No air can not get new air enters the lungs.

Emphysema long-term progressive lung disease, and it is a type of chronic obstructive pulmonary disease (COPD). The disease occurs in the deterioration of air sacs in the lungs. Alveolus or small air sacs in the lungs are separated by thin walls or membranes containing capillaries. Membranes between the alveoli allow exchange of gases. Molecules of oxygen providing red blood cells to be used in another part of the body, while a molecule of carbon dioxide to separate and enter the alveoli to be exhaled. Emphysema destroys the alveolar membrane and capillary blood, which prevents transmission of oxygen and carbon dioxide through the membrane. The main symptom of emphysema is shortness of breath because the body is not getting enough oxygen. First, a person has difficulty breathing through the destruction of the alveoli and blood vessels, impeding air flow. In advanced stages of emphysema is also associated with loss of elasticity in the walls of the alveoli. This leads to more breathing problems, as there is no exchange of gases due to the collapse of the alveoli and small airways. No air can not get new air enters the lungs. Emphysema may be due to genetic predisposition, aging, exposure to air pollution and lack of alpha-1-antitrypsin enzyme, but the most common cause is smoking. Emphysema is not curable disease, but can be controlled with treatment and subsequent destruction of the lung can be prevented. Quitting smoking is the main treatment for emphysema. Being a progressive disease, emphysema can be divided into four categories: light, medium, heavy and very heavy emphysema. Mild emphysema is mild cough and lung function close to normal. Moderate stage emphysema associated with pulmonary function less than 80% of normal. Severe emphysema is characterized by 50% or less normal lung capacity, and in very severe emphysema of the lungs buy lasix generic are working with less than 1/3 of the nominal capacity. If emphysema is diagnosed early and the victim quit prognosis is usually good, where the patient can have normal life expectancy. On the other hand, very severe emphysema is seen as the final stage of the disease and symptoms are life threatening. As the disease progresses, lung capacity gradually decreases lungs are susceptible to infection and risk of heart failure. In non-smoking, emphysema treatment includes drugs, oxygen and inhalers to slow the decline in lung function. In some cases, surgery is performed to remove part of the lung, which has lost its function. .
