A cold water immersion system
using a portable suit has been shown
to cool human-sized swine to 91.4° F
(33° C) within 45 minutes.11 A continuous flow of water is cycled over
the patient and through a pump,
drawing heat off the body in a much
more rapid process than gel pads or
cooling blankets. As the patient reaches the target temperature, the water is drained off the patient and the suit
discarded. The patient will remain
cool for another 12 to 24 hours.
