Abstract: A system and a method for generating a respirable aerosol from a liquid solution or liquid suspension. A liquid solution or liquid suspension is supplied at a liquid pressure, and a pressurized aerosolizing gas is supplied at a pressurized aerosolizing gas pressure to an aerosol generating nozzle having an aerosol exit orifice through which the liquid solution or liquid suspension is released into an aerosolizing space. Controlling the pressure of an aerosolizing gas by a controller modulates a gas pressure of the pressurized aerosolizing gas in the aerosolizing space to alternatingly exceed above and drop below a fluid pressure at the fluid exit, controlling an aerosol generation duration by the time the pressurized aerosolizing gas pressure is kept by the controller below the fluid pressure at the fluid exit.
