Temperature can be taken in the ear, mouth, bottom, under the arm or on the forehead. Each method is considered accurate when done correctly. Temperature readings can differ depending on the method, so be sure to use the same one for consistency. Two popular places to take a temperature reading are the ear and the forehead.
Taking temperature in the ear
Because ear measurements are so gentle, easy and fast, it is a popular site for taking measurements among parents.
Always take the temperature in the same ear, as the reading in the right ear may naturally differ from that in the left ear. This is a physiological difference that occurs naturally, and not due to the thermometer.
Consider external factors
Ear temperature can be affected by things other than true body temperature, for example when the person has been:
• Wearing something over their ears
• Lying on one ear or the other
• Exposed to very hot or very cold temperatures
• Recently swimming or bathing
In these cases, remove the external factors and wait 30 minutes prior to taking a temperature.
When not to use an ear thermometer
If prescription eardrops or other ear medications have been placed in the ear canal. (Use the other ear instead.)
If there is excess earwax. (For accurate readings, make sure the ear is as clear as possible.)
If the person has an outer ear infection (otitis externa). Using an ear thermometer could result in discomfort or pain.
If there is blood or drainage in the ear.
How to use a Braun Thermoscan® thermometer
If you are using a Braun ThermoScan® thermometer, here is how to correctly measure your child’s temperature with it:
1) To achieve accurate measurements, make sure a new, clean Hygiene Cap is in place before each measurement.
2) Place the ear probe snugly in ear canal and directly toward opposite temple.
3) Keep the thermometer steady in the ear canal
4) Take a measurement by pressing the “Measurement” button
5) Dispose of the used Hygiene Cap
Taking temperature using the forehead
Using the forehead to take temperature is a gentle way to monitor a fever.
Forehead thermometers measure the infrared energy emitted from the skin. This energy is collected through the lens and converted to a temperature value.
Always follow the manufacturer’s instructions to get the best results.
How to use the Braun No Touch + Touch thermometers
1) Before taking a measurement, remove dirt or hair from the forehead area
2) Remove protective cap
3) Press the ON/OFF button
4) If using touch method, position the thermometer in front of the forehead in the middle of the eyebrows touching the forehead.
5) If using no touch method, position up to two inches away if using NTF3000, one inch if using BNT400, each using the proximity sensor and aiming light. For patients measuring their own temperature, it is recommended to use the “touch” option instead of “no touch” as it is much more convenient.
6) Keep the patient’s head still during measurement. Do not move the thermometer during measurement
7) Press the Temperature button to take a measurement
Temperature taking hints
• Make sure you let your thermometer acclimatize to room temperature at least 10 minutes before you’re taking the measurement.
• The person being measured should be indoors for 30 minutes before taking a measurement.
• Before taking a measurement:
o Wipe away any sweat with a dry cloth.
o Ensure that the forehead is clean. If you clean forehead, wait 10 minutes before taking a measurement.
o Make sure to move hair away from forehead and wait 10 minutes before taking a measurement.
