecutive patients referred to the sleep laboratory with suspected OSAS were examined by full-night PSG.A new four-types classification is presented through careful analysis of the airflow and thoracic/abdominal movement patterns.The differences between the new classification and the standard one are displayed.Results:According to different PSG signals characteristics, respiratory events are divided into four types:Hypopnea (Hyp),Obstructive Hypopnea (Ob.H),Obstructive Apnea (Ob.A) and High Obstructive Apnea (Hi.A) In classifying respiratory events the new one is more practical than the standard.Conclusion:The new four-types classification is more useful and reasonable as compared to the standard classification.
