Wheezing is the symptomatic manifestation of any disease process which causes airway obstruction. It is a musical, high pitched, adventitious sound generated anywhere from the larynx to the distal bronchioles during either expiration or inspiration.

Wheeze is the most common symptom of asthma in children under 5, but it does not always sound the same 1. Furthermore, children are more likely to require urgent health care than asthma sufferers of any age.2 The identification of wheeze is important for the asthmatic symptom control in children and to prevent attacks 1,3. However, wheeze is a subjective sound and can be described in many ways4. The conceptual understandings of the sound of wheeze for parents are different from epidemiology definitions5.

Moreover, poorly managed asthma can result in reduced quality of life for patients, a more regular need for healthcare resources, and substantial costs to public health services4,6.
