Since there are many secretions in the respiratory tract that cannot be expelled, there are some options to assist in the expulsion of phlegm. By patting the patient’s back from the bottom to the top by a family member or friend, the phlegm in the airway is made to vibrate and promote the expulsion. You can drink more warm boiled water and juice to dilute the phlegm in the airway and promote its expulsion. You can also choose the steam method by pouring hot boiling water into a cup and inhaling the airway with the hot water vapor from the mouth and nose to make the phlegm in the airway become diluted and expelled from the body. In addition, we should go to the environment where the air is fresher, do deep inhalation appropriately, and cough out the phlegm in the airway vigorously after holding the breath, which can promote the movement of airway cilia and facilitate the discharge of phlegm. In addition is to take expectorant and phlegm-relieving drugs, for example, you can choose carboxymethylstilbestrol oral solution, aminoglutethimide syrup, brown combination, etc.
