Oxygenation and ventilation were studied by invasive and non-invasive methods in 31 critically ill children; the average age was 27.1 +/- 12.6 months (range from 1 to 144 months). All the patients were receiving mechanical ventilation and had arterial catheters. We correlated PtcO2, PtcCO2 and StcO2 with their respective arterial values, when FiO2 was 1.0, 0.6 and 0.4. There was a good correlation (p less than 0.001) in the three values of FiO2, but it was especially significant in 0.4 (r = 0.904 for PaO2 and PtcO2, r = 0.905 for PaCO2 and PtcCO2 and r = 1 for SaO2 and StcO2). We conclude that StcO2 is the most reliable transcutaneous parameter to evaluate oxygenation state in critically ill patients.
采用有创和无创方法对31名危重症儿童的氧合和通气情况进行了研究；平均年龄为27.1±12.6个月（范围为1至144个月）。所有患者均接受机械通气并留置动脉导管。当吸入氧浓度（FiO2）为1.0、0.6和0.4时，我们将经皮氧分压（PtcO2）、经皮二氧化碳分压（PtcCO2）和经皮血氧饱和度（StcO2）与其各自的动脉值进行了相关性分析。在FiO2的三个值中均存在良好的相关性（p<0.001），但在FiO2为0.4时尤为显著（动脉血氧分压（PaO2）与PtcO2的r = 0.904，动脉血二氧化碳分压（PaCO2）与PtcCO2的r = 0.905，动脉血氧饱和度（SaO2）与StcO2的r = 1）。我们得出结论，StcO2是评估危重症患者氧合状态最可靠的经皮参数。
