Video at a Glance
- This video discusses the pathophysiology of Chronic Obstructive Pulmonary Disease (COPD).
- COPD patients may have chronic bronchitis, emphysema, or both.
- Chronic mucus buildup obstructs the airways and causes chronic bronchitis.
- Emphysema is a disease of lung fibrosis and loss of elastic recoil. The collagen and elastin fibers between the airways are so damaged that they no longer open upon expiration.
- COPD is characterized by progressive dyspnea, chronic cough, and a history of chronic tobacco use.
- To diagnose COPD, clinicians should administer a pulmonary function test.
