Subject: RE: DCS incident
HI Sergio,


If you want sound, factual, research based answers and/or recommendations to
this and any other question regarding DCS, you might try asking Dr. Michael
Powell.

Dr. Powell is the head of the Environmental Physiology and Biophysics lab at
NASA, specializing in decompression problems associated with Extravehicular
Activity.  NASA spends more money on decompression research than all other
organizations in the world, including the US Navy.  In fact, Dr. Powell's
research provides the basis for most of the US Navy's physiological studies and
research.  

In 1969, Dr. Powell started working for the Ocean System Division of Union
Carbide studying problems concerning decompression sickness. In 1975, Dr.
Powell went to Seattle, Washington, to work with Merrill Spencer, MD, at the
Institute of Applied Physiology and Medicine. In 1977 he took a leave to work
in Germany for three years at the Institute for Aerospace Medicine in Bonn. He
returned and remained at I.A.P.M. until 1989, during which time he directed the
human-subject tests of the DSAT/PADI Recreational Dive Planner. He joined NASA
at the Johnson Space Center in Houston in 1989.

You can see that Dr. Powell has an extensive background in the effects of
decompression on the human body.  He is the foremost leading authority in this
field and I would trust his opinion and advice above any other in matters of
DCS.

If you would like to have Dr. Powell publicly answering your questions, he
regularly spends time at 

http://www.scubaboard.com

You will most commonly find him posting in the Dr. Deco section of the forum.

Cordially,

Marie
