ABSTRACTBackground: Airway clearance techniques (ACTs) are recommended for people with bronchiectasis both in stable state and during an acute exacerbation. Research has previously investigated ACTs for individuals in a stable state, but the safety and efficacy of ACTs during an acute exacerbation has not been reviewed.Methods: A systematic review was completed for studies of ACTs undertaken in adults and children experiencing an acute exacerbation of bronchiectasis.
