Which tonometer is best for home - what you need to consider when buying a device. Which tonometer is more accurate and reliable? The smallest tonometer

Every person with a tendency to high blood pressure should have a home blood pressure monitor. This is especially true for older people, who often face hypertension and other cardiovascular diseases. The choice of tonometers is very large. Many people prefer a wrist tonometer, primarily because of its compact size. However, this type of pressure meters has a number of disadvantages that you should familiarize yourself with before purchasing.

A wrist blood pressure monitor is a small device with a narrow cuff. Automatic device does not require any unnecessary manipulations. The person simply places the cuff on their arm and presses a button. Air enters the cuff automatically from an electronic compressor, and the data is displayed on the monitor.

The wrist pressure tonometer has the following advantages:

• compact dimensions;
• mobility;
• ease of use;
• affordable price;
• long service life.

It is convenient to keep it always at hand. Automatic wrist blood pressure monitors can be easily carried in your bag and monitor your blood pressure in any conditions. The device can have two types of power supply at once - a rechargeable battery and regular AA batteries. This allows you to take it with you on trips.

An electronic wrist blood pressure monitor is relatively inexpensive compared to automatic models with a brachial cuff. It is the cost of the device that often becomes the decisive criterion when choosing a tonometer for the home.

Inexpensive wrist blood pressure monitors are highly reliable and have a fairly long service life, of course only if they are made by a reliable manufacturer. In addition, the warranty period for the use of such devices is two years or more, which is a good indicator considering the cost of the tonometer.

Despite its compact dimensions, the screen of such a device is quite large, the numbers are displayed clearly, so many people prefer a wrist tonometer for older people.

The main advantage of a wrist tonometer is its compact size.

Disadvantages of the device

It would seem that a compact and inexpensive tonometer with a narrow cuff is the best choice for home use. From the point of view of practicality, everything is so, but as a medical technology, a tonometer on the wrist is not the best option. Its main drawback is the questionable accuracy of measurement. This is due to the design of the cuff.

The narrow cuff fits the wrist quite tightly. When air enters it, compression of the radial vein occurs. Gradually, the air leaves the cuff, the pressure on the vein is weakened and the pressure is measured. That's what it's all about the main problem such devices - the radial vein is too thin, the amplitude between compression and relaxation is small, so the pressure value may be unreliable.

In addition, wrist blood pressure monitors require correct operation. When measuring blood pressure, the hand with the cuff should be held exactly at heart level. Such tonometers “fib” if you lower or raise your hand a little. In this case, the deviation can range from several millimeters of mercury to tens of percent. In the first case, this is not important, since at a pressure of 145 and 148 mmHg. the same measures are being taken. But if a person’s blood pressure is 160 over 100, and the tonometer shows 145 over 90, this can become a serious problem in treating hypertension and monitoring the dynamics of pressure changes.

Automatic blood pressure monitors can be equipped with various functions, which affects the cost of the device. The basic set of functions is the measurement of upper and lower pressure, as well as pulse rate. Thus, after measuring the pressure, three numbers are displayed on the screen. If a person has arrhythmia, the tonometer data will be incorrect. In addition, some models simply will not work if there is an arrhythmia, and a measurement error message will be displayed on the screen.

It is precisely because of sensitivity to arrhythmia that wrist tonometers are considered not the most best choice for older people who are often diagnosed with this problem.

Models of this type show incorrect results for cardiac arrhythmia

Who is this tonometer suitable for?

A brief summary of the features of wrist tonometers will help you understand in what cases to use them.

The following characteristics are in favor of purchasing this device:

• ease of operation;
• mobility and compactness;
• affordable price.

“Against” a compact tonometer are:

• sensitivity to arrhythmia;
• sensitivity to the position of the arm with the cuff;
• measurement inaccuracy.

At the same time, discrepancies in real pressure values ​​and numbers on the tonometer monitor depend on a number of factors - body position, device charge, pulse, arrhythmia.

Thus, it becomes clear that a compact tonometer cannot be the main and only means for monitoring blood pressure values ​​at home. A wrist sphygmomanometer is a good, and sometimes better, choice for measuring blood pressure. It is convenient to take it with you on a trip, to work, or on a business trip for those who need to constantly monitor their blood pressure.

Advice from cardiologists: for home use, you should choose a blood pressure monitor with a shoulder cuff. A wrist cuff device is suitable as a mobile blood pressure monitor, but is not suitable for precise blood pressure monitoring.

In addition, there is a more convenient alternative to this device - fitness bracelets with a heart rate monitor and blood pressure measurement. Such devices also suffer from a slight measurement error, but are intended for constant wear, as they look like a sports watch with a silicone strap.

A fitness bracelet performs the same functions, but looks like a stylish accessory.

Useful functions of wrist tonometers

If a person decides to opt for a wrist tonometer, he should understand the features different models. Pricing of tonometers largely depends on the set of functions. In addition to two main functions (measurement of blood pressure and pulse), the tonometer can have:

• large amount of memory for storing data;
• built-in calendar and clock;
• sound notification about turning the device on and off;
• combined power supply (battery and batteries);
• large color monitor;
• voice recording of measurement results.

