abstract

  • Aim. The present work was aimed at development of the technique for computerized diagnosis of pediatric bronchial asthma based on analysis of respiratory noises. Materials and methods. Computerized system for respiratory noise recording was used to receive sound signals from three points located in the mouth, above the trachea and above the right lung (on the front surface of the chest) in 51 pupils (aged 11, 2±3, 2 years) suffering from bronchial asthma and in 22 healthy volunteers (aged 11, 6±2, 5 years). Record of patient's respiratory noises was fulfilled using electronic device with subsequent computational investigation of specific spectral characteristics of this sound. The technique for computerized diagnosis, permitting to perfect the possibilities of respiratory noise processing by means of fast Fourier transport (FFT), is offered in the paper. The suggested technique …
