In modern medicine, the definition of blood pressure using a Blood Pressure Machine has become widespread. There are enough varieties of Blood Pressure Machines s that allow the patient to track blood pressure independently. An automatic Blood Pressure Machine s allows you to measure pressure quickly and informatively enough. Mechanical Blood Pressure Machines s are not a thing of the past. Which Blood Pressure Machines s are best to use, in which situations? How to measure blood pressure correctly? You’ll find out about all this from this article.
Measuring Blood Pressure
In medical practice, it is quite common to resort to measuring blood pressure. This is a fairly simple and informative method of diagnosing many pathological conditions. Blood pressure should be maintained at a certain level. Excessively high blood pressure is called “hypertension.” Shallow blood pressure is called “hypotension.”
The history of accurate blood pressure measurement is not so great. The first attempts to objectively assess blood pressure levels were made at the end of the 19th century. The most well-known and widely used method introduced by N.S. Korotkov in 1905. This method is the basis of all modern devices for measuring blood pressure. The essence of the method is to put the cuff on the shoulder area and then pump it into the air cuff. The pressure created by the air in the cuff registers the arrow (or display) of the Blood Pressure Machine. At the same time, the stethoscope is installed in the elbow bend area above the projection of the shoulder artery. The cuff is inflated until the noise above the shoulder artery is recorded. Then the cuff is slowly blown off. The pressure indicator at which the first sound noise is heard corresponds to systolic pressure. That pressure indicator, when the sound tones above the artery disappear, corresponds to diastolic pressure.
What is blood pressure?
Blood pressure refers to the pressure that blood exerts on the walls of the arteries. This parameter is fundamental in assessing the quality of the circulatory system. With normal heart function, sufficient volume of circulating blood and vascular tone is maintained optimal blood pressure. In this situation, adequate perfusion of organs and tissues of the body is carried out. In hypotension, there is a decrease in the quality of perfusion of organs and tissues, leading to a decrease in the body’s adaptive abilities. Severe hypotension may indicate the development of a shock condition. In hypertension develops excessive load on the heart, blood vessels, disrupted kidneys, nervous system. Chronic hypertension significantly increases the risks of vascular complications such as stroke or myocardial infarction.
Why measure blood pressure?
Measuring blood pressure provides important information about the state of the body’s cardiovascular system. Registration of high or low blood pressure rates can correct the therapy of disease. It is difficult to imagine a visit to a therapist, especially a cardiologist, without a procedure to measure blood pressure. In several situations, such as anesthesia, the blood pressure measurement can be carried out in real-time in the intensive care unit.
Complaints arising from high blood pressure:
- Headache of varying degrees of intensity
- Tinnitus, often throbbing
- Nausea, dizziness, heartbeat, sleep disturbance
- Visual impairment is often mentioned in the flashing of “flies” in front of the eyes
- Pain in the heart area is usually not typical and different from an attack of angina
Complaints arising from low blood pressure:
- Weakness, lethargy, inhibition
- Dizziness, fainting
- Pale skin
Blood pressure devices
Blood pressure devices can record pressure levels by direct (invasive) and indirect (non-invasive) methods. With a direct method of measuring blood pressure, the needle with the sensor is inserted directly into the artery. This method in medical practice is used quite rarely, mainly in cardiac surgery. Non-invasive methods of registering pressure are the most common. A device that carries out an indirect blood pressure measurement is called a Blood Pressure Machine or sphygmomanometer. In this case, there is no need for catheterization of the vascular bed; it is enough to put on the shoulder cuff of the sphygmomanometer and measure blood pressure by the method of Korotkov automatically or manually. The accuracy of the pressure assessment is slightly inferior to the invasive method. However, the convenience and simplicity of the indirect method compensate for this error. Modern non-invasive devices for measuring blood pressure are easy to use and easy to use. If desired, the patient can assess the pressure on his own.
Sphygmomanometers, or Blood Pressure Machine s, are classified as: mechanical (manual) and automatic.
