Rhonchi are low-pitched sounds that may occur throughout the respiratory cycle. They have a snoring, gurgling or rattle-like quality, and often characterized by secretions within the large airways. Sounds defined as rhonchi are heard in the chest wall where bronchi occur, not over any alveoli. Rhonchi can be heard in a wide variety of pathologies, any of which cause increased secretions, such as in cystic fibrosis, pneumonia, bronchitis, pulmonary edema, or emphysema. Rhonchi usually clear after coughing.
