ABSTRACT:
A continuous high-frequency oscillation breathing device delivers therapy during both inhalation and exhalation in order to assist in clearings secretions the lungs. A fixed shrouded-venturi patient interface circuit is combined with medicated aerosol to deliver continuous high-frequency oscillation therapy. Fixed open apertures in the patient interface circuit allow ingress and egress of flow, and are calibrated to allow exhalation and prevent stacking of successive breaths.
