Four venous hemoglobin oxygen saturation monitors, two of which provide hemoglobin monitoring, were evaluated and compared to a performance standard (control) during cardiopulmonary bypass (CPB). The CDI 100 Hematocrit/Saturation Monitor, CDI 400, Cobe Hematocrit/Saturation Monitor, and the Baxter Bentley OxySat values were compared to the Radiometer Copenhagen OSM3 Hemoximeter and the Damon International Equipment Company Microbore Centrifuge Hematocrit. The Bentley OxySat meter was found to be the most accurate venous oxygen saturation monitor, with the CDI 100 and the Cobe Hct/Sat monitors correlating closely with the control. Only the CDI 400 failed to correlate with the control. The hematocrit monitors, although useful as trending devices, demonstrated inaccuracies in measurements requiring further refinement.
在体外循环（CPB）期间，对四个静脉血红蛋白氧饱和度监测仪（其中两个还具备血红蛋白监测功能）进行了评估，并与性能标准（对照）进行了比较。将CDI 100血细胞比容/饱和度监测仪、CDI 400、科倍血细胞比容/饱和度监测仪以及百特·本特利血氧饱和度仪（Baxter Bentley OxySat）的值与雷度·米特（Radiometer Copenhagen）OSM3血液气体分析仪以及达蒙国际设备公司微孔离心机血细胞比容进行了比较。结果发现，本特利血氧饱和度仪是最准确的静脉氧饱和度监测仪，CDI 100和科倍血细胞比容/饱和度监测仪与对照密切相关。只有CDI 400与对照不相关。血细胞比容监测仪虽然作为趋势监测设备很有用，但在测量中显示出不准确之处，需要进一步改进。
