Tonometer on hand to measure pressure. What a tonometer on the wrist is better: features and selection criteria

Hello, dear friends!

Today, as promised, we will talk about tonometers. I think, after a detailed conversation about hypertension, it is logical to talk about the meters.

Perhaps, for many of you, the choice of a tonometer does not represent special difficulties.

And wonderful!

Therefore, I am very glad if you also find something valuable in this article.

But I know that thousands of people who do not have any relation to pharmaceuticals are gaining daily in the search engine phrase "how to choose a tonometer?" And who knows, maybe they will score just on this blog.

Therefore, I want to give me the most detailed information about how to choose the right tonometer for myself and your loved ones so that then it was not painfully hurt for the money thrown on the wind.

What will this conversation be about?

First, we will analyze what is the tonometers, and how they work.

Secondly, they reflect on the eternal question of buyers "And what tonometer is better?"

Thirdly, we think about what questions you need to ask the buyer who wants to purchase a tonometer.

Fourth, remember how to measure blood pressure correctly.

Fifth, we will analyze the most frequent questions of buyers and will define how to answer them.

Well, ready?

Then let's start.

What are the tonometers?

Look at this scheme:

So all the tonometers are divided into mechanical, semi-automatic and automatic.

The latter are on the shoulder and on the wrist.

A long time ago there was another mercury tonometer, which was the most accurate because, as you know, blood pressure is measured in millimeters of a mercury pillar.

These are the most millimeters he showed.

Once we had such a house. After the first infarction, the doctors strictly-setting were punished regularly to measure the pressure, and the mother somewhere got the device with the beautiful name "mercury sphygmomanometer Riva-Roches" (this is the name of the Italian doctor who invented it).

When my sister and I studied at the Medical Institute, the very first thing we had learned to do from medical manipulations - to measure pressure, because We had a regular home practice.

But this apparatus was unsafe. I remember, we accidentally disgraced the glass column of the device, incorrectly closed it, and the mercury droplets broke out. Therefore, my mother had to get another.

Mechanical tonometers came to replace mercury.

First, they are more compact. Secondly, safe. And thirdly, the same accurate as their progenitor.

In a mechanical tonometer, everything has to do with the measuring: and heating the air into the cuff, and drop it, noting the digit on the pressure gauge scale, when the pulsation begins (this systolic pressure), and the digit when it stops (this is diastolic pressure).

The principle of the mechanical tonometer

When the air pressure in the cuff becomes higher than blood pressure in the vessels, the blood flow in the shoulder artery stops. We do not hear any tones in the stethoscope tube.

Then, when the air descends, the clearance of the arteries is opened, the blood flow is restored, and the tones of Korotkov appear in the tube.

After a few seconds, the air pressure in the cuff falls so much that the artery opens completely, and the noises disappear.

Korotkov Nikolai Sergeevich is a Russian surgeon, which at the beginning of the 20th century first invented an auscultative method for measuring blood pressure, that is, with a stethoscope listening. Previously, it was made palpatorially (with the help of fingers - how we tackle the pulse).

Semi-automatic tonometers

In these devices, pressure is the same as in mechanical, pumped with a pear. But then the tonometer is already doing everything: drops the air and gives out the result on the screen.

Automatic tonometers

Well, in these devices do not need to do anything. No, I lie. Need to.

Press the big button. And all!

The remaining operation of the tonometer machine will make a person: punishes the air into the cuff, will lower the result.

Principle of action of semi-automatic and automatic tonometers

In these devices, an oscillometric method of measuring pressure is used.

The oscillations (oscillations) of the arterial pressure in the artery of the hands, which occur when air blending cause air fluctuations in the cuff on the hand, which is registered with a special device sensor and then processed by the built-in microprocessor.

What tonometer is better?

What do you think Friends?

When I hear in the pharmacy that some visitor asks a mechanical tonometer, because he said so the attending physician, I really want to see him. Allegedly only such a tonometer is accurate, and all the electronics is lying.

A few years ago I was on learning at Omron, and of course, we also wondered this question. We conducted an experiment: the same colleague was measured and with the help of an automatic device and using mechanical. The result was, as it is called, tupping in a tip.

Why did the results coincided?

Because:

Measuring arterial pressure with a mechanical tonometer is a medical procedure !!!

