Arterial oxygen pressures were compared with oxygen pressures measured transcutaneously with the aid of "TCM 1", an apparatus manufactured by Radiometer. At normal oxygen partial pressures the transcutaneously determined values for pO2 ran parallel with those measured intraarterially, but were on average 10.7% lower than the latter. In cases where oxygen partial pressures were above or below normal the figures did not agree. In these conditions, therefore, determinations in the arterial blood cannot be dispensed with. Halothane in concentrations of 0.3-0.5% and nitrous oxide (66%) in the inspired air did not affect the transcutaneous determination of pO2, but the method failed during surgical electrocoagulation.
将动脉血氧分压与借助Radiometer公司生产的“TCM 1”设备经皮测量的氧分压进行了比较。在正常氧分压情况下，经皮测定的pO2值与动脉内测量值平行，但平均比后者低10.7%。在氧分压高于或低于正常的情况下，数值不一致。因此，在这些情况下，不能省略动脉血的测定。吸入空气中浓度为0.3 - 0.5%的氟烷和一氧化二氮（66%）不影响经皮测定pO2，但在手术电凝期间该方法失败。
