What is pulmonary emphysema?
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 and results in permanent "holes" in the tissues of the lower lungs.
Pulmonary emphysema is part of a group of lung diseases called chronic obstructive pulmonary disease (COPD). COPD lung diseases cause airflow blockage and breathing problems. The two most common conditions of COPD are chronic bronchitis and emphysema.
What are the symptoms of pulmonary emphysema?
Symptoms may be slightly different for each person. The following are the most common symptoms for pulmonary emphysema.
Early symptoms of pulmonary emphysema may include:
- Shortness of breath (most common symptom), which gets worse with activity
- Rapid breathing
- Sputum production
Other symptoms may include:
- Fatigue (extreme tiredness)
- Over-inflation of the lungs
- Sleep problems
- Heart problems
- Weight loss
The symptoms of pulmonary emphysema may look like other lung conditions or health problems. See a healthcare provider for a diagnosis.
How is pulmonary emphysema diagnosed?
Along with a complete medical history and physical exam, your healthcare provider may request:
Pulmonary function tests (PFTs)
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 assess lung function. Spirometry, the evaluation of lung function with a spirometer, is one of the simplest, most common PFTs and may be used to:
Determine how well the lungs receive, hold, and move air
- Look for lung disease
- See how well treatment is working
- Determine the severity of a lung disease
- Find out whether the lung disease is restrictive (decreased airflow) or obstructive (disruption of airflow)
Peak flow monitoring (PFM)
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 and can be measured by a PFM. This measurement is very important in evaluating 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.
