This wheezing and coarse crackles were recorded over the right posterior lower lung of an 8 month old boy with viral bronchiolitis.

The respirosonogram provides a visual representation of the content of the respiratory sound recording. Time is shown on the horizontal and frequency on the vertical axis. Sound intensity is indicated on a color scale, ranging from red (loud) over yellow and light green (medium) to dark green and gray (low). The breathing signal from Respitrace [RESP] is plotted at the top (inspiration [I] = up, expiration [E] = down).
