How long does slow lung block last?

Chronic obstructive pulmonary disease (COPD) is an important disease affecting human health. If COPD patients are diagnosed in time and treated regularly, normal has no effect on survival. If the symptoms of poorly controlled patients gradually worsen, pulmonary function declines year by year, showing serious complications, and complicated with cardiac insufficiency, patients may show malignant events. If regular medication is given under the guidance of doctors, COPD is the same as other diseases, and has no effect on survival. Poor control can affect patient quality of life.
