Older people with more phlegm that cannot be coughed out are mainly clinically common due to inflammatory reactions in the respiratory system, such as acute bronchitis and acute attacks of chronic bronchitis, and can be treated in a way to promote coughing up phlegm. For example, you can gently pat the back of the elderly from bottom to top to vibrate the tissues of the lungs can achieve the purpose of expectoration, and you can also gargle and rinse the throat with light salt water to clear the phlegm in the mouth. If necessary, budesonide nebulizer and chymotrypsin nebulizer inhalation can be chosen to dilute the phlegm to promote the discharge of phlegm. You can also take cough and phlegm-relieving drugs, such as carboxymethystane oral solution, tranylcypromine syrup, and cough granules to clear lungs and reduce phlegm. For inflammatory reactions combined with bacterial infections, antibiotic treatment, such as penicillin, amoxicillin, clindamycin, etc., is used when necessary.
