What is a Thermometer?
A thermometer is a body temperature sensing device that is easy to carry. How it is used depends on its type. The most commonly used type nowadays is the digital thermometer, which has a digital display showing the body temperature when measured.
Usage Instructions
A digital thermometer can be used in three different ways:
Oral:
This method is for adults and children aged 4 years and above who can hold the thermometer in their mouth. Follow these steps to measure temperature orally:
- Wash your hands with soap and water.
- Use a clean thermometer; wash it with cold water, disinfect it with alcohol, then rinse off the alcohol.
- Do not eat or drink anything for at least five minutes before measuring, as the temperature of food or drink may affect accuracy.
- Place the tip of the thermometer under the tongue.
- Hold the thermometer in place for about 40 seconds.
- The reading will continue to rise, and the symbol F (or C) will flash during measurement.
- The thermometer will beep when the final reading is done (after about 30 seconds).
- Rinse the thermometer with cold water, clean it with alcohol, then rinse again.
Rectal:
Mostly used for children up to 3 years old. Follow these steps to measure temperature rectally:
- Wash the rectal thermometer with soap and warm water. Do not use an oral thermometer.
- Apply a small amount of lubricant (Vaseline) on the thermometer sensor tip.
- Place your child’s belly on your lap or on a table, with one hand on their back; or place the child lying on their back with legs bent toward the chest, holding the back of the thighs with one hand.
- With your other hand, gently insert the thermometer into the anus until the tip is entirely inside the rectum. Do not force if resistance is felt.
- Hold the thermometer steady until you hear the beep (about 30 seconds).
- Remove gently, record the temperature and time.
- Clean the thermometer well with soap and water. It is best to disinfect again with alcohol and rinse.
Armpit:
Used for infants or adults who cannot safely measure orally. This method is less accurate than oral or rectal but can be used as a quick initial check. Follow these steps:
- Place the thermometer tip in your child’s dry armpit.
- Hold the thermometer in place by folding the child’s arm over their chest.
- The thermometer will beep when the reading is done (this method may take more than 30 seconds).
- Clean the thermometer with soap and water or alcohol, and rinse as a final step.
Frequently Asked Questions:
What should I look for when buying a thermometer?
Some thermometers are not recommended due to inaccuracy, such as plastic strip thermometers, which only measure skin temperature. Therefore, consult your doctor to determine the most suitable thermometer for your specific situation before making a purchase.They can advise on the best type for your family and recommend the most suitable
What Are the Signs That It's Time to Replace a Thermometer?
For digital thermometers: Test your device every six months or so (depending on usage) to ensure it's functioning correctly. Use the ice water method as follows:
- Insert the stem of the thermometer at least one inch deep into a cup of ice water, making sure the stem does not touch the glass. Wait for the thermometer to register a reading; this usually takes about a minute or less. The thermometer is considered accurate if it reads 32°F or 0°C.
Many digital thermometers come with a reset button. If you suspect the accuracy is off, recalibrate the thermometer using this button.
