114. Pulm PEEPs Pearls: Airway Clearance Techniques in Non-CF Bronchiectasis

This week’s Pulm PEEPs Pearls episode is a focused discussion between Furf and Monty about non-pharmacologic techniques for airway clearance in the non-Cystic Fibrosis bronchiectasis population. This is a focused, high-yield discussion of the key points about airway clearance, including practical tips and a discussion of the evidence.

This episode was prepared in conjunction with George Doumat MD. Goerge is an internal medicine resident at UT Southwestern and joined us for a Pulm PEEPs – BMJ Thorax journal club episode. He is now acting as a Pulm PEEPs Editor for the Pulm PEEPs Pearls series.

Key Learning Points

1) Why airway clearance matters in non-CF bronchiectasis

Non-CF bronchiectasis is defined by irreversible bronchial dilation with impaired mucociliary clearance, leading to mucus retention.

Retained sputum drives the classic vicious cycle: mucus → infection → neutrophilic inflammation → airway damage → worse clearance.

Airway clearance techniques (ACTs) are meant to interrupt this cycle, primarily by improving mucus mobilization and symptom control.

2) What ACTs are trying to achieve clinically

Main benefits are:

More effective sputum clearance

Reduced cough/dyspnea burden

Improved activity tolerance and quality of life