Some of these functions can be abandoned in favor of the cost-effectiveness of the device, but here you must first decide for what purpose the tonometer is being purchased. If the device will serve as an auxiliary meter, and you have a full-fledged tonometer with a shoulder cuff at home, you can safely purchase the simplest basic model. At work or on a short business trip, a person will have enough simple measurement pressure and pulse, additional functions will not be used.

There are wrist blood pressure monitors for the elderly, as this device may be more difficult for an elderly person to operate. When choosing a tonometer for a person over 65 years of age, one should take into account the acuity of his vision, hearing and memory. For people who have difficulty seeing, a device with a voice function for reading measurement results would be an excellent choice. If a person has a hearing problem, but his vision does not fail him, this function can be easily abandoned.

Often, for older people, doctors prescribe regular blood pressure measurements every day, for example, every day after meals, before going to bed, and immediately after sleep. So that a person does not forget to take measurements, the right choice will be purchasing a device with a reminder function. Simply put, this is a regular alarm clock built into a tonometer that will emit sound signal at a given time, reminding the hypertensive patient that it is time to take measurements.

The need for a large amount of memory in a tonometer is a controversial issue. Elderly people are usually instructed by cardiologists to keep a diary of measurements and it is easier for them to do this manually, armed with a regular notepad and pen. For middle-aged people, the function of storing data in the device’s memory often also plays a secondary role, since pressure is measured more for prevention than for the purpose of making a diagnosis. Everyone decides on their own whether they need a function for storing measurement results.

The built-in memory will be convenient if several people use the tonometer at once. More advanced models allow you to customize the device for each family member individually. In this case, when measuring pressure, you will need to select the parameters previously entered into the device’s memory and take the measurement, and the smart tonometer will record the results in the desired directory.

If you plan to use the device at home, it is better to purchase a model with an adapter so as not to buy batteries

Main selection criteria

In modern economic realities, the main criterion for choosing a tonometer is its cost. Here you need to understand what a person pays for.

If a tonometer has all imaginable and inconceivable functions, but costs an order of magnitude cheaper than its analogues, there is definitely no need to purchase such a device. Usually they offer greater functionality and minimal cost Chinese manufacturers with an untranslatable name. Such devices fail in a matter of weeks, and the measurement results certainly cannot be trusted.

If you want to save money but buy a quality device, you should pay attention to Nissei devices. A tonometer with a minimum of functions will cost a relatively small amount, but will serve faithfully for at least 5 years.

Another important criterion is the method of powering the automatic or semi-automatic blood pressure monitor. It’s better to pay a little extra and purchase a device with a mixed type of power supply, which is equipped with a rechargeable battery, but can also work from ordinary AA batteries. A tonometer with one battery is not always convenient to take on a trip, and devices that are powered only by batteries begin to “lie” as they fail.

Is this type of blood pressure monitor suitable for the elderly?

Nothing prohibits purchasing a wrist tonometer for an elderly person. But cardiologists strongly recommend leaving these devices for relatively young people leading an active lifestyle. The main advantage of a wrist tonometer is its compactness and mobility; older people usually do not need it. In this case, it is better to give preference to reliability and accuracy of measurement, but not to ease of use.

For older people, blood pressure monitors with a wide cuff designed for the shoulder are recommended. At the same time, the most accurate, affordable and reliable are semi-automatic devices with a mechanical compressor. In addition, they work great even with arrhythmia, taking additional measurements and showing the average value.

Rules for using a wrist tonometer

If a tonometer is used on the wrist or for the hand, the instructions for use must be followed exactly - this will allow you to achieve the most accurate measurement values.

1. When choosing a tonometer, the diameter of the hand is taken into account. The cuff must fit the patient's arm exactly. A cuff that is too wide or too narrow will distort the value results.
2. Before measuring pressure, make sure that the battery is infected. Otherwise, the accuracy of the device cannot be trusted.
3. Having installed the cuff on your wrist, you should rest your hand on a hard surface and hold it at heart level, and only then press the button to start measuring, or start pumping the bulb.

The rating of wrist tonometers will help you choose the best option. You can always test a device you like at a medical equipment store or pharmacy that sells the device. Moreover, it is recommended to simultaneously measure the pressure with a wrist tonometer and a reference device with a shoulder cuff, which is used to calibrate tonometers in specialized stores - this will determine the maximum degree of discrepancy between the values.

Best models

The most affordable, reliable and easy to use is the AND UB-201 tonometer. There is only one button on the device, which starts the cuff inflation process. The main advantage is the large battery charge indicator, which is hard to miss. One set of batteries provides 400 pressure measurements. The downside of the device is that it is not intended for older people. In terms of price, this tonometer is the absolute leader in the rating - its cost ranges from 1200 to 1400 rubles. There is also a more modern model UB-202 on the market, equipped with many useful functions, for which you will have to pay about 2500 rubles.

The peculiarity of AND UB-201 is the presence of only one button

Medisana HGF is a compact automatic wrist tonometer that “can” recognize arrhythmia. In this case, it makes a series of measurements and displays the average value. A fairly comfortable and high-quality device that will last for many years. The cost is a little steep - about 2000 rubles. The main disadvantage of the device is that it is difficult to find on sale.

