Abstract: A humidifier, for a ventilation system, that includes an atomizer configured to deliver water droplets into a flow of breathing gases and a heating element configured to vaporize the water droplets emitted from the atomizer. The humidifier may be configured to set a target inhalation gas temperature based on internal temperature of a patient. Further, based on inspiratory flow and humidity data about breathing gases upstream of the atomizer of the humidifier, the humidifier may calculate and deliver an amount of water in one or more bursts of atomized water. Based on the target inhalation gas temperature, the humidifier may control a temperature of the heating element.

Abstract: Various embodiments of a tracheal tube having a shaped divider disposed therein for separation of a tracheal tube into multiple ventilation lumens are provided. In some embodiments, the divider divides a tracheal ventilation lumen from a bronchial ventilation lumen. In some embodiments, the shaped divider provides an irregular inner diameter that allows a relatively bulky device to be inserted into one or both lumens.
