Emphysema
Emphysema is a chronic obstructive disease of the lungs. The lungs contain millions of tiny air sacs called alveoli. In emphysema the sacs lose their elasticity and air becomes trapped in the sacs. It becomes difficult to expel oxygen-depleted air from the lungs. So the normal exchange of new and used air is diminished.Emphysema is classified as a chronic obstructive pulmonary disease (COPD).
Causes
Emphysema develops due to:
- Smoking cigarettes
- Inhaling toxins or other irritants
- Alpha1-antitrypsin deficiency (A1AD) ? a genetic defect which can cause emphysema at an early age in non-smokers
Risk Factors
A risk factor is something that increases your chance of getting a disease or
condition.
- Smoking cigarettes
- Family members with emphysema
- Exposure to pollutants at work
- History of frequent childhood lung infections
- Age: 50 or older
Symptoms
Early symptoms include:
- Coughing in the morning
- Coughing up clear sputum (mucus from deep in the lungs)
- Wheezing
- Shortness of breath with activity
- Increased shortness of breath
- Rapid breathing
- Choking sensation when lying flat
- Fatigue
- Trouble concentrating
- Increase in chest size
- Increased risk of serious lung infections
- Enlargement of the right chamber of the heart
- Heart failure
Diagnosis
The doctor will ask about your symptoms and medical history, and perform a
physical exam.
Tests may include:
Tests may include:
- Chest x-ray
- CT scan ? a type of x-ray that uses a computer to make pictures of structures inside the chest
- Blood tests assessing the amount of oxygen and carbon dioxide in the blood
- Lung function tests
Treatment
There is no treatment to cure emphysema. Treatment aims to ease symptoms and
improve quality of life.
Treatment includes:
Smoking Cessation
Quitting smoking slows progression of the disease. Doctors consider it the most important aspect of treatment. Smoking cessation programs may include behavior modification and medications to help you gradually taper off cigarettes.
Environmental Management
Limiting the number of irritants in the air may help make breathing easier. Avoid smoke, dust, smog, extreme heat or cold, and high altitudes.
Medication
Medications may be taken by mouth or inhaled. Nebulizers and inhalers deliver drugs directly to the lungs. Drugs for emphysema may work in the following ways:
Oxygen is given to supplement the air taken in by the body. It can increase energy levels and heart and brain function by increasing the amount of available oxygen.
Infection Prevention
Because emphysema makes you prone to flu and pneumonia, doctors recommend an annual flu shot. Be sure to have a pneumococcal vaccine. Avoid being around people who are sick. If you think you are getting the flu, contact your physician. You may need to take an anti-viral medication.
Exercise
Special exercises can strengthen chest muscles and make breathing easier. Physical activity builds endurance and improves quality of life. Follow your doctor's recommendations for activity levels and restrictions.
Breathing Techniques
Special methods of breathing and breathing exercises with and without an incentive spirometer can help bring more air into the lungs and force trapped air out of the lungs.
Nutrition and Fluids
A small number of patients may benefit from surgery. Procedures used to treat emphysema include:

Medication
Medications may be taken by mouth or inhaled. Nebulizers and inhalers deliver drugs directly to the lungs. Drugs for emphysema may work in the following ways:
- Opening the airways
- Relaxing the breathing passages
- Decreasing inflammation
- Helping thin secretions and bring up mucus from the lungs
- Treating lung infections (antibiotics)

Nutrition and Fluids
- Maintain a normal weight. Excess weight causes the lungs and heart to work harder.
- Eat a healthy diet that is low in saturated fat and rich in fruits, vegetable and whole grain foods.
- Eat several small meals during the day. It makes breathing easier.
- Avoid gas-producing foods. An overly full stomach pushes up on the diaphragm, which encroaches on the lungs' space, making it harder to breathe.
- Drink fluids to keep mucus thin.
- Pace your activities.
- Learn relaxation techniques and other methods to manage stress.
- Seek emotional support from professionals, family and friends. Anxiety can increase the rate of respiration, making breathing more strenuous.
A small number of patients may benefit from surgery. Procedures used to treat emphysema include:
- Lung volume reduction surgery
- Lung transplant
Prevention
You can reduce you chances of developing Emphysema by:
- Not smoking
- Avoiding exposure to air pollution or irritants
- Wearing protective gear if exposed to irritants or toxins at work
