=== Cooling ===

In cryonics, several forms of cooling have been used:

# '''Dry Ice:''' The patient is surrounded by dry ice until reaching a temperature of -78.5 ºC.
# '''Spraying of Liquid Nitrogen Vapor:''' The method used by CI consists of placing the patient inside a cooling box on a supine position. Liquid Nitrogen vapor is sprayed from an overhead tube and is distributed by a fan.
# '''Isopropyl Alcohol:''' The patient is immersed in a bath of alcohol.
# '''Immersion:''' The patient, either a [[#Whole Body|Whole Body]] or a [[#Neuro|Neuro]] is slowly immersed in Liquid Nitrogen, with the vapor providing interim cooling. In the case of neuropatients, the Neurocan was placed in a cryogenic dewar which was immersed in the Liquid Nitrogen.

(Note that in cooling the patient is already placed in a sleeping bag or another form in insulation.)
