【摘要】 目的:探讨阻塞性睡眠呼吸暂停综合征(OSAS)患者日间清醒状态下的血氧变化及其与夜间睡眠低氧的关系。方法:观察12例单纯鼾症患者和67例(轻中度29例,重度38例)经多导睡眠仪监测诊断为OSAS的患者,在行夜间多导睡眠监测基础上的日间动脉血气分析,结果:发现重度OSAS患者日间动脉血氧分压降低,且随着呼吸紊乱指数(AHI)增加,与夜间睡眠最低血氧饱和度呈明显的正相关(r=0.40,P<0.005)。结论:重度OSAS患者日间清醒状态下也存在着不同程度的缺氧,月缺氧程度与OSAS病情相关。日间血氧越低,夜间低氧血症越重,对机体的危害也越大。更多还原

【Abstract】 Objective: To find out the relationship between daytime blood oxygen level and night hypoxemia in patients with ob-stractive apnca syndrome (OSAS). Meyhods: Daytime arterial blood gas analysis was measured in 12 snoring patients and 67 patients with OSAS (slight moderate: 29, severe: 38). Results: The daytime arterial PaO2 decreased in severe OSAS.There was a significant positive correlation between AHI index and minimum SaQ during sleep at night (r = 0.40, P< 0.005). Conclusion: The degree of hypoxemia is correlated with OSAS state. The lower the blood oxygen in the daytime, the more sevious is hypoxemia at night.更多还原
