Hypothermia
Diagnosis of Hypothermia
Measurement of body temperature Sometimes tests for other disorders Health care providers diagnose hypothermia by measuring a body temperature less than 95° F (35° C), typically with a rectal thermometer. Conventional thermometers do not record temperatures below 94°F (about 34°C). Thus, electronic thermometers are needed to measure temperatures in severe hypothermia. Blood and sometimes other tests are done to see whether a disorder such as an infection or hypothyroidism caused hypothermia. If a person has no signs of life, health care providers may use cardiac ultrasonography to determine whether the heart is still beating.
