Why the Temporal Artery?

Professional Technology for Parents

...patented Arterial Heat Balance
provides the breakthrough

- Gentle stroke of forehead captures naturally emitted heat from skin over temporal artery.
- Red LED lights and soft beep indicate correct scan
- Takes 1,000 readings per second, selecting the most accurate
- Arterial Heat Balance computes the correct temperature

The temporal artery is special - the only exposed artery on the skin surface which maintains constant blood flow - necessary for accurate temperature noninvasively at the skin. No other skin area has this property, and no other skin area can give accurate temperatures.

The temporal artery can actually be seen with a high-resolution infrared camera. Note that its location is different for each person, which is why you need to scan laterally to be sure you read it correctly. As the TemporalScanner scans across the artery, the very fast (1000 readings per second) sensing system selects the one peak value, which occurs precisely as the sensor is crossing the artery, and is the most accurate of all. Then the patented Arterial Heat Balance system computes the correct temperature by mathematically replacing the temperature that the blood lost in its short journey from the heart to the forehead.

The temperature that you read is called "arterial temperature" and is the most accurate of all temperatures, since it comes from the heart. It will usually be close to rectal temperature, but might be quite different under some conditions, particularly if your child has taken Tylenol, Advil, or other antipyretic, since your TemporalScanner will indicate reduced fever much faster than rectal. Also, when your child develops a fever, the TemporalScanner will indicate it much faster than rectal. As proven in a Harvard Medical School study on infants, your TemporalScanner is more accurate than an ear thermometer; and as provien in multiple hospital studies, has accuracy comparable to a rectal thermometer.
