COPD - Supporting structures of lungs are destroyed by repeated infection, inflammatory responses, and remodeling
- Air goes in easily, but remains in the lungs
- “Air Trapping” causes hyper-inflation of the lungs
- Bronchioles tend to collapse
- This increase in residual capacity (the extra air left in the lungs) changes the appearance of the chest and gives it what classic type of appearance? ”Barrel – chested “ (more so with emphysema).
