The reliability of pulse oximetry and transcutaneous oxygen tension (tcPO2) was investigated in hypoxemic neonates and older infants with chronic hypoxemia due to bronchopulmonary dysplasia (BPD). It was found that during severe hypoxemia (tcPO2 less than 40 mmHg and saturation less than 80%) pulse oximetry showed a better correlation with arterial saturation than tcPO2 with arterial oxygen tension. During mild hypoxemia and normoxemia (tcPO2 40-90 mmHg and saturation 80-95%) tcPO2 and pulse oximetry both showed a good correlation with arterial values. Above 95% saturation and a corresponding tcPO2 of 70-120 mmHg, the correlation between arterial and transcutaneous PO2 was better than that between pulse oximetric and arterial saturation. Computer recording and analysis of tcPO2 and pulse oximetry improves the quality of both noninvasive oxygenation parameters in older infants with BPD.
在患有支气管肺发育不良（BPD）导致低氧血症的低氧新生儿和大龄婴儿中，对脉搏血氧饱和度测定法和经皮氧分压（tcPO2）的可靠性进行了研究。结果发现，在严重低氧血症期间（tcPO2低于40 mmHg且饱和度低于80%），脉搏血氧饱和度测定法与动脉血氧饱和度的相关性优于tcPO2与动脉氧分压的相关性。在轻度低氧血症和正常氧合期间（tcPO2为40 - 90 mmHg且饱和度为80 - 95%），tcPO2和脉搏血氧饱和度测定法与动脉值均显示出良好的相关性。饱和度高于95%且相应的tcPO2为70 - 120 mmHg时，动脉与经皮PO2之间的相关性优于脉搏血氧测定值与动脉血氧饱和度之间的相关性。对tcPO2和脉搏血氧饱和度测定法进行计算机记录和分析，可提高患有BPD的大龄婴儿两种无创氧合参数的质量。
