How to manage Hypothermia
Hypothermia occurs when the body's ability to generate and conserve heat is overcome by heat loss.
The aged and children
poor nutrition, exhaustion
pre-existing of neuro-related disease such as Diabetes and Stroke
What to look for
Shivering, the first sign of body cooling. Cold and pale skin.
You should notice these signs are warning of beginning of hypothermia.
You can recover safely at this stage with shivering.
How measure body temperature
You don't need to measure body temperature.
As criteria, we can use the degree of consciousness, the presence or absence of shivering.
What to do if you have shivering
1. Protect from the wind and wetness, Move to a warm environment such as shelter, Insulate from the ground, Changing wet for dry clothes, Cover the people with a vapor barrier (such as a blue tarp, a large piece of plastic, large garbage bags etc.)
2. Need calories to gain heat, food intake, maintain of adequate nutrition. Vigorous shivering is a very important method for increasing heat production. Shivering should be fueled by calorie replacement.
3. Staying well hydrated, cold drink is fine, not necessary warm
4. Insulate the patient, including the head and neck. Apply heat to areas of high surface heat transfer including the underarms, sides of the chest wall, the neck and groin. Place the patient in a sleeping bag or blanket and provide close skin-to-skin contact with a warm body.
If shivering ceases, the core temperature drop abnormally fast and body functions shut down. Behavior changing from erratic to apathetic to unresponsive is serious sign.
What to do when shivering cease
Treat patients very gently, Handle very carefully.
The hypothermic heart is very prone to spontaneous fatal arrythmia due to any disturbance or movement.
Transfer to a medical facility as soon as possible.
If there is no way to get to a medical facility, should rewarm aggressively and handle gently. Insulate and apply heat to areas of high surface heat transfer including the underarms, sides of the chest wall, the neck and groin.
