Body Core Temperature Assessment in Emergency Care Departments.

Background: There is concern that the values provided by devices using infrared thermometry in emergency departments (EDs) do not reflect body core temperature accurately.

Objectives: Evaluation of three thermometers commonly used in the ED.

Methods: Two infrared ear thermometers and an infrared forehead thermometer were evaluated using 1) the Voltcraft IRS-350 calibration device, 2) comparing temperature values to a rectal end-exercise temperature (T-RECT) of 38.