Medisana HGF can be used even for arrhythmia

The Nissei WS-1000 is an affordable and reliable automatic wrist pressure monitor. It is a sales leader, as it is represented in most large pharmacy chains. The obvious disadvantages of the device are that it is powered only by batteries and the complete lack of additional functions. The main advantage is the cost of about 1,500 rubles and a five-year warranty from the manufacturer.

Omron R5 Prestige is an advanced model with many additional features and an impressive amount of memory. The cost of the device is about 5 thousand rubles. The main advantage is that it is made in Japan.

Content

The most important event for effective treatment hypertension is to measure blood pressure (BP) at home. If a patient with hypertension does not regularly carry out this procedure, then there will be little sense in the treatment, and everything in the end may end sadly. To carry out the measurement, a device called a tonometer is used. It should be in every home, because... Blood pressure surges occur in people of any age, especially the elderly. In this case, it is very important to find the most accurate pressure meter.

What is a tonometer

A tonometer means a medical diagnostic device for blood pressure: the diastolic norm is 80 mm Hg. Art., and systolic – 120 mm Hg. Art. This device is otherwise called a sphygmomanometer. It consists of a pressure gauge, an air pump equipped with an adjustable release valve, and a cuff that is placed on the patient's arm. Today you can order a suitable device from online pharmacies with delivery. It may differ in the following parameters:

• type (mechanical and electronic, automatic and semi-automatic);
• cuff size;
• display (dial);
• accuracy.

What is it needed for

Normal indicators can deviate down and up by no more than 10 mm. rt. Art. If the deviations exceed them, this indicates that the patient’s cardiovascular system suffers from pathology. If blood pressure is constantly elevated, then this is already a hypertensive disease, which is fraught with heart attack and stroke. For correct therapy, daily blood pressure monitoring will be required, which is performed using a tonometer. This device helps:

• Constantly monitor the results of treatment when taking pills prescribed by a doctor or using other methods of therapy;
• in case of deterioration of health (headaches, dizziness, nausea, etc.), determine in time a sharp jump in blood pressure and take appropriate medicinal product;
• control changes after switching to a healthy lifestyle: joining sports, giving up alcohol, smoking, etc.;
• do not waste time visiting a medical facility, but take measurements at home;

It is recommended to have the device in the home medicine cabinet for all those people who suffer from heart disease, diabetes, vascular pathologies, experience constant stress and psycho-emotional stress, and have hormonal disorders. In addition, the device will be useful for those who often drink alcohol and smoke, as well as for athletes for proper control over physical activity and for older people due to general deterioration of health. If indicated, frequent blood pressure measurements may be recommended for pregnant women.

Classification of pressure measuring devices

To choose a device that is easy and convenient to use, read the classification. Groups of devices according to the degree of patient participation in the measurement process, the location of the cuff and functionality are presented below. It would be possible to separately classify devices by manufacturer, but the issue of choosing a brand is not the main one, because Most of the production of foreign medical equipment is located in China.

According to the degree of patient participation in the process

It is believed that the first instruments for measuring pressure appeared in Austria in 1881. In those years, pressure was measured using a mercury manometer. Subsequently, the Russian surgeon N. S. Korotkov described a method for measuring systolic and diastolic sounds by listening. Which tonometer is accurate: over time, mechanical devices began to give way to semi-automatic devices, which later began to be crowded out by automatic devices. The difference between all three options is the degree of patient participation in the measurement process:

• Manual. Inflating and deflating air is done manually using a bulb. The pressure is determined by ear with a stethoscope, looking at the arrow readings on the dial.
• Semi-automatic. The air is pumped up by a bulb, and the pulse and blood pressure are indicated on the display without the use of a stethoscope.
• Automatic. Air is pumped in by a compressor and released by a valve. The result is shown on the display. The automatic tonometer works from the mains using an adapter or on batteries.

According to the method of cuff placement

An important factor is the location of the cuff and its size. This element consists of fabric (mostly nylon) located inside the pneumatic chamber and fasteners (fasteners) in the form of Velcro. The inside is made of medical rubber. In order to squeeze the patient’s hand and block the blood flow through the vessels to determine the exact indicator, this element is filled with air. Depending on the model, this element is located on the shoulder, wrist and finger:

• On the shoulder. The most common option that suits all age categories. Online stores offer a wide range of cuffs from children's to very large.
• On the wrist. Optimal only for young users, especially in the case of monitoring blood pressure during increased physical activity during sports activities. In older people, readings may be incorrect. In addition, it is not suitable for tremors, diabetes, vascular sclerosis.
• On the finger. The simplest, but least accurate option. For this reason, it is not considered a serious medical device.

According to the availability of additional functions

Simpler and budget models do not have any additional functions, but their presence can be a good plus in favor of choosing a specific tonometer. The more functionality, the easier and more convenient it is to measure blood pressure. Modern high-tech devices may have:

• Memory capacity, which in most cases is designed for 1-200 measurements. Thanks to it, the device will store information about all measurements taken - this is especially necessary if the device is used by several people.
• Diagnosis of arrhythmia, i.e. rhythm disturbances. In this case, the data will be displayed on the informative display. Additionally, there is a sound signal.
• Intelligent control, or Intellisense system. A function that can minimize the likelihood of error in the presence of cardiac arrhythmia. Found only on expensive models.
• Voice announcement of the result. This function is very important for patients with vision problems.
• Prompt display. Beginner-friendly feature. It shows the user whether his blood pressure is normal or not using color.
• The function of taking several blood pressure measurements in a row (often 3) with the calculation of the average value. This feature is necessary for atrial fibrillation, i.e. atrial fibrillation.

