Watch bracelet for pressure measurement. The mechanism of action of smart watches with blood pressure and pulse measurement, indications, contraindications, review of models and rules of use

16.06.2019 Windows 7, XP

Global manufacturers of mobile electronics have made a real breakthrough by releasing smart watches with blood pressure measurement. A wrist gadget is gradually moving from an entertainment accessory into a vital necessity for some groups of the population. This smartwatch with a lot of useful features is equipped with sensors that allow you to measure not only your heart rate, but also your blood pressure.

Is it worth trusting the testimony

Many people are skeptical about the accuracy of blood pressure measurements using smartwatches. And completely in vain. It is enough to conduct a small experiment: measure the pressure first with a familiar tonometer, and then with a watch. Of course, all other conditions must be the same. The measurement must be taken on the same hand.

Based on the results of such experiments, it turns out that the discrepancy in readings is only 3-7 units, which is quite acceptable. Smartwatch manufacturers have set themselves the task of expanding the market for their products into the medical field, so accuracy of readings is a top priority. It is he who, as a result, will determine which of the brands will remain in this niche.

How to measure blood pressure correctly with a smart watch

Blood pressure, however, can be measured inaccurately by smartwatches. This will happen if the measurement is carried out incorrectly. When taking readings, it is necessary that the watch fits snugly to your hand and does not dangle on a loosely tightened strap.

This is due to the fact that the sensors necessary to record the pressure are located on the back of the watch, directly under the case. During the measurement procedure, they should be as close to the body as possible, then the readings will be as accurate as possible.

In addition, there are a number of rules that must be followed when measuring blood pressure with a smartwatch:

5-10 minutes before the procedure you need to remain at rest.
During the last hour, you should refrain from drinking tonic drinks such as alcohol, tea, coffee, cocoa, Coca-Cola. And also avoid smoking.
There is no need to talk during the measurement, which lasts 20-30 seconds.
The hand from which readings are taken should be relaxed and at rest. To do this, it is better to place it on a table or soft pillow.

By the way, the above rules must be observed not only when measuring pressure with a clock, but also with a stationary device. Even the usual tonometer will make a mistake if you violate the procedure.

What else can a smart gadget do?

Like all wrist gadgets, smart watches reveal all their functionality when paired with a smartphone. The vast majority of mini-devices do not have a SIM card slot, so communication with a smartphone is carried out via bluetooth.

A special application designed for a specific watch model is installed on the user’s smartphone. These apps are free and can be downloaded from popular stores such as Google Play or iTunes.

The application allows owners of smartwatches that measure blood pressure to take advantage of the following functions:

Pedometer. Using sensor readings, not only the number of steps taken is calculated, but also the distance.
Heart rate monitor.
Calculation of the number of calories consumed and expended.
Sleep phase monitoring.
A smart alarm clock that allows you to start a new day not at a given time, but at the optimal sleep phase for waking up.
Notifications about an incoming call, SMS or message on social networks and instant messengers.

Wrist devices for measuring blood pressure and pulse have a large and beautiful screen, about 1.3 inches in size, and good functionality. However, they are still different from traditional Smart Watches. The pressure measurement function imposes its limitations.

In smart watches with pressure you will not find, for example, the function of taking photos and videos, receiving calls and recording audio messages. Yes, and you can’t listen to music with their help. This accessory is tailored for other needs - health monitoring.

Review of smart watch models with pressure and pulse measurement

There are two large groups of wrist gadgets for measuring blood pressure: professional and for general consumption. Let's consider some models in more detail.

Omron Project Zero 2.0

Omron, a leading Japanese brand in the field of medical devices, has developed its own model of a wrist gadget. The model is equipped with a round screen and high-precision sensors. The specially developed Omron Connect US application allows you to control measurements not only from your watch, but also from your smartphone. Recommended for professional use.

