Airway clearance techniques help move and remove mucus from the lungs. They can be particularly useful for people with bronchiectasis, persistent sputum, mucus plugging or difficulty clearing secretions, including some people with ABPA, CPA and Aspergillus bronchitis.

Airway clearance does not treat the fungal infection or allergic response itself. It is a supportive part of respiratory care that can make mucus easier to clear, improve airway hygiene and help some people manage symptoms such as cough and chest congestion.

This hub brings together physiotherapy guidance and practical information about techniques including the Active Cycle of Breathing Technique (ACBT), huffing, positioning, nebulised saline and airway clearance devices such as PEP and oscillating PEP devices. The most appropriate technique varies between individuals, and a respiratory physiotherapist can help develop a suitable routine.
