An aerosol delivery system for aerosolizing a fluid for delivery to a patient, comprising: a controller; a pump, and an aerosol generator, comprising: a housing defining a fluid chamber having a housing inlet and a housing outlet, wherein the housing defines a vent aperture fluidly coupled to the fluid chamber, and the vent aperture is configured to vent at least one of gas, liquid, and foam from the housing, and the outlet is adapted to couple to an endotracheal tube, or a nasal cannula, or a nasal mask, or a tracheostomy tube, or a mouthpiece, a support plate operably coupled to the housing, wherein the support plate defines an aperture; a vibratable member operably coupled to the support plate so as to be positioned across the aperture; a piezoelectric actuator coupled to the support plate, wherein the piezoelectric actuator expands and contracts to vibrate the vibratable member which aerosolizes a fluid; and a fluid conduit (22, 122) having a distal end spaced apart from the vibratable member so as to be configured to deliver the fluid to the vibratable member, wherein the distal end of the fluid conduit is positioned about 1.0 mm to about 0.001 mm from the vibratable member to facilitate adhesion of substantially all of the delivered fluid to the vibratable member using surface tension forces regardless of an orientation of the housing until the fluid is aerosolized by vibration of the vibratable member; wherein the pump is for pumping fluid from a fluid source through the fluid delivery conduit to the vibratable member, and the controller includes one or more processors that execute instructions stored on one or more memories to drive operation of the pump and the aerosol generator. a controller; a pump, and an aerosol generator, comprising: a housing defining a fluid chamber having a housing inlet and a housing outlet, wherein the housing defines a vent aperture fluidly coupled to the fluid chamber, and the vent aperture is configured to vent at least one of gas, liquid, and foam from the housing, and the outlet is adapted to couple to an endotracheal tube, or a nasal cannula, or a nasal mask, or a tracheostomy tube, or a mouthpiece, a support plate operably coupled to the housing, wherein the support plate defines an aperture; a vibratable member operably coupled to the support plate so as to be positioned across the aperture; a piezoelectric actuator coupled to the support plate, wherein the piezoelectric actuator expands and contracts to vibrate the vibratable member which aerosolizes a fluid; and a fluid conduit (22, 122) having a distal end spaced apart from the vibratable member so as to be configured to deliver the fluid to the vibratable member, wherein the distal end of the fluid conduit is positioned about 1.0 mm to about 0.001 mm from the vibratable member to facilitate adhesion of substantially all of the delivered fluid to the vibratable member using surface tension forces regardless of an orientation of the housing until the fluid is aerosolized by vibration of the vibratable member; wherein the pump is for pumping fluid from a fluid source through the fluid delivery conduit to the vibratable member, and the controller includes one or more processors that execute instructions stored on one or more memories to drive operation of the pump and the aerosol generator. a housing defining a fluid chamber having a housing inlet and a housing outlet, wherein the housing defines a vent aperture fluidly coupled to the fluid chamber, and the vent aperture is configured to vent at least one of gas, liquid, and foam from the housing, and the outlet is adapted to couple to an endotracheal tube, or a nasal cannula, or a nasal mask, or a tracheostomy tube, or a mouthpiece, a support plate operably coupled to the housing, wherein the support plate defines an aperture; a vibratable member operably coupled to the support plate so as to be positioned across the aperture; a piezoelectric actuator coupled to the support plate, wherein the piezoelectric actuator expands and contracts to vibrate the vibratable member which aerosolizes a fluid; and a fluid conduit (22, 122) having a distal end spaced apart from the vibratable member so as to be configured to deliver the fluid to the vibratable member, wherein the distal end of the fluid conduit is positioned about 1.0 mm to about 0.001 mm from the vibratable member to facilitate adhesion of substantially all of the delivered fluid to the vibratable member using surface tension forces regardless of an orientation of the housing until the fluid is aerosolized by vibration of the vibratable member; wherein the pump is for pumping fluid from a fluid source through the fluid delivery conduit to the vibratable member, and the controller includes one or more processors that execute instructions stored on one or more memories to drive operation of the pump and the aerosol generator.
