Airway obstruction is a respiratory problem caused by increased resistance in the bronchioles (usually from a decreased radius of the bronchioles) that reduces the amount of air inhaled in each breath and the oxygen that reaches the pulmonary arteries. It is different from airway restriction (which prevents air from diffusing into the pulmonary arteries because of some kind of blockage in the lungs).

Airway obstruction can be caused by obvious physical obstruction, such as choking or due to a swollen epiglottis in epiglottitis. It can also be caused by less obvious causes of airway compromise such as chronic obstructive pulmonary disease, pneumonia and pulmonary edema. A high index of suspicion needs to be maintained when a person presents with signs of infection and upper airway obstruction, as epiglottitis and peritonsillar abcess can cause rapid cardiorespiratory compromise.

Inability to relieve the obstruction can cause:

• Brain damage
• Breathing failure
• Death

Prompt treatment is often successful. However, the condition is dangerous and may be fatal, even if treated.
