Lumpy sputum may be caused by infectious factors that lead to an increase in airway secretions as well as epithelial shedding, coupled with the fact that the patient’s airway will be in a drier condition in the presence of ischemia, which makes the sputum become sticky and even crusted, i.e., called sputum crusts into lumps. This situation is relatively dangerous because the sputum crusts will block the airway, and even blocking the airway will cause asphyxiation. In this case, the airway can be humidified, such as hydration, drinking water, intravenous rehydration, or through the means of nebulization to humidify the airway, to dilute the role of sputum. In addition, there is mechanical expectoration, or the use of a tracheoscope to reach inside the airway and suck it out.
