Sorry it took so long to reply, thanksgiving festivities have kept me busy the last couple days.
While I agree this could have made a great thread/debate on it's own, maybe it's just me but, it seems like it would be a little redundant as it's
already been played out here.
Apologies, to asala if you feel we've hijacked your thread.
There are many factors that affect survivability in cold water near drownings (age, health, water temp, duration of submersion) but without a doubt,
children have the best chances of survival in extended submersion scenerios.
This could be due to the resiliency of youth, a lesser body mass allowing for quicker cooling, or the combination of both plus other factors.
For those following along (
sometimes I forget there's an "audience"
) I've dug up a few more links.
Journal of the American Medical Association
October 28, 1992
"Severe accidental hypothermia (body temperature below 30° C (86° F]) is associated with marked depression of cerebral blood flow and oxygen
requirement, reduced cardiac output, and decreased arterial pressure.
Victims can appear to be clinically dead because of marked depression of
brain and cardiovascular function, but
full resuscitation with intact neurological recovery is possible, although unusual. The victim's
peripheral pulses and respiratory efforts may be difficult to detect, but
lifesaving procedures should not be with held based on clinical
presentation."
"pulse and respirations may need to be checked for longer periods to detect minimal cardiopulmonary efforts"

STATE OF ALASKA COLD INJURIES AND COLD WATER
NEAR DROWNING GUIDELINES (Rev 01/2005)
"1. Hypothermia provides some temporary protection from the effects of cardiopulmonary arrest and
prolongs the possibility of normal
recovery"
"2. Because of the protective effect of severe hypothermia, resuscitation efforts should
not be discontinued according to the same time
criteria used for normothermic patients."

"D. If a person has been under water for less than one hour, full resuscitative efforts should be employed."
"F. If the length of time under water is unknown, it should be considered to have been less than one hour unless there are obvious signs of long
submersion including slippage of skin or animal predation."
"I. The difference between warm and cold water is that in submersions greater than 6 minutes, the chance for survival in warm water is much less than
in cold water.
The colder the water, the better the chance for survival."

Please understand, none of this was meant to be an attack on you; lifesaving is a noble cause in any form, and for all I know, you live in a warm
climate where it's not relevant or considered "need to know" material.
In the north and midwest, where we have ice fishing accidents and other situations on a yearly basis, it is far more nescessary to learn about these
types of scenerios.
If you still think a debate is nescessary, let me know, but like I said, I think it might be a bit redundant just to rehash what we've already
posted.

don't hate me!
Nah, I don't "hate" anyone here, in fact, it was a
great idea.
I always forget that they sponsor debates in their own separate forum here.
However, (and maybe I'm alone in this opinion) like I've stated, in this instance it feels like it would suffer from the old "beating a dead
horse" syndrome.
I'll definately have to keep that option in mind for future reference though.
