Abstract

An aerosolization system comprises a gas flow passage, and an aerosol generator (16) comprising a plate (20) having a plurality of apertures and a vibratable element disposed to vibrate the plate (20). The aerosol generator (16) is adapted to aerosolize a liquid for delivery into the gas flow passage. A flow sensor (32) is configured to sense a gas flow through the passage, and a controller (28) is employed to actuate the aerosol generator based on the gas flow sensed by the flow sensor (32).
