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).
