A PCO2 electrode working on the principle of electrical conductivity is described. The calibration curve can be linearized according to the formula G = Go + b square root PCO2. This linearity has been tested in the PCO2 range of 0.93-9.33 kPa (7--70 Torr). For the experiments electrodes are used which have conductivity values of about 50 nS and drifts of maximally 5%/h at a PCO2 of 5.33 kPa (40 Torr). The response time (T90) is about 20 s. The temperature sensitivity is 2.4 nS/1 K between 298 K-310 K. The standard error of the measurements is sigma = 0.33 nS. With these electrodes tissue PCO2 can be measured on the surface of various organs.
本文描述了一种基于电导率原理工作的二氧化碳分压（PCO₂）电极。校准曲线可根据公式G = Go + b√PCO₂进行线性化处理。这种线性关系已在0.93 - 9.33 kPa（7 - 70托）的PCO₂范围内进行了测试。实验使用的电极在5.33 kPa（40托）的PCO₂条件下，电导率值约为50 nS，最大漂移率为5%/小时。响应时间（T90）约为20秒。在298 K - 310 K之间，温度灵敏度为2.4 nS/1 K。测量的标准误差为σ = 0.33 nS。使用这些电极可以在各种器官表面测量组织PCO₂。
