No injured cavers recorded.
On August 28, 1982, a group of six experienced cavers entered Sullivan's Cave in Indiana. They penetrated to nearly the rise of the Sullivan River when one of the group displayed signs of advanced hypothermia. Three of them went for help when the victim refused to proceed. The State Police were called and they called NCRC, who alerted Bloomington and Central Indiana Grotto members. The Bloomington cavers answered the call accompanied by an EMT, with CIG on stand-by. The victim was reached and given aid. He eventually left the cave under his own power.
It may not apply to this situation, but be aware that a victim of hypothermia, if he is in an environment where he will continue to lose body heat while moving may be better off to stop. Movement for a hypothermia victim no longer produces much body heat and may use up the last of the victim's energy, causing death.
An experienced caver in Sullivan's Cave, Indiana, showed signs of advanced hypothermia and was assisted out of the cave by rescue personnel.
