Abstract
A ventilation gas cooling apparatus is configured in a modular form adapted for selective removable engagement to a ventilator. The apparatus includes a gas inlet port, a gas delivery port, a pressure sensing port, and a thermoelectric cooler. The inlet port is fluidly connectible to a source of therapeutic breathing gas at an external end and is fluidly connectible to an inlet of the ventilator at an internal end. The delivery port is fluidly connectible to a patient circuit at an external end and is fluidly connectable to an outlet of the ventilator at an internal end. The pressure sensing port is fluidly connectible to both a pressure sensing port of the ventilator and to the patient circuit. The apparatus may further include a cooling fluid system operative to circulate either a gas or liquid coolant along at least a portion of a multi-lumen tube integrated into the patient circuit.
