The Braun Thermoscan
®
system, PerfecTemp™, that overcomes the challenges presented by ear canal anatomy and
variations in technique among clinicians. The thermometer collects information about the direction
and depth of ear probe placement as it is placed into the ear canal and automatically incorporates
this information into the temperature calculation. Incorporating information related to patient
specific anatomy and exact ear probe placement in the ear canal increases the accuracy of the
measurement as compared to core temperature, especially when probe positioning is not ideal.
5.3 ExacTemp™ technology
The Braun Thermoscan
®
supports temperature measurement reliability by detecting the stability of the probe placement
during the measurement. The ExacTemp light flashes during the measuring process and remains
illuminated when the measurement is complete, indicating consistent placement of the probe
during the measurement process. Consistent probe placement helps support accurate temperature
measurement.
5.4 Why measure in the ear?
Clinical studies have shown that the ear is an excellent site for
temperature measurement because temperatures taken in the ear
reflect the body's core temperature
by the hypothalamus , which shares the same blood supply as the
2
tympanic membrane . Changes in core body temperature are usually
3
seen sooner at the tympanic membrane than at other sites, such as the
rectum, mouth or under the arm. Advantages of taking temperatures at
the ear versus traditional sites:
• Axillary temperature measurements reflect skin temperature which
may not reliably indicate the internal body temperature.
• Rectal temperatures often lag significantly behind internal body temperature changes, especially
at times of rapidly changing temperatures. Also, there is a risk of cross contamination.
• Oral temperatures are often influenced by eating, drinking, thermometer placement, breathing
through the mouth, or the inability of the person to close their mouth completely.
