emphysema Emphysema is a chronic respiratory disease where there is over-inflation of the air sacs (alveoli) in the lungs, causing a decrease in lung function, and often, breathlessness.n the early stages of emphysema, the only result may be dysfunction of the small airways. Patients with emphysema may show an increase in the total amount of air that is in the lungs (total lung capacity), but a decrease in the amount of air that can be breathed out after taking a deep breath (vital capacity).

- Emphysema is difficulty breathing due to air trapped in the lung, resulting in reduced lung capacity. Smoking is usually the cause, as it damages the linings of the air sacs in the lungs making them close. This leads to areas of trapped air in your lungs. Other causes may include coal dust and other pollutants.

- In this article. Emphysema is a form of chronic (long-term) lung disease, usually caused by smoking. Because of lung damage, people with emphysema have difficulty blowing air out. The major symptom of emphysema is shortness of breath.In most people, symptoms of emphysema are slowly progressive.hortness of breath is by far the most common of emphysema symptoms. Most people with emphysema first notice something's wrong when they become winded during a previously routine activity. This might be climbing stairs or mowing the lawn.

emphysema A. It's a chronic lung disease, characterized by destruction of the walls of the air sacs (alveoli) where the blood exchange oxygen and CO2 with the air. The disease leads to obstruction of the airflow, air trapping inside the lungs, and to many long term complications, and eventually to death.n the early stages of emphysema, the only result may be dysfunction of the small airways. Patients with emphysema may show an increase in the total amount of air that is in the lungs (total lung capacity), but a decrease in the amount of air that can be breathed out after taking a deep breath (vital capacity).

Emphysema Emphysema, also called pulmonary emphysema, condition characterized by widespread destruction of the gas-exchanging tissues of the lungs, resulting in abnormally large air spaces. Lungs affected by emphysema show loss of alveolar walls and destruction of alveolar capillaries. As a result, the surface available for the exchange of oxygen and carbon dioxide between inhaled air and blood traversing the lungs is reduced.

What is the difference between: Emphysema, COPD, Asthma, and Chronic Bronchitis? Emphysema. Emphysema is a disease of the lung in which the alveoli are destroyed. The capillary vessels that aid in transporting blood and air through the lungs become destroyed with the alveolar walls.As the person takes a breath in, the vessels and alveoli become compressed.OPD. This is a condition that is also preventable. Chronic obstructive pulmonary disease, or COPD, is one of the most common diseases associated with the lungs. The two forms of the disease are emphysema and chronic bronchitis. One of the reasons many people develop COPD is from smoking.

Subcutaneous Emphysema What is Subcutaneous Emphysema? A rare compulsive build-up of effervesces of air or gases like carbon dioxide trapped within the hypodermic tissue is termed as subcutaneous emphysema. It is observed as bloating of the skin around the neck and covering of the chest wall.

What Are the Symptoms of Emphysema? View All. Symptoms of emphysema are insidious in nature and may not, at first, be easy to recognize. Emphysema is among a group of lung diseases known as COPD, in which the alveoli of the lungs become damaged, causing them to enlarge and burst. Because the alveoli are where oxygen and carbon dioxide are exchanged, damage to this area makes it difficult for people with emphysema to expel all their air. This causes a build-up of carbon dioxide in the body.

emphysema noun. Emphysema is defined as a medical condition where there is air in body tissues or where the air sacs in the lungs are damaged in a way that causes shortness of breath. A medical condition caused by years of smoking that damages the air sacs in your lungs and makes breathing hard is an example of emphysema.mphysema. noun. 1  A pathological condition of the lungs marked by an abnormal increase in the size of the air spaces, resulting in labored breathing and an increased susceptibility to infection. 2  It can be caused by irreversible expansion of the alveoli or by the destruction of alveolar walls.

emphysema Emphysema is the most common cause of death from respiratory disease in the United States, and is the fourth most common cause of death overall. There are 1.8 million Americans with the disease, which ranks fifteenth among chronic conditions that cause limitations of activity.

Emphysema Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung).

- Emphysema is a disease of the lungs that usually develops after many years of smoking. Both chronic bronchitis and emphysema belong to a group of lung diseases known as chronic obstructive pulmonary disease (COPD) .mphysema is a condition that involves damage to the walls of the air sacs (alveoli) of the lung. Alveoli are small, thin-walled, very fragile air sacs located in clusters at the end of the bronchial tubes deep inside the lungs. There are about 300 million alveoli in normal lungs.

- Emphysema results when the delicate linings of the air sacs in the lungs become damaged beyond repair. Most commonly, the toxins in cigarette smoke create the damage. The lung changes of emphysema evolve slowly over years: As the fragile tissues between air sacs are destroyed, air pockets in the lungs develop.

Emphysema The decrease in lung elasticity, the trapping of air in the lungs, and the loss of alveolar surface area means that the person must breathe harder to force carbon dioxide out of the lungs and draw in oxygen. A common outward sign of emphysema is a barrel-shaped chest caused by overinflation of the lungs.
