From The Stargate Omnipedia
physician. Carmichael was on call when Teal'c
found himself unable to exit the Foxtrot Alpha Six simulation
utilising a modified virtual reality unit
developed by Dr. Bill Lee
and his team. He was forced to give the Jaffa
adrenaline and emergency stimulants to prevent his heart from stopping. Because of the electronics plugged into the man, a crash cart could not be used.
Carmichael was successful in keeping Teal'c alive just long enough so that he could complete the simulation.
