WHAT IS CRYONICS?
Deep freezing of the body to -196 ° C (-321 ° F).
The antifreeze compounds are injected into the corpse to prevent the cells from being damaged.
The hope is that medical science advances enough to bring the patient back to life.
Two major US organizations UU They carry out cryonics in the United States: Alcor, in Arizona, and the Cryonics Institute, in Michigan.
The Russian firm KrioRus is one of the two facilities outside the US. UU It offers the service, together with the European laboratory of Alcor in Portugal.
HOW DO YOU WANT TO WORK?
The process can only take place once the body has been declared legally dead.
Ideally, it begins within two minutes after the heart is interrupted and no more than 15 minutes.
The body must be packed in ice and injected with chemicals to reduce blood clotting.
In the cryonics facility, it is cooled to just over 0 ° C and the blood is replaced with a solution to preserve the organs.
Cryopreservation is the deep freezing of a body at -196 ° C (-321 ° F). Antifreeze compounds are injected into the body to prevent damage to the cells
The body is injected with another solution to stop the formation of ice crystals in organs and tissues, then cooled to -130 ° C.
The last step is to place the body in a container that is lowered to a tank of liquid nitrogen at -196 ° C.
WHAT IS THE SUCCESS OPPORTUNITY?
Many experts say there are none.
Organs such as the heart and kidneys have never been frozen and thawed successfully.
It is even less likely that a whole body, and the brain, can be without irreversible damage.
The charges at the Cryonics Institute start around £ 28,000 ($ 35,000) to & # 39; members & # 39; for the cryopreservation of the whole body.
The rival group Alcor charges £ 161,000 ($ 200,000) while the KrioRus procedure will return £ 29,200 ($ 37,600).
HOW LONG DOES IT BEFORE PEOPLE CAN RETURN TO LIFE?
The Cryonics organizations claim that it could be decades or even centuries.
However, medical experts say that once the cells are damaged during freezing and become "porridge" they can not become living tissue again, just as you can not turn a scrambled egg into a raw egg.
