70 degrees is still in the cold water scenario so go for it.
We also extend the GOLDEN HOUR to 2 hours.
It isnt the hospital that is the problem but the way a few of the ER Docs think. I know one that feels that if you drown, you drown and there is no way back. Then there are others that will try and bring back a mummy.
We just hope the good ones are on when it happens.
There is a good older tape out on cold water drowning by the USCG and Dr. Nimerof (sp) Im at home and the tape is at work. I can get the title later if you want.
Here is a link with a lot of info on it that might worth sharing.

Just remember to look out for number one then do everything you can for the victim(s).
