Emphysema means “inflate or swell”, which makes sense because in the lungs of people with emphysema, the alveolar air sacs, which are the thin walled air spaces at the ends of the airways where oxygen and carbon dioxide are exchanged, become damaged or destroyed. The alveoli permanently enla...
We examined the effects of starvation on lung structure in rats allowed only one fifth of their measured daily food consumption until they lost 40% of their initial body weight, and evaluated volume-pressure relationships in saline-filled lungs, lung morphometric and connective tissue morphologic feat...
In most people, emphysema will be diagnosed by X-ray or lung-function tests.A regular chest X-ray may show typical changes of emphysema. These include:enlargement of the lungs scarring formation of holes (bullae).However, these changes may not appear until significant damage has occurred. ...
Emphysema andchronic bronchitisare the two main types of chronic obstructive pulmonary disease (COPD). These conditions are called "chronic" because they are ongoing (for life) and "obstructive" because it’s as though something is blocking the smooth flow of air in and out of the lungs. "Pu...
A comparison of the percentage of predicted elastic recoil revealed that both emphysema groups were significantly different from normal lungs. In addition, the total lung capacities were significantly different between the three groups. In the group with an emphysema score greater than 5 we found a ...
People with alpha-1 antitrypsin deficiency have aninheritedautosomal condition that results in an increased breakdown of elastin in the lungs, resulting in COPD (emphysema). When foreign irritants and substances enter the alveoli, usually byinhalation, an inflammatory process is initiated. Chemical mess...
Emphysema is caused by the destruction of air sacs in the lungs, mainly from exposure to cigarette smoke. Symptoms include shortness of breath, even when resting, coughing with mucus, wheezing, and tightness in the chest. Chronic bronchitis is an inflammation in the lining of the bronchial tube...

While the chest x-ray demonstrateslung hyperlucency, a flattened diaphragm, increased AP diameter, and increased retrosternal air in hyperinflated emphysematous lungs, subtle emphysema changes can be missed. In contrast, CT scanning plays an important role in the diagnosis of emphysema. Using high-...
