Cystic Fibrosis: Airway Clearance Techniques – Cochrane Reviews
- For individuals wiht cystic fibrosis (CF), a genetic condition impacting respiratory and digestive systems, airway clearance techniques are crucial.
- The review considered conventional chest physiotherapy, breathing techniques like active cycle of breathing and autogenic drainage, positive pressure devices such as positive expiratory pressure (PEP) therapy, oscillating devices,...
- The analysis included six Cochrane Reviews, one comparing any chest physiotherapy type against no physiotherapy or coughing alone.

Airway Clearance Techniques: What Works for Cystic Fibrosis?
Updated June 4, 2025
For individuals wiht cystic fibrosis (CF), a genetic condition impacting respiratory and digestive systems, airway clearance techniques are crucial. These methods help clear thick mucus from the lungs, reducing infections and lung function decline. A recent Cochrane review examined various airway clearance techniques and their effectiveness.
The review considered conventional chest physiotherapy, breathing techniques like active cycle of breathing and autogenic drainage, positive pressure devices such as positive expiratory pressure (PEP) therapy, oscillating devices, and exercise. These techniques vary in cost and the need for assistance or equipment.
The analysis included six Cochrane Reviews, one comparing any chest physiotherapy type against no physiotherapy or coughing alone. The other five reviews compared different airway clearance techniques, with some overlap.
the review found moderate evidence suggesting PEP therapy and vibrating oscillating devices have similar effects on lung function, specifically forced expiratory volume in one second (FEV1), after six months.The evidence was insufficient to draw firm conclusions on other comparisons or outcomes like individual preference and quality of life.
Reports of harms like acid reflux, collapsed lungs, coughing up blood, or decreased oxygen were infrequent in the original trials. The review also noted a lack of evidence to determine if any specific airway clearance therapy carries more risk than others.
The Cochrane review highlighted that while all reviews were well-conducted, the original trials often lacked detailed information, making quality assessment challenging. Missing information on outcome measures further complicated the analysis.
The researchers graded the evidence for lung function when comparing PEP to oscillating devices as moderate. However, evidence comparing different airway clearance techniques for other outcomes was graded as low or very low quality.
What’s next
The review underscores the need for more long-term, high-quality randomized trials comparing different airway clearance techniques in people with cystic fibrosis to establish definitive conclusions about their effectiveness and impact on quality of life.
