Proper use of a thermometer through your ears
A good clinical thermometer can accurately measure body temperature through the ear. However, you should take into account that a temperature measurement via the ear is always an indication. The thermometer must be used correctly to get a correct reading. Body temperature can be measured by the temperature of the eardrum. The temperature of the eardrum is reasonably equal to the body temperature. The difference is only 0,22 degrees. A good thermometer will correct this small difference. To accurately measure body temperature, the clinical thermometer near the ear must be pointed inwards. You need to make sure that the infrared sensor is correctly pointed into the ear canal. You put it in the ear and then point it slightly upwards. This directs the infrared sensor towards the eardrum. Sometimes you need to give a little space in the ear canal by lightly pulling on the earlobe. The ear canal then becomes larger, so that you simply aim at the eardrum. If you aim lower or higher, the reading will be lower than the actual temperature. This can easily make a difference of five degrees. If you are going to measure the temperature with a digital ear thermometer, it is best to measure several times. For example, two or three times. You then take the highest temperature value from the measurements. You don't have to worry about going too deep with the thermometer and damaging the ear. The sensor of the thermometer only enters a small distance. The sensor is covered with a lens filter. A lens filter ensures that the thermometer does not get dirty. From a hygienic point of view, it is recommended to replace the lens filter after each measurement. If you suffer from an ear infection or if you have a lot of earwax, the measurement may be less accurate. This makes the ear canal less accessible to the sensor. In these cases it may be advisable to measure the temperature through the mouth or rectum using a clinical thermometer.
