818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 5 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.

818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 7 • 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 818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 8 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.
818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 9 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.
Using the TemporalScanner on a New Mother 818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 10 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.
818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 11 • 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.
Frequently Asked Questions 818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 12 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.
818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 13 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 818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 14 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.
818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 15 • 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.
Guidelines for Patient Temperature Assessment 818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 16 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.

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.
Determining a Fever Threshold 818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 18 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.
818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 19 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 818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 20 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.
818528r5:818528r5.qxd 4/24/2008 11:04 AM Page 21 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.
Forgotten Physiology 818528r5:818528r5.qxd 4/24/2008 11:05 AM Page 22 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.
818528r5:818528r5.qxd 4/24/2008 11:05 AM Page 23 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.
818528r5:818528r5.qxd 4/24/2008 11:05 AM Page 24 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.
818528r5:818528r5.qxd 4/24/2008 11:05 AM Page 25 • 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.
Care and Maintenance 818528r5:818528r5.qxd 4/24/2008 11:05 AM Page 26 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.
