The portable and battery powered RhinoChill^® System achieves cooling by using compressed air/oxygen to spray a liquid coolant, perfluorocarbon, into the patient’s nostrils with a catheter.

The coolant vaporizes against the upper surface of the nasal cavity and absorbs heat from the tissue. As this tissue supplies the brain with blood, this results in a strong, adequate and rapid cooling effect on the brain. Clinical trials in Europe (PRINCE and PRINCESS studies) have demonstrated that RhinoChill^® was able to lower the patient’s temperature several hours sooner than alternative practices in use at intensive care units.
