Französische Leitlinien zur nasalen Inhalation mit 100 Hz Schall-Vibration mit dem Pureneb Aerosonic+
Auszug aus den französischen Leitlinien:
Some devices have additional functions to enhance upper air-way deposition. The sonic function adds a sound-wave to theaerosol to improve maxillary sinus penetration and deposition.Studies on the operating principles of these devices go back tothe 1950s: the principle is to induce acoustic hyperpressure inthe ostium, displacing the air and aerosol toward the maxillarysinuses. Several in-vitro studies on models of varying sophistica-tion demonstrated the benefit of introducing sound [12–14], butonly very recently has it been demonstrated in humans, in scinti-graphic studies [10,15,16]. Sinus deposition is 3–5-fold greater than with a nebulizer without sonic boost.The manosonic function is a derivative of this sonic function,adding hyperpressure to create positive pressure in the nasal cavi-ties; this is automatically applied in the nose at the exact momentof swallowing, so as to transfer the aerosol toward the Eustachiantube. Systems with this extra function are known as manosonicaerosol generators.
Nebulizers with additional sonic vibration are recom-mended in rhinosinus pathology. Ultrasonic aerosols aresuitable for bronchopulmonary pathology. Strong agreement.
Nasal plugs are to be preferred. Mouth end-pieces arereserved to laryngeal and bronchopulmonary applications.Strong agreement.
Oro-nasal masks cause deposition on the face and withinthe oral cavity and should be reserved to patients unable touse a nasal plug. Strong agreement.
