Airspaces - Study guides, Class notes & Summaries

Emphysema Pathophysiology ~~~ Emphysema is a pathologic diagnosis defined by permanent enlargement of airspaces distal to the terminal bronchioles. This leads to a dramatic decline in the alveolar surface area available for gas exchange. Furthermore, loss of alveoli leads to airflow limitation by 2 mechanisms. First, loss of the alveolar walls results in a decrease in elastic recoil, which leads to airflow limitation. Second, loss of the alveolar supporting structure leads to airwa...
