The linearity and repeatability of measurements of total haemoglobin concentration ([Hb]) and oxygen saturation (So2) by the OSM2 oximeter have been studied. Standard deviations (SD) of measurements from linearity were as follows: [Hb], 4.2 g . litre-1; So2, 1.14 to 1.08% between zero and 100% saturation. Reproducibility by a single operator was within SD 1.1 g . litre-1 for [Hb] and 0.32% for So2, and between operators the means of 5 measurements had SD 0.42 g . litre-1 for [Hb] and 0.19% for So2, suggesting little if any extra variation from one operator to another. Foetal haemoglobin behaved as adult haemoglobin, but carboxyhaemoglobin caused a systematic and reproducible error in So2 measurement, from which HbCO concentration can be derived.
对OSM2血氧计测量总血红蛋白浓度（[Hb]）和血氧饱和度（So2）的线性和可重复性进行了研究。线性测量的标准差（SD）如下：[Hb]为4.2 g·升-1；So2在饱和度为零至100%之间为1.14%至1.08%。单个操作人员的可重复性为[Hb]在SD 1.1 g·升-1以内，So2在0.32%以内，不同操作人员之间5次测量的平均值[Hb]的SD为0.42 g·升-1，So2为0.19%，这表明不同操作人员之间几乎没有额外差异。胎儿血红蛋白的表现与成人血红蛋白相同，但碳氧血红蛋白在So2测量中会导致系统性和可重复性误差，由此可得出HbCO浓度。
