Systems and methods for lowering the core body temperature of subject are generally described. In certain embodiments, the core body temperature of a subject can be lowered by using a heat exchanger configured to cool an intubation gas that is transported to the subject via an intubation tube. The intubation tube used to deliver cooled intubation gas to the subject can include one or more features facilitating cooling of the subject. For example, in certain embodiments, the intubation tube may include multiple lumens. In some embodiments, one of the lumens can be used to deliver the relatively cool intubation gas and a second lumen can be used to transport relatively warm gas away from the patient's lungs. In certain embodiments, the system can be configured such that water (e.g., in the form of ice particles and/or liquid mist) can be delivered to the subject via the intubation tube, which can provide an enhanced cooling effect. |
