On average, a child's temperature is higher than that of an adult, therefore, if it is slightly elevated, this is not a reason for panic. But you need to know the baby's current body temperature, because it can be one of the main signs of a number of problems and pathologies. And if everything is simple with an electronic thermometer, because with the help of a sound signal it will indicate when it is necessary to stop measurements, then with a mercury one it is not entirely clear how many minutes to hold it to achieve the required accuracy. Let's try to figure it out.
How to measure the temperature correctly?
To measure the temperature of the child, you need to shake the mercury thermometer well (but gently), and then place it in the armpit. There is alternative options placement, for example, rectal, but usually the device is placed in the armpit. It is important to make sure that no sweat beads get on it, because they have a temperature that is slightly higher than the average temperature of any body.
As for how long it takes to measure the temperature with a mercury thermometer, placing it under the arm of the child, there is no difference with the duration of the measurement in adults. It takes 5 to 10 minutes. If you want to be sure of the result exactly, then soak it for 10 minutes. You don't need to hold it anymore. If it seems to you that the readings of the thermometer are not very convincing, try to repeat the measurement after a while.
- If the child is asleep, and you still need to measure the temperature, you first need to warm the thermometer a little in your hands. After that, you can take measurements, they will be more accurate than if you just put a thermometer.
- If the child is awake, he needs to remain as still as possible so as not to confuse the readings. Also, you cannot talk a lot, eat and so on. The more neutral he sits or lies, the better.
- When a child is at a very young age, when he is a newborn, it is worth giving preference to the rectal method of measurement. But in this case, it is simply dangerous to use a mercury thermometer, it is worth giving preference to an electronic one.
- In general, follow the progress of the measurement. A child can break a mercury thermometer - and this will be dangerous not only for his health, but also for his life, not to mention the fact that he can be injured by glass. In modern thermometers, mercury is often replaced by other similar liquid materials but, although they are less dangerous, they are also of little benefit.
- If finances allow, then there is another option - an infrared thermometer. It takes very little time to apply it - about five seconds. It is simply brought to the children's foreheads - and in a matter of moments the results are ready. If your baby is often sick, it may make sense to invest in such a device.
Summing up
The duration of the temperature measurement, how long it takes to carry it out, often causes certain difficulties. Remember that if you forget exactly how much to measure, there is nothing wrong with slightly exceeding the duration. After all, the child's body temperature during this time will not rise. But if you just don’t want to hesitate and want you not to have to think about the duration of measurements, so that you can concentrate on the health of the child, then just get a good electronic thermometer that will “tell” you when you need to take it out.
If you suspect the development of the disease, a thermometer is used for primary diagnosis. This device measures body temperature, and by its indicators it is easy to understand whether a person is sick or not. But many people are not sure how long it takes to measure the temperature with a mercury thermometer for a child and an adult. Someone out of habit holds it for three minutes, and someone - ten. How will be correct? "Popular about health" will help you figure it out and tell you about three ways to measure temperature.
Temperature control methods
There are three ways to measure temperature, consider them:
1. Axillary, when the thermometer is placed under the armpit.
2. Oral - under the tongue.
3. Rectal - in the rectum.
In all these cases, the use of a mercury thermometer is allowed, but it is not always justified. For example, to determine temperature values in a small child, you should not use the oral method if the parents have only mercury thermometer... Chances are high that the baby will break the glass and get mercury into the mouth. For the oral method, in this case, it is better to use electronic thermometers.
Oral method - rules for measuring temperature
When applying this method, you need to know how to properly position the thermometer in your mouth. To begin with, the device is disinfected with alcohol, after which the tip containing mercury is inserted under the tongue, the lips are closed. Breathing is done through the nose. Be careful not to damage the bulb of the thermometer with your teeth.
Rectal method
The rectal method involves the introduction of a thermometer into the rectum. Before starting the procedure, the tip of the device should also be disinfected, then lubricated with cream or petroleum jelly. The patient is laid on his side, the legs are bent at the knees. The tip is gently inserted into the rectum 4 cm for an adult, 2 cm for a child.
Axillary method
This method involves holding the thermometer near the lymph nodes - in the armpit or under the knee. It is used the most and is considered to be less safe. To use it, you need to make sure that the skin is dry under the armpit, firmly press the tip of the device and hold it.
