1. “Cryonics – A Science Fiction than Serious Science" Presented by : SheetalNarkar

2. What is CRYONICS ?? “The deep-freezing of human bodies at death for preservation and possible revival in the future” “The preservation of legally dead humans or pets at very low temperature in the hope that future science can restore them to life”

3. CRYONICS Legal death : is a legal pronouncement by a qualified person that further medical care is not appropriate and that a patient should be considered dead under the law Clinical death : is the term for cessation of blood circulation and breathing James Bedford is the first person known to have been placed in cryonic suspension in 1967.

5. Scientists search for biological antifreezes on human organs to freeze and thaw them without destroying delicate cells

7. Cryonics process

8. CRYONICS PROCESS Legal Death – Cardiac Arrest (After cardiac arrest, the brain cells start dying after 6 minutes) Body is placed on Cardio – pulmonary support (Body cooled to 15 ºC) Simultaneously the body is packed in ice ice

10. Calcium Channel Blockers

11. Free Radical InhibitorsBlood is replaced by saline solution. This is called as Blood Wash Out (The body is cooled to -10 ºC)

12. CRYONICS PROCESS Saline is replaced by a glycerol based cryoprotectant. This is called as Perfusion Body is cooled in the Silicone Oil Bath/ Insulated Box with dry ice vapors, cooled with dry ice. ( - 100 ºC , 2 – 7 days )

13. CRYONICS PROCESS Body is then further cooled in Special Holding Tanks – gradually cooled with liquid nitrogen vapors to – 196 ºC (5-7 days) Finally the body is placed in Insulated Storage Tank – “Dewar” or Fiberglass “Cryostat”

14. Obstacles to success

16. This causes injuries that are not reversible with present technology.

17. Water freezes inside cells causing them to burst is a myth, but damage from freezing can still be serious.

18. Cryonics uses cryoprotectants to reduce this damage.

20. Often in cryonics the brain is without oxygen for long time and at warm temperatures causes ischemic injury

22. Revival requires repairing damage from :

23. Lack of oxygen

24. Cryoprotectant Toxicity

25. Thermal Stress (Fracturing)

26. Physical Therapy to regain function of the body (similar in coma)

27. Reversing effects that caused patient deathIn many cases, Tissue Regeneration will be necessary

28. Institutes of cryonics

30. World Leader in the branch of Cryonics

31. Founded in 1972

32. Future Patients signed up = 650

33. Patients cryopreserved = 59

35. Founded in 1976

36. Total Members = 833

37. Members with Contract = 398

38. Volunteers = 16

41. Pioneering Cryonics Service Provider

42. Conducted their first Cryonics Suspension in 1974

43. Cryopreserved Patients = 23

45. It is a support for residents of Australia, New Zealand and others countries in the region having suspension arrangement.

47. FINANCIAL ISSUES

50. Contrary to popular belief, cryonics is not just for the rich -- in fact, most people signed up for suspension could best be described as "middle class".