How to choose a tonometer for home use

The selection algorithm is simple. It is important to decide specific type device, taking into account the frequency of use of the device, the age of the patient, the presence of cardiovascular diseases, etc. Which tonometer is more accurate - selection criteria:

• Frequency of operation and number of users. An automatic or semi-automatic device is suitable for frequent use, but if the number of users is more than one, it is recommended to choose a model with a memory function.
• Age category of the patient. Both shoulder and wrist pressure gauges are suitable for young and middle-aged people. An elderly patient should choose exclusively the shoulder. This is due to the fact that the vessels of the wrist joint wear out over time, the elasticity of their walls decreases, arthrosis (joint diseases) occurs, and bones begin to appear. All these factors can distort the accuracy of blood pressure measurements.
• Cuff size. The most popular are shoulder products - the shoulder in medical terminology means the area from the shoulder joint to the elbow. This type is available in several sizes, some of which are universal, others are suitable only for children or adults. Approximate breakdown in the table:

• Presence of cardiovascular diseases. If the patient has problems with heartbeat (arrhythmia), then preference should be given to a device with an intelligent measurement function.
• Ability to measure pressure yourself. A mechanical sphygmomanometer is only suitable for doctors and nurses who know how to use it, because while measuring blood pressure you need to listen to the pulse with a stethoscope. For this reason, you should choose a semi-automatic/automatic machine for home use. It is stuffed with sensitive electronics, which will accurately determine your pulse.
• Company manufacturer. Popular manufacturers of pressure meters include AND and Omron (both Japan), Microlife (Switzerland), Beurer (Germany). Moreover, AND has a patented technology for oscillometric blood pressure measurement - it was the first to receive a patent for this technique, which is used in digital devices. Omron actively promotes its products among the Russian-speaking audience, which has a positive effect on the company's business.

Which blood pressure monitor is the most accurate?

The most accurate is a mercury device, because Pressure by definition is measured in millimeters of mercury (mmHg). They are practically not sold in pharmacies, they are bulky and have all the disadvantages inherent in hand-held meters. It is very difficult to measure blood pressure yourself using a hand-held device - you need to have skills, good hearing and vision, which not all patients have. In addition, once every six months you need to perform calibration (adjustment) in a special center.

An automatic device can lie, it has some error (often stated about 5 mm), but in most cases this is not critical for selecting therapy. There are no alternatives to automatic blood pressure meters for use at home, you just need to be able to use them correctly. Which tonometer is more accurate: according to experts from the country’s calibration laboratories, the percentage of incorrect measurements is:

• 5-7% for AND, Omron;
• about 10% for Hartmann, Microlife.

Mechanical

To find out which tonometer is accurate, pay attention to mechanical devices. They consist of a shoulder cuff, a pressure gauge and an air pump with an adjustable valve. Blood pressure readings are determined by listening to characteristic sounds through a stethoscope. In this case, blood pressure is measured by a person who has the appropriate skills, so this type of equipment is recommended for healthcare workers. It is often used in public health facilities such as hospitals. Which tonometer is more accurate - popular models:

• Healthcare CS-105. High-precision mechanical device in a metal case from CS MEDICA. There is a built-in phonendoscope, a cuff (22-36 cm) made of nylon with a fixing metal ring, an elastic bulb with a needle valve and a dust filter. The kit includes a case for convenient storage of equipment. Relatively cheap (870 RUR).
• Healthcare CS-110 Premium. A professional device, the pressure gauge of which is combined with a bulb. Made in a shock-resistant polymer case with chrome coating. An enlarged cuff (22-39 cm) is used without a fixing bracket. There is a large and easy-to-read dial, a pleasant-to-touch pear with a chrome-plated release valve. The measurement accuracy is confirmed by the European standard EN1060. It costs more than its analogues (RUR 3,615).
• Microlife BP AG1-30. This high-precision sphygmomanometer consists of a bulb, an air release valve, and a storage bag. A professional cuff (22-32 cm) with a metal ring is used. The model is popular among domestic doctors. A distinctive feature is the stethoscope head sewn into the cuff. It is inexpensive (1200 rubles).

Operating principle of the sphygnomanometer

When measuring, the stethoscope must be applied to the inside of the elbow. After this, the specialist needs to pump air into the cuff - he does this until, due to compression, the blood pressure level drops to 30-40 mm Hg. Art. greater than the estimated systolic pressure (upper limit) of the person being tested. The air is then released slowly so that the cuff pressure decreases at a rate of 2 mmHg. per second.

Gradually falling, the pressure in the cuff reaches the patient's systolic value. At this moment, noises called “Korotkoff sounds” begin to be heard in the stethoscope. Diastolic pressure (lower) is the moment when these murmurs end. The operating principle is as follows:

• When the air pressure in the cuff is pumped up and exceeds the same parameter in the vessels, the artery is compressed to such an extent that the blood flow through it is suspended. At this time there is silence in the stethoscope.
• When the pressure inside the cuff decreases and the lumen of the artery opens slightly, the blood flow resumes. At this moment, Korotkoff sounds begin to be heard in the stethoscope.
• When the pressure stabilizes and the artery opens completely, the noise disappears.

