Why measure behind the ear lobe (BE) as well as the
temporal artery?
To avoid any possibility of false low temperature caused
by diaphoresis, which many times is not obvious. Think
of it as a touch of insurance.
How does diaphoresis affect readings?
Moisture cools the skin over the temporal artery area.
Why behind the ear lobe?
If your patient is sweaty, vasodilation will always be pre-
sent, and blood flow BE will be as high as the TA area
were it dry.
What if the TA area has been traumatized by burns or
lacerations, or is completely covered with dressings?
With head trauma, surgical or accidental, the temperature
can be obtained from the alternative site BE. Just as with
diaphoresis, the perfusion will be high.
Why not use the area BE as a sole site?
Without diaphoresis or head trauma, this area is just too
variable to be reliable as a sole site.
