Subject: CRYONICS.SCI CryoSpan Cooling Rate Info


Note: Although this message was sent completely separate from another
with subject Cryonics Talk, the 2 messages somehow got garbled with the
end of this appearing at the end of the other. Here is the second message
as it should have appeared.

     Since its formation CryoSpan has performed the cooldown of 2
neuro patients from dry ice (-79xC) to liquid nitrogen temperature
(-196xC). The rate of cooling chosen for these patients was based on
the best knowledge and experience available to CryoSpan from its
directors, officers and consultants, including cooling methods and
rates which had been published in Cryonics and elsewhere.
     ACS patient Jerry White was cooled down about a year ago over a
period of 12 days. At no time did Jerry's rate of cooling exceed 1
degree Celsius per hour.
     ACS patient Margaret Bradshaw was cooled down just recently
between January 17, 1995 and February 15, 1995. At no time did
Margaret's rate of cooling exceed 0.6 degree Celsius per hour.
     Both of these patients now reside in CryoSpan's stable, securely
locked, and continuously computer-monitored neuro dewar. Within a
couple of months, as soon as they are ready, all of CryoSpan's
patients will be transferred its new earthquake, fire, flood and
bullet proof, below ground vaults.