Pros and cons of mechanical devices

Which tonometer is more accurate? When answering this question, a mechanical device is in the lead. Advantages of a mechanical device:

• impressive accuracy;
• affordable cost;
• reliable;
• suitable for measuring blood pressure even in patients with arrhythmia.

The main disadvantage is considered to be the difficulty of operation, especially for older people and patients with poor vision and hearing, impaired movement of the limbs - for them it will be a useless acquisition. To make it easier to measure blood pressure, some models include a cuff with a built-in phonendoscope head and a combined supercharger with a pressure gauge. For this reason, a sphygmomanometer can still be purchased for use at home.

Semi-automatic

Compared to a mechanical device, it has many differences, but has many similarities with an automatic one. In terms of price, the semi-automatic device is somewhere in the middle between the other two varieties. On sale you can find dozens of high-quality and durable mobile products of this type, among which the following have gained considerable popularity:

• Omron S1. A compact Japanese device for the shoulder, in which air is pumped using a rubber bulb. The results are displayed on a three-line display. There is a memory designed to store 14 measurements. The kit includes a logbook for recording data. The device is equipped with an indicator that flashes a signal on the display if the blood pressure level goes beyond the optimal range. Requires 2 batteries for power, no AC adapter. Cost – 1450 rub.
• Omron M1 Compact. Semi-automatic compact device for the shoulder, convenient and easy to use. Controlled with one button. There are all the necessary functions for quick and accurate blood pressure measurement. The memory capacity is designed for 20 measurements. Powered by 4 AAA batteries. There is no network adapter, it costs 1640 rubles.
• A&D UA-705. An upper arm device with the functions necessary for accurate and quick blood pressure measurements at home. There is an arrhythmia indicator, increased memory capacity that stores the last 30 results. Only 1 AA battery is needed to operate. The warranty lasts 10 years, but is more expensive than analogues - 2100 rubles.

How does it work

The semi-automatic device determines blood pressure and pulse in the same way as the automatic one. A distinctive feature is that the cuff must be inflated manually, i.e. rubber bulb. The list of their additional functions is more modest, but at the same time such a device has all the functionality necessary for measuring pressure. Many users and experts believe that a semi-automatic machine with a basic set is the best choice for home use.

Advantages and disadvantages

One of the disadvantages of the device is the need for manual pumping using a bulb, which is not suitable for weakened people. In addition, the accuracy of the data depends on the charge of the batteries and may also be affected by external influences. The advantages include:

• ease of operation compared to a mechanical analogue;
• affordable cost due to the fact that the device is not equipped with an electric motor, like an automatic model;
• The absence of an automatic air blower allows you to save money on the purchase and replacement of batteries.

Automatic

If the question arises about which tonometer is more accurate, consider the automatic device and the principle of its operation. The peculiarity of this type of device is as follows: all stages of blood pressure measurement are performed automatically. An automatic pressure meter appeared at the end of the last century. The user only needs to correctly position the cuff on himself and press the appropriate buttons - then the device will do everything independently. Additional functionality makes this procedure more informative and easier.

• A&D UA 668. The device is powered by batteries and mains, controlled by one button, has a function for calculating the average value, and an LCD screen. The memory is designed for 30 cells. There is no adapter included, it costs RUR 2,189.
• Microlife BP A2 Basic. Model with LCD screen, 4 AA batteries, mains power supply, 30-cell memory and motion indicator. There is a WHO scale and arrhythmia indication. It is inexpensive - 2300 rubles. There is no adapter in the set, which is a significant disadvantage.
• Beurer BM58. Model with memory for two users and 60 cells. There is a WHO scale, 4 batteries included. Can calculate the average value of all stored data, touch control buttons. Connection via USB is possible. It costs more than its analogues (RUR 3,700) and there is no adapter for mains power.

Principle of operation

Using an electric motor built into the body, air is pumped into the cuff independently to the required level. The electronic filling “hears” tones and pulsations, and then displays all the readings on the monitor. The machine is capable of measuring blood pressure not only on the shoulder, but also on the wrist and finger. Which tonometer is more accurate of these three - the first is more common, and the last is the least accurate.

Advantages and disadvantages

If you have a question about which tonometers are more accurate, read the pros and cons of the device. Advantages of the automatic device:

• eliminates the need for the user to pump air manually;
• convenient control, ease of use;
• expensive models are equipped with rich functionality, for example, they can be digital smart devices that synchronize with a smartphone and save measurement history.

How simpler device device, the more reliable and durable it is. In this sense, an automatic device is considered not the best choice:

• The service life is not as long as a semi-automatic. The electric motor is powered by weak batteries, the charge of which is quickly consumed, so it works at the limit of its capabilities and wears out quickly.
• It costs significantly more. Electronic filling is not cheap, and additional functionality further increases the cost of products.
• Machines designed to measure indicators on the wrist and finger have the least accuracy.

