• Follow the battery manufacturer’s recommendations or your hospital policy 
for the disposal of used batteries. 
8.4.2 Taking a Temperature with the TemporalScanner™ 
• To avoid cross-contamination, disinfect the probe head or install a cap onto 
the probe head before taking measurement on a different patient.
8.4.2.1 Understanding the Measurement sites
Recommended measurement sites are: temperature at the temporal artery area or 
temperature behind the ear.
Alternate sites when temporal artery or behind ear are unavailable: 
■ Femoral artery: slowly slide the probe across groin. 
■ Lateral thoracic artery: slowly scan side-to-side in the area, midway between the 
axilla and the nipple.
8.4.2.2 Taking a Temperature on an Infant
To take a temperature on an infant, follow this procedure:
1. Place probe flush on center of forehead and depress button. Keeping button 
depressed, slowly slide probe mid-line across forehead to the hair line. 
2. Release button remove from head and read measurement. 
  Temporal Artery Area        Behind the Ear
8 - 8 VS 8/VS 8A Vital Signs Monitor Operator’s Manual
• The preferred site is the temporal artery area. Unless visibly diaphoretic, one 
measurement here is typically all that is required.
• If the temporal artery is covered, then the area behind the ear, if exposed, can 
be an alternate site.
• Measure straight across the forehead and not down side of face.
• Brush the hair aside if covering the area to be measured. Measurement site 
must be exposed.
8.4.2.3 Taking a Temperature on an Adult
To take a temperature on an adult, follow this procedure:
1. Slide across forehead. Place probe flush on center of forehead and depress button. 
Keeping button depressed slowly slide probe mid-line across forehead to the hair 
line. 
2. Slide behind ear. Keeping button depressed, lift probe from forehead, touch 
behind ear halfway down the mastoid process and slide down to the soft 
depression behind the earlobe. 
3. Release button and read measurement. 
• Measure only the up-side on a patient in a lateral position. The down-side will 
be insulated preventing the heat from dissipating, resulting in falsely high 
readings.
• Think of a sweatband. Measure straight across the forehead and not down 
the side of the face. At mid-line, the temporal artery is about 2 mm below the 
surface, but can go deeply below the surface on the side of the face. 
• Measure exposed skin. Brush the hair and bangs aside if covering the area to 
be measured.
