Types of thermometers and its uses Mercury glass thermometers, although difficult to read, have been used for years to measure temperatures in the rectum, mouth or under the arm (but not the ear). They are no longer recommended because they can break easily and release toxic mercury. Electronic digital thermometers offer a number of advantages over glass thermometers. They get temperature readings faster and their digital display is easy to read. There is also no risk of injury from broken glass or mercury. Infrared thermometers measure the heat generated by surfaces and cavities. The main advantage of this type of thermometer is its speed - it only takes a few seconds to get a temperature reading. Infrared ear thermometers measure the heat generated by the eardrum and surrounding tissue. They give an accurate temperature on an easy-to-read digital display in seconds. Infrared forehead thermometers use the forehead to take a temperature gently. Front thermometers measure the infrared energy emitted by the skin over the area of the eyebrows and surrounding tissue. This energy is collected through the lens and converted into a temperature value. The accuracy of the thermometer depends on the type of technology used. Front thermometers can measure temperature by touching the forehead or from a distance. How to take the temperature? Temperatures are most often taken in the ear, mouth, bottom, under the armor on the forehead. Each method is considered to be correct when done correctly. Temperature readings may differ slightly depending on the method, so be sure to use the same method for consistency. Hear Ear measurements are gentle, easy and quick, and are therefore preferred by many parents. However, the temperature often varies between readings, which leads to the misconception that the ear thermometers are inaccurate. To minimize this effect, it is very important to use the right ear thermometer. Look for one with a small preheated tip and positioning aid to ensure accurate readings every time. As with any thermometer, make sure your child is still before taking a reading. Follow the manufacturer's instructions when using the ear thermometer. Reading the ears takes only a few seconds.
When taking the temperature with an ear thermometer, pay attention to the following points: Always take the temperature in the same ear, as the reading in the right ear can naturally differ from that in the left ear. External factors can influence the temperature of the ear, especially when an individual has: ● Lying on one ear or the other ● Had their ears covered ● Been exposed to very hot or very cold temperatures, or ● I recently swam or took a bath. In these cases, remove these external factors and wait 30 minutes before taking a temperature. ● If prescription ear drops or other ear medications have been placed in the ear canal, use the other ear to measure the temperature. ●
For accurate readings, the ear should be free of obstructions or excess of earwax.
Ear thermometers should not be used if the person has an external ear infection (otitis externa), as this could cause uncomfortable pain.
Never take a temperature in an ear that contains blood or drainage.
Forehead Using the forehead to take a temperature is a gentle way to monitor fever. Front thermometers measure the infrared energy emitted by the skin over the area of the eyebrows and surrounding tissue. This energy is collected through the lens and converted into a temperature value. ●
There are different types of forehead thermometers available on the market - it is important to take the temperature exactly as instructed in the instruction manual to ensure accurate readings.
Before taking a measurement, remove dirt or hair from the forehead area Position the therm
Armpits It is a safe and simple method for children of all ages. Here's how it's done: Make sure your child's clothes are not between the thermometer and the skin. Tuck the tip of the top thermometer into the armpit and hold it in place by lowering your child's arm and keeping it tight against their chest long enough to get the temperature reading. Oral Taking an oral temperature is generally recommended for children who can already easily hold the thermometer in their mouth. Here's how it's done: ●
Make sure your child hasn't had a hot or cold drink in the past 30 minutes and remains seated throughout the process.
Gently place the tip of the thermometer under one side of your child's tongue toward the back of the mouth.
Have your child hold the thermometer firmly in place with their lips and hands. If you use a digital thermometer, which is stronger than glass, your child can bite to hold the thermometer in place. You may need to help the first few times by holding it firmly.
The tip of the thermometer should not be exposed to the airflow during respiration as evaporation cools the sensor. Ask your child to breathe through the nose.
Rectal Taking a baby's rectal temperature is not difficult and should not be uncomfortable for your baby or for yourself. There are thermometers specially designed for rectal measurements that make it quick and easy. Here's how it's done: ● ●
Place your baby on his stomach or on his back on a flat, comfortable and firm surface, on your lap, on a changing table, on a sofa or even on the floor. If on your back, hold your legs as you would to change your diaper. If on the belly, place it so that its bottom comes out a little by folding its knees under or leaving its legs draped over your knees.
Dab a little lubricating jelly on the short, round tip of the thermometer.
Carefully insert the tip of the thermometer into the rectum (anus) until the metal tip is no longer visible (about a centimeter).
