Stages of Hypothermia

Stages of Hypothermia :


1	Body core temperature*	Shivering?	Impaired physical ability?	Altered mental state?	Unconscious?	Losing signs of life?	Status
2	°C	°F
3	37	98.6	No	No	No	No	No	Not hypothermic
4	37-36	98-96	Yes (increasing with cold)	No	No	No	No	Cold Stressed – Not Hypothermic
5	35-34	95-93	Yes (increasing more)	Yes	No	No	No	Mild Hypothermia
6	34-33	92-91		Yes	No	No
7	32-29	90-83	Shivering slows and stops	Little to no physical ability	Yes	No	Heartbeat and pulse becoming slow and/or irregular	Moderate Hypothermia
8	28-24	82-75	No	None	Yes -leading to lost reflexes	Yes	Decreasing signs of life including lost pain response	Severe / Profound Hypothermia
9	23-18	74-64	No shivering	None	No mental response	Yes	Heartbeat and breathing decline, pupils don’t respond to light, then heartbeat undectectable	Near Death or Death (Death cannot be known in the field; Many recover from very low body temp.)