It is possible to measure t a child with a mercury thermometer only in the presence of an adult and under his control. It is difficult to keep a small child in place for several minutes, so you should wait until the baby falls asleep or take the baby in your arms and press your hand tightly to the body, fixing the thermometer. Before the procedure, it is advisable to warm the thermometer in your hands for a few seconds, so as not to frighten the baby by touching the cold tip to the body.
How much to measure temperature with a mercury thermometer for an adult and a child?
How much time a child or an adult will need to determine the temperature depends on the chosen method of measuring it:
Oral - 4-5 minutes.
Rectal - 4-5 minutes.
Axillary - 7 minutes.
It will take an adult and a child the same time. The procedure does not depend on the patient's age. It is only important to understand that the temperature values in different parts bodies are different. This is exactly what will be discussed later.
What are the standards for temperature readings in the mouth, rectum and armpit?
Everyone knows that t is considered normal - 36.6 degrees when measured in the armpit. But this indicator or norm is conditional, since for many people it can fluctuate to a lesser or big side... By choosing other measurement methods, you will get completely different values. For instance:
When measuring t in the mouth, the norm is 37.3-37.5 degrees.
The norm for the rectal measurement method is 37.5-37.7 degrees.
The thing is that the mucous membranes are always much warmer than the skin, because the vessels are located closer there. For the same reason, rectal and oral methods are considered more accurate than axillary.
The accuracy of the readings depends on many factors. For example, it is important to measure t with a thermometer only at rest. Children are very mobile, when they run and jump, the blood heats up, because of which the indicators may be incorrect. Before carrying out the procedure, it is advisable to follow the following rules:
1. Do not take a warm bath.
2. Do not consume hot food or drinks.
3. Don't run.
If you are in doubt about the performance of the device, wait a few minutes, then repeat the entire procedure. It is worth noting that old mercury thermometers, which have served for many years, heat up more slowly, so to be sure, wait a couple of extra minutes or use another device. As you guessed, this is why many people know about the time of measuring the temperature under the arm for 10 minutes.
Advantages and disadvantages of a mercury thermometer
A mercury thermometer is considered more reliable and accurate, capable of serving for many years; its readings do not depend on the state of charge of the battery inside. These are the main benefits. There are also disadvantages:
The device is fragile and must be handled with care.
The inside of the flask contains mercury, a highly toxic substance.
The duration of the procedure is longer in comparison with the electronic analogue.
Temperature data is very important for diagnosing diseases and determining the well-being of adults and children. To make the data as accurate as possible, adhere to the rules described above.
What is a thermometer? A familiar medical device is found in almost every apartment. Why it is not difficult to find it in a family with any income (moreover, often in several copies), there is no need to explain, since it is not possible to measure the temperature without a thermometer.
You can touch the patient's forehead with your lips or measure a person's pulse, however, these actions will only help to understand that the temperature is too high, but there is no need to hope for accurate results. Any working thermometer is an important and necessary subject. This fact does not cause controversy. Disputes over how long a thermometer should be kept is ongoing. Let's try to figure out the optimal time required to determine body temperature.
- Types of thermometers
- Which thermometer should you choose?
Types of thermometers
- Mercury is an inexpensive and most accurate instrument. Its disadvantage is its fragility and for a long time measurements, but there are no competitors in the accuracy of readings. How much to keep a mercury thermometer depends on the method of measuring the temperature:
- in the rectum or mouth - 5 minutes;
- in the armpit - 10 minutes.
History reference. The prototype of the liquid thermometer was the thermoscope invented by Galileo in 1603. After 23 years, Santorio improved this device and measured the temperature of the human body for the first time. The famous Fahrenheit was filled with mercury in 1714. At first he suggested using physical properties alcohol. But I noticed that under the influence of heat, mercury expands more evenly.
- Electronic - it is more expensive and less accurate than a mercury device, but at the same time it gives a result much faster. Each such gadget emits a sound signal at the end of the temperature measurement, the whole process takes from 2 to 5 minutes.
It is interesting. Thermometer-tattoo - a kind of electronic thermometer for permanent wearing on the skin. The personal device was developed by a group of scientists from America, China and Singapore. Outwardly, it is a thin film with golden sensors, reminiscent of a tattoo with a barcode. It is attached to the skin with inside wrists with special glue. Measures body temperature throughout the day. True, it is not yet particularly accurate.
- Infrared (non-contact) - it is enough to bring it to the person's forehead or insert it into the ear, the exact temperature data will be known in 5 seconds. The disadvantage of this type of device is the overpriced. Plus - absolute safety and high measurement speed.
