An abnormal, high-pitched harsh rattling or musical breathing sound made while awake or during sleep. Stridor is caused by partial obstruction and usually occurs when breathing in. It may be due to a swelling in the throat, an inhaled foreign body, or a tumor. In the infant and young child, simple infection can produce the type of stridor commonly known as croup.

If the obstruction is severe and cannot otherwise be relieved rapidly, a temporary opening (tracheostomy) must be made into the windpipe below the obstruction to provide an artificial airway.

Stri"dor (?), n. [L., from stridere to make any harsh, grating, or creaking sound.]

A harsh, shrill, or creaking noise.
