A microprocessor-based system was developed for the measurement and on-line calculation of values and derivatives of expiratory variables and their response to exercise. The system accepts analog signals from gas analysers, ECG electrodes and flow transducer, digitizes these signals, calculates values of required parameters and presents results on a video display. The system offers the user various options of logging and data processing. Plots of the values of calculated parameters versus exercise time and correlation between variables can be easily produced by the system. A mass storage unit was available with the system to enable the storage of calculated variables for off-line analysis. Hardcopy of displayed results and plots can be provided by the system.
开发了一种基于微处理器的系统，用于测量和在线计算呼气变量的值及其导数，以及它们对运动的反应。该系统接收来自气体分析仪、心电图电极和流量传感器的模拟信号，将这些信号数字化，计算所需参数的值，并在视频显示器上显示结果。该系统为用户提供了各种记录和数据处理选项。系统可以轻松生成计算参数值与运动时间的关系图以及变量之间的相关性。该系统配备了大容量存储单元，以便存储计算出的变量用于离线分析。系统可以提供显示结果和图表的硬拷贝。
