When patients with bronchitis have dyspnea, they need to be treated symptomatically according to the specific causes, as follows: a. Chronic bronchitis with dyspnea is mostly suggestive of acute exacerbation of chronic obstructive pulmonary disease, and such patients can be treated with bronchodilators, such as albuterol sulfate aerosol inhalation, theophylline extended-release tablets, doxorubicin, etc., to play a role in antispasmodic and asthma. Patients can also use long-acting bronchodilators, such as tiotropium bromide powder aerosol, to slow down the rate of lung function decline. Some patients with respiratory distress in chronic obstructive pulmonary disease need a short course of intravenous glucocorticoids to relieve their symptoms of respiratory distress. Second, for acute bronchitis with dyspnea, if the patient is caused by a violent cough, resulting in bronchospasm, at this time, while anti-infection, strengthen symptomatic treatment such as cough suppression and wheezing. Some patients can be induced to have dyspnea due to sticky sputum that is not easily coughed out, so expectorant drugs can be used, sometimes combined with nebulized inhalation, to relieve the symptoms of wheezing.