On that study, I learned an amazing thing: it turns out that in Japan, he is taught medical pressure to measure blood pressure. Imagine? Half a year!

And we have every granny 70-80 years old believes that there is nothing complicated.

Whether my will, I would have let go of mechanical tonometers only after presenting a diploma about the end of the medical school.

And that's why.

One day, a study was conducted among ordinary people, never do the physicians who measured their pressure with a mechanical tonometer. It turned out that 75% such measyers incorrectly determined the tones of Korotkov.

And even well, if this tonometer measures the pressure of another person. But people manage to measure themselves! And one pumping of pear increases the pressure of 10-15 mm Hg Art.!

In addition, we will not forget that the elderly has vision problems, with hearing. I saw something, I did not hear it.

And it still happens that the pressure gauge lay on the table, and was not attached to the cuff, and this also distorted the results.

Or measuring too quickly blended air and did not catch the first and last digits.

Some people when measuring pressure are not focused on the tones, but on the oscillations of the arrow of the pressure gauge. But it's not right!

Among other things, when the filling of the pulse is weak, and it often happens in the elderly, there can be complete silence in the tube. And then the man is frightened, and his pressure is even more rising.

Thus, list ...

9 reasons why I do not advise you to acquire a mechanical tonometer by nonimiles:

1. Measure pressure with a mechanical tonometer must be a specially trained person.

2. 75% of the measuring incorrectly determine the pressure.

3. Hearing and viewing increases the likelihood of error.

4. The pressure measurement itself increases it by 10-15 mm Hg. Art.

5. Incorrect position of the pressure gauge increases the likelihood of error.

6. Excessive injection of air in the cuff and rapid blending affect the correctness of the result.

7. With a weak filling of the pulse of the tones in the tube is not heard.

8. Repeated air ventilation into the cuff during the measurement process to catch the first and last tones, distort the result.

9. Few people know that the mechanical tonometer must be able to calibrate annually (customized for standard) in the service center.

You say, well, and what, not to sell them, or what?

Of course selling: doctors and in the case when no arguments did not convince the buyer.

What about machine guns and semi-automatic?

Buyers are always interested in the question, how accurate electronic tonometers?

Their error is only 3-5 mm RT Art. This figure is not significantly significant.

They are designed specifically for home use People without medical education.

If we compare automata and semi-automatic machines, let's argue logically.

The semi-automatic pear is also pumped by independently, it means that it is again physical activity that can affect the measurement result.
If we talk about a very elderly person, then it is hard for him to work with a pear: the power of the muscles is not the same. Is it easier to purchase it really easy and convenient to use the device? I mean automatic.

As you understood, I am for automatic machines. I have long been using only automatic devices. And I have two of them: and and Omron. And both are already working 100 and 1 year, and I have no complaints to anyone or another.

The only thing that scares some buyers from buying a machine gun is the price (if you do not consider the opinions of their attending physician, what I have already said above).

But five (for Omron) and ten (for and) years warranty speak for themselves. And, as a rule, these devices serve much longer.

Share the price of the tonometer for the warranty period, and it will turn out that a month a person spends on behalf of the dear penny. Spend these calculations with the buyer.

About tonometers on the wrist

A two more words about the tonometers on the wrist.

On the same learning about which I said, we were very interested in the question about the accuracy of the tonometers on the wrist.

Omron specialists believe that crew tonometers are as accurate as shoulder, and can be recommended regardless of age.

And then, we then went on the principle of "trust, but check" and measured the pressure to the same person with shoulder and crew tonometers. The result was again the same.

But, nevertheless, after working in 9 years in pharmacies, I realized that the custodia devices better offer to people about 40 years. And that's why:

With age, the vessels wear out, and the wrist vessels are faster because they are thin. The elasticity of their walls falls. And for accurate measurement, their good condition is necessary. Shoulder artery is more enduring in this regard, which means it is better suited for trapping oscillations (oscillations).
The elderly person for life can "accumulate" various microtraums in the field of ray-taking joint (stretching, bruises, etc.). This is a contraindication to the use of crew appliances.
With aging, various joint deformations arise, "bones" appear, which leads to the wrong imposition of the appliance cuff.

