These normal breath sounds are harsh and sound like air is being blown through a pipe.
Tracheal
These normal sounds are loud and high in pitch with a short pause between inspiration and expiration; expiratory sounds last longer than inspiratory sounds.
Bronchial
These normal breath sounds are softer than bronchial sounds, but have a tubular quality. The sounds are about equal during inspiration and expiration
Bronchovesicular
These normal breath sounds are soft, blowing, or rustling sounds; normally heard throughout most of the lung fields and heard throughout inspiration, continue without pause through expiration and then fade away.
Vesicular
Viral disease of the lower respiratory tract where inflammation causes obstruction of the small respiratory airways.
Bronchiolitis
“bronchitis in little people”
Bronchiolitis - typical age
less than 3 years
Bronchiolitis - typical pathogen
RSV (50%)
Bronchiolitis - signs and symptoms (4)
o URI symptoms lasting several days
o increasing respiratory distress
o moderate fever
o palpable liver and spleen (hyperinflated lungs)
