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).

Famous quotes containing the word obstruction:
“The short lesson that comes out of long experience in political agitation is something like this: all the motive power in all of these movements is the instinct of religious feeling. All the obstruction comes from attempting to rely on anything else. Conciliation is the enemy.”
—John Jay Chapman (1862–1933)
