Phlegm in the tracheaBreathing with soundCoughing up white phlegm can be treated with medication and mechanical expectoration to expel phlegm. 1. When there is phlegm in the trachea, it can be considered that the mucous membrane of the respiratory tract due to pneumonia or bronchitis produces more phlegm, which adheres to the trachea and lungs. When the breath has ventilation flow, there may be sound vibration. 2. Pharmacological treatment: expectorant drugs such as Ambroxol and Bromhexine can be used to dilute sputum, and nebulized inhalation such as acetylcysteine can be used to reduce sputum. If necessary, glucocorticosteroids such as dexamethasone can be used to eliminate airway inflammatory reaction and reduce sputum production. 3. Physical sputum expectoration: strengthen turning and back patting to expel sputum, as well as bedside suction tube to suction sputum, if necessary, tracheoscopic suction treatment. It should be noted that when there are more sputum sounds, one should consult a specialist in time and under the guidance of a doctor.
