See www.exergen.com/s Changing the Way the World Takes Temperature Safety Information READ ALL INSTRUCTIONS BEFORE USING Intended Use: The Exergen TemporalScanner is a handheld infrared thermometer used by medical professionals for the intermittent measurement of human body temperature of people of all ages, by scanning the forehead skin over the temporal artery. Intended users are physicians, nurses, and nursing assistants at all levels who normally provide patient care. The thermometer provides a peak temperature reading from plural readings during the step of scanning. Electronic circuitry processes the measured peak temperature to provide a temperature display based on a model of heat balance relative to a detected arterial temperature, the electronic circuitry computing an internal temperature of the body as a function of ambient temperature and sensed surface temperature. Training materials that are supplementary to this instruction manual are available at www.exergen.com/s, and recommended for first time users. TAT-2000 Series thermometers are used by medical professionals in clinical environments. Such medical professionals include physicians, nurses, nurses' aides, patient care technicians, and others who are trained to take the temperature of patients.

Temporal Artery Thermometry The temporal artery (TA) area has a long history of temperature assessment dating back thousands of years with recorded references to palpation of the head for fever assessment. Branching from the external carotid, the superficial TA courses within about a millimeter of the skin's surface over the lateral forehead, providing good heat conduction to the skin surface, is readily accessible, and provides no risk of injury from being touched. Since it is not an anastomosing vessel, perfusion remains high and stable, ensuring the reliability of conditions for the patented Arterial Heat Balance method to compute accurate temperatures. This new, superior class of thermometry has been shown to improve outcomes and reduce costs by noninvasively measuring temperature with a degree of clinical accuracy unachievable with other methods of thermometry. 3 Temporal Artery Thermometry What is arterial temperature? Arterial temperature is the same temperature as the blood flowing from the heart via the aorta. It is the best determinate of body temperature, and unaffected by the artifactual errors and time delays of oral and rectal methods. What is the TemporalScanner? The TemporalScanner is an infrared thermometer designed for non-invasive temperature assessment at the temporal artery (TA). It is a kinder, gentler way to take temperature, and a better method for patient and clinician alike. It is breakthrough technology. How does it work? Temperature is measured by gently stroking the TemporalScanner across the forehead, and includes a momentary touch of the probe to the neck area behind the ear lobe, to account for any cooling of the forehead as a result of diaphoresis. The patented arterial heat balance technology (AHBTM) automatically measures the temperature of the skin surface over the artery and ambient temperature, synthesizing the two to produce arterial temperature by sampling and calculating these paired readings some 5000 times with each use. 4 How accurate is it? It has been clinically proven in all departments for all patients in premier university hospitals and proven to be more accurate than ear thermometry. What are the benefits of TA thermometry? Besides the inherent accuracy, as a site for temperature measurement, TA presents many benefits: no risk of injury for patient or clinician, eliminates the need for disrobing or unbundling, and is suitable for all ages from preemies to geriatrics. Unique to infrared thermometry, the instrument can be used with or without disposable covers, thereby providing a substantial cost savings unavailable with other methods of thermometry. Product Map Probe Cone Probe Sensor Lens Probe LCD Display Screen LED Indicator Light Scan Button Automatic turn-off in 30 seconds LED Indicator Light Thumb-Push Ridges Battery Compartment for 9-volt battery Probe Caps & Dispenser TemporalScanner Model 2000 can be used either with disposable caps (Part No. 134203), or if preferred, without disposable caps by simply wiping the probe with alcohol or other disinfectant between patients. Disposable covers can be used once and discarded, or reused on the same patient. If using disposable caps, they are easily applied on the probe as illustrated in Figure 1, and easily ejected by a gentle push of your thumb as illustrated in Figure 2. 1 A convenient wall-mounted dispenser holding 100 disposable caps is available, 3 illustrated in Figure 3 (Part No. 134315). 2 Ancillary items, including disposable caps are available from many distributors, or by calling Exergen Customer Service at 1-617-923-9900, or by emailing service@exergen. com. 5 Measuring TA Temperature What you should know before using the TAT: · Measure only the side of the head exposed to the environment. Anything covering the area to be measured (hair, hat, wig, bandages) would insulate the area, resulting in falsely high readings. · Slide the thermometer straight across the forehead, not down the side of the face. Midline on the forehead, the TA is about a millimeter below the skin, whereas at the side of the face, the TA is much deeper, and measuring there would result in falsely low readings. · When taking a temperature behind the ear lobe, first push away any hair, exposing the area. Then, tuck the thermometer on the neck under the ear lobe, in the soft conical depression below the mastoid, (the place where perfume is typically applied). · Wait about 30 seconds before measuring the same patient again to avoid excessive cooling of the skin. · An infant frequently presents with blankets and clothing covering the neck area. Since