The causes of upper airway obstructions can be acute or chronic. More acute causes of upper airway obstruction include foreign body aspiration, blunt trauma to the neck, infections, and swelling due to allergies or other inflammatory conditions. [3] In children, viral infections such as croup or epiglottitis are frequent causes. [4]
