1. A method for humidifying ventilator delivered breathing gases, comprising:
receiving, at a humidifier, inspiratory flow information about breathing gases upstream of an atomizer of the humidifier;
measuring, by the humidifier, humidity information for the breathing gases upstream of the atomizer;
calculating, based on the inspiratory flow information and the humidity information, an amount of liquid to add to the breathing gases to reach a desired humidity;
delivering, via the atomizer, the amount of liquid in bursts of atomized liquid directly into a flow path of the breathing gases to form humidified breathing gases; and
delivering the humidified breathing gases to a ventilation tubing system for delivery to a patient being ventilated.
