Depending on the needs of the family, you can choose whether your new thermometer should be cheaper or more technological. The accuracy of the detection changes according to the patient’s ability to sit still or the device to offer more excellent stability during the measurement.

So the age of the patient and the frequency with which it is necessary to use it are fundamental when deciding how to choose a good thermometer.

Buyer Guide to Choose Digital Thermometers

Digital Thermometers with Bulb

After the ban on dangerous mercury, new devices for measuring fever were introduced, both in the hospital and at home. The liquid metal has not been completely abandoned and today the thermometers which in the bulb contain an alloy of different metals that react by expanding thanks to heat are still available and reliable.

This solution is not without flaws, however. Unlike mercury, when against cools down it is more difficult to reset to zero for reuse. Digital devices also appear in another fundamental aspect: the speed of detecting the temperature.

In a matter of seconds, the sensor in the bulb of the digital thermometer processes information on the temperature variation between the environment and the body temperature.

The result is shown on display. Here you can count on different variants and proposals that simplify the use of the thermometer. The screen can be simple, backlit, or change color depending on the temperature found. In this way, it is more intuitive to read the temperature.

Infrared Thermometers with Or without Contact

The opinions on these thermometers are very conflicting. They require particular attention when correctly positioning the sensor so that it detects the correct temperature. An error of thousandths of a millimeter implies a drastic difference between the real value and the detected one.

The operation at the base of the infrared thermometer is quite simple. The device can detect the change in temperature emitted by the body in areas where blood circulation is more superficial, just like in the center of the forehead or the eardrum.

The downside of these devices is that they must be positioned exceptionally accurately and used with high precision. It does not matter that the method works in contact, as in the case of the ear cable, or not in touch as to when measuring the temperature of the forehead.

What matters is to faithfully follow the manufacturer’s instructions and position the device in the exact spot. The goal is to limit as much as possible to detect the environmental temperature that alters the result.

There is also another problem that many detect and that generates skepticism, the substantial changes in temperature between one socket and another or the variations of a few tenths from one minute to the next.

Our body does not always have a constant temperature, and from one armpit to another, the variation can be remarkable. In the same way, it also varies from instant to instant as the body settles, raising its heat.

The Importance of Device Memory

When it comes to defining, which is the most suitable device for your family, it is good to evaluate that frequent and intense febrile episodes mark most of the very early childhood.

The child’s immune system reacts to attack by pathogens by raising body temperature. This phenomenon favors the action of the body’s defense mechanisms to bring the organism back to its healthy and disease-free state.

Most of the time, this simple self-defense system will eradicate the attack of viruses and the task of those who take care of children will only be to ensure that the temperature does not exceed certain limits.

A thermometer that helps keep track of the fever cycle, the highest peaks, or its persistence, also helps to keep under control the most suitable therapy to be administered as needed.

How to Use a Digital Thermometer?

There are a few precautions to follow when using a thermometer to measure fever, no matter if it is a digital or glass model. What matters is to respect the guidelines to have a reliable result and to intervene with the right therapy if necessary.

Personal hygiene and patient constitution are elements that should not be underestimated to make everything perfect.

What to Watch out For Before Measuring Your Fever

Some elements can alter the measurement apart from the operator’s inexperience. In the case of axillary measurement, it is good that the skin is well cleansed and dry.

Even when using the infrared sensor, it is good that there are no creams on the skin that can limit the detection capacity. Other obstructions should also be avoided, such as if infections are going on in the ear canal.

To detect otitis in the newborn, a simple maneuver can be performed. Just wait for a moment to calm the baby and check that the baby has no pain in the ears—just a light pressure of the fingers on the cartilaginous part that covers the ear canal.

Other precautions to follow when measuring oral temperature concern the intake of hot or cold drinks up to 15 minutes before the measurement. Stool deposits in the rectal ampoule can also alter the detection result.

Precautions to Be Followed to Avoid Accidents

There are some risks associated with detecting the temperature on which emergency room operators warn. The most striking is the possibility that the infant or child may get hurt while measuring rectal temperature due to a sudden movement.

Even unconscious patients or those with limited motor or mental skills are weak subjects who deserve the utmost attention when it comes to choosing how to measure fever.

The general recommendations regarding the choice of the rectal ampoule are to insert the bulb for half a centimeter in infants under four weeks and up to 2 cm for older children who, however, should never be in a supine position during the measurement. Given the invasiveness of the method, it is good not to resort to this solution more frequently.

With Preheated Tip

Sometimes the same manufacturer offers the possibility to slightly pre-heat the sensor tip to prevent contact with the cold object from suspecting the child.

Already dazed by the fever and the malaise it brings, it is normal for the little patient to be more intolerant and cannot stand contact with the cold surface directly on very hot skin.

For this reason, it is possible to choose to buy devices that limit the temperature change. At the same time, it is not advisable to manually heat the bulb because its measuring capacity could be altered.

Frequently Asked Questions

How Does Digital Thermometer Works?

A bulb contains a sensor that detects the temperature and processes it. It is used directly in contact with the skin or in the cavity, then it is placed in the armpit, in the groin, or the rectum or the mouth. It is essential to keep in mind that not all thermometers are already calibrated to discount the heat difference of the cavities.

Correct Functioning of The Digital Thermometer Depend On?

Most often, the error depends on the wrong positioning of the thermometer. Even the digital model with a contact bulb can report data distorted by incorrect use. If it does not adhere well to the skin, the sensor also detects the ambient temperature by altering the real measurement. For this, it is essential to make the sensor adhere well and allow it to identify the temperature from a single source.

How Do You Use the Digital Thermometer?

The thermometer, no matter if the bulb or infrared one, must be located in the same room where the measurement has been made for at least half an hour. This detail is essential to be sure that the device can accurately detect the difference between the ambient temperature and that of the body.

It is essential to use the thermometer precisely when it indicates that it is ready for use. Otherwise, it may start measuring the surrounding temperature and distort the result.

What Time Does a Thermometer Take to Give the Right Result?

We never talk about minutes, but about seconds and the duration of the detection varies from model to model. Some require that multiple measurements are taken at a time, and others can make an effective estimate even with a single exposure to the source to be measured.

Is Digital Thermometer Reliable?

If used well, it is exact and quick. What matters is being able to become familiar with the device and use it correctly following the specific indications.

Where Do You Put the Digital Thermometer?

If equipped with a bulb, it can be used indifferently where it is most comfortable depending on the age and physical characteristics of the patient. If it works with infrared rays, then it is necessary to position it exactly where indicated in the instructions.

When Does the Digital Thermometer Make a Sound?

Some devices inform of the detection with an acoustic signal. Others modulate and differentiate them according to the detected temperature.
