Quick Answer
Core body temperature above 35°C (95°F) is generally considered normal, while temperatures between 32°C (90°F) and 35°C (95°F) indicate mild hypothermia. Between 28°C (82°F) and 32°C (90°F), it's moderate hypothermia, and below 28°C (82°F), it's severe. In extreme cases, hypothermia can be fatal.
Recognizing Hypothermia
Hypothermia can be challenging to diagnose, especially in its early stages. Look for symptoms such as shivering, confusion, slurred speech, and difficulty with coordination. These signs may be masked in people with certain medical conditions, such as diabetes or heart disease. Always check for a decreased level of consciousness, as it’s a critical indicator of severe hypothermia.
Hypothermia Rewarming Techniques
When treating hypothermia, it’s essential to rewarm the body slowly and carefully to avoid causing afterdrop. Afterdrop is a sudden drop in body temperature that can occur when rewarming too quickly. To prevent afterdrop, use the “Buddy Method” where one person provides passive rewarming by lying with the hypothermic person, sharing body heat without direct skin contact. If possible, use a warm blanket or emergency blanket to cover the person, rather than direct heat sources like heaters or hot water bottles.
Severe Hypothermia Cases
In severe cases of hypothermia, the rewarming process should be done in a hospital setting with medical supervision. Administer warm IV fluids at 38°C (100°F) to 40°C (104°F) to help rewarm the body from the inside out. Do not use warm water baths or showers, as they can lead to afterdrop. In extreme cases, cardiac arrest may occur, and CPR should be performed immediately.
