Respiratory diseases are common and frequently occurring illnesses, with primary lesions in the trachea, bronchi, lungs, and chest cavity. Mild cases often present with coughing, chest pain, and impaired breathing, while severe cases can lead to difficulty breathing, hypoxia, and even respiratory failure, which can be fatal. In cities, it ranks as the third leading cause of death, while in rural areas, it ranks first. Of even greater concern is that due to air pollution, smoking, population aging, and other factors, the incidence and mortality rates of chronic obstructive pulmonary disease (COPD, including chronic bronchitis, emphysema, and cor pulmonale), bronchial asthma, lung cancer, diffuse interstitial lung fibrosis, as well as pulmonary infections, are increasing rather than decreasing both domestically and internationally.
