The transcutaneous partial pressures of carbon dioxide (PtcCO2) and oxygen (PtcO2) were measured with heated electrodes in 18 hemodynamically stable pediatric ICU patients and these data were compared to simultaneously measured arterial oxygen and carbon dioxide tensions. There was a significant degree of correlation (p less than 0.001) between the skin surface CO2 and O2 and their corresponding arterial tensions. These data defined values for PtcCO2 and PtcO2 indices in the pediatric patient without cardiovascular complications as PtcCO2 index = 1.6 +/- 0.2 and the PtcO2 index = 0.84 +/- 0.18 (PtcCO2 index = PtcCO2/PaCO2 and PtcO2 index = PtcO2/PaO2). The authors found the monitoring of skin surface gases a reliable technique to monitor arterial gas tension in hemodynamically stable patients.
使用加热电极对18名血流动力学稳定的儿科重症监护病房患者测量了经皮二氧化碳分压（PtcCO2）和氧分压（PtcO2），并将这些数据与同时测量的动脉血氧和二氧化碳张力进行比较。皮肤表面的二氧化碳和氧气与其相应的动脉张力之间存在显著的相关性（p小于0.001）。这些数据确定了无心血管并发症的儿科患者的PtcCO2和PtcO2指数值，即PtcCO2指数 = 1.6 +/- 0.2，PtcO2指数 = 0.84 +/- 0.18（PtcCO2指数 = PtcCO2/PaCO2，PtcO2指数 = PtcO2/PaO2）。作者发现，监测皮肤表面气体是一种监测血流动力学稳定患者动脉气体张力的可靠技术。
