How It Works

  • Coolant is delivered to the surface of the nasal cavity at room temperature
  • Coolant rapidly evaporates due to air/oxygen gas flow
  • Surface of nasal cavity cools due to evaporation
  • Brain and body is cooled through direct conduction pre-ROSC
  • Upon return of circulation, the brain and body are cooled through indirect convection as the cooled circulating blood removes heat hematogenously
