Hypothermia
Hypothermia is defined as the loss of
internal body temperature.
Mild hypothermia if core temperature
falls below 98 F.
Severe hypothermia can cause
unconsciousness or death.
5
Hypothermia Risk Factors
Factors that increase the risk of
hypothermia;
1. Length of time exposed.
2. Wind Chill Temperature
3. Sea spray and rain.
4. Clothing worn.
6
Survival Factors
The length of time a person can
survive in cold water depends on
three main factors;
1. Temperature of the water.
2. Physical condition of survivor.
3. Actions taken by survivor.

Signs of Hypothermia
Shivering
Numbness
Glassy Stare
Apathy
Loss of consciousness
12
Treatment of Hypothermia
WARNING Any person pulled from cold
water should be treated for hypothermia.
WARNING Do not give alcohol to
anyone with hypothermia.
13
Treatment of Hypothermia
Care for life-threatening problems.
Move to warm place.
Remove wet clothing and dry.
Warm slowly.
Wrap in blankets/dry clothing.
If alert, give warm liquids.
Handle gently.
14
Signs of Severe Hypothermia
May be unconscious.
May have slowed or stopped
breathing.
May have slow and irregular pulse..
May feel stiff and rigid.
15
Treating Severe Hypothermia
Treat very gently.
Transport to a medical facility as quickly
as possible.
Keep checking pulse and respiration.
Be prepared to give rescue breathing and
CPR.
Continue to warm.
16
Survival Techniques
Put on as much warm clothing as
possible.
Wear PFD.
Avoid entering the water.
Before entering the water, button up
clothing.

Escape
Lessening
Position
 Cross arms & keep elbows
close to your side.
 Cross your legs & bring
knees to your chest.
 Keep head & neck out of
the water.
 Works best when wearing a
PFD.