Casio CHR-200-1

The Casio CHR-200-1 sports smartwatch also belongs to the professional field of use. Unusual and stylish design is the distinctive feature of this model. Perfectly monitors the heart rate of the cardiovascular system. The watch is equipped with a timer that operates in several modes and a notebook for recording readings. It has a battery with a very good capacity of 500 mAh.

GSMIN V6

This gadget is designed for a wide category of consumers. A large black 1.3-inch monitor and a white laconic strap give the watch a stylish appearance. In addition to measuring blood pressure and heart rate, the gadget is equipped with the function of a smart alarm clock and receiving notifications from your phone.

What is the value of a smartwatch with a blood pressure measurement function?

Despite the fact that watches are not a medical device and cannot serve as a replacement for a blood pressure monitor, they can still provide good assistance to certain groups of the population:

People suffering from hypertension. In this case, doctors recommend measuring blood pressure twice a day - in the morning and in the evening.
Gadget users with cardiovascular diseases.
Women during pregnancy.
People who frequently experience stress.

The watch is easy and intuitive to use. Even in old age, a person can easily master measuring blood pressure using a smartwatch. Unlike a tonometer, they are always nearby and are able to provide the necessary assistance.

You can conduct an experiment using a smart watch. You will need heart rate monitor data, sleep phase tracking, activity information and several blood pressure measurements throughout the day.

Over the course of several days, preferably at least a week, you will need to collect all the data.
Then, using the application on your smartphone, get graphs of changes in heart rate and pressure throughout the day.
Now, given your daily routine and physical activity schedule, you can find stressful periods.
Then you can observe how blood pressure and sleep quality changed after such exercise.
Draw appropriate conclusions.

Of course, a smart watch with blood pressure and pulse measurement is a very popular gadget that has long been expected in the mobile electronics market. And most likely this is just the first step into the field of health monitoring.

Tell a friend:

The market has been asking for smart watches with a blood pressure monitor for a long time, but manufacturers are in no hurry to send them into mass production. There are only a few high-quality models that could measure blood pressure. In this review, we will look at the most popular pressure measuring watches available for purchase in 2019. Looking ahead, we can say that there are very few watch models in the classic form, and there are even fewer of those that would measure blood pressure extremely accurately, so to complete the picture, we recommend paying attention to fitness bracelets with a tonometer, some of which we recommend using.

Herzband Elegance 2 – classic in fashion

The manufacturer decided to remove the popular Herzband Elegance from the assembly line and offer the market an improved model. Herzband Elegance 2 is very similar to its predecessor, the same classic with a round display and a leather strap. But this is only at first glance.

The first difference we can observe is the absence of a button on the side; now the screen has become touch-sensitive, or rather, a touch button has appeared on it, with the help of which all control is carried out. Whether this is good or bad is difficult to judge, it’s not for everyone, but in our opinion the button still gave a little classic to the watch, now they are more modern and are immediately associated with “smart” gadgets.

The second difference concerns the display itself, it has become color, which has made it possible to increase the readability of solar data by an order of magnitude, still far from ideal, but already acceptable.

The third difference, imperceptible to others, but noticeably noticeable to the owner of the gadget, is that the battery capacity has increased from 100 mAh to 170 mAh, coupled with an energy-efficient display, it was possible to extend the battery life of the watch to 10-12 days, which is 2-3 times higher than the readings of its predecessor.

Other differences. In addition to the main three differences, there are several more points worth highlighting. First, the function of measuring oxygen in the blood has been added; the operating principle of such devices can be read. Secondly, a mini-game has been added, it’s very primitive, but it will help while away 5 minutes of time. The third difference can be called a fly in the ointment in the overall range of improvements to the device; the price remained the same and for this we had to save money. Unfortunately, now the watch cannot boast of Gorilla Glass; it has a regular knee glass, which, by the way, still protects the watch quite well, but without a loud brand. The innovations of the model also include new colors, so in addition to the classic black and silver, blue was added, which looks very nice.

