How Does Cryonics Work?

The best to explain how cryonics works is with the story of a 14 years old-girl that died due to cancer. When a person has been declared legally dead, the cryonic preservation company is informed and it dispatches a response team to attempt to keep the person's blood pumping around their body. The body is packed in ice and injected with various chemicals in an attempt to reduce blood clotting and damage to the brain.

Once the body reaches the cryonics facility it is cooled to just above water's freezing point and the blood is removed and replaced with organ preservation solution. The body's blood vessels are injected with a cryoprotectant solution to try to stop ice crystal formation in the organs and tissues and the corpse is cooled to -130C. The final step is to place the body into a container which is lowered into a tank of liquid nitrogen, kept at -196C. The schoolgirl died on October 17. She arrived at the Cryonics Institute near Detroit, Michigan, eight days later, becoming the 143rd patient
