Treatment of Heat Stroke
Victims of heat stroke must receive immediate treatment to avoid permanent organ damage. First and foremost, cool the victim.
Get the victim to a shady area, remove clothing, apply cool or tepid water to the skin (for example you may spray the victim with cool water from a garden hose), fan the victim to promote sweating and evaporation, and place ice packs under armpits and groins.
Monitor body temperature with a thermometer and continue cooling efforts until the body temperature drops to 101-102°F (38.3-38.8°C).
Always notify emergency services (911) immediately. If their arrival is delayed, they can give you further instructions for treatment of the victim.