Unfortunately, the principle of measuring pressure remains the same, which sometimes leads to errors in readings.
In general, the device turned out to be of good quality, retaining almost all the positive properties of the first generation, while some aspects were noticeably improved.

Price Herzband Elegance 2 on average $55

Advantages: design, build quality, color display, energy-intensive battery

Flaws: errors in blood pressure measurement

Asus Vivowatch BP

Asus Vivowatch BP— new for 2019. This is essentially the first watch with a blood pressure monitor created by a famous brand that was actually put on sale not in words, but in deeds. Our editorial office has already received the first sample of this device and the first tests show good pressure measurement results, but more on that later.

Watch design it turned out to be very controversial, unlike any other analogues and cannot be confused with anything. The elongated horizontal shape with a bright metal circle creates a very unusual sensation. The design seems to tell us that this is not just another smart watch, but a medical device capable of measuring blood pressure very accurately. By the way, it is still not a medical device and you cannot rely on these readings with 100% accuracy, so there is no need to throw out a regular cuff tonometer.

Now about gadget functions, despite the fact that the main function is to measure blood pressure and pulse. The watch provides classic fitness tracker capabilities, as it allows you to track:

sleep quality (based on heart rate data);
calculation of distance traveled (based on GPS data and number of steps);
determining stress levels;
calories burned.

In addition to activity tracking, the watch notifies you of incoming calls and gives personal recommendations for normalizing blood pressure. An interesting feature is the aerobic heart rate indicator, which allows you to evaluate how successfully aerobic exercises have been performed.

In addition to all other advantages of the device, you can Attribute 28 days of continuous operation on one charge!

It’s too early to talk about accuracy, but the first tests show a very small discrepancy from reality, literally a couple of points, but there are still few reviews on the network for this watch, if you are the owner of the device, please write your review about the operation of this watch.

Price: starts from $200

Advantage: long battery life, accurate heart rate data.

Flaws: controversial design, high price.

Eastor CK11 watch

The Eastor CK11 watch has a slightly futuristic design with a curved display, the strap is made of silicone, but at the same time the watch looks quite elegant, although it does not reach the Herzband Elegance in this regard. The result is something between a fitness bracelet and a classic watch.

According to the stated functions, they are identical to the Herzband Elegance and are able to measure heart rate, sleep duration, steps, etc. The pulse is measured very accurately, but there are problems with data on sleep duration; they are not always shown correctly. The pressure is determined noticeably worse from the Herzband, but at the same time, a tendency for pressure to increase or decrease can be determined. What they lack in design and functionality they make up for with their low price, which is noticeably lower.

Protected to the same IP67 standard. No data was found on safety glass, so it's best to be careful when handling them.

Working hours 4-7 days

Price starts from $30

Advantages: rich functionality, low price

Flaws: strong errors in measuring blood pressure and sleep duration

The iNew H-One watch has a classic regular dial design. From afar, it will be very difficult to determine that this is a smart watch, and not just smart, but also capable of measuring a number of physiological indicators of the body, among which the pressure measurement function stands out clearly.

The case is made of 304 stainless steel, the strap is made of artificial leather. No data found for safety glass.

Charging occurs through a specialized docking station. The large and bright display makes itself felt, so the maximum battery life will not exceed 3 days.

The functions of the watch are identical to its counterparts, which were described above. The iNew H-One watch can measure heart rate, count steps, sleep, and physical activity. Regarding the most interesting function of measuring pressure, unfortunately the watch has not yet fallen into our hands and we have not found any reviews for this gadget. Therefore, from this side you will have to buy a pig in a poke.
The watch is protected according to the IP65 standard, which means it is dustproof and protected from direct jets of water; in fact, you can wash your hands and walk in the rain with it.

