摘要：
Devices for cerebral and systemic cooling via a patient's nasopharyngeal cavity are described. Cooling assemblies include at least one elongate tubular member having first and second lumens, a source of liquid coolant, a gas source communicating with the first lumen, and a switch for alternately connecting the liquid coolant source to the second lumen. The first lumen transports a compressed gas and the second lumen transports a volatile liquid. The pressurized fluid may be a perflurocarbon. The perfluorocarbon may be perfluorohexane, perfluoropentane, or 2-methyl-perfluoropentane. The gas may be air, oxygen, or a combination.
