Abstract: A method for cerebral and systemic cooling by providing a nebulized liquid having a boiling point of 38-300° C. The nebulized liquid is delivered as a mist or a spray via the nasal and/or oral cavities of a patient. The mist causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis. Compositions and medical devices for cerebral and systemic cooling are also provided. Cooling assemblies, and methods of use, are also provided that include flexible balloon assemblies that are inserted to various locations in a patient's body. The flexible balloons are then infused with a liquid having a temperature between about ?20° C. and about 37° C. The flexible balloon assemblies can be inserted into the nasal cavity, oral cavity, throat, stomach, and other locations to effect cerebral cooling.

Abstract: A method for transpulmonary cooling by providing a liquid having a boiling point of 38-300° C., more preferably 38-250° C., more preferably 38-200° C., more preferably 38-150° C., more preferably 38-80° C. The liquid is nebulized to form a mist. The mist is optionally cooled below room temperature and delivered to the airway of a patient so that the patient inhales the mist. The mist causes systemic cooling by evaporative heat loss when inhaled at room temperature and additionally by direct heat transfer when inhaled below room temperature. Compositions and medical devices for transpulmonary cooling are also provided.
