Low pitched wheezes (rhonchi) are continuous, both inspiratory and expiratory, low pitched adventitious lung sounds that are similar to wheezes. They often have a snoring, gurgling or rattle-like quality.
Rhonchi occur in the bronchi. Sounds defined as rhonchi are heard in the chest wall where bronchi occur, not over any alveoli. Rhonchi usually clear after coughing.
