Normal blood pressure in an adult 30 years old. Norm of arterial pressure

Violation of the norm of blood pressure worsens the patient's condition, and in some cases completely chains him to a hospital bed. It will be useful for the adult population to know what a person's "healthy pressure" should be. The age limits for this indicator are detailed below.

First you need to clarify that the norm of blood pressure primarily depends on the age of the patient (it is conditionally noted: child-adolescent-adult). His gender is also taken into account. Trying to figure out what pressure is normal for a person, you need to take into account both of these factors.

Norms in adults

If we talk about adult representatives of the stronger sex, then for them the optimal pressure limits are 123/76-129/81 mm Hg. Art. Such indicators are relevant at the age of 20 to 45 years.

For women, the following indicators are considered normal pressure at the age of 20 years: 120/75 mm Hg. Art. These figures are relevant even in 30 years. As for the fair sex at 40 and 50 years old, these figures change and are as follows - 127/78 mm Hg. Art.

The norm in children

In general, there is no "children's limit" according to the indications of blood pressure. In babies, pressure is usually measured only if there are any health problems. They are subject to established standards.

As a rule, by the age of 1 year, the minimum / maximum lower blood pressure should fluctuate between 40-50 / 50-74 mm Hg. Art. And the minimum / maximum upper - 60-90 / 96-112 mm Hg. Art. Further, with age, these figures gradually increase. By the age of 12-15, the lower one is in the range of 70/80-86 mm Hg. And the top one is 110/126-136 mm Hg.

Normal blood pressure in teenagers

For adolescents (from 16 years of age), the exact norm of blood pressure has already been established. It is 100-120 / 70-80 mm Hg. Art. If parents notice a violation of the lower or upper limits, then the child must be shown to a specialist. Most likely, he will be assigned full examination which will allow to determine the causes of negative changes.

Table of normal pressure in humans

The table below of the norm of pressure in a person by age is filled with indicators characteristic of absolutely healthy people. If, when measuring blood pressure, the patient notices deviations from the indicated figures, then it is worth seeking the advice of a specialist.

What diseases can high or low blood pressure indicate?

Of course, blood pressure does not rise and fall just like that. There are certain reasons for this. They must be correctly identified in order to select the appropriate therapy for the patient. The reasons for the increase and decrease in pressure are fundamentally different.

High blood pressure is also called "hypertension". It occurs in two types. The first type is hypertonic disease. It is a chronic high blood pressure. To this day, even the most qualified specialists cannot explain its causes. The second type is arterial hypertension. With such a problem, a periodic increase in blood pressure is observed.

These changes occur for the following reasons:

• stress and frequent emotional experiences;
• improper unbalanced diet (especially - a large number of salty and fatty foods in the diet);
• bad habits(smoking, addiction to alcoholic beverages);
• flaw physical activity in everyday life;
• excess weight.

The pressure can “jump” sharply after drinking coffee or an alcoholic drink, smoking a cigarette, taking some medicines, sports training or bath procedures. For the fair sex, this problem often occurs during menopause.

In some cases, high blood pressure is a symptom of a dangerous disease.

For example, it can rise when:

1. diabetes mellitus.
2. Serious kidney disease.
3. Heart defects.
4. Problems in the thyroid gland.

Low blood pressure is called hypotension.

The drop in blood pressure also has its reasons. Among them are the following:

• infections with severe course(for example, sepsis);
• allergy;
• ailments of the gastrointestinal tract;
• diseases of the heart and blood vessels;
• taking antidepressants and / or diuretics;
• significant blood loss
• diseases of the endocrine system;
• dehydration of the body;
• strict deficient diet folic acid and some vitamins;
• work in hazardous conditions (underground, at high humidity or temperature, etc.).

In addition, blood pressure often decreases in pregnant women. If it falls slightly, then it is not dangerous for the mother and fetus. A sharp change in position, for example, from lying to sitting, can lead to the changes discussed.

How to lower blood pressure?

If the pressure in a man or woman turned out to be very high, then you should immediately call an ambulance. While the doctors get to the place, you will need to seat the patient on the sofa and put a pillow under his head. The patient is stripped of clothing that constricts chest, legs are wrapped. You can apply a warm heating pad to the calf muscles.

To prevent the patient from being nervous, it is worth giving him any sedative. If in the chest area he has pain, it is important for him to take a nitroglycerin tablet or take 5-6 pieces of glycine under the tongue.

