Expiratory stridor is usually from the lower respiratory tract and gives rise to a prolonged expiratory wheeze. It is most commonly associated with acute asthma or acute infective tracheobronchitis. Biphasic stridor is usually due to obstruction or disease of the tracheobronchial airway and distal lungs. Summary box 52.8 Stridor /uni25CF /uni25CF /uni25CF /uni25CF /uni25CF /uni25CF
