Objectives
6.1.1 IDENTIFY, the three main factors that determine how long a person can stay alive in cold water.
6.1.2 DESCRIBE the preventive measures that can be used to increase the chances for successful cold water survival.
6.1.3 IDENTIFY the factors that increase the threat of hypothermia.
4
Objectives
6.1.4 IDENTIFY the signs of hypothermia.
6.1.5 IDENTIFY the treatment for hypothermia.
6.1.6 Given local water temperature tables, cold water survival table and job aid DETERMINE local survival times.
5
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.
6
Hypothermia Risk Factors
Factors that increase the risk of hypothermia;
1. Length of time exposed.2. Wind Chill Temperature3. Sea spray and rain.4. Clothing worn.
7
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

Glassy Stare
Apathy
Loss of consciousness

Treatment of Hypothermia
WARNING Any person pulled from cold water should be treated for hypothermia.
WARNING Do not give alcohol to anyone with hypothermia.
14
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.
15
Signs of Severe Hypothermia
May be unconscious.
May have slowed or stopped breathing.
May have slow and irregular pulse..
May feel stiff and rigid.
16
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.
17
Survival Techniques
Put on as much warm clothing as possible.
Wear PFD.
Avoid entering the water.
Before entering the water, button up clothing.

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.
