Claim:
1. An aerosol transition adapter for delivering an aerosolized active agent to a patient receiving ventilation support, the aerosol transition adapter comprising: a housing having a proximal end and a distal end, the proximal end having an aerosol passage for receiving an aerosol produced by a source of aerosol comprising an aerosolized active agent and the distal end having an exit port, the housing having a length between the distal end and the proximal end; a carrier gas connection port configured to receive a carrier gas from a positive pressure gas source, which is in communication with a plurality of carrier gas exit ports, and wherein the plurality of carrier gas exit ports are arranged adjacent to the aerosol passage in a pattern that at least partially encircles a flow of aerosol from the aerosol passage; a carrier gas conduit connected to the carrier gas connection port, wherein the carrier gas conduit is in communication with the positive pressure gas source; and an inner cavity, which is adapted to receive the aerosol from the aerosol passage and the carrier gas from the plurality of carrier gas exit ports and to direct streams of carrier gas to at least partially encircle and flow in parallel with a main direction of a flow of the aerosol along the length of the housing toward the exit port, the inner cavity having a proximal portion having a conical inner wall, which extends outward to an inner wall of a distal portion of the inner cavity, and wherein the plurality of carrier gas exit ports are located on the conical inner wall.
