Clearance of secretions is a common problem in patients who experience acute respiratory tract infections. Although the offending agent is a major factor, the degree of severity of ineffective airway clearance depends on many other factors: pulmonary host defenses, presence of underlying pulmonary disease, age, lifestyle habits, environments, airway clearance self-management skills, and time of specific treatment.