If lowering blood pressure does not require urgency, then you can start improving your condition gradually. To begin with, exclude strong tea, coffee, alcoholic beverages, smoked meats, very salty and fatty foods from the diet. If possible, salt should be removed from the diet.

If life is full of unrest, then special efforts should be made to normalize your emotional state. You can take natural sedatives. For example, tincture of lemon balm, valerian, peony and others like that.

You should take care of regular physical activity and start getting rid of excess weight. The main thing is not to use strict diets and exhausting workouts.

Of the drugs for lowering pressure, Dibazol, Phentolamine, Anaprilin, Pentamine and other similar ones are used. Their selection and determination of dosage should be handled exclusively by the attending physician.

How to raise the pressure at home?

In order not to suffer from drops in blood pressure and, especially from its decrease, it is worthwhile to correctly draw up your schedule of rest and wakefulness. Hypotonic patients need to sleep at least 9-10 hours. It is advisable to rest also during the daytime.

Should be a daily ritual for the patient light gymnastics and cold and hot shower. You need to eat at reduced pressure often, but in small portions. The diet should be healthy and balanced.

Hypotension must be well lit workplace. It is also required to regularly ventilate the room.

Concerning folk remedies, then with hypotension, you can drink tincture of Eleutherococcus or ginseng. 32-33 drops per serving. A cup of strong green tea or coffee will also help to quickly raise the pressure.

If the pressure began to drop sharply, and the patient felt unwell, then a pinch of salt should be put on the tongue. This will quickly alleviate the condition. You can replace salt with canned cucumber or salted nuts. Helps and is applied to the heels of a piece of natural fabric, abundantly moistened with apple cider vinegar. This procedure removes headache resulting from a fall in blood pressure.

Increases pressure and hot hibiscus tea. The main thing is not to forget that when cold, such a red drink has the opposite effect. Tea must be freshly brewed. It is allowed to add granulated sugar to it.

If it was at hand essential oil clove or jasmine, you can drop it on a handkerchief and breathe in a pleasant aroma for a couple of minutes. A piece of quality dark chocolate and ginger tea will also help to raise the pressure. Ginger root also strengthens the vessels of the brain and heart.

Of the drugs for the purpose under discussion, Citramon, Askofen, Norepinephrine, Mezaton and other similar ones are used. It is allowed to apply ascorbic acid which increases the elasticity of blood vessels.

How to measure pressure correctly?

A special device for measuring blood pressure is always fixed in the upper part of the forearm. To determine the "suitable" hand, you need to measure the discussed indicator on both limbs with an interval of a couple of minutes. The procedure is repeated 3-4 times. The results are entered into a table. The hand on which more will be fixed high values, will be used for blood pressure measurements in the future.

Most often today, measurements are carried out with an electronic and mechanical tonometer. The process scheme will depend on the selected device.

If an electronic device is used, then it is necessary:

1. Raise the sleeve and put on a special cuff of the tonometer.
2. Place your hand on the table at heart level and press the device button.
3. Wait for the results on the instrument screen.
4. Repeat the procedure after 6-7 minutes to calculate the average value.

If a mechanical tonometer is chosen, you need:

1. Relax, warm up if needed.
2. Sit with support on the back of the sofa, relax your legs and wrists.
3. Lay your hand on the table approximately at the level of the heart, put on a special cuff on it. Between the last and forearm should pass freely forefinger. The lower edge of the cuff is located 2.5 cm above the bend of the elbow.
4. Place the phonendoscope in the cubital fossa in the place where the pulse is clearly felt, and fix it with your finger.
5. Tighten the screw on the side of the "pear" and pump air into the cuff until the tonometer needle shows a value of 210.
6. Release the "pear" and slightly open its side valve counterclockwise.
7. Listen and follow the tonometer scale until the first beats appear. The number on which they were heard will become an indicator of the upper pressure. And the indicator at which the last distinguishable sound will be heard will demonstrate the lower pressure.

Blood pressure is a vital indicator of performance of cardio-vascular system, by which one can judge the state of the body as a whole. Deviations from the physiological norm signal significant health problems. What is the opinion of doctors about the limits of indicators blood pressure?

How is BP formed?

The blood in the vessels has a mechanical effect on their walls. Purely technically, there is always pressure in the arteries and veins. But when measuring it with a tonometer, other points are also important.

When the heart muscle contracts, blood is ejected from the ventricles into the vessels. This impulse creates the so-called "upper", or systolic pressure. Then the blood is distributed through the vessels, and the minimum level of their filling, at which the heart beat is heard in the phonendoscope, gives the “lower”, or diastolic indicator. This is how the result is formed - a figure that reflects the state of the body at the moment.

