Spirometry Tests for COPD - Topic Overview
Spirometry is the best test to assess lung function. It often is used to evaluate a person who has a chronic cough and sputum ( mucus ) production and a history of risk factors for chronic obstructive pulmonary disease (COPD),even if shortness of breath is not present. It is also used to determine whether a specific therapy has improved lung function or whether your lung disease is getting ...
COPD: Clearing Your Lungs
COPD (chronic obstructive pulmonary disease) is a long-term illness that makes it hard to breathe, but learning to clear your lungs may help you save energy and oxygen, and help prevent lung infections.
Bullectomy for COPD - Topic Overview
Chronic obstructive pulmonary disease (COPD) weakens the structure of the lung and may also damage the tiny air sacs (alveoli) in the lung. When these air sacs break down,larger airspaces known as bullae are formed. Bullae sometimes can become so large that they interfere with breathing and may cause complications: They can burst,leading to a collapsed lung ( pneumothorax ). A collapsed lung ...
COPD's Effect on the Lungs - Topic Overview
Chronic obstructive pulmonary disease (COPD) slowly damages the lungs and affects how you breathe. COPD's effect on breathing In COPD,the airways of the lungs (bronchial tubes) become inflamed and narrowed. They tend to collapse when you breathe out and can become clogged with mucus. This reduces airflow through the bronchial tubes,a condition called airway obstruction,making it difficult ...

Lung Function in COPD - Topic Overview
Lung function means how well your lungs work. When you have COPD,your lungs can't move as much air in and out as they should. And the more serious your COPD is,the less air your lungs are able to move. Spirometry tests are used to measure lung function. They measure how much air you breathe out when you take long,deep breaths and push the air out of your lungs. For people with COPD,the ...
COPD and Alpha-1 Antitrypsin (AAT) Deficiency - Topic Overview
Alpha-1 antitrypsin (AAT) is a protein normally found in the lungs and the bloodstream. It helps protect the lungs from the damage caused by inflammation that can lead to emphysema and chronic obstructive pulmonary disease (COPD). People whose bodies do not produce enough of this protein (AAT deficiency) are more likely to develop emphysema and to do so at a younger-than-normal age (30 to 40 ...
Lung Infections and COPD - Topic Overview
When you have COPD,it’s easier for you to get lung infections like bronchitis and pneumonia. If you are still smoking,the risk may be even higher. COPD causes your airways to get narrower. That makes it harder for your lungs to clear out mucus. And that mucus makes an inviting home for the germs that cause lung infections. These infections also cause more shortness of breath and coughing ...
