Physical Diagnostic (Adventitious Breath Sounds)

The term “adventitious” breath sounds refers to extra or additional sounds that are heard over normal breath sounds. Sources differ as to the classification and nomenclature of these sounds, but most examiners commonly use the following terms to describe adventitious breath sounds.



* crackles (or rales)
* wheezes (or rhonchi)
* pleural friction rubs
* stridor
Detection of adventitious sounds is an important part of the respiratory examination, often leading to diagnosis of cardiac and pulmonary conditions.
