双水平正压通气治疗重叠综合征的临床疗效观察

摘要

目的 观察双水平正压通气(BiPAP)治疗重叠综合征(OS)的疗效.方法 选择14例于2010年1月～2011年10月在我院呼吸科住院治疗的重叠综合征(OS)患者给予BiPAP治疗,10cd后比较治疗前后血气分析,肺功能和多导睡眠图( polysomnography,PSG)的变化.结果 OS患者经BiPAP治疗后,血气分析提示PaO2、PaCO2及肺功能FEV1/FVC％较治疗前有明显改善,P＜0.05;PSG各参数显示呼吸紊乱指数(AHI)、最长呼吸暂停时间、最低血氧饱和度、平均血氧饱和度、慢波睡眠(Ⅱ+Ⅳ期)、总呼吸事件次数等指标明显改善,P＜0.05.结论 BiPAP呼吸机是治疗重叠综合征的一种有效,安全的方法.%To observe the clinical effects of bilevel positive airway pressure( BiPAP) ventilation in patients with overlap syndrome (OS). Methods 14 patients were treated with BiPAP. After 10 days,they were analysed that blood gas a-nalysis and lung function and polysomnography( PSG) before and after treatment. Results After treatment,they showed significant improvements on PaO2, PaCO2, FEV1/FVC% and datas of PSG, P <0. 05. Conclusion BiPAP ventilation is an effective and safe treatment in OS patients.
