New methods could halt the dying process

The exact point at which a person is dead and beyond resuscitation is becoming increasingly blurred.
As scientists learn more about the point at which the body dies, the less it seems we actually know about the process. Previously it had been accepted that irreversible brain damage can occur only a few minutes after someone's heart stops, but now it seems that it may be possible to revive someone even up to an hour after being declared clinically dead.

"Historically, when a person's heart stopped and they stopped breathing, for all intents and purposes, they were dead," said Dr. Sam Parnia. "There was nothing you could do to change that." With cases on the rise of people being successfully revived after longer and longer periods it seems that the traditional concept of the point of death may in fact be obselete.

One of the key techniques being considered in the resuscitation of patients is to induce hypothermia, a state in which the core temperature of the body is reduced by several degrees and which can help protect the brain for much longer, increasing the chances of a successful revival.

"What we've come to learn is that those notions of irreversibility of brain damage are dead wrong," said neurologist Dr. Stephan Mayer. "If you make those judgments too soon without going fully all the way, you may be actually writing people off."

The use of hypothermia in cardiac incidents is integral to currently used resuscitation algorithms. The method does make a statistical difference in recovery. It will interesting to see results when this fully transfers to the field for widespread EMS application.

A little more investing in Stem cell research to stop aging, and we can call it a ball game.

An ice cream truck relabeled "Ambulance" epic, but seemingly acceptable near death experience equiped with fudgecicles

epic, but seemingly acceptable near death experience equiped with fudgecicles Yeah, and I'm not totally certain about this, but I heard that some NFL medic teams have special ice packs to put around a perceived severe neck injury for a similar purpose... slowing down the injury progression prior to getting in a hospital. Don't know if it's in widespread use.

Wow think thats a great feat for medical science. But can they cure the person from the disease that caused him/her to die?

Wow think thats a great feat for medical science. But can they cure the person from the disease that caused him/her to die? i think this method most likely apllies to impact or coma based injuries id imagine