Have you been waiting for now I will tell you about the notorious atherosclerosis? I will not say, as atherosclerosis affects large and medium arteries. Cardicate to those do not belong.

Now we will analyze what questions you need to ask the buyer when buying a tonometer.

Who takes? We ask to understand, the device is purchased for a man. If for a person of young and middle age - you can offer my shoulder, and curses. If for the elderly - only shoulder.
Are there any heartbeat interruptions (arrhythmias)? If "yes" or "do not know", then we offer only with the function of intelligent dimension. If not, any.
If you take not for yourself, ask a person's hand full? If a person makes it difficult to answer, we offer a tonometer with a universal cuff. If for yourself, we immediately pretend to the complex of a person, which cuff is needed here.
How many people will use a tonometer? If two, we offer with memory for two.
If you are relatively young man, ask where do you plan to use it? At home? On trips? For trips, the compact models of the type of crew or small semiautoms will be better.
Is it important to memorize the date and time of measurement? If yes, choose models with the date and measurement time.

I did not write about the "memory", since this function is in most modern tonometers.

These are basic questions.

You can download this algorithm by clicking on the picture:

What is the function of intelligent pressure measurement?

The function of intelligent pressure measurement is probably provided now in the tonometers of any brand.

It means that with each pressure measurement, the device itself determines the optimal level of air injection. It measures the pressure already in the process of injection of air, it analyzes in detail the pulse wave and in the case of arrhythmia chooses a fragment with the most stable ripple so that the measurement result was as accurate as possible.

How to measure pressure?

I tell how it should be ideally:

Below you see a very useful table. To download it in the form of a Vordovsky file, click on it.

I advise you to print it, and even better to illuminate the addiction, and show the buyer.

Very important!

When you measure the pressure to the buyer in the pharmacy, tell him that you are now only checking the work of the device and explain how to use it.

You do not measure pressure! Since very many factors affect the pressure numbers.

This most you warn objections:

- The device is lying.

- I have no such pressure.

- Why is such a high?

I believe that the measurement should be carried out on yourself, as many employees of pharmacies do, and on the buyer.

Firstly, due to the characteristics of the cardiovascular disease, the tonometer can constantly issue an error, and checking the operation of the device on the buyer, you will understand, this model suits him, or not.
Secondly, you will see if the cuff is not small.
When the pressure is measured by the buyer, he already mentally "affected" with him and represents how they will use it at home. Therefore, such a sale is easier.

Frequent buyers questions

1. What hand need to measure pressure?

First you need to determine if there is a difference between the pressure indicators on both hands. If it is not more than 10 mm Hg. Art., can be measured for any. Rightstim will be convenient to measure on the left hand, left-handers - on the right.

But at first you need to spend several measurements on both hands.

If the difference exceeds 10 mm Hg, it should be measured on hand with higher numbers.

2. Why is the pressure on both hands very different?

This is possible with serious vascular pathology: narrowing, plaques, blood clots.

To the doctor and examine!

3. Why how many times measure pressure, the tonometer shows different numbers?

Because the pressure is not a permanent value. Talked, sat down, got up, looked like, filed, recovered - all this is reflected on the pressure.

So doctors recommend to spend three measurements with an interval of 2-3 minutes and take the average value. In many modern tonometers there is such a function: the device itself calculates the average pressure. It is very important if you measure pressure 3 times in a row, make this 2-3 minute break between measurements. The vessels must relax from squeezing and recover. Otherwise, the results will be incorrect.

4. Why when pressure measures me a doctor, I have other numbers?

Because in the clinic it is impossible to create conditions for proper pressure measurement (see above). At the doctor's reception you, one way or another, nervous. There is even such a term: "White Kolata Syndrome. Therefore, more faithful measurements of hell - in a relaxed home setting.

5. Are more expensive tonometers (within one brand) more accurate?

Not. They are all accurate, and their price depends on the set additional features.

6. Why is the Japanese tonometer done in China?

Because in this country - cheap labor. If it were collected in Japan, it would cost two times more expensive. There is a huge difference between handicraft Chinese production and factory. The assembly of tonometers occurs under the tight control of Japanese specialists. Certificates of the Ministry of Health and Gosstandart are talking about the quality of tonometers. And the life of the instruments reaches 20 years.

