Determination of the oxygen saturation (SaO2) was carried out on 47 patients employing five pulse oxymeters. Measurements with Criticare CSI 501 (Simonsen & Weel), Criticare CSI 502 (Simonsen & Weel), Nellcor N 100 (Dräeger), Satlite (Datex) and Novametrix 500 (Vickers) were compared with arterial blood gas analyses with Radiometer ABL 3 (Radiometer, Copenhagen). Statistical calculation of the agreement with the pulse oxymetric and the invasive measurements were performed by the method recommended by Bland & Altman. The precision profiles for the pulse oxymeters varied from 1.84 to 2.25 (CV%) and the accuracy profiles from -0.90 to 1.44%. All of the apparatuses fulfilled the specifications made by the manufacturs. All were considered to be suitable and reliable for monitoring of decreases in oxygen saturation during and after operation.
使用五台脉搏血氧仪对47名患者进行了血氧饱和度（SaO2）测定。将Criticare CSI 501（Simonsen & Weel）、Criticare CSI 502（Simonsen & Weel）、Nellcor N 100（德尔格）、Satlite（Datex）和Novametrix 500（维克斯）的测量结果与Radiometer ABL 3（Radiometer，哥本哈根）的动脉血气分析结果进行了比较。按照Bland & Altman推荐的方法对脉搏血氧测定法与有创测量结果的一致性进行了统计计算。脉搏血氧仪的精密度曲线在1.84%至2.25%（变异系数）之间，准确度曲线在-0.90%至1.44%之间。所有仪器均符合制造商规定的规格。所有仪器都被认为适用于监测手术期间和术后的血氧饱和度下降情况且可靠。
