Pathophysiology: break down of elastin (affect alveoli and alveolar vessels)
- High Lung Compliance
- Increase FRC Body Plethysmography
- Decreased Expiratory Airflows ‣
- Decreased Diffusion DLCO (75% - 125%)
S/S:
- Dyspnea
- Cachetic
- Normal PaO2, PaCO2
- Normal V/Q ratio
Prognosis:
- Less exacerbation
