- Tympanic Temperature The normal tympanic temperature is usually 0.3–0.6°C higher than an oral temperature (OER #1). It is accurate because the tympanic membrane shares the same vascular artery that perfuses the hypothalamus (OER #1).

What is a normal tympanic temperature?
Does tympanic membrane temperature reflect core temperature?
Does tympanic site affect body temperature?
Ear thermometers measure temperature from the tympanic membrane using infrared sensors and also aim to measure core body temperature, since the blood supply of this membrane is directly shared with the brain.
The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal temperature).
Sep 14, 2020 · Methods for measuring body temperature. Methods for measuring body temperature include: Tympanic thermometer – commonly used in clinical practice (Fig 1); Single-use chemical dot thermometer – commonly used with infants and small children; Rectal thermometer – frequently used when hypothermia is suspected;
Apr 9, 2019 · The calculated ranges (mean ± 2 standard deviations) were 36.32–37.76 (rectal), 35.76–37.52 (tympanic), 35.61–37.61 (urine), 35.73–37.41 (oral), and 35.01–36.93 (axillary). Older adults (age ≥60) had lower temperature than younger adults (age <60) by 0.23°C, on average. There was only insignificant gender difference.

Tympanic Temperature. The normal tympanic temperature is usually 0.3–0.6°C higher than an oral temperature (OER #1). It is accurate because the tympanic membrane shares the same vascular artery that perfuses the hypothalamus (OER #1). A tympanic thermometer is shown in Figure 2.4.
Upon arrival at the hospital, the tympanic temperature in the treatment group was significantly lower compared to the temperature in the control group, despite similar baseline temperatures (34.2 ± 1.5°C vs. 35.5 ± 0.9°C, p < 0.001), resulting in an average temperature drop of 1.3°C in 26 minutes.
Tympanometry is an acoustic evaluation of the condition of the middle ear eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal. Tympanometry is an objective test of middle-ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear. It is not ...
