Ear Thermometer Advantages
Infrared Ear Thermometer measures core body temperature,
which is the temperature of a body's vital organs. (See Figure 1)
Ear temperatures accurately reflect core body temperatures since
the eardrum is in the cranial cavity and is not affected by the
environment. The eardrum shares blood supply with the
hypothalamus (part of the brain.) Therefore, body temperature
changes are reflected sooner in the ear than they are in other
parts of the body.

Ear Thermometer Advantages
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. Body temperature is regulated
by the hypothalamus, which shares the same blood supply as the
tympanic membrane. Changes in core body temperature are usually
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 other sites:
Axillary temperature readings only reflect skin temperature
●
which may not indicate the internal body temperature.
Rectal temperatures often lag significantly behind internal body
●
temperature changes, especially at times of rapidly changing
temperatures.
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.