Mechanical sphygmomanometers consist of a digital scale gauge, cuffs, air supercharger, and hoses that connect them. A stethoscope will also be required to measure blood pressure. With the stethoscope, it is possible to hear pulsation in the area of the artery projection. The earliest sphygmomanometers were equipped with a glass tube containing mercury. At the moment, they have been abandoned in favor of a Blood Pressure Machine s without a mercury scale. However, until now, blood pressure is expressed in millimeters of mercury column (mm. art.
Automatic sphygmomanometers can measure blood pressure without human participation, just put on the cuff and press the “start” button. Automatic sphygmomanometers have a built-in air supercharger. They work from a built-in battery or a network. The cuffs of automatic Blood Pressure Machine s can be of two types: for the wrist and the shoulder. Blood pressure is displayed on display; along the way. The automatic Blood Pressure Machine can calculate the pulse. The latest measurement results are made in the memory of the device.
There are also semi-automatic Blood Pressure Machines s. The principle of their action is similar to automatic, with the only difference that the air filling of the cuff is carried out manually.
Pressure-measuring Blood Pressure Machines
For more than 100 years, Blood Pressure Machines s have been used to measure pressure. During this period of time, doctors of many specialties have adopted Blood Pressure Machines. Therapists, resuscitators, cardiologists use Blood Pressure Machines s to measure pressure every day in their clinical practice.
As we have already found out, modern Blood Pressure Machine s are mechanical (manual) and automatic (electronic). Semi-automatic Blood Pressure Machines s are also found, but much less frequently. Mercury Blood Pressure Machine s are not currently used due to the insecurity of their operation.
Mechanical Blood Pressure Machine
When you come to see a therapist or cardiologist, you will be determined by the pressure with the help of a mechanical Blood Pressure Machine. To do this, the doctor will put a cuff on your shoulder area and install a stethoscope in the ulnar pit area. After inflating the cuff to the desired value, the doctor will gently blow off the air, assessing the hearing pulsation of blood. The pressure in the cuff is assessed with the arrow of the gauge. This figure will correspond to the upper (systolic) pressure when the gauge evaluates the tones above the artery. When the tones above the artery disappear, the gauge readings are assessed again, so the lower (diastolic) pressure is detected.
The mechanical Blood Pressure Machine consists of:
A special rubber chamber, where the air is pumped. Outside, the cuff is pasted with a cloth and equipped with a textile clasp for fixing. In some cases, the cuff is equipped with a metal brace for the convenience of putting it on. The cuff is often schematically indicated by the rule of its use.
A supercharger with an air output valve.
It is a pear-shaped cylinder, squeezing which, in the cuff, pumped air. Equipped with a valve to release air, with it in the cuff, reduce pressure.
The pressure sensor is made in the form of an arrow and a measuring scale. Used to assess the pressure inside the cuff.
They connect the cuff, gauge, and supercharger.
The stethoscope is not part of the Blood Pressure Machine, but it is necessary to measure blood pressure by the Method Korotkov. Sometimes the stethoscope is sold, complete with a sphygmomanometer. In some models of mechanical sphygmomanometer, the head of the stethoscope is fixed to the cuff of the sphygmomanometer.
Measuring blood pressure with a mechanical Blood Pressure Machine is considered to be the most accurate and informative.
Blood Pressure Machine electronic
The electronic Blood Pressure Machine is easy to use, and the patient can use it to measure blood pressure independently. Before using such a Blood Pressure Machine, you need to check the charge of the device. An electronic Blood Pressure Machine s can run from a built-in battery, batteries directly from the power grid. Also, check the tightness of the cuff and rubber tubes. Electronic Blood Pressure Machine s to measure blood pressure is considered less accurate than mechanical. To use the electronic Blood Pressure Machine, you need to put on the cuff and press the start button. The device will independently measure blood pressure, calculate the heart rate, and keep its memory of the latest results.
The electronic Blood Pressure Machine pumps air into the cuff on its own. This is the main difference between it and the semi-automatic Blood Pressure Machine. The cost of an automatic Blood Pressure Machine is slightly higher than a semi-automatic one.
In addition to individual use, the electronic Blood Pressure Machine is used in intensive care units and during surgical interventions in the system of a comprehensive assessment of vital indicators.
