rhonchus[rong´kus] (pl. rhon´chi) (L.)
a continuous sound consisting of a dry whistlelike noise with a lower pitch than that of a wheeze, produced in the throat or bronchial tube due to a partial obstruction.
[rong′kəs] pl. rhonchi
Etymology: Gk, rhonchos, snore
an abnormal sound heard on auscultation of an airway obstructed by thick secretions, muscular spasm, neoplasm, or external pressure. The continuous rumbling sound is more pronounced during expiration and characteristically clears on coughing, whereas gurgles do not.
A low-pitched wheezing, snoring, or squeaking sound heard during auscultation of the chest of a person with partial airway obstruction. Mucus or other secretions in the airway, bronchial hyperreactivity, or tumors that occlude respiratory passages can all cause rhonchi.
