Chest auscultatory signs in infants presenting to A&E with bronchiolitis.

Background: Anecdotally it has been noted that the traditional chest signs associated with bronchiolitis appear inconsistently in infants clinically diagnosed with bronchiolitis. We wished to explore this more formally.

Objective: The aim of this study was to assess whether the auscultatory chest signs at presentation in infants with bronchiolitis were influenced by age or by the underlying pathogen.
