pO2 was measured transcutaneously (commercially available Clark Electrode, Bioelectronics Roche) with two different electrode temperatures in new born infants. The correlation between paO2 (arteria radialis) and ptcO2 was bad (r= 0,74) with electrode temperature of 42 degrees C. When the electrode was heated to 44 degrees C there was a very good correlation (r= 0,969) in 80 simultaneous measurements of paO2 (umbilical arterial catheter) and ptcO2. The mean values and standard deviations of pO2 values in hypoxic, normoxic and hyperoxic states are very similar: hypoxic: paO2 34,3 "/- 7,9, ptcO2 35,2 +/- 14,0, normoxic: paO2 78,7 +/- 14,3 ptcO2 78,8 +/- 16,7, hyperoxic: paO2 141,8 +/- 37,1, ptcO2 134,4 +/- 40,8 mmHg). The specific advantage of transcutaneous measurements is the trend registration for hours. With electrodes temperatures of 44 degrees C however, there is a risk of superficial burns if the electrode is attached to the identical site for 6 hours or more.
在新生儿中，使用两种不同的电极温度经皮测量氧分压（pO2）（市售的克拉克电极，罗氏生物电子公司）。当电极温度为42摄氏度时，动脉血氧分压（paO2，桡动脉）与经皮氧分压（ptcO2）之间的相关性较差（r = 0.74）。当电极加热到44摄氏度时，在80次同时测量脐动脉导管paO2和ptcO2时，两者具有非常好的相关性（r = 0.969）。低氧、正常氧和高氧状态下pO2值的平均值和标准差非常相似：低氧：paO2 34.3±7.9，ptcO2 35.2±14.0；正常氧：paO2 78.7±14.3，ptcO2 78.8±16.7；高氧：paO2 141.8±37.1，ptcO2 134.4±40.8（mmHg）。经皮测量的特殊优势在于能够记录数小时的变化趋势。然而，当电极温度为44摄氏度时，如果电极在同一部位附着6小时或更长时间，存在皮肤表面烧伤的风险。