Working hours 2-3 days

Price starts from 100$

Wristwatch with blood pressure monitor Casio BP-100

The Casio BP-100 wristwatch with a blood pressure monitor dates back to the early 90s. This was probably one of the very first attempts to make a wrist gadget that could measure blood pressure. There are sensors on the front of the watch where you need to place your fingers so that the device can give readings about your heart rate and blood pressure.

This is what their box looks like:

And here you can take a closer look at them:

As a result of measuring your pulse and pressure, you will be able to see the following data:

At the moment, watches are no longer manufactured by the manufacturer, but if you are a vintage lover, used models can still be found on the Internet.

Price Casio BP-100 starts at $60

The principle of operation of a smart watch with a blood pressure monitor

To conclude the review, let’s look at how they work and how reliable their data is. Smart watch with blood pressure measurement they don’t read it in classical form, just like the same blood pressure monitors with a cuff do, everything is done more cunningly in roundabout ways.

First, the watch reads your data on the pulse, pulse wave velocity, ECG and other indicators, and then begins a software analysis of the received data. As a result of calculations, you receive data about your pressure on your watch display or on your smartphone. Often, you will first need to set your physiological characteristics: age, gender, weight, etc.

In order for the data obtained to be as accurate as possible, a number of rules must be followed:

It is best to take measurements on your left hand, although some manufacturers make it possible to measure on your right hand as well.
It is best to sit down and place your hand at heart level
It is not advisable to measure after eating
Before taking measurements, exclude all pacemakers from your diet (coffee, tea, energy drinks)
Try not to move or talk while measuring your blood pressure.
Enter all the required parameters about yourself into the application: age, weight, height, your normal blood pressure
More accurate measurements can be obtained through the app rather than the watch itself.

If it is not possible to follow these recommendations, simply stop, press the sensor to your hand or finger, depending on the modification, and wait while the device reads the data. In real time, as you perform the exercise, the accuracy of the pressure measurement may noticeably decrease.

Pressure measurement time with similar watches ranges from 30 to 120 seconds.

The accuracy of the readings varies depending on the rules followed and the model of the device. On average, devices show correct result in 80% of cases, deviations average 7-9 units.

Fitness bracelets with blood pressure monitor

Fitness bracelets with a blood pressure monitor are also deprived of attention from famous brands, and to find a working option you need to work hard. At the moment we can recommend the following models: Corband Fit, W/me2, H2, you will find more in our upcoming review of bracelets with a blood pressure monitor.

conclusions

Let's summarize our review of watches with a pressure measurement function. In general, such devices have a number of undeniable advantages over classic cuff tonometers.

So we can highlight the following:

1. Always have a tonometer with you
2. Multifunctionality of such devices
3. Affordable price, which is below the average for the smartwatch market
4. Detailed health analytics in the application, which will be useful to your doctor
5. Fast and comfortable pressure measurement, almost on the go

However, watches with a tonometer have one noticeable drawback, this is the fact that they do not measure pressure directly, but operate using workarounds that are heavily related to software, because a fair amount of reliability depends on the correctness of the calculations. Also, the reliability of the results can be affected by heart diseases, such as tachycardia, arrhythmia. If the manufacturer has not taken this into account in the software, the data will not be completely accurate.
Despite this drawback, a watch with a blood pressure monitor has the right to life and is suitable for many people who suffer from diseases with blood pressure. This gadget will also be useful for athletes who need to keep their blood pressure within a given range in order to ensure maximum results from their workout.

People do not always associate their discomfort, headaches, and constant tinnitus with increased blood pressure; they often attribute this to the consequences of overwork, troubles at work or at home. When they feel unwell, they try to change the situation on their own, forgetting to measure blood pressure.

As you age, your blood pressure usually increases. Blood vessels lose their elasticity, the lumens narrow and more and more effort is required to ensure the required blood flow, then blood pressure rises and it is necessary to take some measures to stabilize it. At the same time, the need for periodic or continuous blood pressure monitoring is growing.

What is it needed for?

