Chronic obstructive pulmonary disease (COPD) refers to chronic obstructive pulmonary disease (COPD), for which there is no clinical remedy and which cannot be cured. COPD causes chronic cough, sputum, wheezing, chest tightness, and dyspnea, which affects the quality of life and health. Since COPD is usually not self-healing and cannot be cured, there is no prescription for eradicating COPD, but active treatment can slow down the progression of the disease. During acute exacerbation, patients with hypoxemia can receive oxygen through nasal cannula or face mask. Patients may also be treated with nebulized inhalation of bronchodilators such as salbutamol and ipratropium bromide, glucocorticosteroids such as methylprednisolone, and expectorants such as aminoglutethimide hydrochloride and N-acetylcysteine, as directed by a physician. If the patient is in the stabilization period, long-term home oxygen therapy, appropriate rehabilitation training, and vaccination are feasible. For those whose disease is induced by occupational or environmental dust, irritating gases, etc., they should be removed from the polluted environment. It is recommended that patients with COPD cooperate with doctors to actively treat the disease, pay attention to adjusting the mentality, and avoid choosing folk remedies that have no scientific basis.