New developments. Today, in pharmacies, you can often find thermometers in the form of a pacifier. Unfortunately for growers and parents, not all babies like these options. Some spit them out, others start gnawing ... Korean designers tried to fix the situation. They suggested measuring the temperature with ... lollipop. The most real and quite edible. The thermometer is a stick, at the measuring end of which there is a replaceable sweetness. While the baby is eating, his temperature is measured. If the idea is implemented and goes into mass production, then replaceable sweets will be sold in pharmacies.
- Disposable (travel) - is a strip that should be applied to the forehead or placed under the tongue. Colored divisions will help determine body temperature. It takes a minute to hold such a device. Similar device will be convenient while traveling, but you cannot count on an accurate result with it.
How long to hold the thermometer under the arm
Mercury and electronic devices are most in demand due to their affordable cost and ease of use. With their help, the body temperature in the armpit is usually determined, since this method brings a minimum of inconvenience, especially when you need to understand whether a child has a fever or not.
The answer to the question of how long to keep the thermometer under the arm is as follows:
- 2 to 5 minutes when using an electronic device;
- from 8 to 10 minutes when using a mercury device.
Which thermometer should you choose?
You need to choose a medical gadget based on who needs to measure the temperature and in what conditions.
For babies and children younger age An infrared thermometer is fine, as it gives an accurate temperature in a matter of seconds. It is very convenient that the child does not need to undress and it is enough to free the forehead.
For adults, it is best to use a mercury meter as it provides the most accurate reading. You will have to wait a while to display adequate body temperature information.
For travel and business trips, disposable strips are perfect, as you don't have to worry about them breaking or breaking.

The duration of the procedure is longer in comparison with the electronic analogue.
Temperature data is very important for diagnosing diseases and determining the well-being of adults and children. To make the data as accurate as possible, adhere to the rules described above.
Measurement methods
Today, the most popular method is measuring the temperature in the armpit. However, this is far from the only way... Measurements can be carried out in the following areas:
- in the rectum;
- behind the ear (using an infrared thermometer);
- v oral cavity;
- under the knee.
How long does it take to measure? It depends on two factors: on the above-mentioned measurement methods and on the type of thermometer.
Mercury thermometer
A mercury thermometer is an inexpensive and accurate instrument. Among the shortcomings - fragility and a significant amount of time required for measurement, but in terms of accuracy of readings, it is out of competition.
How many minutes do you need to hold a mercury thermometer:
- rectally or in the mouth - 5 minutes;
- under the arm - 10 minutes;
- under the knee - 10 minutes.
Such a device is much more expensive, and it is not as accurate as a mercury thermometer, but the procedure for measuring the temperature is much shorter.
The time required for the measurement does not even need to be detected, because the device at the end of the process will emit a sound signal, notifying that the measurement is complete. This usually happens after 1–3 minutes, regardless of the measurement method.
Modern manufacturers offer a wide range of electronic nipple thermometers for babies. With such a gadget, the procedure will not cause any concern for the crumbs, because he will perceive the device as an ordinary nipple.
Infrared thermometer
It is a non-contact device that just needs to be brought to the area behind the ear or to the forehead, and it will give accurate readings. The cost of such a gadget is quite high, but its usability is difficult to dispute.
First of all, comfort is associated with the duration of the procedure: measuring the temperature with an infrared thermometer will take no more than 5 seconds, and besides, it is absolutely safe.
Disposable thermometer
A travel thermometer is a strip that is held on your forehead or placed under your tongue. The body temperature is determined after a minute using the colored divisions on the strip.
You should not expect an accurate result from such a device, however, it is ideal for determining indicators on the road.
To obtain reliable indicators, it is not enough to know how much you need to hold the thermometer, you also need to carry out the measurement procedure correctly. So, if you measure body temperature with a mercury or electronic thermometer, then adhere to the following rules:
- When measuring temperature, make sure that the skin is not wet. It is known that a person sweating will have an overestimated value.
- When measuring under the arm, you need to press your hand to your body and hold the inserted thermometer tightly. Then the question will not arise: "Why is the temperature on the thermometer minimal, because I have been holding it for a long time?"
- If the measurement is taken under the knee, then 10 minutes need to hold the device with a bent leg. In this case, you need to lie down.
- Measuring temperature small child, you need to first warm the thermometer in your hands so as not to frighten the baby with a touch of a cold object. It is most convenient to take measurements under the arm while the baby is sleeping.
