Benefits of an automatic blood pressure monitor

Mechanical measurement method

The method of measuring blood pressure, which therapists have been using for over 100 years, was proposed in 1905 by the Russian surgeon N.S. Korotkov. The doctor puts an inflatable cuff on the patient's arm and pumps it with a rubber bulb with a pressure gauge attached to it. The doctor then slowly releases the air while listening to the heart rate with a stethoscope. By the appearance of a heartbeat, the therapist determines the systolic (upper) pressure, and by its disappearance, the diastolic (lower) pressure. This mechanical measurement method is named after Dr. Korotkov, is officially approved by the WHO and is considered the most accurate.

Mechanical tonometer
Mechanical tonometer

Doctors have been using a mechanical tonometer for over 100 years.

Disadvantage of the mechanical method: measurements must be carried out by a professional with extensive experience. It is not easy to independently measure blood pressure with a sphygmomanometer, especially for the elderly. It is necessary to correctly inflate the cuff, carefully bleed the air and hear the necessary sounds in time.

Semi-automatic measuring method

To simplify the procedure for patients, engineers have created semi-automatic blood pressure monitors. They have the same cuff and a hand pump, only the heart sounds are "listened to" not by the sensitive ear of the doctor, but by an electronic circuit. The readings are processed by the computer, the results are shown on the indicator screen.

Advantages of a semi-automatic device:

  • the patient can measure the pressure on his own;
  • a stethoscope is not needed, a person does not need good hearing;
  • no analog gauge, no sharp vision required;
  • no electric air pump, batteries will last a long time;
  • a semi-automatic device is cheaper than an automatic one.

Disadvantages of a semi-automatic tonometer:

  • the patient himself blows air into the cuff with a hand-held pear;
  • a person may exceed the pressure or unevenly bleed air - this affects the accuracy of measurements;
  • older people, especially those with limb problems, find it difficult to manipulate the pump.

The pressure is determined by the automation

To get rid of the disadvantages of semi-automatic blood pressure monitors, the designers have created a one-button device. The patient only needs to put on the cuff correctly and press the key. Electronics will inflate the cuff to a predetermined level, bleed air, detect heart sounds, measure blood pressure, and display heart rate.

The advantage of an automatic tonometer: fully automatic measurement of blood pressure and other indicators. Disadvantage: high price.

What to look for when choosing an automatic blood pressure monitor

Hand size

Before heading to the store, measure the circumference of the user's arm midway between the elbow and shoulder.

Determining hand size
Determining hand size

Surround the arm with a centimeter in the middle between the shoulder and elbow

According to this parameter, cuffs for tonometers are produced in the following basic standard sizes:

  • 18-22 mm (S) - small cuffs, suitable for children;
  • 22–32 mm (M) - Standard cuffs, fits most patients;
  • 32–45 mm (L) - large cuffs, needed for athletes or overweight people;
  • 45-52 mm (XL) - very large, required for obese people.

Choose a tonometer with a cuff of a suitable size - the manufacturer indicates its parameters in the characteristics.

If people of different sizes use the tonometer at home, look for models with replaceable cuffs, or choose a device with a universal cuff, 22–45 mm.

Fan cuff

Universal cuff fits either arm

Arrhythmia symptoms

Arrhythmia, or abnormal heart rhythm, occurs in 70% of people over 50. Skipping a beat or extraordinary contractions of the heart muscle affect the accuracy of the pressure measurement, so an automatic tonometer must be able to detect arrhythmia.

An automatic blood pressure monitor, which takes into account possible arrhythmias, monitors the patient's pulse and performs repeated measurements at moments of stable pulse. If the device detects arrhythmia, a flashing heart icon appears on the device screen.

Measurement logs and tonometer users

People with abnormal blood pressure should have regular blood pressure measurements. Usually, the attending physician requires to keep a log of measurements indicating the time of measurements and the magnitude of pressure. Choose an automatic tonometer with memory of previous measurements.

If more than one person uses the tonometer in the family, for example, an elderly couple, choose a tonometer with user switching. In this case, a separate measurement log will be available for each person.

The switch in the lower left corner changes the user

The OMROM M6 Family tonometer is equipped with a mechanical user switch. The same lever can be used to keep independent logs of measurements, for example, morning and evening.

Display and indication

Most often, elderly people, whose vision is far from ideal, become users of the tonometer. Please note that the numbers on the display are large and contrasting.

Tonometer screen

The numbers on the screen must be clearly visible

Even a fully automatic device requires correct action from the user. Additional sensors of the tonometer will help to control the position of the cuff and the immobility of the hand. If the patient has incorrectly fastened the cuff or moved in the process, the electronic circuit will show the corresponding icon on the screen and repeat the measurements.

Mains power supply

The feature of the automatic tonometer is an electric air pump that consumes energy. All automatic blood pressure monitors are battery powered. If the battery is discharged, the measurement accuracy decreases. Half of the manufactured devices contain an adapter for mains power supply.

How to choose an automatic blood pressure monitor?

All automatic blood pressure monitors use the principles laid down by Dr. Korotkov. However, the method of measuring pressure is different, it is called oscillometric. In the cuffed artery, blood pulsations occur, which cause changes in air pressure in the inflated cuff. An electronic circuit records these changes and displays the upper and lower blood pressure on the screen.

