So let's wrap up this video. Emphysema is a chronic condition and it causes destruction of
the alveolar walls. Remember that's different than chronic bronchitis which is gunked up,
emphysema is blown up. Now because of this blown-up walls, emphysema causes air trapping
and patients can minimize the effect of this with pursed lip breathing that extends the exhale
time. Now in extensive COPD, the lungs become hyperinflated and they have chronic air
trapping and that's why they become hyperinflated and they can develop a barrel chest.
They're just as wide as they are deep. Now treatment options include oxygen, bronchodilators,
corticosteroids, good hydration and nutrition, energy conservation, and in rare cases lung
volume reduction surgery. Remember, there are 4 things you want to specifically watch for for
late-stage complications. That's pulmonary hypertension, cor pulmonale, recurrent respiratory
infections, and chronic respiratory failure. Thank you for watching our video today.
