Rhonchi Definition

Rhonchi are continuous low pitched, rattling lung sounds that often resemble snoring. Obstruction or secretions in larger airways are frequent causes of rhonchi. They can be heard in patients with chronic obstructive pulmonary disease (COPD), bronchiectasis, pneumonia, chronic bronchitis, or cystic fibrosis. Rhonchi usually clear after coughing.
