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.

• To Scan: Depress the red button. The instrument will continually scan for the highest temperature (peak) as long as the button is depressed. • Clicking: Each fast click indicates a rise to a higher temperature, similar to a radar detector. Slow clicking indicates that the instrument is still scanning, but not finding any higher temperature. • To Retain or Lock Reading: The reading will remain on the display for 30 seconds after button is released.
Familiarize Yourself with the Instrument 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 consistently accurate temperature readings.
Measure only the exposed side. Brush hair aside if covering the TA area. Brush hair away if covering ear. 1. With probe flush on the center of forehead, depress red button, keep depressed… 3. Lift probe from forehead and touch on the neck just behind the ear lobe. 2. Slowly slide probe midline across forehead to the hair line, not down side of face. 4. Release the button, read, and record temperature. Alternate sites when TA or BE are unavailable: • Femoral artery: slowly slide the probe across groin.
Using the TemporalScanner on a New Mother Using the TemporalScanner on a New Mother • Measure exposed skin • Keep the red button depressed throughout measurement (Brush bangs aside if present) 1. With probe flush on center of forehead, depress red button. 2. Slowly slide probe across the forehead into the hair line. 3. Lift probe from forehead. (Brush hair away if covering ear) 4. Touch probe to neck just behind the ear lobe. 5. Release button, read, and record temperature.
• Instrument should be in same temperature environment as the baby for approximately 20 minutes. • Measurement site must be exposed. • One measurement, preferably at the TA, is all that is required. Temporal artery area is the only option in this case, as the neck area is not exposed. Preferred site is the temporal artery area. In this case, behind the ear could be alternate site, as both are exposed. Temperature at the Temporal Artery Area 1) Gently touch probe to center of forehead.
Frequently Asked Questions Frequently Asked Questions What is the TemporalScanner? The TemporalScanner is an infrared thermometer designed for accurate, completely non-invasive temperature assessment by scanning the temporal artery (TA). It is breakthrough technology.
Since the arterial branch is deeper behind the ear lobe than at the temple, under normal conditions it is less accurate because of its variability. But under diaphoretic conditions, the blood flow behind the ear lobe is as high as at the TA, making it as accurate as the TA, but only during diaphoresis or with head trauma as previously mentioned.
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 embedded 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.
• TAT-5000 can be used with either disposable caps or full sheath. Can be used without disposables if terminally cleaned between patients. • Can be cleaned with any hospital approved disinfectant, alcohol, and even bleach solutions. Use only alcohol solution for sensor lens. • ”bAtt” on the display indicates a low battery. Replace with a 9-volt alkaline battery. • Probe lens should be shiny clean. If not, wipe with an alcohol prep or Qtip dipped in alcohol.
Guidelines for Patient Temperature Assessment Guidelines for Patient Temperature Assessment Comparing with Other Methods of Thermometry: Expect the Differences Unless you are using PA catheters or Exergen aural thermometers with AHB for temperature assessment, expect to see differences compared to your current thermometers. Arterial temperature measurement leads all other methods in identifying fever or defervescence, and is unaffected by patient activity.
1. Fever Definition: Clinically, fever is defined as a BT =1.8°F (1°C) above the mean standard deviation at the site of recording.2 A single oral temperature of 101°F (38.3°C ) in the absence of obvious environmental causes is usually considered fever. An oral temperature of 100.4°F (38.0°C) over at least 1 hour indicates a fever state.3 2. Oral Temperature Risks: Oral temperature can be clinically misleading, and many febrile patients can have a “normal” temperature, even when tachypnea was unobserved.4 3.
Determining a Fever Threshold Determining a Fever Threshold for Temporal Artery Thermometry Threshold Defining Fever • A threshold for defining fever is the temperature level above which false positives due to normal variations in temperature, including range of normal mean + circadian effects + other effects (metabolic, ovulation, etc.) are unlikely. Threshold for Fever Workup • Not all fevers require a fever workup.
An Overview of Temperature Measuring Sites Oral Temperature Oral temperature measurement is by far the most common clinical method in use today, and is responsible for masking the greatest number of fevers. Oral temperature can be misleadingly lowered by patient activity such as tachypnea, coughing, moaning, drinking, eating, mouthbreathing, snoring, talking, etc. Alarmingly, another cause of low oral temperatures is the fever itself. For each 0.
Body Sites for Temperature Assessment Under certain conditions, rectal temperature is even contraindicated; for example, severe arterial insufficiency in one or both legs might be associated with falsely low readings, or in conditions affecting peripheral blood flow such as cardiogenic shock. More common contraindications include neutropenia, severe hemorrhoids, and recent anorectal surgery.
Multiple temperature readings in the same area, mouth, rectum, axilla, ear or temporal artery, make for variability with each separate measurement. This can be confusing for clinicians, since they expect the same number with each measurement. The non-reproducibility of the readings, however, is not a function of the devices, but simply a function of physiology. The human body is a myriad of small gradients, and variability of readings will occur on every method of temperature measurement.
Forgotten Physiology Your Temperature Normal Temperature Normal human temperature is around 98.6 degrees. But did you know that only 8% of the people in the world have a normal temperature of exactly 98.6? A temperature that is normal for you may even be a whole degree or so above or below "normal." It is good to know what is normal for you. Try taking your temperature at different times, like in the morning, after a cold shower, or a five-mile hike.
The TemporalScanner relies on the skin over the temporal artery to help provide an accurate body temperature. In fact, it is measuring the inside by measuring the outside. Your skin is a sensor, controlling body temperature in two ways: radiation and evaporation. Since most of us don’t think about our skin as a sensor, this might be a good time to discuss a little physiology. We live our entire lives with a body temperature that changes only a few degrees.
For Kids Only Did you know you always have a temperature? Bet you thought you only had a temperature when you were sick. Absolutely everything has a temperature, even icicles. Brrrrrr! When you don't feel well, your mom or a nurse might say "let's see if you have a temperature," but what they really mean is "let’s see if your temperature is different from normal." So, when you have your temperature taken, don't be fooled.
• Battery: A standard alkaline 9V battery provides approximately 15,000 readings. ** To replace, loosen the single screw at the bottom of the instrument and remove the battery cover. Disconnect the old battery and replace with a new one in the same location. Replace the cover, and tighten the screw. Use only high quality alkaline batteries or equivalent. • Handling: The TemporalScanner is designed and built to industrial durability standards in order to provide long and trouble-free service.
Care and Maintenance Instructions for Fahrenheit or Celsius Conversion The TemporalScanner can be used in either °F or °C. To convert from one scale to the other, the only tool necessary is a paper clip or the tip of a small screwdriver. For °F/°C Conversion: o F • Loosen single screw on bottom of case and remove battery cover. Switch • Lift battery out of the way.
Care and Maintenance *Automatically applied when temperature is within normal body temperature range, otherwise reads surface temperature. ** Approximate number of readings when scanning for 5 seconds and reading the temperature display for 3 seconds before turning thermometer off.
Care and Maintenance Using the Portable Blackbody 1. Turn on the verifier device, using either a 9-volt battery or the power supply. Make sure the red LED is illuminated. 2. Allow device ~5 minutes for warm-up and stabilization time. 3.
