What is Hypothermia?

Hypothermia occurs when body temperature falls below 95 degrees Fahrenheit. Visible warning signs include uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness, and exhaustion.

The U.S. government’s Occupational Safety & Health Administration (OSHA) recommended steps for a person suffering from hypothermia:

  • Call 911 immediately in an emergency; otherwise seek medical assistance as soon as possible.
  • Move the person to a warm, dry area.
  • Remove wet clothes and replace with dry clothes, cover the body (including the head and neck) with layers of blankets; and with a vapor barrier (e.g. tarp, garbage bag). Do not cover the face.
  • If medical help is more than 30 minutes away:
    • Give warm sweetened drinks if alert (no alcohol), to help increase the body temperature. Never try to give a drink to an unconscious person.
    • Place warm bottles or hot packs in armpits, sides of chest, and groin. Call 911 for additional rewarming instructions.
  • If a person is not breathing or has no pulse:
    • Call 911 for emergency medical assistance immediately.
    • Treat the worker as per instructions for hypothermia, but be very careful and do not try to give an unconscious person fluids.
    • Check him/her for signs of breathing and for a pulse. Check for 60 seconds.
    • If after 60 seconds the affected worker is not breathing and does not have a pulse, trained workers may start rescue breaths for 3 minutes.
    • Recheck for breathing and pulse, check for 60 seconds.
    • If the worker is still not breathing and has no pulse, continue rescue breathing.
    • Only start chest compressions per the direction of the 911 operator or emergency medical services*
    • Reassess patient’s physical status periodically.
