When breathing, the lungs grunt, mostly dry and wet rales in the lungs, according to the cause of the disease can be given to anti-infective treatment, anti-tuberculosis treatment, symptomatic treatment, treatment of the original disease, and so on. 1. Anti-infective treatment: chronic bronchitis and chronic obstructive pulmonary disease (COPD) are often characterized by dry rales; pneumonia is commonly characterized by limited or diffuse wet rales. Acute exacerbation of chronic bronchitis and chronic obstructive pulmonary disease is usually associated with infections, and bacterial infections are common, and bacterial pneumonia is the most common. It is necessary to use antibiotic anti-infective treatment along with the treatment of underlying diseases, such as the use of cephalosporin antibiotics or levofloxacin, etc., or the use of sensitive antibiotics according to the bacterial culture of the sputum and the drug susceptibility test; in the case of infections of influenza A and B viruses and other infections, it can be used to treat with oseltamivir. If the infection is caused by influenza A and B viruses, oseltamivir can be used; if the infection is caused by fungus, voriconazole, fluconazole and other antifungal treatment can be used. 2. Anti-tuberculosis treatment: bronchial tuberculosis can be detected as limited dry rales; pulmonary tuberculosis can be detected as limited wet rales; after completing other laboratory tests related to tuberculosis to make it clear, this kind of patients should adopt standardized anti-tuberculosis treatment, such as oral drugs like isoniazid, rifampicin, ethambutol and so on. 3. Symptomatic treatment: patients with fever can use non-steroidal anti-inflammatory drugs such as acetaminophen to relieve fever; those with phlegm and cough can be treated with cough suppressant and expectorant therapy, etc. The medicines that can be used include strong loquat lozenges, licorice tablets, and aminoglutethimide dispersible tablets. 4. Treatment of primary disease: chronic obstructive pulmonary disease can be controlled by bronchodilator drugs (e.g. salbutamol, ipratropium bromide, etc.); cardiac failure resulting in pulmonary stasis, bronchopneumonia, etc., should be strengthened (e.g. use of cardiac drugs digoxin), diuretic treatment (use of diuresis, etc.), etc.; if caused by tumors, should be based on the type of pathology and staging of the choice of surgery, radiotherapy and so on. The choice of the above treatment modalities should be made under the guidance of specialized physicians.