Tonometers are manufactured by companies specializing in medical equipment:

  • The Japanese company OMRON - occupies 20% of the Russian market of blood pressure monitors, the devices are very reliable and durable, but their price is 30-50% higher than for models from other manufacturers, 2000-7000 rubles.
  • The Japanese company A&D holds the patent for the oscillometric method that is used in all automatic blood pressure monitors. The company's devices occupy 20% of the Russian market, they are slightly cheaper than 1,500-5,000 rubles.
  • The Swiss company Microlife produces medical equipment for self-diagnosis. Microlife blood pressure monitors occupy about 10% of the market in Russia, they are of high quality and accurate, while their prices are significantly lower (1,800–4,000 rubles).
  • The Nissei trademark belongs to the Japanese company Nihon Seimitsu Sokki Co., Ltd. The world's first electronic pressure measuring device was manufactured by the company in 1978. In Russia, the company occupies about 4% of the market, the devices cost 2000-4000 rubles.
  • The German company Beurer, founded as a family business at the beginning of the 20th century, produces heating pads and electric blankets. Among the company's products there are also automatic blood pressure monitors (3% of the Russian market). Prices are in the range of 1000-4000 rubles.

Companies produce blood pressure monitors for shoulder (shoulder) and wrist (wrist) attachments.

The device is powered by four AA batteries, in order to save power adapter is not attached.

Wrist tonometers

Tonometers that are placed on the wrist for measurement are called wrist monitors. Unlike the brachial arteries, the pressure is measured at the radial artery, in the same place where the pulse is usually checked. Hence the second name - wrist. By design, wrist blood pressure monitors are like huge watches worn on the wrist. They do not provide power from an external source.

With age, the walls of the vessels become denser, and Korotkov's tones are less distinguishable. Therefore, it is necessary to measure pressure in people over 40 years old only on the shoulder. Manufacturers every year talk about the next "revolution" in measuring pressure on the wrist, and practice continues to show the complete inadequacy of measurements in the period of late adulthood and older.

Nevertheless, all manufacturers have models of heart rate monitors. They are compact and easy to use.

Reviews on the use of wrist tonometers

How to use the tonometer correctly

Blood pressure varies throughout the day and depends on many factors. In order for the tonometer to show the correct value, you need to prepare for the measurement.

Recommendations for preparing for pressure measurement

  1. Measure your blood pressure at the same time, for example in the morning. With long-term monitoring, a good time for the second measurement is evening. Visit the toilet before your procedure.
  2. Do not smoke, drink coffee or medications for blood pressure before taking the measurement. After running or climbing stairs, the pressure will be increased. Relax for at least 15 minutes after light physical activity and for an hour after exercising.
  3. Sit in a comfortable position and sit quietly for about five minutes. The room should be at a normal, comfortable temperature. The cold will constrict blood vessels, the pressure will rise.
  4. Attach the cuff to your non-working arm (left for right-handers) so that the edge of the cuff is 2–3 cm above the elbow joint. The cuff should fit snugly, but not tight. The cuff must not be worn over clothing.
  5. Place your hand on a table with the middle of the cuff facing your heart. When measuring, the arm should be relaxed. With tension, the pressure will rise.
  6. Turn on the automatic blood pressure monitor and wait for the results. You cannot talk during the measurement - the values ​​will be distorted.
  7. If you think the measurement should be repeated, you cannot do it right away. The deviation will be significant. Wait ten minutes and repeat the procedure. Some blood pressure monitors have an automatic mean pressure reading function. Such a device will automatically repeat the measurement after a few seconds and display the average value.

Why does the automatic blood pressure monitor show different results?

Blood pressure changes over time, so even successive measurements can give different results. In addition, user errors affect measurements.

Why does the tonometer junk

Sometimes the tonometer does not show the measurement results at all, sometimes instead of numbers, various symbols are displayed on the screen. There may be various reasons for this. Since the designs of all blood pressure monitors are different, there is no universal answer - check the instructions for using your device.

Tonometer does not work

Check the batteries and correct installation. If the batteries are discharged, the device will not turn on. Replace the batteries with fresh ones, observing the polarity.

Tonometer shows symbols instead of numbers

If symbols are shown instead of numbers on the tonometer screen, this means that measurements are being taken incorrectly. The decoding of symbols depends on the manufacturer, read the instructions for the device.

Table: examples of symbols on the screen of the OMRON tonometer

Symbol Value Actions
EE Cuff not inflated enough Change the settings to make the device pump more.
E Measurement errors:

  • the air duct is not connected;
  • the cuff is incorrectly applied;
  • clothing interferes;
  • leaking air from the cuff;
  • the patient moved while measuring.
Eliminate errors:

  • Check the connection of the cuff air duct to the device;
  • reapply the cuff;
  • remove clothing;
  • replace the cuff;
  • repeat measurements, do not move when measuring.
Battery indicator blinks The batteries are empty Replace batteries
Er Internal device error Remove the batteries from the device, wait 10-15 seconds, insert the batteries into the device. If it does not help, contact the service.

Invalid values ​​and other difficulties

Manifestation Cause Actions
The tonometer shows clearly incorrect values ​​- overestimated or underestimated
  • the cuff is incorrectly applied;
  • conversation during measurement;
  • clothing interferes with measurement.
  • reapply the cuff;
  • do not talk during the procedure;
  • take measurements on a hand without clothes.
Cuff pressure does not increase
  • the duct is not firmly inserted into the housing;
  • leaking air from the cuff.
  • check the insertion of the air duct into the tonometer body;
  • replace the cuff.
Cuff deflates too quickly Cuff does not fit snugly around the arm Apply the cuff more tightly
The device turns off during the measurement The batteries are empty Replace batteries

A tonometer is a medical device that helps you monitor your health and warn you about problems in a timely manner. The choice of this device should be approached responsibly: go past cheap Chinese crafts and fashion trends like measuring pressure in a smartphone, and take a reliable device from a well-known company. When choosing a tonometer, the patient's age and diagnoses must be taken into account. It is necessary to prepare for measuring pressure, and follow simple rules in the process. Be healthy!
