The mucociliary escalator is one of the major defense mechanisms, which protect the lung, and if the mucociliary escalator fails, it increases the risk that the normal and potentially pathogenic, inhabitants of the nose, throat and the back of the mouth, will descend into the lung, resulting in a potentially life-threatening pneumonia ( Anatomy and Physiology, 2013, p. 139).
