The question of how long someone's heart would have to be stopped for before you can safely say that regardless of what you do, you're not going to be able to revive them is avery tricky question. It's not as simple as saying after 10 or even 20 minutes there's no hope. For instance, there are countless people who have been subject to hypothermia, have their heart stopped for over 45 minutes, and still have been successfully revived. So many, in fact, that the current guideline set by the American Heart Association (AHA) is that you continue trying to revive the person until their core body temperature is above 95 degrees Fahrenheit- 95 degrees, because below that is the technical definition of hypothermia. The mantra in that situation is, "They're not dead until they're warm and dead."
