What is emphysema?

Emphysema destroys the walls of the alveoli in the lungs, resulting in a loss of surface area available for the exchange of oxygen and carbon dioxide during breathing

6 of 19

What are the symptoms of emphysema?

  • shortness of breath
  • coughing / wheezing
7 of 19

What causes emphysema?

Main cause is long term exposure to airborne irritants such as:

  • tobacco smoke
  • marijuana smoke
  • air pollution
  • manufacturing fumes

Tests for emphysema?

  1. Pulmonary Function Tests: a patient sits inside an enclosed booth and breathes into a tube. the test measures how much air the lungs can cold, how much air remains trapped after exhalation, how rapidly a person can blow air out from their lungs
  2. CT Scan: shows the small pockets of air throughout the lung
  3. Chest X-Ray Scan: shows the patients abnormally large lungs

Solutions to emphysema?

(treatment mainly focuses on treating the shortness of breath)

  1. OXYGEN THERAPY: reduces strain on the heart (typically inhaled through nasal cannula)
  2. LUNG VOLUME REDUCTION SURGERY: surgical removal of large areas of damaged lung
  3. LUNG TRANSPLANT: most drastic of treatments
