COPD the abbreviation used for the Chronic Obstructive Pulmonary Disease is generally a disease which greatly causes the lungs problems and almost it destructs them completely. This is one of the major causes of death in almost all the global nations and in USA; it is the fourth highest death cause disease. This is a deadly disease and almost over than 85,000 people every year died due to this. This can be cause due to other several reasons but, tobacco consumption is considered it major happening cause. Apart from this consumption of tobacco, high smoking rate can also cause this deadly disease in the humans. Generally, the COPD life expectancy is very less and also it causes large number of severe health problems in the people. But, on the other hand if it is early detected due to their early symptoms and also it get treated too early in their early stages then the life expectations can be greatly increased.

Life expectancy can also be increased if the consumption of tobacco reduced to the greater extent and also smoking reduced heavily because lungs having the unique capacity to recover. COPD life expectancy to increase also requires some additional health care measures that must have to take by the patients or its victims to reduce their harmful impacts. When the intensity of this deadly disease goes beyond the first initial stage then only reduction in the smoking cannot help the victims to increase the expectancy of their life. In such critical situations, patients are provided with the oxygen therapy and they must have to inhale the required amount of oxygen through the masks or some additional nasal cannulae, which somewhere placed inside their nostrils. Patients then have to buy some of the oxygen tanks for their home use also.

When this COPD moves far away from the second stage and when it reaches to the final stage then, this oxygen therapy also not works properly to increase the life expectancy. Then, in such difficult situations, lung transplantations seem to be the only single options for the patients to enhance their life expectancy. At this time, the average life expectancy of the patients will increase up to 2 to 3 years or even more.
