Can a bronchoscope remove phlegm from the lungs?
Under normal circumstances, a bronchoscope can usually suction mucus from the lungs, but it can only remove secretions from the larger and medium-sized airways. The specific analysis is as follows:
A bronchoscope is a tube composed of optical fibers and equipped with an operating channel. Suctioning mucus via bronchoscopy typically involves using negative pressure through this channel to extract secretions. However, the bronchoscope can only reach relatively large bronchi and cannot access smaller bronchioles under 1 mm in diameter; therefore, mucus located in the fine or deeper bronchioles cannot be suctioned out. After bronchoscopic suctioning, mucus may continue to accumulate and should be expelled naturally through coughing.
Patients may also take expectorant medications under a physician's guidance to facilitate mucus clearance. Commonly used medications include carbocisteine oral solution, ambroxol hydrochloride oral solution, and ambroxol-terbutaline oral solution.
