When a person has been revived after cardiac arrest but is still unconscious, cooling the body is the first thing done by emergency staff. Reducing the body temperature would improve the patient's chance for a full recovery. Blowing cold air over the body or using ice packs can take hours to work effectively.
Now, there is a product called a ThermoSuit that can reduce a person's body temperature in about 30 minutes. The product is a plastic suit that is filled with cold water. There are medical centers that are currently using it and say that the survival rate of their cardiac arrest patients has risen from 35 percent to 60 to 70 percent.
