The document discusses cold water survival and rescue. It notes that hypothermia is not the primary threat in cold water immersion situations, but rather cold shock and incapacitation are larger risks in the first 10 minutes. It then outlines the effects of cold water immersion over time, including cold shock, cold incapacitation, and hypothermia. The document promotes a hands-on educational course on cold water survival and rescue techniques for first responders and recreational boaters.

1. The National Water Safety Congress Presents

4. Question on Survival If you fell in ice water in normal clothing, how long do you think you would last before you became hypothermic?

5. Hypothermia – professionals Estimates from 480 medical, paramedical and SAR personnel on how long a person can survive in ice water % minutes

6. Hypothermia – REALITY An hour or more may be required for a person to become unconscious due to hypothermia IF a lifejacket or some other device eliminates the need for vigorous exercise and the airway is kept clear to keep from drowning. Another hour before the heart stops.

7. So Why Should We Care?

8. … Because accidents like these are happening all the time…it’s your job to be ready for them

9. Some drowning stats 2006 U.S. Drownings In water under 49 F / more than 50% of all boating accidents had a fatality U.K. / Dr. M. Tipton 55% drowned within 10 feet of safety Lifesaving Study / Canada 2000 – 2004 Boaters 60% drowned in water under 50 F 38 % in water 50 - 70 C 43 % were less than 6 feet from safety

19. There is a risk of heart failure due to cold shock particularly if the person has an underlying heart condition. Cold Shock Induced Heart Failure

20. Cold Shock Induced Heart Failure

21. Cold Incapacitation 1 - 10 – 1 You have 10 minutes of meaningful movement to self rescue or prepare to wait it out to be rescued.

24. Cold Incapacitation

25. Hypothermia 1 - 10 – 1 Even in ice cold water (32 degrees F), an hour or more may be required for a person to become unconscious due to hypothermia IF a lifejacket or some other device eliminates the need for vigorous exercise to keep from drowning.

26. Hypothermia Once a victim is unconscious, another hour or more may be required for the heart to stop if the head is kept above water (lifejacket worn) and the water is calm enough for waves not to wash over the mouth.
