Table and Figure Legends
Table 1. Characteristics of the infants diagnosed with RSV-induced acute bronchiolitis
a: median (first quartile, third quartile), b: from Reference No. 19.
Table 2. Results of the analyses of parameters of the breath sound spectrum of infants diagnosed with RSV-induced acute bronchiolitis
a: median (first quartile, third quartile), b: Wilcoxon’s signed-rank test. Bold letters represent values with a significant difference.
Table 3. Relationship between parameters of the breath sound spectrum and clinical factors of infants diagnosed with RSV-induced acute bronchiolitis
a: Pearson’s correlation coefficient. Bold letters represent values with a significant difference.
Figure 1. A sound spectrogram of a patient with RSV-induced acute bronchiolitis and normal infant
Spectrograms of a patient with RSV-induced acute bronchiolitis; the acute phase, the recovery phase and a seven-month-old health infant are shown. After a Fourier analysis, the vertical axis showing the frequency in Hz and the horizontal axis showing time. The sound intensity of the breath sounds is indicated by the color. Ex: expiration, Ins: inspiration.
Figure 2. The expiratory sound spectrum in a patient with RSV-induced acute bronchiolitis
The expiratory sound spectrum in a patient with RSV-induced acute bronchiolitis of Figure 1 shows several distinct speaks, similar to a previous report (reference No. 26).
