COPD General - Chronic Obstructive Pulmonary Disease

What Is COPD?

COPD stands for chronic obstructive pulmonary disease. There are 2 major diseases included in COPD: 1) chronic bronchitis, and 2) emphysema. In both, narrowed bronchi make it hard to exhale. In chronic bronchitis, enlargement of the mucous glands and too much mucus production contribute to the narrowing. In emphysema, narrowing comes from damage to the bronchi themselves and is more severe. Inflammation triggered by inhaled irritants also contributes to COPD.

What Causes COPD?

Smoking accounts for about 85% of COPD cases. Heavy smokers are at highest risk. Secondhand smoke and other inhaled toxins account for COPD in some nonsmokers. In others, an inherited protein deficiency is to blame. But in some cases, the cause is unknown.

Symptoms

COPD starts gradually and progresses slowly. At first, there are no symptoms. Little by little, problems appear, usually in middle-aged people.

A morning "smoker´s cough" is often the first complaint. The cough gradually gets worse and occurs throughout the day.
Next, shortness of breath develops-at first, only during exercise. As the disease gets worse, breathing becomes a chore even at rest.
Wheezing is another common symptom.
Most patients also become tired and weak.

Chronic bronchitis.
Patients with chronic bronchitis have a recurrent cough that brings up large amounts of thick, discolored phlegm almost every day for 3 months or longer over at least 2 years. Over time, the lung disease can put a strain on the heart, and some patients develop congestive heart failure.

Emphysema.
Patients with emphysema look and sound different. Their cough is scant and dry. But their shortness of breath is more severe, and they breathe faster than normal. They stay pink and don´t accumulate fluid, but they lose weight, their muscles tend to waste away, and they develop large, barrel-shaped chests.

Most patients with COPD have mixed features of chronic bronchitis and emphysema. Many patients also have 2 to 3 flare-ups each year. These are abrupt flare-ups that are often triggered by lung infections. Symptoms get much worse, and aggressive treatment may be needed.

Diagnosis

Your doctor will ask about your smoking history and exposures to secondhand smoke, fumes, and dust. Be sure to report any family history of COPD, particularly if your symptoms began in young adulthood and you haven´t been exposed to tobacco. You´ll also be asked about symptoms of cough, phlegm, shortness of breath, wheezing, fatigue, and weight changes.

Physical exam.
Your doctor will check your lips, skin, and nails for bluish discoloration that suggests low oxygen levels. Your nails may be abnormally rounded; you may have fluid in your legs and feet.

Your chest exam is the most important part of the exam. With chronic bronchitis, your doctor may hear wheezing and abnormal gurgling sounds. With emphysema, your chest may be enlarged and sound hollow when your doctor taps on it.

Tests and x-rays.
The most important test is a lung function test, the forced expiratory volume at one second (FEV1). It measures the amount of air you can breathe out with a maximal effort in 1 second.

FEV1 values depend on a person´s age, sex, and height. Doctors can diagnose COPD and estimate how bad it is based on how a patient´s FEV1 compares to normal. By repeating lung function tests, doctors can tell if COPD is getting worse and tailor therapy to the stage of the disease.

If you have emphysema, your chest x-ray will show enlarged lungs. Scarring and large, air-filled cavities may also be evident. CT scans can show damage at an earlier stage, but no imaging test can gauge the severity of COPD or predict its outcome.

In many cases, your doctor will order additional tests, such as complete blood counts, an EKG to look for heart strain, an analysis of your sputum, and a test to measure the oxygen in your blood.

Treatment: Lifestyle

Avoid tobacco and secondhand smoke.f

Good nutrition is also important.
Make sure you eat plenty of fruits, vegetables, and fish (to learn more, see the Brochure, "Good Eating for Good Health"*). Drink a lot of fluids too to keep phlegm loose and easy to cough out.

Exercise.
A gradual program of low- to moderate-intensity exercise helps muscles get the most bang out of the oxygen that damaged lungs can deliver. Structured pulmonary rehabilitation programs also offer breathing exercises designed to strengthen chest muscles.

Preventing infection is essential.
Be sure your flu and pneumonia immunizations are up to date. Keep your distance from folks with respiratory infections. Wash your hands carefully, using an alcohol-based hand rub.

Treatment: Medications

Early treatment is important.
Talk to your doctor about which treatments are best for you. While drugs will not cure your COPD, they can help you breathe better.

Quick relievers/rescue inhalers.
Also known as short-acting beta agonists, quick-relief drugs relieve symptoms quickly by relaxing the muscles that surround bronchial tubes, enabling the tubes to open wider. Carry your quick-relief medication with you at all times. Ask your doctor about when and how often to use a quick reliever.

Maintenance medications.
These drugs, including beta-agonists, corticosteroids, and anticholinergics, are taken every day, usually by inhalation, to help make breathing easier over the long-term. Because these drugs act on different aspects of the disease, your doctor may recommend you use different types of therapy in combination.

Since most COPD medicines are inhaled, your doctor may prescribe a handheld device or inhaler. Be sure to ask for instructions on how to use your inhaler. Doctors also may prescribe anti-inflammatory drugs and antibiotics, as needed, to treat flare ups and respiratory infections. Contact your doctor immediately if your breathing becomes worse, if you develop a fever, or if your phlegm becomes thicker, discolored, or more abundant.

Treatment: Oxygen

COPD patients with low blood oxygen levels can benefit from long-term, round the clock oxygen therapy. For home use, oxygen can be stored in cylinders or generated by machines called oxygen concentrators. Portable tanks can provide several hours of oxygen away from home. Safe oxygen therapy requires physician supervision and responsible cooperation by patients and household members.

Treatment: Surgery

Some patients with severe emphysema may benefit from special types of lung operations.

Expert evaluation by experienced physicians is mandatory. A few COPD patients may be eligible for lung transplantation.

Even when COPD causes lung damage, early diagnosis, treatment, and lifestyle changes can slow the process, ward off complications, and improve your quality of life.
