1. A method for humidifying ventilator-delivered breathing gas, comprising:
receiving, at a humidifier, inspiratory flow information about breathing gas flowing from a ventilator into the humidifier;
measuring, by the humidifier, humidity information for the breathing gas;
calculating, based on the inspiratory flow information and the humidity information, an amount of water to add to the breathing gas to reach a desired humidity;
delivering, by humidifier, the calculated amount of water in bursts of water directly into a flow path of the breathing gas;
vaporizing the bursts of water upon contact of the water with a heating surface in the flow path to form humidified breathing gas; and
delivering the humidified breathing gas to a ventilation tubing system for delivery to a patient.