The right Blood Pressure Machine
Let’s try to understand what the right Blood Pressure Machine should look like. The Blood Pressure Machine is necessary to measure blood pressure. Therefore, the correct Blood Pressure Machine should make measurements as accurately as possible. However, if you use a mechanical Blood Pressure Machine, you need to have a certain skill in measuring pressure. Also, using a mechanical Blood Pressure Machine is not always convenient in the case of measuring pressure to yourself. Ideally, a mechanical Blood Pressure Machine should be used by a doctor.
The correct automatic Blood Pressure Machine should automatically measure blood pressure. To make the measurement, just press the start button. The cuff is automatically inflated, and the pressure will also be measured automatically. The correct electronic Blood Pressure Machine has a clear display with large numbers, illumination of the display, the ability to save measurement results. Also, the correct electronic Blood Pressure Machine will calculate the heart rate, assess its rhythmicity.
However, it should be remembered that in many respects, the accuracy of blood pressure measurement depends on the patient. The cuff should be set correctly. The Blood Pressure Machine should be corrected. The patient is calm, etc.
The pressure figures themselves are not very informative. To make a diagnosis should take into account the history, complaints, laboratory tests. If the patient can independently measure blood pressure with a Blood Pressure Machine, this is good. However, the interpretation of the results should be handled by a doctor. Changes in blood pressure may indicate various cardiovascular, nervous, endocrine systems, and kidneys. The selection of drug therapy for hypertension should be carried out only by the attending physician. Self-medication in such cases is unacceptable.
Best Blood Pressure Machine
Choosing the best Blood Pressure Machine, you should be aware of several rules.
- You need to decide how often you will measure blood pressure.
- How accurate are the results you need?
- For what purpose do you measure blood pressure.
- Do you know how to use a mechanical Blood Pressure Machine?
The most preferred Blood Pressure Machine in terms of measurement accuracy is considered a mechanical Blood Pressure Machine, but its use requires some skill. The automatic Blood Pressure Machine will measure the pressure faster but less precisely. Its application does not require effort, just to press the “start” button. In any case, before buying the Blood Pressure Machine, it is necessary to check its integrity and performance. The cuff should be airtight, the display, and the device’s body; the hoses should be without flaws.
Choosing the best Blood Pressure Machine should remember that a doctor should assess blood pressure. And it is best if a doctor will make the measurements themselves. The device itself for measuring blood pressure, if it was without production flaws, will last effectively and long—the main thing to observe the rules of operation and safety.
Blood Pressure Machine on the wrist
One of the types of electronic sphygmomanometers is the Blood Pressure Machine on the wrist. This kind of sphygmomanometer has a smaller size and a smaller cuff. The pressure indicators are registered on the wrist above the radial artery. Using such a Blood Pressure Machine is more convenient, but its use has some limitations. It’s all about the accuracy of the blood pressure measurement. The error of the results in the Blood Pressure Machine on the wrist is much higher than that of Blood Pressure Machine s, which measure blood pressure in the shoulder area. In connection with this error, the use of Blood Pressure Machines s on the wrist in medical practice is quite limited. The doctor will always measure the pressure of his patient with a mechanical Blood Pressure Machine, as the accuracy of the assessment, in this case, will be higher. It is possible to use a Blood Pressure Machine on the wrist as part of the patient’s pressure assessment, but the doctor should not rely entirely on such results.
Where to buy a Blood Pressure Machine
You can buy a Blood Pressure Machine not only in the pharmacy. There are many specialty stores of medical equipment, where you can also purchase a Blood Pressure Machine. Also, a wide range of tones is presented in online stores. However, when buying a Blood Pressure Machine, you need to determine what kind you need. If you are a doctor and the Blood Pressure Machine you need to work on, it is better to take a mechanical Blood Pressure Machine. If you buy a sphygmomanometer to assess your own pressure, it is better to choose an automatic view of the sphygmomanometer. Before buying the store medical equipment, you need to make sure that the device to measure blood pressure is healthy. To do this, check the Blood Pressure Machine for defects, put it on the cuff, measure your pressure. It is better to buy a Blood Pressure Machine in a large specialty store.
