Small-Airway Obstruction and Emphysema in Chronic Obstructive Pulmonary Disease

Name: Work Video:
Duration: 3 min 30 s
Description: The major sites of obstruction in chronic obstructive pulmonary disease (COPD) are small airways (<2 mm in diameter). We wanted to determine whether there was a relationship between small-airway obstruction and emphysematous destruction in COPD.
