The non invasive accurate measurement of core body temperature is a surprisingly complex technical challenge. A comparison of axilla tympanic membrane and pulmonary artery blood temperature.
Greenteg Core Body Temperature Core Body Temperature
Non invasive measurement of core body temperature. Long term accurate measurements of core body temperature are essential to study human thermoregulation in ambulatory settings and during exercise but they are traditionally carried out using highly invasive techniques. An insulator patch applied to the lateral forehead and covered by an electric heater is used to stop surface convection creating an isothermic tunnel from the core body to the skin surface. Fulbrook p 1997 core body temperature measurement. Journal of clinical nursing. In intensive care patients the pulmonary artery pa temperature which reflects the core temperature is considered the standard for comparison. Greenteg offers the worlds first core body temperature sensor for continuous and non invasive measurements.
We conducted two human subject studies with different experimental protocols different environmental temperatures 10 c 30 c and different subjects. The miniaturized sensor is ideal for the integration into wearable and med tech devices with skin contact. Hence the device chosen should combine four elements. Table 1 summarizes studies evaluating the agreement of various non invasive temperature measurement methods oral ear based temporal artery and axillary with the pa temperature. Core body temperature is an important vital parameter to determine the health status of a person. D 19148 2015 tcore a new non invasive technology.
However because of the potential benefits for both patients and hospitals dräger was eager to take on the challenge. Wearable non invasive and capable of performing continuous and accurate measurements during free living conditions. The direct measurement of the temperature of the human body core while being of great significance for the evaluation of patient health is inconvenient. Comparison of non invasive methods in critical care. The dräger double sensor ds is a novel device for assessing body core temperature tc. Farnell s et al 2005 temperature measurement.
To enable a continuous unobtrusive monitoring of core body temperature on ambulatory patients and exercising athletes we have designed a wireless wearable system that measures the tympanic. In both studies the same non invasive measurement methods skin. Relevant non invasive measures to predict core body temperature under various conditions. The purpose of this study was to evaluate the accuracy of the ds in measuring tc under heat stress. Core is the first device that combines a non invasive wearable with continuous measurements of body temperature under real life conditions with great accuracy. In human medicine a non invasive method to accurately evaluate core body temperature is the zero heat flux zhf technology first described in 1973.
This realization has motivated attempts to measure the core temperature indirectly for the most part at locations which do not require invasion of the body. Non invasive measurement of core body temperature in marathon runners.
