Rules for measuring blood pressure !!

Measuring blood pressure is the first thing to do if you feel unwell. The evaluation of the tonometer indicators can be carried out only if all the rules for this manipulation are observed. Timely identification of blood pressure problems is the goal of all healthcare professionals. At this initial stage, the disease can be controlled without allowing it to develop to a serious stage.

Blood pressure is the force with which the blood flow presses on the walls of blood vessels and arteries. There are two types of pressure, upper (systolic) and lower (diastolic). The normal blood pressure is 120/80 mm Hg. Art. which means ideal blood pressure. Often, individual characteristics of the body affect blood pressure, that is, from birth, a person may have a blood pressure higher or lower than normal, and at the same time he feels good.

Many factors can affect the blood pressure level, but more often it is regular an increase in blood pressure signals that diseases have appeared in the body.

Diseases affecting the increase in blood pressure:

  1. Diseases of the cardiovascular system.

  2. Disorders of the kidneys.

  3. Diseases of the endocrine system.

  4. Neurological problems, etc.

Some ailments can also lower blood pressure, along with individual predisposition and stress.

Diseases affecting lowering blood pressure:

  1. Heart failure.

  2. Vegetovascular dystonia of hypotonic type.

  3. Peptic ulcer of the duodenum and stomach in the acute stage.

  4. Internal bleeding.

  5. Depressive states.

However, it is often not possible to determine the cause of a constant decrease or increase in blood pressure. The goal of doctors is to understand this situation and improve the patient's well-being. Hypertension is much more common than hypotension and is a serious medical condition. To find out whether this disease actually exists, you need to carefully monitor your blood pressure, measure your blood pressure regularly.

In the case of a constant increase in blood pressure, the question of the development of hypertension is raised. The more often and higher the increase in blood pressure, the more advanced the stage of the disease. Hypertension is classified into 4 degrees, each of which requires its own approach to treatment.

Measuring blood pressure

Determining the level of blood pressure in a person is quite simple. There is a large selection of blood pressure monitors, the purpose of which is absolutely accurate blood pressure readings. The first thing to do for a person who constantly suffers from an increase or decrease in pressure is to purchase a good device of such a purpose so that it is convenient and as often as possible to measure blood pressure.

Hypertension can manifest itself hard for a person and cause enormous harm to the body. therefore, hypertensive patients must necessarily have a good and convenient blood pressure monitor so that the measurement of blood pressure does not cause any inconvenience. Sometimes a person can feelbad, and the first thing that comes to mind is an increase or decrease in blood pressure, in order to exclude such factors, it is necessary to determine the level of blood pressure.

Rules for measuring blood pressure:

• in 50-60 minutes before measuring blood pressure, you must not smoke and lift weights;

• coffee and caffeinated drinks must be excluded 1-2 hours before measurement;

• blood pressure must not be measured immediately after a bath or a hot bath, it takes at least an hour;

• the tonometer readings may be incorrect if the pressure is measured on a full stomach;

• a person, before taking a blood pressure measurement, should be in complete rest for 15-20 minutes;

More often, blood pressure measurement is carried out with a mechanical tonometer. The indicators of such a device are more accurate than those of its electronic counterpart.

Before proceeding, everyone needs to familiarize themselves with the rules for measuring pressure.

  1. The patient must definitely sit down at the table, all manipulations are performed only while sitting, in no case lying down. The arm to which the tonometer cuff is attached should be at heart level.

  2. Take the device out of the box and arrange all the equipment without confusing the tubes.

  3. Wrap the cuff around the arm at the forearm and secure with Velcro, not very tight, but not loose either. The assessment of the tonometer parameters cannot be adequate if the cuff was attached to clothing. Measurement should be taken with bare arm or very thin sleeve fabric is acceptable. It is considered correct to secure the cuff 2-3 cm above the elbow.

  4. Place the membrane of the stethoscope at the level of the forearm so that it fits snugly against the skin. It is in this area that the brachial artery is located. Insert stethoscope headphones into your ears.

  5. The monometer must be positioned firmly, you can fix it on the book so that you have a good view of the dial.

  6. Take a pear in your hand and screw its valve clockwise as far as it will go.

  7. With quick movements of the hand, you need to pump up the pear to inflate the cuff. You need to swing until the monometer needle shows 180 mm Hg. Art. The inflated cuff blocks a large artery and temporarily stops blood flow.

  8. Upon reaching the indicator - 180, it is necessary to slowly open the pear valve and release the air. At this time, you need to carefully monitor the numbers of the monometer.

  9. When deflating, it is necessary to listen to the blows with a stethoscope, the first blow means the systolic pressure indicator. On which number the first blow is recorded, that means the upper blood pressure.

  10. After finding out the first digit of blood pressure, you need to further monitor the monometer. As soon as complete silence and the absence of shocks and noises are recorded in the headphones of the stethoscope, it is necessary to remember the number of the monometer. This will be the indicator of the lower pressure.

If, for some reason, one of the indicators is missing, you can pump up 1 timecuff, you cannot pump more than 1 time, otherwise the tonometer readings will be incorrect.

The purpose of measuring blood pressure is to find out the level of blood pressure, therefore, for the accuracy of the readings, the measuring manipulations must be repeated 10-15 minutes after the first procedure.

Regular blood pressure measurements will reveal the disease at the very beginning of its development. Sometimes high blood pressure is recorded for the first time, and the person is confused and does not know what to do. A single increase in blood pressure does not mean that hypertension has occurred, the pressure can suddenly rise for several reasons.


  1. Emotional overloads the day before.

  2. Excessive physical activity.

  3. Eating large amounts of salt and fatty foods.

  4. Large body weight.

  5. Drinking alcohol.

  6. Frequent smoking.

  7. Hereditary factor.

  8. Older age.

  9. Diabetes mellitus and other diseases.

Only a doctor is able to find out the exact cause of an increase in blood pressure, therefore, with repeated increases in blood pressure, you should consult a doctor. Hypertension manifests itself in this way, therefore it is impossible to ignore this symptom of it.

Signs of high blood pressure:

• headache, often pulsating in the occiput;

• nausea, vomiting;

• pain in the region of the heart;

• lack of air;

• insomnia;

• feeling of anxiety;

• impaired speech and coordination;

• convulsions;

• fainting.

High blood pressure values ​​over 180/110 are very dangerous ... In this condition, serious complications can develop, leading to stroke, heart attack, and even death. When taking antihypertensive drugs, one goal is pursued - lowering blood pressure. But medication, chosen independently, does not always help, you need to take medications prescribed by a doctor, this will reduce the risk of complications and safely bring down the pressure. Hypertension requires special attention and blood pressure control, as well as regular medication.

Personally, I coped with pressure with the help of a nutraceutical, which not only stabilizes blood pressure, but also cleans blood vessels without side effects. For those interested, here's a link to the article.
