Question

Quizplus · Accepted Answer

Croup, the most common cause of upper airway obstruction in children, is a viral infection that causes subglottal mucosal edema of the larynx and trachea. The illness begins with an upper respiratory tract infection, progressing to an inspiratory stridor and a "barky" cough after several days. Stridor is a harsh sound caused by the vibration of air through a narrowed upper airway. The obstruction is occasionally severe enough to require an artificial airway.
