1. A breath-actuated nebulizer comprising:

  • a housing having a horizontal section defining an upper airway and an air outlet for transporting an aerosol to a patient, and a vertical section defining a fluid reservoir;

    a pressurized gas inlet adjacent a fluid orifice, the pressurized gas inlet positioned to direct pressurized gas from the vertical section in a direction perpendicular to the horizontal section; and

    an actuating assembly horizontally movable relative to the pressurized gas inlet in response to breathing of the patient through the horizontal section, wherein the actuating assembly comprises;

    a shaft extending through the horizontal section, the shaft having a first end movably connected with the horizontal section; and

    first and second arms each having a proximal end connected to a second end of the shaft at a perpendicular angle to the shaft, and the first and second arms each having a distal end movable relative to the pressurized gas inlet, wherein the actuating assembly is movable to a nebulizing position in response to an inhalation of the patient and wherein the actuating assembly is movable to a non-nebulizing position in response to exhalation of the patient.
