Stridor is a high-pitched, predominantly inspiratory sound. It is most commonly associated with acute disorders, such as foreign body aspiration, but can be due to more chronic disorders, such as tracheomalacia.
Stridor is a gasping sound during inhalation resulting from a partial blockage of the throat (pharynx), voice box (larynx), or windpipe (trachea). Stridor is usually loud enough to be heard at some distance. The sound is caused by turbulent airflow through a narrowed upper airway.
