1. A continuous high-frequency oscillation breathing treatment apparatus comprising:

  • a breathing head assembly defining a first cavity, a second cavity spaced from the first cavity, a pressure monitoring port, and an entrainment cavity, wherein said first cavity is operatively associated with said second cavity through a venturi tube, said first cavity is operatively associated with said pressure monitoring port through a feedback tube that extends generally parallel with the venturi tube, and said entrainment cavity is operatively associated with said second cavity;

    a nebulizer operatively associated with said entrainment cavity of said breathing head assembly;

    an injection nozzle operatively associated with said second cavity of said breathing head assembly;

    at least one first aperture operatively associated with said first cavity of said breathing head assembly;

    a plurality of second apertures operatively associated with said second cavity of said breathing head assembly;

    at least one gas input operatively associated with said nebulizer; and

    at least one gas input operatively associated with said injection nozzle.
