微动敏感床垫式睡眠监测仪在睡眠呼吸暂停低通气综合征诊断中的意义

目的 探讨微动敏感床垫式睡眠监测仪(简称床垫系统)的睡眠监测效果.方法 经多道睡眠图(PSG)监测诊断为阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的患者40例,2～5 d内相同条件再次接受床垫系统(RS-611型)睡眠临测,对两种方法 获得的呼吸和睡眠指标进行比较.17名健康成年人作为对照组也进行了这两种睡眠监测.以PSG结果 为金标准,了解床垫系统监测的可靠性.结果 PSG诊断为OSAHS的40例患者,床垫系统均诊断为OSAHS.睡眠监测结果 ((-x)±s)比较:呼吸暂停低通气指数(AHI)分别为(35.6±21.3)和(37.6±18.8)次/h,快速动眼(REM)期睡眠构成比分别为(15.0±4.5)%和(15.8±6.3)%,差异均无统计学意义(t值分别为1.867和1.014,P值均>0.01);患者的深、浅睡眠构成比,睡眠效率和阻塞性呼吸事件比率,两种监测方法 差异均有统计学意义(P值均<0.01).OSAHS患者按照PSG诊断进病情分度,轻、中、重度患者分别为11、7、22例;按照床垫系统的分度分别为2、19、19例.健康对照组17名受试者PSG监测结果 均为正常,而床垫系统将其中2例诊断为轻度OSAHS.床垫系统诊断OSAHS的灵敏度为100.0%,特异度为88.2%.结论 微动敏感床垫对睡眠呼吸暂停低通气综合征的诊断与PSG有较好的一致性,可以作为一种临测方法 试用于临床工作.

Comparative analysis of polysomnography and micro-sensitive mattress-sleep monitor used for obstructive sleep apnea hypopnea syndrome

Objective To assess the efficiency of mattress-type micro sensitive monitor(MMSM) in sleep monitoring. Methods Forty patients diagnosed as obstructive sleep apnea-hypopnea syndrome (OSAHS) by polysomnography (PSG) were randomly chosen, then received MMSM examination within 2 -5 days. The results of both methods were compared, using the respiratory disturbance index, sleep efficiency, and obstructive factors as indicators. Results All 40 patients were diagnosed as OSAHS, which were consistent with the results of PSG. There was no statistical difference when comparing the apnea hypopnea index (AHI, (-x)± s, 35.6 ± 21.3 and 37. 6 ± 18. 8, respectively) and the ratio of rapid eyes movement (REM) stage (15.0 ± 4. 5) % and (15.8 ± 6. 3) %, respectively (t were 1. 867 and 1. 014,P >0. 01). Some statistical sense was found when patients'deep sleep, shallow sleep and sleep efficiency were compared (P <0. 01). According to the severity diagnosed by PSG, patients with mild, moderate and severe OSAHS were 11, 7 and 22 cases, respectively, Comparing by MMSM, 2, 19 and 19 cases,respectively. Among seventeen volunteers diagnosed by PSG as normal subjects, 2 of them were diagnosed as mild OSAHS. The sensitivity of MMSM was 100. 0% and the specificity was 88. 2%. Conclusions With regard to the diagnosis of OSAHS, MMSM is well consistent with PSG. The MMSM can be applied clinically as a monitor technique.