Monitoring and diagnosing blood pressure does not require complex devices; its indicators are easily detected during a routine medical examination. And if the necessary treatment is started in a timely manner, in most patients, blood pressure can be corrected. Anyone can identify troubling signs of hypertension even without a medical examination.

Almost constant headaches of varying degrees;
Unexpected dizziness;
Tachycardia;
Frequent sweating, feeling of a pulse in the head;
Chills and anxiety;
Swelling of the eyelids, flickering spots before the eyes;
Frequent numbness of the fingers, morning puffiness of the face.

Signs appear periodically, but then they will become more frequent and the moment comes when a dangerous form of the disease is diagnosed. Don't wait for complications. Consult a doctor and strengthen self-monitoring of blood pressure.

Kinds

All types of smart bracelets serve one purpose - monitoring human health in such a complex area as the cardiovascular system. Therefore, it is almost impossible to create one device that would solve all control tasks in this system. In-depth diagnosis and treatment remains with specialists. But preliminary control of some indicators using smart bracelets is quite possible, and for this purpose, more and more advanced types of such devices are being created. Sometimes electronic bracelets are more accurate than stationary ones.

A modern tonometer bracelet records indicators that should be of interest to the attending physician. Modern bracelets, in addition to measuring blood pressure, can show body temperature, heartbeat, breathing rate and cholesterol levels in the blood. A system has been created that records emergency situations with elderly people, people with disabilities, and people with disabilities since childhood.

A bracelet for this category of people can immediately, through the warning system, warn relatives, guardianship authorities, and medical services. The device is worn by such people on the arm near the wrist and the QMedic system provides 24-hour communication between the elderly user and the caregiver. The elderly patient's condition is assessed around the clock.

When an emergency occurs, the patient presses the SOS button. QMedic paramedics address the elderly patient over speakerphone and, if necessary, call emergency services and notify family members. According to another program, if there are no signals from the patient for some time, then emergency assistance and a notification system for guardians also work. Another program is designed for people with poor memory and who do not know how to navigate urban or natural environments.

A W/me2 bracelet has been created to measure a cardiogram; its manufacturers claim that this cardiogram can be sent to doctors and used to assess their health. But using a cardiogram from 2 points, you can only determine the heart rhythm or its disturbances. Therefore, in order not to create illusions, it is better to entrust the cardiogram to specialists.

Massive passion for jogging in the morning and evening can generally be useful, but everyone must determine the limits of what is possible for themselves. You shouldn’t chase personal records and increase the load on your own. There is no need, as in sports, to be the fastest. Small loads under the control of primarily doctors and the numerous electronic devices created are sufficient.

An interesting and useful development of a fitness bracelet. It operates with a pressure and pulse sensor according to a specially developed program. All data on pressure, pulse, distance traveled in kilometers is displayed on a PC or smartphone, as well as on the screen of this device. A fitness bracelet with a screen, in addition to visual signals, can report health data via an audio or vibration signal.

additional characteristics

Different companies add touch elements and convenient buttons for certain actions to their device control. The memory capacity of devices varies; on average, a bracelet-tonometer records about 200 signals, they are synchronized and this allows you to analyze changes in blood pressure over a certain time. Some models display not only the usual numbers or candles on display screens; all data can be displayed in a clear graphical form. The amount of accumulated information depends on the duration of wearing the BP measurement bracelets, and it is easier for doctors to give a more objective conclusion about the patient’s well-being.

Fitness bracelets are devices that help monitor and measure heart rate and do not have any negative effects on the body. This is a well-designed accessory with a modern design and at the same time a useful device in many respects. Many models include a distance meter (pedometer), which allows you to objectively assess the level of physical activity during the day. Other applications can easily adjust the required nutrition system based on data on calories burned.

