OS和OSAS患者夜间缺氧和睡眠结构的分析

The Study of Hypoxemia and Sleep Structure in the Patients with Overlap Syndrome and Obstructive Sleep Apnea Syndrome

目的 探讨重叠综合征(overlap syndrome,OS)和阻塞性睡眠呼吸暂停综合征(obstrucfive sleep apnea syn-drome,OSAS)患者夜间缺氧和睡眠结构的分析。方法 对19例OS和25例OSAS患者进行肺功能和全夜多导睡眠(PSG)检查。结果 OS组SLT90%、S1+2显著高于OSAS组(P<0.01),睡眠效率显著低于OSAS组(P<0.01)。结论 OS患者较OSAS患者夜间缺氧更严重,睡眠结构改变明显。

Objective To investigate night-time hypoxemia and change of sleep structure in the Patients with Overlap Syndrome (OS) and Obstructive Sleep Apnea Syndrome(OSAS).Methods 19 patients with OS,25 with OSAS were measured with lung function and nocturnal polysomnography(PSG). Results The levels of SLT90% and S1 + 2 in patients with OS were significantly higher than those in patients with OSAS(P<0.01), the level of sleep efficiency was significantly lower than those in patients with OSAS (P<0.01). Conclusion The study showed that patients with OS had severe night-time hypoxemia and significant change in sleep structure.
