Ear Thermometer Advantages

Infrared Ear Thermometer measures core body temperature, which is the temperature of a body’s vital organs. (See Figure 1) Ear temperatures accurately reflect core body temperatures since eardrum is in the cranial cavity and is not affected by the environment. The eardrum shares blood supply with the hypothalamus (part of the brain.) Therefore, body temperature changes are reflected sooner in the ear than they are in other parts of the body.

Ear Thermometer Advantages

Clinical studies have shown that the ear is an excellent site for temperature measurement because temperatures taken in the ear , reflect the body s core temperature. Body temperature is regulated by the hypothalamus, which shares the same blood supply as the tympanic membrane. Changes in core body temperature are usually seen sooner at the tympanic membrane than at other sites, such as the rectum, mouth or under the arm.
Advantages of taking temperatures at the ear versus other sites:

•  Axillary temperature readings only reflect skin temperature which may not indicate the internal body temperature.
• Rectal temperatures often lag significantly behind internal body temperature changes, especially at times of rapidly changing temperatures.
• Oral temperatures are often influenced by eating, drinking, thermometer placement, breathing through the mouth, or the inability of the person to close their mouth completely.

Body Temperature

The temperature of a healthy person is affected by various factors: the person’s individual metabolism, their age(body temperature is higher in babies and toddlers and decreases with age. Greater temperature fluctuations occur faster and more often in children, e.g. due to growth spurts), their clothing, the ambient temperature, the time of day(body temperature is lower in the morning and increases throughout the day towards evening), the preceding physical and, to a lesser extent, mental activity.
It is suggested that users develop the habit of daily measurement, and use this product to establish a private normal temperature range for themselves and their families as a reference for measurement.

b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2,7 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for transmitters in these frequency ranges.
c Field strengths from fixed transmitters, such as base stations for radio(cellular/ cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.
d Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
