Two in-line oxygen saturation monitors, the CDI 100 and OxySat II, were evaluated in the clinical setting. Eighty-seven venous blood samples were drawn during 20 elective cardiopulmonary bypass procedures. Monitor readings were compared to OSM III co-oximeter values. The results revealed that saturation (%) determination was biased, -3.16 +/- 2.21 SD for the CDI 100 and -0.34 +/- 2.17 SD for the OxySat II. Hemoglobin (g/dl) and hematocrit (%) measurement, available only for the CDI 100, resulted in a bias of +5.54 +/- 5.68 SD and +1.94 +/- 1.78 SD, respectively. It was concluded that both monitors operated within clinically acceptable limits, with a more favorable outcome for the OxySat II.
在临床环境中对两款串联式血氧饱和度监测仪CDI 100和OxySat II进行了评估。在20例择期体外循环手术过程中采集了87份静脉血样本。将监测仪读数与OSM III血氧计的值进行比较。结果显示，饱和度（%）测定存在偏差，CDI 100为-3.16±2.21标准差，OxySat II为-0.34±2.17标准差。仅CDI 100可进行血红蛋白（g/dl）和血细胞比容（%）测量，其偏差分别为+5.54±5.68标准差和+1.94±1.78标准差。得出的结论是，两款监测仪均在临床可接受的范围内运行，OxySat II的结果更理想。
