✦ Synopsis

An interactive, real-time, computer-based data acquisition system was designed to obtain data for breathing and exercise entrainment studies. By timing the steps of subjects walking on a treadmill relative to different points in the respiratory cycle (e.g. the beginning and end of inspiration), the relation between gait and ventilation can be followed on a breath-by-breath basis. Accurate establishment of the beginning and end of respiratory events from a pneumotachygraph signal was assured by using tidal volume thresholds for (1) noise, (2) minimum valid volume and (3) minimum duration.
