OBJECTIVE
To study the characteristics of respiratory disturbance during REM sleep in OSAHS through the signals surveyed by polysomnography (PSG).
METHOD
The result of sleeping monitoring of 180 cases with OSAHS by PSG was reviewed, the AHI and the RIT index was used to evaluate the severity in different sleep stage as in REM and N-REM stage to find out the characteristics of the respiratory disturbance.
RESULT
The study showed that AHI index in mild group increased greatly in REM period (P < 0.05), but no significant changes between the moderate and severe groups. And the lowest oxygen saturation (LSaO2) was lower during REM stage than that during N-REM stage (P < 0.05).
CONCLUSION
(1) The time of REM in OSAHS patients often decreases according to their severity. (2) The respiratory disturbance during the stage REM is much severe than during the stage N-REM. The main manifestation is that the time of apnea-hypopnea is more longer and the AHI index does not significantly change. (3) The RIT index is more closely related to the severity of respiratory disturbance than AHI index.
目的
通过多导睡眠图（PSG）监测信号研究阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者快速眼动（REM）睡眠期呼吸紊乱的特点。
方法
回顾180例OSAHS患者PSG睡眠监测结果，采用呼吸暂停低通气指数（AHI）及呼吸紊乱指数（RIT）评估REM期和非快速眼动（N-REM）期等不同睡眠阶段的严重程度，以找出呼吸紊乱的特点。
结果
研究表明，轻度组AHI指数在REM期显著升高（P<0.05），而中度组和重度组之间无显著变化。且REM期最低血氧饱和度（LSaO2）低于N-REM期（P<0.05）。
结论
（1）OSAHS患者REM睡眠时间常随病情严重程度降低。（2）REM期呼吸紊乱比N-REM期严重得多。主要表现为呼吸暂停低通气时间更长且AHI指数无显著变化。（3）RIT指数比AHI指数与呼吸紊乱严重程度的相关性更强。
