Peculiarities of spectral tussography in patients with bronchial asthma and diabetes

Abstract

Growing number of bronchial asthma patients and progressive morbidity of diabetes make actual the investigation of their combined course. Structural and functional lung changes In bronchial asthma influence the frequency range of cough sounds and the diabetes joint reinforces them. Spectral tussography allows to expand our conception of bronchial asthma alone and bronchial asthma against the diabetes background clinical features. Based on the analysis of the tussographic data obtained, the prevalence of a low frequency range over medium and high ones and also the extension of cough duration were found; those changes were more significant in the case of the combined pathology. Repeated researches showed a lessening of the low frequency range portion and an insignificant reduction of cough duration. Thus, the spectral tussography method can be applied for an assessment of the treatment efficacy so that it makes an image of structural and functional changes in bronchopulmonary system due to the treatment.
