NOTES ON TEMPERATURE
Why Measure in the Ear?
Clinical studies have shown that the ear is an excellent site for taking body temperature because the temperature taken in the ear reflects 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 in the tympanic membrane than in other places, such as rectum, mouth or under the arm.
Advantages of taking temperature in the ear versus traditional sites:
•Axillary temperature readings only reflect skin temperature, which may not indicate the internal body temperature.
•Rectal temperature often lag significantly behind internal body temperature changes, especially at times of rapidly changing temperatures.
•Oral temperature is often influenced by eating, drinking, breathing through the mouth, or the inability of the person to close his/her mouth completely.
Normal body temperature
Normal temperature refers to the body temperature of a healthy person. It differs among individuals and is affected by environmen- tal conditions such as time of day, atmospheric temperature, activity before measurement, site of measurement e.g. ear, mouth, or armpit. We recommend that you determine your normal body temperature by measuring several times under the same conditions.
How Does the Ear Thermometer Work?
The Ear Thermometer measures the infra heat generated by the eardrum and surrounding tissues. Clinical research has shown that the ear is an ideal site for taking body temperature since the eardrum shares blood vessels with the hypothalamus; the part of the brain that controls body temperature. To help ensure accuracy, the
Ear Thermometer takes 6 measurements within one second and displays the average temperature.
