Doctors describe the severity and progression of emphysema staging system. Although all of emphysema is unique, emphysema staging can help with the weather. However, no system setting emphysema can accurately predict what will happen to any individual with emphysema. Emphysema formulation requires lung function (PFTS). Doctors use PFTS follow lung capacity in people suffering emphysema. In Association, a person with emphysema breathes and blows air through the tube while the air flow is measured. Emphysema weather man largely determined by the PFTS. Damage to the lungs in emphysema creates a small pocket of air into the lungs where air is trapped. Trapped air makes it difficult for people with emphysema to blow strongly. The more air trapped, the worse becomes a function of the lungs. Over time it becomes harder to breathe emphysema and pulmonary function test results fall.
One of the main production system is called emphysema GOLD. It was established an expert group called the Global Initiative for chronic obstructive lung disease. The main factor in the Golden staging emphysema is the amount of air a person can breathe with emphysema force in one second. This is called forced expiratory volume, or FEV1. Stage I, mild emphysema: FEV1 greater than or equal to 80% of normal. Stage II, moderate emphysema: FEV1 less than 80% but greater than or equal to 50% of normal. Stage III, severe emphysema: FEV1 less than 50% but greater than or equal to 30% of normal. Phase IV, very severe emphysema: FEV 1 less than 30% of normal, or less than 50% of normal low levels.
Setting Gold emphysema is well known and widely used. The above statement Golden emphysema emphysema provides worse prognosis. However, GOLD staging emphysema does not include other areas of activity are important, such as people living with emphysema feel. Emphysema affects more than able to take air through the tube. Index Bode, another system emphysema setting, the effect of emphysema a few areas in life:
* Body Mass Index (B), or weight adjusted for height. * Airflow limitation (O for obstruction), measured pulmonary function. * Shortness of breath (D for dyspnea), measured profiles. * Capacity (E), measured by how far a person with emphysema can walk in six minutes. Bode index does slightly better at defining emphysema prognosis, emphysema than production of gold standards. Emphysema prediction is impossible to determine in any individual. Although emphysema setting can help determine the severity of emphysema, it can not predict the future. There was no large studies to determine the effect of emphysema on life expectancy. The largest and best study included only a few hundred people. Emphysema setting is useful, but emphysema varies between two people on the same stage. In other words, the limited available statistics emphysema are not reliable for individuals who seek their life emphysema. However, the above statement emphysema person, the less their long-term emphysema life. Gold and Bode emphysema staging system provide some other information, summarized as follows:
* More lasix 6 mg than 80% of people with mild emphysema alive four years later. * 60% to 70% of people with mild emphysema alive four years later. * Among people with severe emphysema (FEV1 35% of normal), 50% are alive after four years. * People with worse symptoms of emphysema (eg, inability to walk around the house and severe weight loss) have the lowest life expectancy of emphysema. Remember that life emphysema varies widely, even among people with the same pulmonary function and Bode index evaluation. Even with the most severe emphysema, the chances of survival one year higher than 90%. Your doctor or pulmonologist can provide more information.
