The device works by creating a local subatmospheric pressure environment,
Grahn says. "We stick the hand in a rigid chamber with an airtight seal
around the wrist, and then we draw a bit of the air out of the chamber," he
explains. "This causes blood to be pulled into the hand. Then we cool the
overlying skin surface of the palm of the hand [by circulating cool water
through a closed system on which the palm of the hand rests], which cools
the blood in the hand's vascular heat-exchange structures. Arteries deliver
blood directly from the heart to these vascular structures, and veins then
carry the blood from these structures back to the heart."
