TLDR

It determines temperature by measuring infrared radiation emitted by a warm object. We evaluated a new clinical thermometer for accuracy. The in‑vivo assessment was performed on ICU patients after open‑heart surgery. The thermometer was accurate in vivo and in vitro across 34.0–39.5 °C, closely tracked core temperature with a correlation of 0.98, measured in under 2 s, and was deemed easy to use clinically.

Abstract

We have evaluated a new clinical thermometer for accuracy. It determines temperature by measuring infrared radiation given off by a warm object. It was found to be accurate both in vivo and in vitro over the temperature range of 34.0° to 39.5°C. The in vivo assessment was made in patients in the ICU after their return from open heart surgery. The infrared tympanic thermometer tracked the core temperature (as measured by the thermistor tip of the pulmonary artery catheter) closely, with a correlation coefficient of 0.98, and took less than 2 sec to measure. We found this new thermometer to be accurate and, in our opinion, easily usable in the clinical situation.
