THE REAL-TIME VIZUALIZATION OF PNEUMOGRAM SIGNALS


The real-time visualization of pneumogram signals is described in this contribution. The device created provides simultaneous measurement of pneumogram and voice. The sampled signals are transmitted to PC software in real time via USB bus, which makes it possible to show the curves from the sampled signals in real-time. In addition, data archiving and printing functions are integrated into the software. Since pneumography is one of the oldest methods to provide information about the technique of respiration, it will be possible for doctors in phoniatric practice to use the created device and programmed application for patient diagnosis. Listed in the results is an example of the recordings acquired from the designed device.

Keywords:
pneumography, pneumogram, phoniatry, diagnostics, real-time signal processing, visualization
