Respiratory disease is a common disease. The main lesions are in the trachea, bronchi, lungs and chest. It is the third most common chronic disease in my country after cardiovascular and diabetes. Due to factors such as air pollution, smoking, and an aging population, morbidity and mortality (the third leading cause of death among residents) remain high all year round. Chronic respiratory diseases are mainly represented by COPD and asthma, and also include pneumoconiosis, lung cancer and tuberculosis. The main manifestations of mild disease are cough, chest pain, and respiratory obstruction. The clinical manifestations of severe disease are dyspnea and hypoxia. In severe cases, death due to respiratory failure.

Chronic Obstructive Pulmonary Disease (COPD) is a common respiratory disease characterized by airflow limitation. It has high prevalence, high disability and mortality rates, long disease course and treatment period, and hospitalization rate during acute exacerbation. Higher characteristics. The three main symptoms of COPD are dyspnea, chronic cough, and sputum production. About 62% of patients with moderate to severe COPD have symptoms (such as dyspnea, cough, sputum production, wheezing, or chest tightness) that change from day to week or from week to week. , In addition, serious comorbidities, such as lung cancer, bronchiectasis, cardiovascular disease, osteoporosis, etc., will have an important impact on disease mortality. Smoking, occupational dust, chemicals and air pollution are the main risk factors for COPD in China.
