Mucus secretion in the lungs is a natural process that protects the airways from inhaled
insoluble particle accumulation by capture and removal via the mucociliary escalator …

Background Autogenic drainage is an airway clearance technique that was developed by
Jean Chevaillier in 1967. The technique is characterised by breathing control using …

BACKGROUND: Positive expiratory pressure (PEP) therapy imposes expiratory flow
resistance to increase airway diameter and enhance mucus clearance. PEP is achieved …

Background Oscillatory positive expiratory pressure (OPEP) devices are intended to
facilitate sputum clearance and reduce cough, but there is limited evidence for their …

Oscillating positive expiratory pressure (OPEP) devices have been shown to improve clinical …

Objectives Clearing secretions from the airway can be difficult for people with chronic
obstructive pulmonary disease (COPD). Mucus clearance devices (MCDs) are an option in …

Intrapulmonary percussive ventilation (IPV) has been postulated to enhance mucociliary
clearance by improving tracheobronchial sputum rheological properties. The IPV effects on …

Background: Patients undergoing Coronary Artery Bypass Graft (CABG) surgery often
develop pulmonary complications in the early post-operative period as result of decreased …
