Rhonchi
On this page we provide a definition of rhonchi, including its clinical significance. We then compare it to rales, with audio recordings and text. Finally, we summarize the rhonchi training lessons available on this site.
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.
