夜间血氧监测在诊断慢性心力衰竭伴睡眠相关呼吸障碍中的应用

Diagnostic value of nocturnal oximetry in theSRBD patients of CHF

目的评价夜间非吸氧状态下脉搏血氧仪血氧监测在慢性心力衰竭（CHF）患者中诊断睡眠相关呼吸障碍（SRBD）的意义。方法已经诊断CHF的76例患者进行夜间非吸氧状态下脉搏血氧仪血氧监测；同步进行实验室多导睡眠图（PSG）监测；对脉搏血氧仪血氧监测结果和PSG血氧测定的结果进行可靠性比较。结果CHF患者夜间非吸氧状态下脉搏血氧仪血氧监测结果与PSG的血氧饱和度变化一致；SpO2能够很好地反映CHF患者合并SRBD，并且与SRBD病隋轻重程度有一定相关性。结论脉搏血氧仪血氧监测是CHF患者简易的筛查SRBD的方法。

Objective To explore the diaggnotic value of nocturnal oximetry in the SRBD patients of CHF. Methods The peripheral SpO2 and PSG were clinically monitored synchronously in 76 CHF patients. At dawn of the second day, compared with nocturnal oxygen saturation monitor and result of PSG . Results The results between peripheral SpO2 and PSG in CHF patients were very concordant. SpO2 can well reflect the existence of SRBDin CHF patients , and there is significant correlation between SpO2 and the severity of SRBD. Conclusion Nocturnal oximetry is a simple and easy method to screening the SRBD patients of CHF.
