Abstract
Methods for cerebral cooling are described. Cooling assemblies include elongate tubular members, a reservoir containing a pressurized fluid, and a manifold connecting the reservoir and elongate tubular members. After insertion of the elongate tubular members into the patient's nostrils, a pressurized fluid is delivered onto a surface of the patient's nasal cavity through a plurality of ports in the elongate tubular members. The delivery of the fluid causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis.
