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 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 11 Clinical Information Normal Body Temperature BT Normal BT is not a single temperature but a range of tem peratures influenced by age time of day and measurement site General Rule of Thumb Rectal temperature is 2 F 1 C higher than axillary and 1 F 0 5 C higher than oral temperature Expect the Differences Arterial temperature measurement PA Catheter TA Ther mometry leads all other methods in identifying fever or defer vescence and is unaffected by activities of daily living Ac cordingly 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 8 F 0 4 C higher than an optimum oral tem perature 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 Clinical Information 2 Fever Definition Clinically fever is defined as a BT 21 8 F 1 C above

10. lays 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 Itis 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 AHB automatically measures the temperature of the skin surface over the artery and ambient temperature synthesizing the two to produce arterial 4 About Temporal Artery Temperature temperature by sampling and calculating these paired readings some 5000 times with each use 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 Unique to infrared thermometry the instrument can be used with or without disposable covers thereby providing
