Introduction to Temporal Artery Thermometry
The Method
Temporal artery thermometry (TAT) is a completely new method of temperature
assessment, using infrared technology to detect the heat naturally emitting from
the skin surface. In addition, and of key importance, the method incorporates a
patented arterial heat balance system to automatically account for the effects of
ambient temperature on the skin.
This method of temperature assessment has been shown to improve results
and reduce costs by non-invasively measuring body temperature with a degree
of clinical accuracy unachievable with any other thermometry method.
Temperatures are more reliable than with other methods. Fevers are identified
sooner. Treatment can be initiated sooner. We trust you will find temporal
artery thermometry is simply a better method.
Why the Temporal Artery
The TAT method was developed in response to the clinical requirements for a
truly non-invasive, accurate method of thermometry. Oral thermometry is sub-
ject to many artifactual errors; rectal temperature meets with strong resistance
from patients, parents, and even many clinicians. Ear thermometers, although
convenient, are sensitive to technique. Some brands are known to miss fevers,
and it’s difficult to consider the use of an aural thermometer when 95% of pedi-
atric visits concern ear infections.
A site for detecting fevers with roots dating back to centuries before Christ, the
temporal artery demonstrated the necessary requirements to meet the stringent
demands of clinical medicine today: it is easily accessible, contains no mucous
membranes, and notably, maintains a relatively constant perfusion rate, ensur-
ing the stability of blood flow required for the measurement method.
As a site for temperature measurement, the temporal artery presents many ben-
efits: it poses no risk of injury for patient or clinician, eliminates any need for dis-
robing or unbundling, and is suitable for all ages.
