Abstract
An aerosolization device comprises a housing having a mouthpiece, an aerosol generator, a flow sensor and a controller. The controller is configured to begin operation of the aerosol generator upon receipt of a signal from the flow sensor indicating that a threshold flow rate has been achieved by a user when inhaling a tidal breath through the mouthpiece, and to stop operation after the passage of an operation time period that is selected such that continuation of the tidal breath delivers substantially all of the aerosol to the lungs.
