Clearance of mucus by the beating action of cilia is the primary means of removing inhaled particulates and airway debris from airways in healthy people. However many pulmonary diseases are associated with impaired mucociliary clearance mechanisms. For these patients, cough is the default airway clearance mechanism. Unfortunately most pulmonary disease patients can only produce low expiratory flow rates and have difficulty coughing for this reason.
