Causes of phlegm in lungs

Sputum sounds in the lungs often indicate that there is sputum in the patient's airway, which often indicates that the patient's expectoration ability is relatively poor. Sputum sounds in the lungs can be seen in lung infection, chronic obstructive pulmonary disease, bronchiectasis and other related diseases. Moreover, the patient's constitution is normally relatively poor, and the patient's ability to expectorate autonomously may also be relatively poor. For this situation, on the one hand, it is necessary to deal with the cause and give anti-infection treatment. On the other hand, some sputum excretion measures need to be taken, such as oral administration of some expectorant drugs to promote sputum excretion of the patient, and auxiliary measures such as tapping the back to help the patient expectorate. Sometimes, it is even necessary to do bronchoscopy to clear sputum in the airway to help the patient expectorate.
