Abstract

Способ диагностики бронхообструктивного синдрома путем регистрации дыхательных шумов с помощью датчика с последующей их обработкой на компьютере, отличающийся тем, что регистрируют респираторные шумы в точке над трахеей в течение 20 с, запись подвергают быстрому преобразованию Фурье, затем полученный спектр респираторных шумов преобразовывают с помощью формулыгде Y - нормированная амплитуда гармоник,x - нормированная частота,c и d - коэффициенты, вычисляемые методом наименьших квадратов, и при значении с от 45 до 120 одновременно с величиной d>0,5 диагностируют бронхообструктивный синдром.A method for diagnosing bronchial obstructive syndrome by recording respiratory noise using a sensor and then processing it on a computer, characterized in that respiratory noise is recorded at a point above the trachea for 20 seconds, the recording is subjected to fast Fourier transform, then the resulting spectrum of respiratory noise is converted using the formula where Y is the normalized harmonic amplitude, x is the normalized frequency, c and d are the coefficients calculated by the least squares method, and with values from 45 to 120 simultaneously with the value d> 0,5 diagnosed bronchial obstruction.
