Body Temperature - Vicks V980CA Use And Care Manual

How does Vicks Behind Ear Gentle Touch Thermometer Work?
The Vicks Behind Ear Gentle Touch Thermometer is a hand-held, battery
powered device designed to measure human body temperature with a
special sensor that accurately and gently detects heat flow through the skin
directly behind the ear lobe using the heat conduction effect and prediction
techniques. The thermometer calculates heat flow through the skin and by use
of a mathematical algorithm estimates the internal body temperature. The
temperature reading range of the thermometer is from 35.5°C to 42°C (95.9° F
to 107.6° F) and the reading time is about 1 second.
Why Measure Behind the Ear?
The skin area behind the earlobe is over the posterior auricular artery which
is a branch of the carotid artery. The carotid artery carries blood to the brain
and therefore this site is the best external place to measure temperature.

Body Temperature

Normal body temperature is not a single number – it's a range.
Many people incorrectly believe that 37°C (98.6°F) is the only normal
temperature. Yet, it's just an average number. Each person has their
own normal range which fluctuates throughout the day. It is, therefore,
important to determine your normal temperature range. A person's normal
(healthy) temperature range tends to decrease with age.
The following table shows that this normal range also varies by the
measurement site. Therefore, readings from different sites should not be
directly compared.
Normal temperature ranges by site:
Axillary :
1
Oral :
1
Rectal :
1
Ear :
2
Behind Ear:
Practice taking temperatures on yourself and family members to determine
their normal temperature ranges.