Normal indicators - what should they be?

In the medical environment, there are disputes about which indicators to focus on in measuring pressure. Blood pressure norms in adults were repeatedly compiled. The table shows what numbers cardiologists and therapists used in the USSR period.

The systolic pressure indicator was calculated by the formula:

109 + (0.5 x age) + (0.1 x weight),

and the diastolic level is like this:

63 + (0.1 x age) + (0.15 x weight).

The lower limit of normal systolic pressure was considered to be 110 mm Hg. Art., top - 140 mm. All indicators that were outside these limits were taken as pathology. Similarly, the lower limit was taken equal to 60 mm Hg. Art., top - 90 mm. Collecting these numbers together, we get a range of norm indicators from 110/60 to 140/90. Many therapists and cardiologists of the old school are still guided by this in their medical practice.

Modern views on blood pressure indicators

A little later, based on numerous studies, other norms for blood pressure in adults were derived. The table used in our time was compiled by WHO in 1999. Based on it, the boundaries of the norm for systolic pressure are in the range from 110 to 130 mm Hg. Art., diastolic - 65-80 mm. These figures relate primarily to patients under 40 years of age.

Today, there is no consensus among doctors as to which indicators are considered normal and which are pathologies. During the examination, they are guided by what pressure is normal, “comfortable” for a particular patient, and record this information from his own words. In the future, in the diagnosis and treatment proceed from this indicator. Numbers below 110/60 and above 140/90 will still be considered signs of pathological changes.

Working pressure - what is it?

This expression can be heard in everyday life. The concept of “working” pressure refers to such indicators at which a person feels comfortable, despite the fact that one or both of them - systolic and diastolic - are significantly increased or decreased. In general, such an attitude towards oneself reflects only a desire to ignore the existing problem.

Cardiologists have no concept of "working" pressure of the patient. Values ​​above 140/90 in middle-aged individuals are classified as hypertension. The justification may be that with age, accumulations of cholesterol are deposited on the walls of blood vessels, narrowing their lumen. There is no clinically serious deterioration, but the risk of developing pathology increases significantly.

Opinions of foreign scientists

In the countries of the post-Soviet space, on the one hand, and in America and Canada, on the other, different approaches have been adopted to determine the norm of blood pressure in adults. The table shows how the patient's condition is classified depending on its indicators.

Blood pressure at the level of 130/90 can be considered prehypertension, that is, with pathology. The level of systolic indicators of 110-125 mm Hg, and diastolic - less than 80, is called in the West "a state of rest of the heart." In our country, the pressure of 130/90 will be considered the norm for physically developed men who are actively involved in sports, or people over 40 years old.

In Western Europe, the approach to the state of the cardiovascular system is similar, but in the scientific literature you can find some data similar to post-Soviet standards. There is a peculiar look at the norms of blood pressure in adults: the table contains terms that are unusual for us - “low normal”, “normal” and “high normal”. The standard is 120/80.

Age changes

The older a person becomes, the more serious changes undergo his blood vessels and heart muscle. stress, malnutrition, hereditary predisposition - all this affects the state of health. People with a diagnosed pathology are recommended to measure their blood pressure daily. It is better if the indicators are recorded in a special table. There you can also enter data after measuring the pulse.

With age, the normal blood pressure in adults gradually changes. The table and the pulse together provide objective information about changes in the state of the vessels. If the numbers at some point exceeded the patient's usual norm, this is not a reason for panic - an increase of 10 mm Hg. Art. considered acceptable after physical exertion, in a state of fatigue, after a long day at work. But a stable, long-term deviation is a sign of a developing pathology.

Should blood pressure increase with age?

Due to vascular changes that occur due to a decrease in arterial tone and cholesterol deposits on the walls, as well as changes in myocardial function, the age norm of blood pressure in adults is corrected (table).

In women 40 years old average equal to 127/80, in men it is slightly higher - 129/81. This is due to the fact that the representatives of the stronger sex, as a rule, withstand great physical exertion, and their body weight is greater than that of women, which contributes to an increase in pressure.

Dynamics of indicators after 50 years

Blood pressure is also affected by the levels of various hormones, especially steroids. Their content in the blood is unstable, and over the years, during the restructuring of the body, an increasing imbalance begins to be observed. This affects and on the fullness of blood vessels. The average rate of blood pressure in women aged 50 shifts upward and becomes equal to 137/84, and in men of the same age - 135/83. These are the numbers above which the indicators at rest should not rise.

