Pulmonary insufficiency refers to the dysfunction of ventilation and air exchange of the lungs, which may be due to bronchial asthma, chronic obstructive pulmonary disease and other diseases. It can be treated with bronchodilators, glucocorticosteroids and ventilation, which should be decided according to the cause of the disease. 1. Bronchial asthma: in the acute stage, short-acting β2 agonists such as salbutamol and terbutaline can be applied, glucocorticosteroids such as methylprednisolone, theophyllines such as aminophylline, and short-acting anticholinergic drug ipratropium bromide can be applied, and mechanical ventilation can be given in case of unsatisfactory results. In chronic remission, inhaled glucocorticosteroids such as budesonide, long-acting β2 agonists such as salmeterol and formoterol, long-acting anticholinergic drugs such as ipratropium bromide, leukotriene modulators such as montelukast sodium, and small-dose theophyllines can be applied. 2. Chronic Obstructive Pulmonary Disease (COPD): bronchodilators such as salbutamol and ipratropium bromide can be used, and in severe cases, glucocorticoids such as budesonide can be used in combination with hypoxic ventilation. Pulmonary insufficiency can also be caused by other diseases, such as tuberculosis, lung tumors, etc., should be timely medical care, specific drugs should be used under the guidance of the doctor.
