Abstract
A respiratory therapy apparatus includes a rocker mechanism () that provides an oscillating resistance to expiration. The apparatus also includes an air entrainment arrangement () at its air inlet () having a ring orifice () connected via a gas inlet () to a source () of oxygen at elevated pressure. The oxygen emerging around the ring orifice () entrains ambient air and supplies this as a continuous flow of respiratory gas to the patient interface () to provide a positive airway pressure.
