WebMay 23, 2016 · Now in emphysema you have decreased alveolar pressure for the volume. So say the alveolar pressure is 28 and the intrapleural pressure created is 25 again. So now it is still positive at the alveoli but then we get to the terminal bronchioles say and all of a sudden the pressure is 23 and the intrapleural is still 25. WebWhat is the cause of less elastic recoil in emphysema? 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 airway narrowing, which further limits airflow. Emphysema has 3 morphologic patterns: Centriacinar.
