Transcutaneous PO2 (PTCO2) (Radiometer electrode heated to 44 degrees C) was compared to arterial PO2 (PaO2) in 19 infants with bronchopulmonary dysplasia: 12 infants were tested once, at the mean postnatal age of 14 weeks (range 4-43 weeks), the other 7 infants were studied longitudinally from 5 weeks (range 2-8 weeks) to 12 weeks (range 6-18 weeks) of postnatal age. The protocol was standardized: measurement during behavioral stage 1, using a peripheral arterial line. Twenty-eight comparisons between PTCO2 and PaO2 were obtained. PTCO2 was significantly related to PaO2 [PTCO2 (mmHg) = 0.81 PaO2 + 5.2, r = 0.73, p less than 0.01]. The mean difference PTCO2 - PaO2 was -7.2 mmHg (range: -34.5 to + 33); in the studied age range the PTCO2 - PaO2 was not significantly related to postnatal age (r = -0.24; p greater than 0.1).
对19例支气管肺发育不良的婴儿进行经皮氧分压（PTCO2）（辐射计电极加热至44摄氏度）与动脉氧分压（PaO2）的比较：12例婴儿在出生后平均14周（范围4 - 43周）时进行了一次测试，另外7例婴儿从出生后5周（范围2 - 8周）至12周（范围6 - 18周）进行了纵向研究。研究方案标准化：在行为阶段1期间使用外周动脉导管进行测量。共获得28次PTCO2与PaO2的比较结果。PTCO2与PaO2显著相关[PTCO2（mmHg）= 0.81×PaO2 + 5.2，r = 0.73，p < 0.01]。PTCO2 - PaO2的平均差值为 - 7.2 mmHg（范围：-34.5至+ 33）；在研究的年龄范围内，PTCO2 - PaO2与出生后年龄无显著相关性（r = -0.24；p > 0.1）。
