Cryogenic suspension, commonly known as cryonics, involves preserving a human body at cryogenic temperatures after legal death, with the aim of future revival. The Cryonics Institute, a member-owned organization, offers such services, emphasizing the potential of future medical technologies to restore life. They view cryonics as an "ambulance to the future," providing a chance for individuals to benefit from advancements that may not be available in their current time. This perspective is rooted in the belief that conditions deemed beyond rescue today could be treatable and reversible by future medical science. cryonics.org
The process of cryogenic suspension is intricate and requires meticulous planning. The Cryonics Institute outlines a comprehensive protocol that includes immediate stabilization after legal death, cooling the body to cryogenic temperatures, and perfusing the body with cryoprotectants to prevent ice formation. They stress the importance of pre-planning, as last-minute arrangements can compromise the quality of the suspension. This preparation involves legal agreements, funding, and coordination with professionals to ensure the best possible outcome. cryonics.org
