Abstract: The present disclosure relates to a transportable device for providing a cooled, oxygen-containing gas flow for supplying to a body of mammal via the respiratory tract, in particular a human being, in order to lower the body temperature. The device comprises a storage device comprising at least one fluid reservoir and at least one heat exchanger, wherein the storage device is designed to store an oxygen-containing fluid in the fluid reservoir and for providing a discharge flow of the oxygen-containing fluid. The heat exchanger is designed to cool the provided discharge flow by transferring heat to a cooling stream of a stored fluid and provided by the storage device, and a cooled, oxygen-containing gas flow for supplying to the body emerges from the heat exchanger.