the perfusion rate is normally strong for infants, and unless visibly diaphoretic, one measurement at the TA area is typically all that is required. Should you feel the temperature is low, then push aside any clothing or blankets covering the neck area for ~30 seconds or so, and repeat the measurement behind the ear. Brush hair aside if covering the TA area Place the probe flush on the center of the 1 forehead. Depress the Scan button, Keep depressed throughout 2 measurement... Slowly slide the probe midline across the forehead to the hair line 3 Brush hair aside if covering ear Lift probe from forehead and touch on the neck 4 just behind the ear lobe Release button, read and record · Display will remain for 30 seconds, before 5 automatic turn-off. · To turn off immediately, press and release · To restart immediately, depress button and continue as above 6 Measuring TA Temperature What else should I know? · A dirty probe lens and cone can cause a low reading. If not shiny, clean the lens and cone with an alcohol prep or a Q-tip moistened in alcohol. · It is preferable to hold the instrument sideways. Approaching your patient with the instrument straight up and down could be somewhat intimidating, especially to an agitated patient. · If you are right handed, you might find it easier to measure the left side of your patient; a left hander would find measuring the right side of the patient to be easier. · Consider holding the thermometer like a pencil or pen as illustrated. · If your patient is agitated, or squirms away before you have completed your measurement, just keep the button depressed and you can continue the measurement without having to wait. Why measure behind the ear lobe (BE) as well as the temporal artery? To avoid any possibility of false low temperature caused by diaphoresis, which many times is not obvious. Think of it as a touch of insurance. How does diaphoresis affect readings? Moisture cools the skin over the temporal artery area. Why behind the ear lobe? If your patient is sweaty, vasodilation will always be present, and blood flow BE will be as high as the TA area were it dry. What if the TA area has been traumatized by burns or lacerations, or is completely covered with dressings? With head trauma, surgical or accidental, the temperature can be obtained from the alternative site on the neck BE. Just as with diaphoresis, the perfusion will be high. Why not use the area BE as a sole site? Without diaphoresis or head trauma, this area is just too variable to be reliable as a sole site. 7 Clinical Information Normal Body Temperature (BT) Normal BT is not a single temperature, but a range of temperatures influenced by age, time of day, and measurement site. General Rule of Thumb Rectal temperature is 1°C (2°F) higher than axillary and 0.5°C (1° F) higher than oral temperature.1 Expect the Differences Arterial temperature measurement (PA Catheter, TA Thermometry) leads all other methods in identifying fever or defervescence, and is unaffected by activities of daily living. Accordingly, it will sometimes be different from your present methods -- but accurate. Guidelines for Patient Temperature Assessment 1. Normal TA Temperature: On a stable resting patient, TAT is 0.4°C (0.8°F) higher than an optimum oral temperature, and is about the same as a rectal temperature. However, during febrile episodes, the difference can be much higher, mainly because of the artifacts of oral and rectal sites. 2. Fever Definition: Clinically, fever is defined as a BT 1°C (1.8°F) above the mean standard deviation at the site of recording.2 A single oral temperature of 38.3°C (101°F) in the absence of obvious environmental causes is usually considered fever. An oral temperature of 38.0°C (100.4°F) over at least 1 hour indicates a fever state.3 8 A single arterial temperature > 38.8°C (101.8°F) in the absence of obvious environmental causes is usually considered fever. An arterial temperature > 38.4°C (101.2°F) over at least 1 hour indicates a fever state. While the above are recommended guidelines, not all fevers require laboratory tests, and clinical assessment in concert with standard hospital protocol for fever workups should always prevail. 3. Oral Temperature Risks: Oral temperature can be clinically misleading, and many febrile patients can have a "normal" temperature.4 Mouth breathing, tachypnea, heated gases, and hot or cold fluids can distort the reading, as can intubation or inability of the patient to cooperate. Accordingly, comparisons with TA may not be reliable. Normal Body Temperature Ranges at Various Measurement Sites: Arterial: 36.3-37.8°C 97.4-100.1°F Oral: 35.9-37.5°C 96.6-99.5°F Esophageal: 36.9-37.8°C 98.4-100.0°F Rectal: 36.5-37.9°C 97.7-100.3°F Axillary: 35.3-37.1°C 95.5-98.8°F Oronasal: 35.9-37.2°C 96.6-99.0°F Clinical Information 4.

Laboratory testing protocol for laboratory accuracy available upon request. 9 Cleaning the Instrument The TemporalScanner is an optical instrument. Like a camera or eye glasses, a dirty lens will distort the view. If the thermometer is unable to see the heat clearly, it will be unable to measure it accurately, resulting in low readings. Probe lens and cone should be shiny clean, if not, wipe with an alcohol prep, or with a swab moistened in alcohol or water. Do not hold the TemporalScanner under the faucet or submerge in water. It is not waterproof. Hold upside-down to prevent excess moisture from entering the sensor area. It will not harm the sensor, but if it becomes too wet, you will be unable to take a temperature until it dries. Thermometer case can be cleaned with any hospital approved disinfectant, alcohol, even bleach solutions. Avoid gritty, abrasive cleaners as they can scratch the thermometer. Changing the Battery Blinking battery icon with temperature displayed: battery is low but will still operate correctly. Replace soon.
