A cryonics company has frozen its first client in Australia in the hope of bringing him back to life in the future.

About Cryonics:

  • Cryonics, the practice of freezing an individual who has died, with the object of reviving the individual sometime in the future.
  • The word cryonics is derived from the Greek krýos, meaning “icy cold.”
  • It is an effort to save lives by using temperatures so cold that a person beyond help by today’s medicine can be preserved for decades or centuries until a future medical technology can restore that person to full health.
  • A person that is held in such a state is called acryopreserved patient”, because Cryonicists (the advocates of cryonics) do not regard the cryopreserved person as really dead.
  • Cryonic preservation can be performed only after an individual has been declared legally dead.
  • The process is initiated shortly after death, with the body being packed in ice and shipped to a cryonics facility.
  • There, the blood is drained from the body and replaced with antifreeze and organ-preserving compounds known as cryoprotective agents.
  • In this vitrified state, the body is placed in a chamber filled with liquid nitrogen, where it will theoretically stay preserved at -196 °C until scientists are able to find a way to resuscitate the body in the future.
  • Currently, there are a few hundred bodies that have been frozen through cryonics. 

Q1: What is Liquid Nitrogen?

Liquid Nitrogen is an inert, colorless, odorless, noncorrosive, nonflammable, and extremely cold element. It is a cryogenic liquid (Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid nitrogen has a boiling point of –320°F (–196°C).
