摘　　要：目的:分析脉搏血氧饱和度(SpO2)监测的影响因素,为临床更好地应用SpO2监测提供借鉴。方法:回顾性分析某医院中心ICU于2007-01—2009-07期间SpO2监测值与动脉血氧饱和度(SaO2)监测值不符(85例)的影响因素。结果:85例SpO2监测值异常的影响因素主要为SpO2探头位置异常、动作伪差、被检部位低灌注状态、SpO2监测系统异常、被检部位皮肤色泽异常及环境光,其中,SpO2探头位置异常是最多见的影响因素,占29.41%(25/85)。结论:SpO2监测能较好地反映动脉血氧的变化,但其影响因素较多,必须进行相应的干预,提高其准确性。Objective To analyze influencing factors on pulse oxygen saturation（SpO2） monitoring for clinical practice reference.Methods The influencing factors of which SpO2 readings were different from arterial oxygen saturation（SaO2） values of 85 cases in central ICU from January 2007 to July 2009 were analyzed retrospectively.Results The abnormal site of SpO2 probe,movement artifact,low perfusion states,abnormity of SpO2 monitoring system,abnormal skin color and ambient light might all lead the inaccurateness of SpO2 measurements.The primary influencing factor was the abnormal site of SpO2 probe,which took a 29.41%（25/85） proportion.Conclusion SpO2 readings can better reflect the changes in SaO2,but many factors influence SpO2 readings.Appropriate intervention is needed to improve its accuracy.
