83例睡眠鼾症多导睡眠图观察研究

目的 研究多导睡眠图和动态SaO2监测诊断睡眠呼吸暂停综合征(SAS)的意义。方法 运用多导睡眠仪整夜9h检测睡眠打鼾并疑有睡眠呼吸障碍门诊和住院病人83例。结果 52例诊断为不同程度的阻塞性睡眠呼吸暂停低通气综合征(OSAHS)，表明睡眠呼吸暂停或/和低通气，间断性SaO2下降，重症心率分布宽度增高，肢动频繁。结论 每小时呼吸暂停或/和低通气数、累计数、持续时间、呼吸紊乱指数(RDI)是OSAHS诊断和分度的可靠指标。SaO2≤90%时间占睡眠总时间的比例为单纯动态Sa02监测OSAHS提供诊断和分组的参考指标。

The role of polysommography and nocturnal dynamic oximetry in diagnose of Sleeping apnea syndrome: report of 83 cases

Objective To investigate the role of polysommography and nocturnal dynamic oximetry in diagnose of Sleeping apnea syndrome( SAS).Methods 83 snoring patients were examined by polysommography with full night (9 hours) monitor. Results 52 cases was diagnosed as OSAHS, who showed different degree of apnea, hypopnea,intermittent SaO2 descent and widened heart rate distribution, 4 patients showed increased PLM .Conclusion Thefrequency of apnea and hypopnea, duration of apnea ,duration of hypopnea and respiration disorder index are reliable parameters in diagnosing OSAHS.