At this I will turn out.

P.S. The full algorithm for the sale of a tonometer I cite in my book "ABC of pharmacy sales". Details

It is not always convenient - after all, to independently get with their help, the exact data is very problematic.

Fortunately, the medical industry has long started to produce digital devices, which are incomparably more convenient to use than traditional analog. Digital devices for measuring blood pressure on the wrist are especially comfortable.

With it, you can quickly find out the parameters of your own hell, without resorting to any help. However, in the use of such devices there are certain rules, not knowing which data can be obtained that do not reflect the true state of the body.

In general, the accompanying instrument for measuring the pressure on the wrist reviews are quite high. But who is suitable for such a device, how to measure the pressure with a tonometer on the wrist and avoid characteristic errors that make the result inaccurate?

Environmental temperature affects the indicators of a custody tonometer.

How to measure the pressure with a tonometer on the wrist?

Before changing the pressure on the wrist, it is necessary to carry out a small but important training.

For half an hour before, before changing the pressure to the device on the wrist, you can not drink alcohol, as well as smoking, perform physical work or play sports. If you feel calling, you need to visit the toilet.

Pressure measurement cuff must be placed on a naked wrist. It is impossible to have clothes, jewelry and the like items between the cuff and the body - this can affect the correctness of the result.

An important meaning is the ambient temperature.

It is impossible to measure in the cold when the temperature is below 16 degrees - the indicators will be inaccurate.

The wrist with the cuff must be placed at the chest level. If the hand is located below - it is possible to increase the pressure indicators. If the hand is located above the level of the heart - the indicators will be understated.

It should be remembered that:

full bladder increases 15 mm pressure. RT. st.;
the absence of back support increases the same figure by 10 mm. RT. st.;
if the wrist is located not at the breast level, each 5 cm deviations change the pressure indicators per 1 mm. RT. Art.

In this regard, despite its numerous advantages, for some groups of people, there will be no waterproof the best choice. For whom, the devices for measuring blood pressure on the wrist are a reasonable choice, and who is better not to acquire this device?

During measurement of pressure, breathe calmly and smoothly.

Choose with the mind

Given the pros and cons of a similar type of tonometer, it can be recommended primarily to those who often and for a long time in road and business trips and for whom the compactness and universality of the device are important.

A custody clarity tonometer will suit those who need to very often control the indicators of its pressure, because it is very easy to prepare for work.

All you need is to wear the device on the wrist, then press the power button. Also, such a type of tonometer is convenient in the case when a person suffers excessive completeness. After all, if the cuff for measuring the pressure is too narrow and blends greatly, the tonometer indicators will be incorrect.

Do not purchase a similar tonometer to the people of old age.

After all, it can be difficult for them to hold the arm at the breast level in the process of measuring blood pressure.

In addition, many people in old age cannot normally control the motility of the hands, and their shaking and other involuntary movements reduce the measurement accuracy.

Finally, the crew tonometer should not be used with expressed atherosclerosis. Problems with veins arising from this disease do not allow the device to normally perform their functions.

It is better to choose certified products of well-known manufacturers - they give more accurate readings.

Video on the topic

How to measure the pressure on the wrist and on the shoulder? Answers to video:

However, even with these problems, the use of a blinding thermometer is possible. It is necessary to measure the pressure by the apparatus on the wrist, and then, immediately after that - the usual tonometer. If the readings coincide - you can safely acquire this convenient and in many cases an indispensable device.

Blood pressure control for modern man - This is a basic element of medical culture, a sign of responsibility for their health. For certain categories (people over 50 years old, hypertensis, athletes), the systematic measurement of blood pressure becomes vital. Along with traditional apparatus with a shoulder fastening, compact bracelets have now been distributed, allowing to control the pressure outside the house - on the way, in the workplace, in the stadium or in the gym. Local on behalf of: Are such products enough to be accurate than guided by their choice, what a tonometer on the wrist is better to purchase?

Since electronic devices based on an oscillometric method appeared, attempts began to register blood pressure in the wrist area. But it turned out that the results of measurements in people after 40 years did not correspond to reality. The error was explained by the changes in the vascular walls: they thicken with age, so it was difficult to catch the amplitude of air pressure fluctuations that arose in the cuff during blood flow through a compressed section of the artery.

