Introduction to Temporal Artery Thermometry

Introduction

The MeThe Me

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 addi-

tion, 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. Treat-

ment can be initiated sooner. We trust you will find temporal artery thermometry is simply a

better method.

sive, accurate method of thermometry. Oral thermometry is subject to many artifactual errors;

rectal temperature meets with strong resistance from patients, parents, and even many clini-

cians. 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 pediatric 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 rela-

tively constant perfusion rate, ensuring the stability of blood flow required for the measure-

ment method.

As a site for temperature measurement, the temporal artery presents many benefits: it poses

no risk of injury for patient or clinician, eliminates any need for disrobing or unbundling, and is

suitable for all ages.

LXTA/TAT-5000: To activate, press the red button once and release. The display will

TAT-4000: To activate, you should touch something >90ºF(32ºC) (skin) , press the

red button once and release. The display will remain on for 30 seconds.

Familiarize yourself with the Instrument

One of the most important features of the TAT thermometer is its ability to scan. It is a patented feature of the instrument. Scanning is critical in obtaining the correct temperature, since there are temperature gradients present not only inside the body, but across the entire surface of the body.

The object of scanning is to capture the highest temperature, the peak, in the area being scanned. As long as the button is depressed, the thermometer will be continually sampling and recording the highest temperature it measures.

Test it first on your hand to get comfortable with the concept.

Depress the red button, and keep it depressed. Scan the probe over the center area of your palm, keeping the probe about a half an inch off the surface to avoid cooling the skin.

LXTA/TAT-5000: Watch the display as the temperature increases in synchrony with the clicking. When

the numbers on the display stop increasing, the clicking also stops, indicating that the peak temperature has been reached.

TAT-4000 The display will flash SCAN, and there will be a soft but rapid clicking sound each time the

sensor detects a temperature higher than the one before. When the flashing and clicking slow to about 1 per second, the peak temperature has been reached.

Any of the above indications can be used to assure the peak temperature has been reached. Notice on the LXTA/TAT-5000 that the temperature only increases over the initial measurement. Once a peak has been measured, it is locked on the display , and will not change until a higher temperature has been measured.

Remove the instrument from your palm, release the button and note the reading on the display.

The reading will be locked on the display for 15 seconds on the LXTA/TAT-5000, and 30 seconds on the TAT4000, unless you press the button again before that time. Repeat the above steps and you should get the same, or very close to the same number, since your hand will usually not appreciably change temperature very quickly.

Practice Holding Your TemporalScanner

The TemporalScanner is ergonomically designed specifically for

its application. It’s best to hold the instrument with your thumb

on the red button, much like you would hold a remote control.

Along with allowing you to easily read the temperature display, you

will automatically be using finger dexterity to gently position the

probe, providing comfort and safety for your patient and consis-

tently accurate temperature readings.

Things To Know Before Taking Temperatures

• Measure only the exposed side. Anything covering the area

to be measured would insulate it and prevent the heat from

dissipating, resulting in falsely high readings. Brush hair aside

if covering the TA, or the area behind the ear.

• Slide the thermometer straight across the forehead (midline),

Familiarize Yourself with the Instrument

and not down the side of the face. Midline over the TA area,

the TA is less than 2mm below skin surface, whereas as the

TA winds down the side of the face it is further from the skin

surface. Although anatomically correct, sliding downwards

could result in falsely low readings.

• It is preferable to hold the instrument sideways, as illustrated

in Figure 2. Approaching your patient with the instrument

straight up and down could be somewhat intimidating.

• When making the measurement behind the ear as in Figure

3, tuck the thermometer under the ear lobe in the soft coni-

cal depression on the neck just below the mastoid. This is

the place where a dab of perfume is typically applied.

Using on an Infant

• An infant is apt to be presented bundled, with blankets and

clothing covering the neck area. Fortunately, the perfusion

rate is normally strong for infants, and unless visibly dia-

phoretic, one measurement at the TA is typically all that is

required.

Should you feel that the temperature is too low, push aside

any clothing or blankets covering the neck area for ~30

seconds or so and repeat the measurement behind the ear.