- Children can use the thermometer rectally. An electronic device is better suited for this. Firstly, it is not so traumatic, and secondly, the procedure time with it is shorter. However, it should be borne in mind that the temperature in the rectum is slightly higher than, for example, under the arm.
- It must be remembered that older mercury thermometers react more slowly to changes in readings, so they take longer to measure.
- Shake the mercury thermometer with sharp, short strokes, holding it between the index and thumbs... In this case, the column should drop to a mark of approximately 35.5 degrees. It is best to do this over a soft surface to avoid damage to the thermometer in the event of a fall.
- After the procedure, rinse the device with cool water.
- Use the same thermometer to re-measure.
Now you know how to correctly measure the temperature, how long to hold the device under the arm, under the knee, etc. This knowledge is necessary for every adult who cares about own health and about the health of their children.
The effectiveness and correctness of therapy depends on how responsibly you approach the issue of temperature measurement. We hope that our advice will help you get the right readings and start the treatment you need right away.
How long does it take to hold a thermometer
It would seem a simple question, but not - the measurement time depends both on the thermometer itself (mercury-electronic-infrared-liquid crystal) and on the measurement zone (under the arm - rectally - in the oral cavity - in the area of the tympanic membrane - near the temporal artery )
Relatively accurately, we will answer the question of how many minutes to keep a mercury thermometer - 10 minutes.
Traditionally in every home or medical institution there is a mercury thermometer. It is very accurate and easy to use. But it contains very Hazardous Material- Mercury. Made of glass, it is fragile and, if used carelessly, can shatter, splashing out many tiny balls of mercury, which is very difficult to collect.
It was the content of mercury in the thermometer and the possibility of pouring out mercury that led to the introduction of a ban on the use of these thermometers in some countries of Western Europe.
21st century offers new safe methods temperature measurements with electronic, infrared and liquid crystal thermometers.
And here the questions began.
How many minutes to keep the electronic thermometer? How many minutes to hold an electronic thermometer with a flexible tip? How long does it take to keep an infrared thermometer?
How long to hold a thermometer
So, we counted 4 types of thermometers: mercury, electronic, infrared, liquid crystal.
The principle of operation of a mercury thermometer is clear to everyone - when heated, mercury expands, moves along a calibrated channel and stops at the point of equality with body temperature. How many minutes it takes to hold a mercury thermometer was explained to us by my grandmother - about 10 minutes.
The principle of operation of a liquid crystal plate is also simple - at certain temperatures, various parts of the plate are illuminated, on which the degrees themselves are applied. Such a thermometer will show the temperature with an accuracy of half a degree in 20-30 seconds. Fast, painless and absolutely safe!
The principle of operation of an infrared thermometer is quite clear - contact and non-contact. He uses optics to study the surface temperature of an object. The optics of the device picks up thermal energy and focuses it on the detector. The electronics of the device gives out the value of this energy and converts it into a digital value of the temperature on the screen of the device. By the way, the laser built into the device is used only for target designation. This thermometer works extremely fast. Few seconds. 4-5, and sometimes faster.
Principle of operation electronic thermometer is reduced to a simple chain: the resistor heats up, its resistance drops and the current increases.
The operating time of such a thermometer is quite long - up to 5 minutes, this is because the thermometer clearly reacts to minor temperature changes in the armpit and cannot "calm down" in any way.
In this sense thermometers with flexible tips for oral use (under the tongue) are more reliable.
IT'S IMPORTANT TO KNOW:
Temperatures vary by part of the body The temperature of different parts of the human body can
differ by 0.2 - 1 ° С In order to correctly assess the change in a person's temperature, it is necessary to know its personal norm.
To do this, it is enough to take a series of measurements of your own temperature at the same time during the period of subjective feeling of health.
Typically, a young child's body temperature is higher than that of an adult.
Therefore, it is very important to know the average normal temperature in a child.
Everyone has their own temperature norm
In the area of the temporal artery (on the forehead) 35.5 - 37.5
In the area of the tympanic membrane (auditory canal) 35.8 - 38.0
Rectally (in the rectum) 36.6 - 38.0
Orally (oral cavity) 35.5 - 37.5
Axillary (under the arm) 34.7 - 37.3
Range of normal values of temperature depending on the method of measurement
Rectal measurement is carried out only in cases where it is prescribed by a doctor, cannot take measurements orally or axillary. The thermometer probe must be positioned exactly
in the middle of the armpit.
