We studied the effect of hypotension and of electrode temperature (41 degrees C to 44 degrees C) on the relation of skin surface PCO2 (Roche prototype) to arterial PCO2 in 24 sick neonates of 690 to 3,500 gm with systolic blood pressures of 5 to 70 mm Hg. PsCO2 closely correlated with PaCO2. The standard error of estimating PaCO2 from PsCO2 was 3.02 torr at 44 degrees C, 3.20 torr at 43 degrees C, and 3.57 torr at 41 degrees C. The pH (6.89 to 7.61), body temperature (33.5 to 38.1 degrees C), hematocrit (0.28 to 0.65), scleredema, or treatment with tolazoline did not affect the relation of PsCO2 to PaCO2. PsCO2 grossly exceeded the predicted value at systolic blood pressures below 15 mm Hg, irrespective of electrode temperature.
我们研究了低血压和电极温度（41摄氏度至44摄氏度）对24例体重690至3500克、收缩压5至70毫米汞柱的患病新生儿皮肤表面PCO2（罗氏原型）与动脉PCO2关系的影响。皮肤表面PCO2（PsCO2）与动脉PCO2（PaCO2）密切相关。在44摄氏度时，根据PsCO2估算PaCO2的标准误差为3.02托，43摄氏度时为3.20托，41摄氏度时为3.57托。pH值（6.89至7.61）、体温（33.5至38.1摄氏度）、血细胞比容（0.28至0.65）、硬肿症或妥拉唑啉治疗均不影响PsCO2与PaCO2的关系。无论电极温度如何，当收缩压低于15毫米汞柱时，PsCO2明显超过预测值。
