Objective To evaluate and differentiate the spectral characteristics of the breath sounds in patients with asthmatics and chronic asthmatic bronchitis during acute episode Methods The breath sounds in 10 patients with asthmatics and 8 patients with chronic asthmatic bronchitis during acute episode were recorded by using microphone and computer and analyzed with fast fourier transform (FFT). Results No difference of the expiratory frequency and intensity was found between the wheezes in patients with asthmatics and chronic asthmatic bronchitis during acute episode ( P >0 05) However, during acute episode the inspiratory frequencies in patients with chronic asthmatic bronchitis was significantly lower than that in asthmatics ( P <0 05 or P <0 01) Conclusion The analysis of the breath sounds in patients with asthmatics and chronic asthmatic bronchitis during acute episode may be helpful for their diagnosis and differential diagnosis
