Central nervous system dysfunction is virtually universal at temperatures higher than 113° F. It first becomes apparent as confusion, Lethargy, or agitation and may progress to seizure and coma. There are two basic kinds of heat stroke. Classic heat stroke, in which people lose the ability to sweat, generally affects inactive people who are in hot environments. Exertional heat stroke, in which victims retain the ability to sweat, usually occurs during periods of physical exertion and muscle stress. Heat stroke commonly occurs during times of high temperatures combined with high humidity and low wind velocity. Some signs and symptom of heat stroke include the following: Temperature of 105° F or higher • Hot, reddish skin; skin can be wet or dry, since approximately half of all heat stroke victims sweat profusely Initially constricted pupils, later becoming dilated Tremors • Mental confusion and anxiety • initially deep, rapid breathing that sounds like snoring; breathing becomes shallow and weak as damage progresses Headache Dry mouth • Shortness of breath • Loss of appetite, nausea, or vomiting • Increasing dizziness and weakness • Convulsions, sudden collapse, and possible unconsciousness Seizures Left untreated, a patient may likely die. Emergency care of heat stroke is aimed at immediately cooling the body. Emergency care includes the following: • Remove the patient, when possible, from the source of heat. • Call an ambulance. • Remove as much of the patient's clothing as possible or reasonable, pour coal water over his/her body (avoiding the nose and mouth), fan the patient briskly, and shade from the sun if he/she is still outdoors. Wrapping a wet sheet around the patient's body and then directing an electric fan at the patient are also good ways of cooling. Cool the patient more slowly if he/she starts to shiver since that produces heat. • Elevate the patient's head and shoulders slightly during cooling, and make sure that he/she is comfortable. • Never give the patient stimulants or hot drinks.
