Consider the cause, such as exhaustion, weather, medical or trauma and attempt to deal with these conditions.
- If possible remove the person from the environment into a tent or shelter
- A warm drink can be provided, preferably without caffeine and not alcohol
- Hypoglycaemia is likely due to the energy consumed in shivering, so an intake of simple sugars and complex carbohydrates will increase glucose levels
- Insulate underneath with a foam mat
- Cover hands with gloves and the head with a hat or scarf
- Any exposed skin should be covered
- It may be possible to remove wet clothing and replace with dry if an adequate shelter is provided
For those with trauma involving bleeding, ensure all bleeding is treated and monitored. Any perosn who has experienced a life-threatening bleed is at risk of hypothermia, acidosis and coagulopathy. Coagulopathy is the inability of the blood to clot normally. This is know as the Lethal Triad in trauma patients.