Rating of the most accurate blood pressure monitors

For treatment arterial hypertension(hypertension) and prehypertension (borderline state within 129-130/80-89 mmHg) you need to find out which tonometer is more accurate and reliable. The market is saturated with a large number of offers: some models have high-speed measurement due to the no-decompression method, others are equipped with a sensor correct position hands (APS) with indication (sound, light), from others you can download data to a computer via a USB port, etc. Which tonometer is accurate - reviews best models:

How to measure blood pressure

Approximately an hour before measuring blood pressure, the patient should refrain from smoking, consuming caffeine-containing products, or alcoholic drinks. During the procedure, you cannot talk or move, and your hand must be completely relaxed. The measurement is performed with the patient in a sitting position, no earlier than after 5 minutes. after he relaxes. Which tonometer is more accurate - instructions for using a mechanical (manual) device:

1. Place the cuff (standard/non-standard) on your arm at heart level so that it is 3-5 cm above the elbow.
2. Place the stethoscope on the center of the fold (inside) and put it on. After this, inflate the elastic element of the device to 200-220 mmHg. Art.
3. Then slowly (2-4 mm/sec.) deflate and listen through the stethoscope.
4. As soon as you hear the first blow, record the readings of the device - this is the upper pressure.
5. When you stop hearing beats, the recorded indicator is the lower pressure.
6. Take 2-3 measurements to calculate the average. Between a couple of procedures, take a 3-5 minute pause.

Many people, when answering the question of which tonometer is accurate, give preference to automatic (electronic) devices. They are expensive, but are easy to use. Instructions for their use are as follows:

1. Putting the elastic element of the device on your hand, place it at the level of your heart.
2. Then press the button on the device and wait until the automatic device gives you the current data. He will do all the work on his own, you just need to write down the readings received.
3. Be sure to take 2-3 measurements to determine the average value, which will be close to the real value.

As for the semi-automatic device, its operating principle is practically no different from its previous analogue. Which tonometer is accurate - both devices are practically no different from each other in this indicator. The only difference is that the user needs to pump up the air themselves, and this is physical work, which, according to experts, can raise blood pressure by 10-15 mm Hg. Art. In order to avoid such inaccuracy when using a semi-automatic device, another person must pump the air.

Sooner or later, everyone needs to measure their blood pressure. And if this need becomes systematic, you should think about buying a tonometer. In pharmacies, medical equipment stores and even supermarkets you will find a huge range of devices. How to understand the measurement chaos and make the right choice?

When is it time to look for a blood pressure monitor?

The belief that only very old people measure blood pressure is not true. In fact, a tonometer may also be needed at a young age, including completely healthy people. Thus, monitoring blood pressure levels is necessary for pregnant women. According to statistics, 5–20% of women in an interesting position develop hypertension. For them, a blood pressure monitor automatically becomes one of their essential items.

Blood pressure is also measured by athletes who exhaust their bodies with serious physical activity. Monitoring pulse and blood pressure in such cases is a necessary measure to prevent cardiovascular surprises.

And, of course, hypertensive patients. If you notice that your blood pressure may rise above 130/90, do not put off purchasing a blood pressure monitor. But first you need to understand which device to give preference to.

What is better - mechanics or automatic?

And the first question that buyers face is: what, besides price, is the difference between a mechanical and automatic blood pressure monitor?

Mechanical vehicles are among the most difficult to manage. To measure pressure with their help, you will need a keen eye that can detect the fluctuations of the pressure gauge needle, and a sensitive ear that will hear even a quiet sound at the right moment.

However, a mechanical tonometer also has undoubted advantages. It is considered the most accurate after mercury, which has already gone into oblivion. The mechanics allow you to record indicators with virtually no error, it can serve for many years, and its price is not at all annoying.

Automatic devices, of course, are more expensive, but they are much faster and simpler than their old counterpart, just as a motorcycle is more agile and convenient than a reliable but slow bicycle. And not everyone enjoys pedaling every day. At the same time, the accuracy of some automatic tonometers is almost as good as mechanical ones.

Also, unlike mechanics, all automatic machines measure your pulse. And the additional functions that especially “advanced” models are equipped with can even prevent a cardiovascular accident. But choosing a machine turns out to be not so easy.

The diverse world of electronics

Semi-automatic devices occupy an intermediate place between mechanical and automatic devices. The semi-automatic machine “hears” and “sees” itself, but does not know how to pump air into the cuff. Air pumping occurs in the same way as in mechanical models. The device will notify you with a gentle beep when you can stop vigorously squeezing the bulb and relax while awaiting the results.

In terms of accuracy, semi-automatic machines are practically not inferior to mechanics, and the difference in price between them is not so sensitive. Therefore, a semi-automatic machine is often the best choice for those who want to get maximum convenience with minimal material losses.

There are two types of slot machines - on the wrist and on the shoulder. Wrist blood pressure monitors look very ergonomic, but their accuracy leaves much to be desired. The vessels of the wrist have a small gap, and no electronics can accurately calculate the pressure from them.

Wrist tonometers are more often used by athletes who are not afraid of a small error in the readings. For hypertensive patients, it is better to pay attention to the shoulder machine. This is where accuracy and convenience are, “two in one”!

