Frequently Asked Questions
False low readings:
•
Multiple readings can cool the skin, so if you take another
measurement immediately, expect a slightly lower reading.
•
Slide the thermometer straight across the forehead, not
down the side of the face where the TA could be embed-
ded under cartilage or fat.
•
Keep the probe flush on the skin, as in the picture on the
right. If angled, you will be measuring ambient air as well
as the TA area.
Memorable solutions?
•
Measure only the side exposed to the environment. The TemporalScanner as-
sumes the skin it measures has equilibrated to ambient, so a down or covered side
could be falsely high as heat is trapped and the skin is unable to equilibrate.
•
If the up side is not the side closest to you, try scanning from the hairline towards
the center of the forehead.
•
Scan slowly across the TA area; if you scan too quickly you can miss the peak.
Conditions that could affect a reading
•
Bandages or pressure dressings covering the
forehead
•
Forehead abrasions, burns, or sweat
•
Agitated or combative patient
•
Patient’s forehead in direct draft from vent
or fan
...and their solutions
•
If accessible and dry, measure on
the area behind the ear lobe only.
•
Consider using the alternate sites:
femoral artery, lateral thoracic, or
axillary areas.
•
Thermometer in different ambient tempera-
ture than patient, i.e. window ledge directly
exposed to hot sun or cold weather, or in
direct line of air conditioning or fan
•
The Temporal Scanner should be kept
in the same ambient temperature as
your patient. Each 10° difference in
ambient can cause a 1° error in the
reading.
