用赫氏电池校准的金氧阴极被用来监测小鼠睾丸中的氧浓度。描述了电极的校准技术，以及在小鼠呼吸不同含氧量(从5%到100%)的混合气体中进行的测量。小鼠被发现在呼吸这些混合物时至少存活了四分钟，当呼吸10%或5%的氧气时，组织缺氧水平低于呼吸纯氮气时所能达到的水平。结果表明，氧参数可用较大的电极测量，并与肺泡氧分压的变化直接相关。
Gold oxygen cathodes, calibrated against a Hersch cell, have been used to monitor oxygen concentrations in the mouse testis. The technique of calibration of the electrodes is described, together with measurements made in mice breathing gas mixtures with different oxygen contents, from 5 to 100%. Mice were found to survive for at least four minutes breathing these mixtures, and the level of tissue hypoxia produced when breathing 10 or 5% oxygen is lower than can be achieved by breathing pure nitrogen. The results show that an oxygen parameter, with dimen- sions of oxygen concentration, may be measured with relatively large electrodes, and is related directly to variations in alveolar pO2.
