Abstract:

Airway mucus is an important part of the human respiratory system's defense barrier. Under pathological conditions, excessive mucus secretion will block the airway, cause ventilatory dysfunction, and reduce mucociliary clearance and local defense functions. The common airway mucus hypersecretion disease in children is very different from that in adults. The assessment of airway mucus hypersecretion is still under exploration, and the core of its treatment is to reduce mucus production and promote mucus excretion.

Key words: airway mucus hypersecretion, mechanism, assessment, child
