Following this pronouncement, the rules pertaining to procedures that can be performed change radically because the individual is no longer a living patient but a corpse. In the initial cryopreservation protocol, the subject is intubated and mechanically ventilated, and a highly efficient mechanical cardiopulmonary resuscitation device reestablishes circulation.
Cryonics, which began in the Sixties, is the freezing – usually in liquid nitrogen – of human beings who have been legally declared dead. The aim of this process is to keep such individuals in a state of refrigerated limbo so that it may become possible in the future to resuscitate them, cure them of the condition that killed them, and then restore them to functioning life in an era when medical science has triumphed over the activities of the Grim Reaper.
