There are several staging systems for emphysema.

Emphysema and chronic bronchitis are classified as chronic obstructive pulmonary disease. It is a progressive disease that affects the terminal part of the lungs called alveoli. Disease features of shortness of breath and increased susceptibility to infections. In end-stage emphysema patients requiring bed rest and administration of oxygen and multiple medications. There are several staging systems for emphysema. They can divide people into several groups and predict the outcome furosemide in accordance with certain characteristics of the disease. Before the patients undergo pulmonary function. This test is important in further activity in the lungs. The results of pulmonary function determining prognosis in most patients suffering from emphysema. In emphysema, the destruction of the alveoli walls leads to the accumulation of air in the lungs and the patient has difficulty with exhalation. This staging system was established Global Initiative for chronic obstructive pulmonary disease, hence the title of Production Systems. The most important factor in the gold production is the amount of air exhaled in first second force pulmonary function. This quantity of air, known as forced expiratory volume, or FEV1. According to GOLD staging system has four stages of emphysema. The first phase includes a light form of the disease, in which FEV1 or 80% of normal value or above this level. In the second stage, which is also known as a moderate stage of disease, FEV1 ranged from 50% to 80% of normal value. The third stage or severe form of emphysema hell with FEV1 of 30% to 50% of normal value. Finally, the fourth stage emphysema functions with less than 30% of normal FEV1. The last step is actually a very severe form of disease. The higher stage disease, the worse the prognosis for patients. This is another statement of emphysema. In this case, the factor used in production is not associated with FEV1. Namely, Bode emphysema staging system based on the impact of the disease in many areas of life. In Bode staged by means of body mass index, due to weight and height of an individual. O means the obstacle. Respiratory obstruction can be mild or severe, where patients require additional supplies of oxygen. Obstruction of readily measured pulmonary function. D means dyspnoea which is short of breath. Finally, E means the exercise tolerance. Exercise capacity refers to the distance that can be overcome within six minutes. Unfortunately, no matter how the production system can be useful, they just can not predict the actual results in each patient. Forecast as individual and unique. .
