Rhonchi are continuous and low-pitched adventitious lung sounds caused by fluids or secretions in the large airways. They often have a snoring, gurgling, or rattle-like quality. They are heard primarily during expiration, but in some patients, rhonchi will also appear during inspiration. Rhonchi will usually clear or alter in sound after coughing.
