It depends, oddly enough, on the temperature. At normal body temperature, the answer is about 3 minutes. However, a cold body, such as someone who has fallen through ice and drowned, can be revived after as much as 20 minutes. That's why we have a saying in the Emergency Room: "They're not dead until they're warm and dead".