For getting accurate result, the thermal sensor of an electronic thermometer should fit as tightly as possible to the skin under the arm. The hand must be firmly pressed against the body until the end of the measurement.
The thermometer must be placed on the side under the tongue.
Throughout the measurement procedure, you must keep your mouth closed.
This method is strictly prohibited for measuring with mercury thermometers!
Measurement from 10 seconds to several minutes.
The forehead is one of the best places to measure temperature due to the presence of an artery nearby that carries blood from the heart to the brain. 
For an accurate measurement of body temperature on the forehead, it is enough to gently hold a forehead infrared thermometer at the temples, and after a few seconds the temperature will be determined. It is even easier to determine the temperature using a thermotest strip or a liquid crystal thermometer. You will receive the result in 15-20 seconds! In order not to damage the eardrum, ear thermometers are equipped with special soft tips - tips and are absolutely safe.
ATTENTION! In no case should the vikoristovuvatusovuyu passage to measure the temperature with conventional thermometers.
Measurements taken in the ear allow you to measure
the temperature of the "core" of the body, which is the temperature of the vital organs since the eardrum is supplied with blood by the same circulatory system as the brain. The center of temperature control is the hypothalamus. Therefore, changes in body temperature occur faster and more accurately in the ear than elsewhere.
To accurately measure body temperature in the ear canal
no effort is needed: pulling the earlobe up and
back, you need to straighten the ear canal so that the eardrum becomes visible. Then it is necessary to insert the thermometer probe into the ear. In the area of the temporal artery (on the forehead)
Temperature measurement with an infrared thermometer in the area of the tympanic membrane (ear canal)
Measurement in a few seconds.
If a person suspects that he is ill, and this is especially often the case in winter period, then the first means to confirm these guesses is the thermometer with which it is measured. If it is high, then you need to start immediate treatment so as not to get complications. But does everyone know how long to keep a thermometer?
Let's start with the fact that there are electronic ones. Both should be able to use correctly in order for the readings to be accurate. It is also very important that the temperature of children and adults is measured in different ways.
The most effective is a mercury device. At the same time, electronic is more secure. Exact time How long to hold a thermometer depends on what it is. So, mercury thermometer measure the temperature from three to ten minutes. For three minutes is enough to find out the exact reading. Now you know how long you need to hold a mercury thermometer and how much is an electronic one. There is no doubt that the second option will measure the temperature much faster. To reset the reading, after you have already measured the temperature with a mercury thermometer, be sure to shake the thermometer, otherwise next time these results can be overestimated. With the help of an electronic device, you can more accurately find out your temperature.
How to hold it correctly should be clamped under the arm. In this case, the skin should not be sweaty, otherwise the readings will be incorrect. The thing is that the temperature of the sweat produced is higher than that of the body itself, therefore, in the case of moisture under the arm, the measurement result will be clearly overestimated.
While you are waiting for the reading, you should keep your hand firmly pressed to your body. After a few minutes, you will see the correct readings on the thermometer. If you have an old mercury device, then you can slightly extend the measurement time, since being in operation for a long time, such thermometers react more slowly to changes in body temperature.
Now that you know how long to hold the thermometer, you can use another method to insert the thermometer under the knee. The leg must be bent so that the thermometer is firmly held for the right time. This method is best done while lying on your back or on your side.
Young children can have their temperature taken rectally by inserting a thermometer into their buttocks. Here it will be more convenient and safer to use electronic device, as it measures faster and cannot harm the child. Remember that the reading is always slightly higher than when measured under the arm or under the knee.
To the question of how much to hold a thermometer for a child, one can confidently answer: as much as an adult. If the baby is asleep, then you can put the thermometer under your arm, after warming it in your hands. This way you won't wake him up with a cold touch. Be very careful not to disturb the baby's sleep, otherwise the temperature is unlikely to be measured.
If you know how long you need to hold the thermometer, but as a result of measurements it seems to you that the readings are not correct enough, then repeat this procedure again. Measure the temperature again to be sure the results are accurate.
Regardless of whether you use mercury or you use to measure the temperature of a child, this must be done very carefully. This is especially true for a mercury device, because mercury is a very dangerous substance.
Lovers of skipping school know how to artificially raise the temperature. To do this, for example, they take out a lead from a simple pencil and simply eat it. Yes, the temperature does rise, but at the same time you run the risk of poisoning. Therefore, it is better not to resort to such methods.
