Learning Intention:
To equip you with the knowledge to avoid, recognise and treat mild hypothermia.
![Page 4: Mountain Safety. MS 1_7: FA Basics (Hypothermia)](https://reader036.vdocuments.us/reader036/viewer/2022062318/551ac78d5503466b6a8b5010/html5/thumbnails/4.jpg)
Success Criteria:By the end of this session everyone should be able to:• Describe what steps to take to avoid,
recognise and treat mild hypothermia in a wilderness environment.
Some of you may be able to:• Recognise and treat severe hypothermia.

What can make your body cold?

How does your body respond to
cold?
![Page 9: Mountain Safety. MS 1_7: FA Basics (Hypothermia)](https://reader036.vdocuments.us/reader036/viewer/2022062318/551ac78d5503466b6a8b5010/html5/thumbnails/9.jpg)
Stage 1: The Cold Response
• The body’s normal response to a cold challenge:– Blood is shunted from the periphery (e.g. feet,
hands, ears, nose, skin) to the core;– Mild shivering;– Fine motor function (e.g. movement of fingers)
may be impaired;– Increased urination.

What should you do?
![Page 11: Mountain Safety. MS 1_7: FA Basics (Hypothermia)](https://reader036.vdocuments.us/reader036/viewer/2022062318/551ac78d5503466b6a8b5010/html5/thumbnails/11.jpg)
What to do if you are feeling cold
• Add more clothing layers (Heat Retention)• Get into shelter (Heat Retention)• Increase fluid/fuel intake (Heat Production)• Increase exercise (Heat Production)
• EASILY DEALT WITH IF RECOGNISED EARLY.

Stage 2: MILD HYPOTHERMIA
– THE BODY’S ABILITY TO RESPOND TO COLD IS OVERWHELMED
– The onset of mild hypothermia is a field emergency, indicating a significant drop in core temperature has already occurred.

The "umbles"
• stumbles • mumbles • fumbles • grumbles

MILD HYPOTHERMIATreatment
• Shelter from wind and moisture• Remove wet clothes & replace with dry.• Body to body contact may be helpful• Insulate from the ground or snow
• Take in fluids (warm drinks)• Take in Calories• Exercise to increase heat production only
once above completed.

Stage 3: SEVERE HYPOTHERMIA
• This is a true medical emergency (but should not happen if dealt with early in Stage 1/2)
• The patient has lost all ability to fight the cold. Rescue efforts should be directed to preventing further heat loss and immediate evacuation.
![Page 18: Mountain Safety. MS 1_7: FA Basics (Hypothermia)](https://reader036.vdocuments.us/reader036/viewer/2022062318/551ac78d5503466b6a8b5010/html5/thumbnails/18.jpg)
SEVERE HYPOTHERMIA
• Shivering stops• Unconsciousness• Apparent death• Death

SEVERE HYPOTHERMIATreatment
• No food/drink if unconscious• Reduce further heat loss.• Package casualty• Handle gently• Prevent exercise• Avoid rewarming

SUMMARY
• Easily treated on the hill if recognised early
• Keep an eye on your group• If left, can become life-threatening