Progress has come when a tonometer, according to the will of scientists, "learned" to recognize the ripple not one, and the two arteries over the brush hand. In addition, the cuffs and the electronic unit of the device were upgraded. Nowadays, the pressure meter on the wrist is practically not inferior to the shoulder analogue, although the doctors still consider the accuracy of tonometer bracelets insufficient and include this figure to its minuses.

Chatting apparatus and a number of unconditional benefits:

small sizes;
low weight;
mobility and autonomy;
adjustable cuff;
lack of tubular compounds.

The device with the cuff on the wrist is able to perform its functions in any conditions, without delivering the inconvenience to the user. To measure blood pressure, you do not have to free from clothes the entire surface of the shoulder, search for a solid support for the forearm.

We have already written that as a result of one of the research, doctors concluded that most negative reviews about the wrist tone meters are connected with the fact that people simply do not know how to measure pressure.

At the same time, the accuracy of gadgets and the adequacy of testimony that was rechecked in clinical conditions does not doubt. Let's deal with how to correct the pressure on the wrist.

To whom it is convenient

As a rule, the wrist is recommended to measure up to 40-45 years, and shoulder - already for older people. The fact is that the vessels on the wrist over time lose elasticity, therefore the risk of a big error. The second reason is an atherosclerosis of the arteries, in which the testimony can also be inaccurate.

Well, finally, in some cases, deviations, for example, tremor can break down the measurement process in one or the other side.

Than measuring

Today there are a number of aspirations to make the process of measuring pressure less "traditional". Attempts to create a "tonometer-clock" are undertaken systematically. Here are just a few gadgets that came close to this: the Taiwanese company rootiped W / ME2 with the calculation of pressure in the propagation rate of the pulse wave.

Most of all approached, it seems to this format in Omron. At the last CES2018 exhibition, the working prototype of the clock-tonometer has already been shown!

Despite all efforts while the only reliable device for measuring the pressure on the wrist is a tonometer! They are sold in pharmacies, doctors trust them, their accuracy is confirmed by hundreds of clinical trials.

Digital tonometer on the wrist

The technique is mistaken, but the person is even more often, so now the trend is that the recommendations in favor of digital tonometers that would exclude the human factor in measurement: they themselves pumped themselves, they themselves blow themselves, they themselves do everything and show the data on the display.

At the same time, a good apparatus for measuring pressure on the wrist should now have several more advantages:

Big numbers
The function of identifying arrhythmias!
A clear charge indicator to exclude the accumulator error on time.
Color Scale World Health Organization

The latter is needed that the user in everyday life can interpret the results, and in the case of high values, when the arrow will indicate an orange or red, could consult a doctor for clarifications.

Memory

Everything is relative. To do a little, it is important to keep it and compare with other measurements, and not numbers to numbers, but also behavioral features on this day, nutrition, walking ... Simply put "remember everything", which could directly or indirectly influence testimony.

Built-in memory for dozens of measurements is usually provided in digital models.

Several models to choose

Among the tonometers on the wrist with such parameters, several popular medical models can be distinguished:

A clear display and compact dimensions, simple measurement and pressure, and pulse, as well as the patented Intellisense technology - painless injection.

This tonometer has built-in memory for 30 measurements and guarantees accuracy when complying with all rules +/- 3 mm RT. Art. Due to the flatter design of the main digital part looks easier and more compact!

Tonometer on the wrist from the famous Japanese manufacturer of medical equipment. The main concept implemented in this gadget is simplicity. Access to the measurement is carried out by one button, which allows you to measure quickly and understandably.

How to measure

For readings to be accurate, it is necessary to follow a number of conditions. It is not difficult to physically prepare for measurement: enough for 20-30 minutes to the measurement to be in peace.

We are not talking about intentionally to turn ourselves to "Ameba": it's just enough to engage in ordinary affairs in normal mode, not subject to pressure loads.

The pressure tonometer on the wrist can be measured and sitting, and standing. The sensor with the display should be rotated "face to itself", and the cuff is placed at a distance of about 1 cm from the palm.

In this case, discrepancies with the shoulder structures that are considered as if "more reference" will not exceed the permissible norms, usually 5 - 6 - 7 units.