The price of Blood Pressure Machine s also vary, sometimes significantly. Automatic Blood Pressure Machines s on the wrist is the most expensive. A Blood Pressure Machine s automatic with a cuff on the shoulder is also relatively expensive. Semi-automatic Blood Pressure Machines s are somewhat cheaper than fully automatic ones. Simple mechanical Blood Pressure Machines s are cheaper than all the others. The price is also affected: the material from which the device and the manufacturer are made.
How to choose a good automatic Blood Pressure Machine
To choose a good auto Blood Pressure Machine, you need:
- Purchase in a specialty store
- Ask the sales consultant about the chosen Blood Pressure Machine model in detail before buying.
- Examine the Blood Pressure Machine for flaws

How to measure blood pressure with a Blood Pressure Machine
Before you start measuring pressure, several conditions need to be met to obtain the most objective indicators.
- It is not recommended to drink alcohol, coffee, and tobacco
- Do not exercise before the procedure
- The procedure is performed in a calm atmosphere
- You need to sit down and relax
- The hand on which the Blood Pressure Machine cuff is put should not be strained
- Do not be nervous and move during the procedure, from conversations is also desirable to refrain
- You can determine the pressure on both hands for accuracy, but between procedures, you need to wait 3 minutes.
The pressure procedure itself begins with the cuff. The cuff is placed on the shoulder slightly above the elbow bend. If you have an electronic automatic Blood Pressure Machine, after the cuff is superimposed, press the “start” button, and the Blood Pressure Machine will measure the pressure itself. If you have a semi-automatic Blood Pressure Machine, you will have to inflate the cuff yourself. All other measurements will perform the device.
If you have a mechanical Blood Pressure Machine, the measurements are carried out manually. To do this, you need to install a stethoscope in the area of the ulnar pit above the projection of the shoulder artery. Inflate the cuff until it stops listening to the pulsation or until about 180-200 mmHg. After slowly blowing off the cuff, visually fixing the indicators of the gauge. After listening to the first tones of the pulsation above the artery, fix the indicators of the gauge. This is a systolic pressure figure. After the disappearance of the heard tones above the artery again fix the indicators of the gauge. It’s a diastolic pressure figure. Registration of pressure figures using a mechanical Blood Pressure Machine requires good hearing and vision and some experience of such a procedure.
Some important moments in the pressure measurement:
- At high blood pressure, the initial pressure in the cuff can exceed 200 mm. mouth. Art.
- Be sure to check the stethoscope before measuring pressure
- Check whether the cuff is properly applied, as well as the tightness of the cuff
- Don’t use the old Blood Pressure Machine
- If necessary, repeat the measurement several times
- If you use an automatic Blood Pressure Machine, check your battery before using
- Always write down and tell your doctor your blood pressure
How to measure pressure without a Blood Pressure Machine
Without the use of a Blood Pressure Machine, you can estimate the pressure indicators. Here are examples.
Subjectively, you can feel the symptoms of high or low blood pressure. So headache, shortness of breath, flashing “flies” in front of the eyes, anxiety, tense pulse, nausea can be symptoms of high blood pressure. Fatigue, weakness, fainting, weak pulse indicate low pressure.
There are also very controversial folk methods of measuring blood pressure. One of the most common and widely discussed is the pendulum method. To implement this method, it is suggested to use a ruler, thread, and ring (sometimes use a needle or nut). The essence of the method is as follows:
- The examine sits down, lays his forearm on the horizontal surface of the table
- On the inner surface of the forearm set a ruler, the beginning of the scale of the division of the line at the level of the wrist joint
- The ring is hung on a thread and brought to the ruler. It turns out something like a pendulum
- Move the ring along the line (from the wrist joint to the elbow)
- The place where the ring will move independently to the side and fluctuate, mark on the scale of the line – this is the lower pressure
- The same algorithm of actions is done, moving from the elbow to the triple joint
- The place where the ring will move independently to the side and fluctuate, note on the scale of the line – this is the top pressure
However, it should be warned that there is no real scientific justification or even information about this method. Remember, blood pressure is determined only with a special device – a sphygmomanometer or Blood Pressure Machine. Any other methods medical science does not consider. In situations where blood pressure is really critically elevated (or lowered), such anti-scientific tricks can misinform the patient and lead to undesirable complications. For this reason, the doctor always measures the patient’s blood pressure on his own with the help of a Blood Pressure Machine.
