High-frequency assisted airway clearance systems combine positive expiratory pressure or oscillatory positive airway pressure with integrated nebulizers to improve the delivery of aerosols and assist with airway clearance. This aerosol study evaluated lung delivery efficiency during positive expiratory pressure and oscillatory positive airway pressure therapy of 2 high-frequency assisted airway clearance/nebulizer systems.
