Microprocessor-based system for on-line analysis of respiratory responses to exercise
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.
