Quick Answer
When assessing someone's condition with hypothermia, look for signs of altered mental status, such as confusion, loss of coordination, or slurred speech, along with physical symptoms like shivering, pale skin, and a slow or irregular heartbeat.
Recognizing Hypothermia
When assessing a potentially hypothermic individual, quickly check their vital signs, including body temperature, heart rate, and blood pressure. Use a digital thermometer to take their temperature, aiming for the armpit or ear canal. If their temperature is below 95°F (35°C), suspect hypothermia. Also, watch for signs of hypothermia’s progression, such as shivering (initial), apathy (moderate), and loss of consciousness (severe).
Assessing Mental Status
Altered mental status is a critical indicator of hypothermia, often appearing before physical symptoms. Ask simple questions like the person’s name, their location, or what they’re doing. Assess their level of consciousness using the Glasgow Coma Scale, which evaluates eye opening, verbal response, and motor response. A score below 15 indicates altered mental status.
Rewarming Techniques
To prevent afterdrop, rewarming should be gradual and carefully managed. Initially, remove any wet clothing and provide a warm, dry blanket or sleeping bag. Use passive rewarming techniques, such as sipping warm liquids or applying warm compresses to large muscle groups. Avoid direct heat sources, like stoves or fireplaces, which can cause burns. Use an electric blanket on a low setting if available, but never directly on the skin. Monitor the person’s temperature closely and adjust their rewarming technique as needed to prevent overshooting and potential further complications.
