For registration of oxygen tension fields in peripheral muscle a microcomputer based system was designed on the M6800 microprocessor. The system was designed to record the signals from a multiwire oxygen electrode, MDO, which is a multiwire electrode for measuring oxygen on the surface of an organ. The system contained patient safety isolation unit built on optocopplers and the upper frequency limit was 0.64 Hz. Collected data were corrected for drift and temperature changes during the measurement by using pre- and after calibrations and a linear compensation technique. Measure drift of the electrodes were proved to be linear and thus the drift could be compensated for. The system was tested in an experiment on pig. To study the distribution of oxygen statistically mean, standard deviation, skewness and curtosis were calculated. To see changes or differences between histograms a Kolmogorv-Smirnov test was used.
为了记录外周肌肉中的氧张力场，设计了一种基于M6800微处理器的微机系统。该系统旨在记录来自多线氧电极MDO的信号，MDO是一种用于测量器官表面氧气的多线电极。该系统包含基于光耦合器构建的患者安全隔离单元，上限频率为0.64Hz。在测量过程中，通过使用测量前后的校准和线性补偿技术，对采集的数据进行漂移和温度变化校正。电极的测量漂移被证明是线性的，因此可以对漂移进行补偿。该系统在猪身上进行了实验测试。为了统计研究氧气的分布，计算了均值、标准差、偏度和峰度。为了观察直方图之间的变化或差异，使用了柯尔莫哥洛夫-斯米尔诺夫检验。