The brachial tonometer cuff is located on the shoulder, inside through which large vessels pass. This is why shoulder blood pressure monitors are very punctual. And, of course, an automatic machine is a convenience. The patient’s mission during blood pressure measurement is limited to securing and, after the procedure, removing the cuff. Oh, yes, you need to remember to press the one and only button, which will start the process.

What can an automatic blood pressure monitor do?

It would be too trivial if the capabilities of automatic tonometers were limited to measuring blood pressure and pulse. Electronics can do more! And before choosing a device, it is better to familiarize yourself with the additional functions and come to a conclusion whether it is worth paying for innovative developments.

The most common function that automatic and semi-automatic devices are equipped with is the diagnosis of arrhythmia. The tonometer monitors irregular heartbeats and, having identified them, signals danger. The device recognizes arrhythmia at the earliest stages, when you do not yet feel clinical manifestations. Therefore, determining arrhythmia is one of the most important functions for patients at risk: patients with hypertension and other diseases of the heart and blood vessels.

There are also tonometers that can detect atrial fibrillation- a common and very dangerous rhythm disorder. The most modern and, as a rule, expensive automatic devices are equipped with this function.

Another useful technology involves analyzing three consecutive measurements and producing an average result. It is no secret that the accuracy of an automatic tonometer largely depends on proper preparation for measuring blood pressure. To get the correct results, you should rest for 5-10 minutes before the procedure. You must be calm. During the procedure you cannot move, talk, or much more. By the way, these requirements apply to all types of tonometers - both automatic and mechanical.

However, if you did not have time to rest before the measurement, mechanics will still be more accurate than automation. The exception is devices that are equipped with a function for averaging three measurements. In one measurement, the tonometer manages to determine the indicators three times, process them and produce a “weighted average” and the most accurate result.

Don't rush to pay

So, you have decided on the type of device. What's next? Next, be sure to take a test measurement. Hold the tonometer in your hands and make sure that its parameters suit you. Check whether the standard cuff is long enough for you - for example, obese people have to be especially scrupulous in choosing it. If you have poor eyesight, pay attention to the size of the screen: the larger it is, the larger the indicators displayed on it.

Don't forget about the network adapter - it connects to all machines except wrist ones. For those who regularly measure blood pressure, the adapter is indispensable. Sometimes it is sold complete with a tonometer, but most often it is purchased separately.

When you have touched, held and tried on everything and the result of these actions has pleasantly pleased you, check another important point - the issuance of a warranty card. This document will protect you from manufacturing defects and will be a worthy conclusion to the difficult purchasing process.

Every year there are more and more people diagnosed with hypertension and hypotension. This means that they must keep their blood pressure under constant control. For this purpose, you will need a special device with which everyone can independently measure pressure. If you look at the range of tonometers presented for sale, you may get confused because of its diversity. But we will introduce future buyers to the rating of the best automatic tonometers to make it easier to choose the right device.

There is nothing complicated in choosing a tonometer, as it might seem at first glance. Its main function is to determine the volume of blood pumped by a person’s heart over a certain time and the resistance strength of his cardiovascular system. And in order not to make a mistake, you just need to adhere to the following criteria.

For whom is the purchase planned?. Different devices are ideal for different age categories:

1. To people up to 45 years of age if they do not have cardiovascular diseases, they should choose wrist tonometer. It is compact, so you can take it with you everywhere.
2. To people over 50 years old it's better to take on the shoulder, since they often have a weak pulse, and this multifunctional device will be able to probe it and give an accurate result.
3. For children Manufacturers have come up with special devices that are equipped with smaller cuffs. This makes them easier to use for a child’s small hands.
4. For pregnant Women also have special blood pressure monitors, since it is very important to regularly measure blood pressure in the second trimester of pregnancy to prevent the occurrence of preeclampsia.

Accounting technical characteristics . The tonometer should determine blood pressure as clearly as possible. There are a lot of positive reviews for devices that can operate from the mains and connect to a computer.

Let's sum it up

“In our family, one or the other member of the household began to experience high blood pressure at the end of winter and beginning of spring. And we bought a tonometer at the pharmacy, and on the advice of a specialist, we chose the Omron M2 Classic. We were convinced of the reliability of the device from this manufacturer. And they were right. The tonometer never lets us down and works properly. It is quite compact, when the batteries run out we turn it on from the mains. Provides results quickly and accurately, compared with other devices. I recommend Omron to everyone!”
Ekaterina, 39 years old.

“I had problems with blood pressure - I was diagnosed with hypertension. The question arose about buying a tonometer to measure your blood pressure at home. I chose the End UA-888 device. I was satisfied with its price, but when I figured it out at home, I was pleased with its functions. It is fully automatic, you just need to fix the cuff on your shoulder and press the button. The results are accurate. There is another important function - an arrhythmia indicator. It runs on four batteries, and I think a small drawback is that the UA-888 tonometer does not work from the mains. But I’m still happy with my device.”
Larisa, 52 years old

“I bought an Omron R2 blood pressure monitor on the advice of a doctor friend. I liked that the device is wrist-based. It came with a plastic box in which I store it. The tonometer is very compact, so you can easily take it with you anywhere. Powered by a pair of pinky batteries. Interestingly, it is equipped with a memory button, when I press it, the last few pressure readings are displayed on the screen. The device is very easy to use; it measures not only blood pressure, but also pulse. I recommend this necessary device to everyone!”
Olga, 35 years old

Both young and old people need to periodically monitor their blood pressure. And cardiovascular diseases are not always a companion to old age.

