Emphysema is a chronic lung condition in which the air sacs (alveoli) may be:
Overinflation of the air sacs is a result of breakdown of the walls of the alveoli. It causes a decrease in respiratory function and breathlessness. Damage to the air sacs is irreversible. It results in permanent holes in the tissues of the lower lungs.
Emphysema is part of a group of lung diseases called COPD. COPD lung diseases cause airflow blockage and breathing problems. The two most common conditions of COPD are chronic bronchitis and emphysema.
Emphysema does not develop suddenly, but very slowly over time. It’s caused by:
Symptoms may be slightly different for each person. The following are the most common symptoms for emphysema.
Early symptoms of emphysema may include:
Other symptoms may include:
The symptoms of emphysema may look like other lung conditions or health problems. See a healthcare provider for a diagnosis.
Along with a complete medical history and physical exam, your healthcare provider may request pulmonary (lung) function tests. These tests help measure the lungs’ ability to exchange oxygen and carbon dioxide. The tests are usually done with special machines into which you breathe. They may include:
A spirometer is a device used to check lung function. Spirometry is one of the simplest, most common tests. It may be used to:
This device measures how fast you can blow air out of your lungs. Cough, inflammation, and mucus buildup can cause the large airways in the lungs to slowly narrow. This slows the speed of air leaving the lungs. This measurement is very important in seeing how well or how poorly the disease is being controlled.
These are done to check the amount of carbon dioxide and oxygen in the blood.
This test takes pictures of internal tissues, bones, and organs.
This test uses a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body. CT can show details like the width of airways in the lungs and the thickness of airway walls.
This test is done on the material that is coughed up from the lungs and into the mouth. A sputum culture is often used to see if an infection is present.
This is a test that records the electrical activity of the heart, shows abnormal rhythms (arrhythmias), and can help find heart muscle damage.
The goal of treatment for people with emphysema is to live more comfortably with the disease, control symptoms, and prevent the disease from getting worse, with minimal side effects. There is no way to repair or regrow the damaged lung tissue.
