Claim 18:
19. A humidifier that provides humidification to breathing gas for ventilating a patient, comprising:
a sensor that monitors humidity information of the breathing gas flowing into the humidifier;
a controller that receives an inspiratory flow of the breathing gas flowing into the humidifier;
a processor that calculates, based on the inspiratory flow and the humidity information, an amount of water to add to the breathing gas to reach a desired humidity;
a valve commanded by the controller to cause delivery of the amount of water in bursts of water directly into a flow path of the breathing gas; and
a heating element commanded by the controller to heat a thermally-conductive material, wherein the bursts of water are vaporized upon contact of the water with the thermally-conductive material to form humidified breathing gas for delivery to a patient being ventilated by the ventilator.
