What can cause inaccurate results when taking a tympanic temperature?

Other causes of false low readings include a dirty or cracked lens, improper technique, incorrect installation of the probe cover and short time intervals (less than 2-3 minutes) between consecutive temperature measurements.

How do you document tympanic temperature?

Aim the tip of the ear probe midway between the opposite eye and earlobe. This thermometer measures temperatures in less than 2 seconds. It is quick and painless and can be used to quickly get an accurate temperature if your child cannot hold still. When you hear a beep, remove the thermometer and read the temperature.

Do you add or subtract for tympanic temperature?

An ear (tympanic) temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

What can affect tympanic temperature readings?

Tympanic temperature readings may also be affected by the ambient temperature such as from incubators or may vary depending upon whether the ear used has been exposed to air or on a pillow or mattress.

How accurate is ear temp?

An ear (tympanic) temperature is 0.3°C (0.5°F) to 0.6°C (1°F) higher than an oral temperature. An armpit (axillary) temperature is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature. A forehead (temporal) scanner is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature.

When should you not take a tympanic temperature?

It concluded that tympanic temperature is one option for use with children, but suggested using rectal temperature for children younger than two, particularly when accuracy is vital. The tympanic temperature is not measured when a client has a suspected ear infection.

Why is my temp higher in one ear?

Taking temperature in the ear Always take the temperature in the same ear, as the reading in the right ear may differ from that in the left ear. This is a physiological difference which occurs naturally, and is important to keep this in mind when taking a reading.

Are ear temps accurate?

How accurate are ear thermometers? Tympanic thermometers, or digital ear thermometers, use an infrared sensor to measure the temperature inside the ear canal and can give results within seconds. If a person uses it correctly, the results will be accurate.

Why is tympanic temperature different in each ear?

Temperature can vary slightly from left to right ear because of the amounts of dirt or earwax present or due to individual variations. Please note the position of the probe tip during measurement can have an influence on the results.

Can an ear thermometer give a false high reading?

“In my clinical experience the ear thermometer often gives a false reading, especially if a child has a very bad ear infection,” Walker tells WebMD. “A lot of parents are uncomfortable taking rectal temperatures, but I still feel that they are the best way to get an accurate reading.”
