Electroacoustical airway secretion-clearing system
Definition
An assembly of devices designed to provide externally applied vibrations to the chest wall of a patient via an electroacoustical transducer (the applicator) to loosen excessive airway secretions [mucus or sputum (phlegm)] to promote airway clearance and improve bronchial drainage for patients with respiratory disease [e.g., cystic fibrosis (CF), neuromuscular disease, bronchitis, bronchiectasis, chronic obstructive pulmonary disease (COPD)]. It consists of a mains electricity (AC-powered) frequency generator, a hand-held applicator containing the transducer, and connecting cable. It is intended to be operated by a healthcare professional in a professional setting.