Blood pressure bracelets can be purchased from many good pharmacies. Following fashion, you need not only to take care of the appearance of the bracelets, but also first consult with a dermatologist about wearing these devices on your hand around the clock, although manufacturers should first of all take care of their effect on the skin. In all catalogs they claim that their product is environmentally friendly and complies with the norms and standards accepted in the world and Europe, in many ways this is true, but everyone must personally make sure that nothing will harm them.

Principle of operation

These devices are based on the principle of measuring a pulse wave, which is recorded by a sensor and, through an electronic circuit according to a program, converts these signals into values of pressure units in digital, columnar or graphical form, showing blood pressure values near the heart. Based on the results of many years of practice and scientific research, the accuracy of blood pressure measurements using these devices reaches 98%.

Developers of bracelets continue to improve them in order to reduce errors and filter extraneous signals and eliminate the receipt of false signals about the state of blood pressure and the general condition of the patient. The more accurately the sensor works, the greater the confidence in the correct readings. Sensors using the properties of piezoresistive fibers take into account that when wearing bracelets on the hand, the accuracy can be affected by the tense state of the muscles, vibrations during exercise, poor fit to the surface of the hand, abrasions and other external influences.

There are many ways to do this, from stationary measurements to the use of strictly individual ones. One of the most convenient modern devices for monitoring blood pressure is a bracelet. In order for the bracelet to give correct readings, you need to know its structure, characteristics and procedure for use. A fully charged device operates without recharging for 5 days.

There are models that help assess the depth of sleep and obtain data on the level of fatigue of the wearer of the bracelet. It is not difficult to buy such devices. It’s not a matter of price, although the more expensive ones have a greater number of options, but of reliably measuring the main indicator of health - blood pressure. With such a beautiful and reliable bracelet on your hand, you can monitor your health indicators during any activity. You can receive a signal in time about overloads on the body and build an exercise program in an optimal mode.

Technologies are rapidly being introduced into the everyday life of the common man. The smartphone has become an integral attribute that allows you to constantly maintain contact with loved ones. The positive side of progress is the emergence of gadgets that allow control over the dynamic state of the human body.

One of the most popular devices is smartwatches; some models are equipped with a heart rate sensor and blood pressure detection. Such capabilities, placed on the wrist, are very important for athletes and older people.

Who needs such a device?

Diseases associated with disruption of the heart muscle or changes in blood pressure (BP) today rank first among the causes of high mortality in developed countries. Only early detection of conditions that can cause life-threatening complications can significantly increase the likelihood of timely medical care and saving lives.

Even modern automatic blood pressure monitors are quite large, which makes it difficult to monitor blood pressure levels around the clock without compromising human comfort. From this point of view, fitness trackers or smart watches that have the function of measuring blood pressure levels are more convenient. These devices have a compact size, light weight and ergonomic shape, thanks to which a person can use the watch around the clock without disturbing his usual daily routine.

Diseases associated with cardiac dysfunction require constant monitoring

In addition to the ability to count the number of steps taken, calories burned, distance traveled per day and notify about incoming calls, smartwatches are mostly protected from dust and moisture. Thanks to this, a person can use the function of dynamic control of blood pressure and heart rate during sleep or even during sports. Taking into account the above, it can be argued that a watch with the function of measuring the functioning of the cardiovascular system is suitable for both athletes and people suffering from disturbances in the level of intravascular pressure.

Manufacturers

Just a few years ago, the production of smart devices was monopolized by large brands such as Apple, Sony and Samsung. Today we can observe significant growth in this sector of the electronics market, as lesser-known brands of both American, Japanese and Chinese origin are rapidly gaining momentum.

Back in 2014, Intel decided to develop and produce smart watches capable of measuring the work of the heart muscle. As a result, the Basis line of devices appeared, which found its user due to its high accuracy of indicators, low cost and long-lasting operation on a single battery charge.

Less well-known, but nonetheless promising brands, manufacturers include the following companies:

Xiaomi;
Fitbit;
Garmin;
Polar;
Skmei;
Jawbone.
