For heart sounds listen to the synthetic sound while reviewing this lesson.
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.
