An aerosol delivery system that includes an aerosol generator that aerosolizes a fluid for delivery to a patient. The aerosol generator includes a housing with a fluid chamber that fluidly communicates with a housing inlet and a housing outlet. Within the housing, the aerosol generator includes a support plate with an aperture that fluidly communicates with the housing outlet. A vibratable member couples to the support plate across the aperture. A piezoelectric actuator also couples to the support plate, and in operation expands and contracts to vibrate the vibratable member, which aerosolizes a fluid. The aerosol generator receives fluid through a fluid conduit that couples to the housing.
