Research Summary Heat stroke is defined by Knochel and Ouchama (2002‚ p. 1978) as “a core body temperature that rises above 40°C (105°F) and that is accompanied by hot‚ dry skin and central nervous system abnormalities such as delirium‚ convulsions‚ or coma.” Heat stroke can be the result of either exposure to a high environmental temperature or from an elevated core temperature due to strenuous exercise. However‚ due to the presentation of an ‘unconscious unknown’ the diagnosis of heat stroke can be
