Development of a Rapid, Noninvasive Core Temperature Measurement Device. Phase 1.
Abstract
The rapid, noninvasive measurement of core temperature in humans is desireable since both elevated core temperature (hyperthermia) and depressed core temperature, including oral and rectal thermometry, are unacceptable for field core estimation because of both physical and cultural problems. A rapid, noninvasive means of determining core temperature would be beneficial for in field management of combat casualties, as well as in peace-time evaluations of military materiel and physical workload assessments. In this Phase I SBIR effort, we have identified a new approach to rapidly and noninvasively measuring core temperature. We have established a relationship between exhaled air temperature, effective ambient temperature, and core temperature. In this relationship, the effective ambient temperature is the ambient air temperature corrected for wind velocity ( wind chill ), humidity, and air density. The results of our Phase I experiments indicate, that it is feasible to determine core temperature can be determined within 0.5 C of the temperature measured by an ingestible thermometry pill.
