Asthma causing dyspnea in the elderly indicates an acute exacerbation. First, appropriate antispasmodic and wheezing drugs should be given immediately to relieve clinical symptoms, such as albuterol sulfate aerosol can be chosen to relieve dyspnea caused by bronchoconstriction and spasm, and also to clarify the specific trigger. If the symptoms are severe, such as persistent chest tightness, shortness of breath and dyspnea, glucocorticoids such as methylprednisolone and budesonide should be added for treatment. If there is a combination of hypoxia or respiratory failure, it is necessary to give oxygen or use ventilator to assist ventilation.
