摘　　要：目的：评价3种国产脉搏血氧饱和度仪Nellcor测量模式探头DS-100A的准确度。方法：当由标准监护仪测得的Sp02分别为100％（Tl状态）、92％（T2状态）、85％（B状态）、78％（rf4状态）、70％（T5状态）时，记录5个相应状态10例成年健康志愿者分别由Lendeavour12（结果为L组）、iTM（结果为I组）与PeneViewT1（结果为P组）3种患者监护仪DS-100A探头监测的SpO2数值，同时监测动脉血氧饱和度值（SaO2），计算SpO。与SaO2的差值，评价3组仪器探头测量SpO2的准确度。结果：当SpO2在70％～100％范围内时，L、I、P组的SpO：准确度均在标准范围内；I组准确度最高，其次为L、P组。对5个状态的3组SpO2值进行两两比较发现，L状态时，P组SpO：值明显高于L组（P〈0．05）。结论：3种型号脉搏血氧饱和度仪Nellcor模式DS-100A探头所测得的SpO2值都是准确有效的，iTM型号的准确度最高。Objective To evaluate the accuracy of DS-100A probes under Nellcor measurement mode in three types of domestic pulse oximeters. Methods Ten healthy volunteers and a standard monitor were involved in the research, with standard pulse oxygen saturation （SpO2） kept 100% （T0, 92% （T2）, 85% （T3）, 78% （T4） and 70% （T5）. The SpO2 values were detected with the DS-100A probes of Lendeavour 12 monitor, iTM monitor and PeneView T1 monitor, with the results put into group L, I and P respectively. The arterial oxygen saturation（SaO2） and its difference with SpO2 were determined to evaluate the accuracy of the three probes. Results When SpO2 ranged from 70% to 100%, all the three groups had the accuracy acceptable, with the one of group 1 the highest, followed by groups L and P. The comparative study showed that the SpO2 value of group P was significantly higher than that of group L at stage T3, with P〈0.05. Conclusion The DS-100A probes of the three monitors are all accurate and effective for measuring Sp02, with iTM monitor gifted with highest accuracy.
