First aid measures after heat stroke mainly include getting out of the hot environment, cooling treatment, and immediate medical treatment for severe cases.
After heat stroke, you can move the patient to a cool place or air-conditioned room and use cool water to spray or wipe the whole body.
If the patient is awake he/she can drink some cool salty drinks. If the patient is unconscious, place him/her in bed or on the floor, lying on his/her side or tilting his/her head to one side, to prevent asphyxiation or aspiration from vomit. Meanwhile, test his/her respiration and heartbeat. If the respiration and heartbeat stop, perform CPR immediately.
While performing the above operations, call the 120 emergency number and send the patient to the hospital for treatment.
