Patients with bronchitis can be treated with nebulization. Bronchitis refers to an acute inflammation occurring in the bronchial mucosa and its surrounding tissues, which can cause a variety of clinical symptoms, such as fever, cough, sputum, and even chest tightness, shortness of breath, and difficulty in breathing. Nebulization is only a way of administering medication, and the specific purpose depends on the medication used. Therefore, if a patient with bronchitis presents with significant pus and yellow sputum that cannot be easily coughed up, acetylcysteine can be nebulized for expectorant treatment. If chest tightness, shortness of breath and dyspnea occur, nebulized salbutamol sulfate can be used for bronchodilatation treatment. In addition, some patients who are inconvenient to take medication and have bacterial infection can be treated with nebulized tobramycin and other antibiotics.
