How to Chill a Brain







1. HOOK IT UP A paramedic slides the RhinoChill tubes up the nostrils and into the nasal cavity.
2. SPRAY A gas propellant drives perfluorocarbon coolant through the tube, which turns it into a fine mist.
3. COLD RUSH The mist settles on nasal-cavity and upper-throat membranes and evaporates instantly, cooling the blood running to the brain to lower its temperature to 93.2ºF in 90 minutes
