Bronchophonography in a complex diagnostics of bronchial asthma in children
Abstract
Bronchophonography (BPG) is a functional diagnostic method for the breathing pattern assessment. It is based on an analysis of frequency-peak parameters of the breathing sound spectrum. The method allows to fix a temporary acoustic curve arising during the respiration with the subsequent mathematical processing of the data. The breathing sound fluctuation amplitude ranges within 0-12.4 kHz that permits to calculate an acoustic breathing work equivalent the lung work aimed to the breathing. Hardware-software complex displays the fixed breathing sounds and evaluates their parameters not revealed during the physical examination. The highfrequency range (5.0-12.4 kHz) corresponds to wheezing.
We examined 76 bronchial asthmatic children aged from 1 to 14 years. The control group involved 48 children with no lung pathology. The examination included clinical, spirography and BPG testing.
The BPG method contributes to the routine lung functional testing and allows evaluating the bronchial asthma severity in children.
