Answer

This is a noninvasive technique for cooling moderate hyperthermia. It was reported in volunteers that it reduces core body temperature by approximately 0.3°C per minute; however, in heatstroke patients, it reduced core body temperature significantly more slowly: from 0.05°C to 0.09°C per minute. [12]

Remove all of the patient’s clothing.

Insert a rectal probe for continuous monitoring.

Mist over patient constantly, using spray bottles filled with tepid (15°C) water.

Place large fans to circulate warm room air (ideally 40°C) directed at the patient.
