Hypothermia/Frostbite
In conditions of prolonged cold exposure, your body sends signals to the blood vessels in your arms and legs telling them to constrict (narrow). By slowing blood flow to the skin, your body is able to send more blood to the vital organs, supplying them with critical nutrients.
Frostbite occurs when tissues freeze. This condition happens when you are exposed to temperatures below the freezing point of skin.
The nose, cheeks, ears, fingers, and toes (your extremities) are most commonly affected.

Hypothermia/Frostbite
Frostbite is caused by 2 different means: cell death at the time of exposure and further cell deterioration and death because of a lack of oxygen.
In the first, ice crystals form in the space outside of the cells. Water is lost from the cell’s interior, and dehydration promotes the destruction of the cell

Hypothermia/Frostbite
In the second, the damaged lining of the blood vessels is the main culprit. As blood flow returns to the extremities upon rewarming, it finds that the blood vessels themselves are injured.

STAGES OF HYPOTHERMIA
98 - 95 degrees - Sensation of chilliness, skin numbness; minor impairment in muscular performance, especially in use of hands; shivering begins.
95 - 93 degrees - More obvious muscle in coordination and weakness; slow stumbling pace; mild confusion and apathy. Skin pale and cold to touch.
93 - 90 degrees - Gross muscular in coordination with frequent stumbling and falling and inability to use hands; mental sluggishness with slow thought and speech; retrograde amnesia.
90 - 86 degrees - Cessation of shivering; severe muscular in coordination with stiffness and inability to walk or stand; incoherence, confusion, irrationality.
86 - 82 degrees - Severe muscular rigidity; patient barely arousable; dilatation of pupils; weak heartbeat and pulse. Skin ice cold.
82- 78 degrees and below - Unconsciousness; death due to cessation of heart action

Heat Exhaustion/Stroke
♦Physical stress placed on the body by overheating.
♦Symptoms: heavy sweating, cold, clammy skin, confusion/dizziness, nausea, weak, rapid pulse.
♦Treat by removing person from heat source. Use a fan or cold water to bring body temperature back to normal.
