Rapid Lung Sound Amplitude Measurement by Automated Flow Gated Phonopneumography

  • Chapter

Abstract

Phonopneumography, the graphic display and analysis of lung sounds has enjoyed a slow but progressive increase in use since its introduction in 19701. Problems with the technique when used for the study of vesicular breath sounds arise from the interbreath variability in the sound intensity and the necessity to closely control the flow rate of the subject if intensity measurements are to be meaningful. This has made the comparison of amplitude between different sites very difficult. As a result, in previous studies, relatively few breaths have been analyzed in any one subject and this results in a rather low resolution and highly variable picture of breath sound amplitude in the chest.
