| Chronic obstructive pulmonary disease (COPD) refers to a number of |
| chronic lung disorders. It is characterized by persistent, progressive |
|
airflow obstruction and dyspnea |
|
| The disease is degenerative......... causes irreversible lung damage....... |
|
and it has no cure. |
| |
|
COPD encompasses emphysema, alpha antritrypsin deficiency-related |
|
(AAT) emphysema, and chronic bronchitis. Nearly 16 million Americans |
|
suffer from COPD, which is the fourth leading cause of death, claiming |
|
the lives of 87,000 Americans annually. |
| |
|
Chronic bronchitis: A long-standing inflammation of the breathing |
|
tubes (airways) that are called bronchi. The airways in the lungs |
|
become narrow and partly clogged with mucus. |
| |
|
Emphysema: A chronic pulmonary disease in which the air spaces |
|
(alveoli) are enlarged and destroyed. The elasticity of the lung is |
|
lost and air gets "trapped" in the lung, which causes a decrease in |
|
respiratory function and breathlessness. |
|
|
COPD gets gradually worse over time. At first there may be only a |
|
mild shortness of breath and occasional coughing. Then a chronic |
|
cough develops with clear, colorless sputum. As the disease |
|
progresses, the amount of oxygen in the blood decreases and carbon |
|
dioxide increases. The cough becomes more frequent and more and |
|
more effort is needed to get air into and out of the lungs. |
|
|
The quality of life for a person suffering from emphysema diminishes |
|
as the disease progresses. Eventually, there is severe shortness of |
|
breath often leading to the total dependency on the administration of |
|
oxygen around the clock. |
|
|
In later stages of the disease, the heart may be affected. Death occurs |
|
when the function of the lungs and heart is no longer adequate to |
|
deliver oxygen to the body's organs and tissues. |
