Differential Diagnosis of Asthma and COPD Based on Multivariate Pulmonary Sounds Analysis.

Objective: Asthma and chronic obstructive pulmonary disease (COPD) can be confused in clinical diagnosis due to overlapping symptoms. The purpose of this study is to develop a method based on multivariate pulmonary sounds analysis for differential diagnosis of the two diseases. Methods: The recorded 14-channel pulmonary sound data are mathematically modeled using multivariate (or, vector) autoregr...
