During the process of cryopreservation, a cryonaut is placed in an ice bath while their blood is oxygenated and circulated throughout the body. While in the ice bath, the body is also perfused with cooling solutions and prepared for transportation to the cryonics service organization’s facility. There the cryonaut will be perfused with antifreeze cryoprotectant solution before being submerged in liquid nitrogen. The cryonaut’s temperature is lowered to a point at which all biological activity is halted and they are essentially frozen in time. They remain there indefinitely until the necessary achievements in science and the necessary advancements in technology are finally developed in order to revive them. For them, death is only the beginning.
I featured you on BlenderNation, have a great weekend!
