Quick Answer
A hypothermic person can self-treat in the field to some extent, but it is essential to take immediate action to prevent further heat loss and potential complications. Basic interventions can include removing wet clothing, seeking shelter, and using insulation. However, severe cases often require medical attention.
Initial Recognition and Response
Recognizing hypothermia in the field is critical. Look for symptoms such as shivering, confusion, dizziness, and poor judgment. If you suspect hypothermia, act quickly to prevent further heat loss. Remove wet clothing, and replace it with dry, insulating layers. Use a hat, gloves, and gaiters to prevent heat loss from the head, hands, and feet. The goal is to warm the person slowly and safely.
Rewarming Techniques
There are several rewarming techniques to consider in the field. The “buddy warming” method involves using the body heat of a companion. This can be done by having the person sit in the middle of two people, with the others wrapping their arms around them. The “hot water bottle” method involves filling a bottle with hot water, wrapping it in a towel, and placing it near the person’s core. Avoid using direct heat sources, such as a flame or electric heating pad, as they can cause burns or afterdrop.
Afterdrop and Severe Cases
Afterdrop occurs when the body core temperature drops further after rewarming has begun. This can be a sign of severe hypothermia. If the person’s core temperature drops below 90°F (32°C), they may experience cardiac arrest, seizures, or even death. In severe cases, seek immediate medical attention. If you cannot access medical care, continue rewarming the person slowly and carefully, using insulation and body heat. Monitor their vital signs closely, and be prepared to perform CPR if necessary.
