Chronic obstructive pulmonary disease (COPD) may be a serious respiratory illness, including bronchitis, asthma, emphysema, pulmonary heart condition, etc. Therefore, these diseases have varying degrees of airway obstruction and poor breathing, in order that they are collectively mentioned as chronic obstructive pulmonary disease, or COPD for brief.

If the condition of COPD isn't well controlled, the body will show endless and irreversible progressive development. Usually from bronchitis and asthma to emphysema, then to pulmonary heart condition. hypertrophy is usually attacked by acute infections, which induces the guts functional failure, lung failure, if the rescue isn't timely at this point, it's often easy to steer to death.

Patients with COPD, on the one hand, thanks to the contraction of the trachea and bronchi, the secretion within the lumen increases, which results in airway obstruction and poor breathing; on the opposite hand, thanks to the huge destruction of the bronchi and alveoli, the ventilation function is obstructed; the above two aspects directly cause the patients’ body being during a state of hypoxia for an extended time.

Oxygen inhalation can prevent the further development of the disease and prolong life. Medical research shows that the anticipation of COPD patients who enforce home oxygen therapy a day is significantly longer than that of COPD patients who haven't received home oxygen therapy.

Oxygen inhalation can improve the immunity of the entire body and therefore the local tract, reduce the occurrence of acute respiratory infections; avoid acute lung function and coronary failure. Statistics of medical data show that after COPD patients enforce home oxygen therapy, the amount of emergency medical visits or the typical number of hospitalization days thanks to respiratory complications has been significantly reduced, their condition is additionally mild, and medications are reduced, which may avoid long-term hospitalization. There are many problems like the value burden.

Oxygen inhalation can improve the standard of lifetime of patients. for instance, patients with shortness of breath after activities and unable to require care of themselves can go downstairs on their own after a period of home oxygen therapy. The shortness of breath is relieved, the mental condition improves, the activity ability is enhanced, and therefore the quality of life is significantly improved.
