First aid - Heatstroke



















































































































































































































































































































































Heatstroke is the most severe of the heat-related problems, often

resulting from exercise or heavy work in hot environments combined with

inadequate fluid intake.



Young children, older adults, people who are obese and people born with

an impaired ability to sweat are at high risk of heatstroke. Other risk

factors include dehydration, alcohol use, cardiovascular disease and

certain medications.



What makes heatstroke severe and potentially life-threatening is that

the body's normal mechanisms for dealing with heat stress, such as

sweating and temperature control, are lost. The main sign of heatstroke

is a markedly elevated body temperature — generally greater than 104 F

(40 C) — with changes in mental status ranging from personality changes

to confusion and coma. Skin may be hot and dry — although if heatstroke

is caused by exertion, the skin may be moist.



Other signs and symptoms may include:



Rapid heartbeatRapid and shallow breathingElevated or lowered blood pressure Cessation of sweatingIrritability, confusion or unconsciousnessFeeling dizzy or lightheadedHeadacheNauseaFainting, which may be the first sign in older adults



If you suspect heatstroke:



Move the person out of the sun and into a shady or air-conditioned space.Dial 911 or call for emergency medical assistance.Cool

the person by covering him or her with damp sheets or by spraying with

cool water. Direct air onto the person with a fan or newspaper.Have the person drink cool water, if he or she is able.