It is very convenient, quick and easy to find out your pulse and blood pressure using a tonometer on your wrist.

Compared to the classic device, which is mounted on the shoulder and has a built-in stethoscope, a wrist tonometer has a more compact size. In addition to the fact that such a meter performs its main function - it determines blood pressure, and with its help you can determine the pulse rate.

Some models have advanced functionality: they are able to save data for the last few measurements, and also have stress level sensors, comparative tables for determining deviations from the norm, and indicators.

Pros of a wrist tonometer:

• Portability. The meter, which is only slightly larger in size than a wrist watch, can be easily carried with you and used on the road.
• Accuracy indicators.
• Possibility of comparison data and determining the dynamics of changes.

Disadvantages of a wrist tonometer:

• Cuff length. The bracelet of the device, as a rule, has a length not exceeding 21 cm. Therefore, it is quite difficult for overweight people, children or those with very wide wrists to use such a meter.
• Age limit. Since the walls of the blood vessels located in the wrist area become less elastic with age, a tonometer on the wrist is not particularly suitable for older people - the measurement accuracy will be low.

Another feature of the device is that when taking readings, the arm with the device should be bent at the elbow and be at the level of the heart.

What to look for and how to choose

In order not to be mistaken in choosing an electronic or manual wrist blood pressure monitor and to determine which model is best for you, you should pay attention to the following:

• Focus and functionality. For older people, pregnant women, children or athletes, they differ in their range of functions.
• Guarantee period. Any device has its own warranty period, but for manufacturers of higher quality models it is no less, and sometimes even more than 5 years. If the warranty period specified by the manufacturer is 1-2 years or less, then you should refuse such a purchase.
• Cuff length. If you have a non-standard wrist width, then this fact should be taken into account first.
• Measurement error. Available for every meter. Its value is indicated in the description or passport of the device.
• Price. It depends largely on what additional functions the meter has. If you only need it to periodically monitor indicators, then you can abandon unnecessary “bells and whistles” and choose an inexpensive device.

If you plan to take measurements outside the home most of the time, then you need to choose one that can run on batteries or rechargeable batteries.

Possible additional functions

Important features that may be found in wrist pressure monitors include the following:

• Combination of automatic and mechanical operating principle. Some budget models have the ability to independently adjust pressure levels.

Number of cells in memory. This function is responsible for the device's ability to remember measurement data. The larger the memory capacity, the easier it will be to track the dynamics of changes in indicators.

This function is indispensable for those who suffer from cardiovascular diseases.

• Intelligent assistants and systems. It is sometimes difficult for older people to learn how to use various equipment. To avoid complications, some models can be configured with voice assistance.
• Availability of clock, alarm clock, calendar. Not always necessary and important functions, but for those who, due to circumstances, must constantly monitor their pulse and are also away from home, they can come in handy.
• Indicators. Indicators of arrhythmia, correct hand position during measurements, motion sensors - all this is responsible for the accuracy of the data. If you do something wrong when taking readings, you will be immediately notified about this by a special signal.

How to use correctly: instructions for use

How to correctly measure blood pressure with a portable tonometer on the wrist? The usage algorithm is simple and is as follows:

1. You need to remove the device from the packaging and turn it on.
2. Place it on the wrist of your left hand, tighten the cuff tightly so that it is tightly pressed to the wrist and does not twist. It is more convenient to measure pressure by turning the display towards the inside of your arm.
3. Place your bent left hand to the middle of your chest (where your heart is).
4. Wait a while. As a rule, many models give a sound signal that measurements have been taken and recorded. The waiting time is usually no more than 30 seconds.
5. Record the readings and remove the cuff.

There is nothing complicated about using a wrist meter. If the meter has a semi-automatic mode, then you need to increase the pressure manually (there will be a special button for this).

Average prices, frequently asked questions and answers

• When is the best time to take readings with a wrist tonometer?

  Blood pressure should be measured in a comfortable environment, 1-2 hours after eating, drinking alcohol or smoking. The cuff should be placed on the left arm.

• Which is better to choose a wrist blood pressure monitor: semi-automatic or automatic?

  There is no fundamental difference, but if maximum simplicity and speed of measurements are important to you, then choose automatic.

• What is the advantage of such a wrist device compared to the same mechanical shoulder device?

  It is not always convenient to use a mechanical device yourself, because only a doctor can accurately take readings. In addition, it is not suitable for people with poor hearing. This meter is small in size and much easier to use: it will do everything for you.

The simpler the tonometer, and the fewer additional functions it has, the cheaper the device will certainly be. The most inexpensive models can cost about 1,500 rubles, while the cost of the most expensive ones can exceed 6,000-7,000 rubles. On average, a high-quality and functional device will cost about 3000-3500 rubles.

To summarize the above, we can say that wrist tonometer is a very useful and necessary thing. If you are not one of those who cannot use such a device due to age or certain physical characteristics, then you can safely purchase it - it certainly will not lie idle.