What other factors increase blood pressure in adults? The table (in women after 50 years of age, the risk of developing hypertension is higher, since hormonal changes, the so-called menopause, begin to affect at this age), of course, cannot indicate all of them. The stresses they endured for the body are also important - pregnancy and childbirth (if they were). The statistical probability of developing arterial hypertension in a woman over 50 years of age is higher than in a similar man due to the difference in the aging process.

Indicators after 60 years

The trend established in previous years is maintained in the future. The rate of blood pressure in adults continues to increase (table). In women after 60 years, the average value is 144/85, in men - 142/85. The weaker sex is somewhat ahead in terms of growth rates (due to the same hormonal changes).

After 60 years, normal blood pressure physiologically exceeds the standard values ​​of 140/90, but this is not the basis for the diagnosis of arterial hypertension. Practitioners are largely guided by the health status of elderly patients and their complaints. In addition to measuring blood pressure, a cardiogram is used to monitor the state of the cardiovascular system, on which pathologies are much more pronounced than in pressure indicators.

Associated pathologies

In addition to age, a systematic increase in pressure provokes metabolic disorders, kidney disease, bad habits, etc. Smoking provokes narrowing of small vessels, which in the long term causes a decrease in the lumen of large arteries and, as a result, hypertension. When the kidney function is impaired, the hormone aldosterone is produced, which also leads to an increase in blood pressure. The risk of hypertension is in diabetics, whose vessels are particularly prone to deposits on inner walls. Timely detection and prevention of major diseases will keep the pressure normal and lead an active life.

Causes of hypotension

In addition to the increase, many people at a young and older age have a decrease in pressure. If this is a stable indicator, then there is practically no reason for concern. Physiologically low blood pressure can be in miniature girls or in young people with asthenic complexion. This does not affect performance.

If a decrease in pressure occurs suddenly and leads to a deterioration in the condition, then this may indicate heart failure, vegetative-vascular dystonia, rhythm disturbances, and even internal bleeding. With such symptoms, it is urgent to undergo a complete examination.

How to track performance?

It is best to have your own blood pressure monitor at home and master the technique of measuring blood pressure. This is a simple procedure and anyone can learn it. The data obtained should be entered in a diary or table. In the same place, you can briefly make notes about your well-being, pulse rate, physical activity.

Often arterial hypertension does not manifest itself outward signs until something provokes a crisis - a sharp increase in blood pressure. This condition has many life-threatening consequences, such as a hemorrhagic stroke or heart attack. It is advisable to make it a habit after 40-45 years to regularly measure pressure. This will help to significantly reduce the risk of developing hypertension.

Human health is the main, priceless gift that needs to be protected and appreciated. Over the years, it gradually worsens, and the condition of a person at the age of 30 is already significantly different from the data of 5 years ago. The norm for a person’s pressure is determined by gender and age characteristics. Of particular note is the pressure at the age of 30, the deviation of which from the norm can signal the presence of various diseases in the body. That is why doctors recommend systematically measuring the pressure in a 30-year-old person and comparing it with normal standards. In particular, in women, such observation allows not only to maintain good health, but also to prevent premature fading.

[—ATOC—]
[—TAG:h2—]

A person is interested in what blood pressure is and how it should be in certain age usually when deterioration in well-being begins to appear, associated with deviations from the norm. At its core, blood pressure is determined by the ratio of the volume of blood that the heart ejects every minute, and the width of the vessel. In this case, the blood exerts systolic pressure on the blood vessels. In the metrics, it appears first (top). When the heart is relaxed, another pressure arises in the vessels - diastolic or lower pressure.

These indicators are measured in millimeters of mercury, and look like this: 120/80 mm Hg. Art. From this data the pulse pressure can be calculated. To do this, subtract the lower number from the upper number.

How to measure

Finding out what pressure is easy with the help of a special device - a tonometer. The kit includes:

• cuff,
• cuff air supply device
• manometer, which directly measures the air pressure in the cuff.
• Stethophonendoscope (stethoscope) or reading electronic device.

In our country, mechanical and electronic blood pressure monitor. When measuring with a mechanical device, a person needs to listen intently to the sound from a stethoscope in order to timely determine the boundary impact. For electronic models, it is not necessary to use such a listening tube.

Measurement Rules

A modern woman should have an idea of ​​​​how to correctly determine blood pressure in order to get an accurate and realistic result. Normal pressure in an adult is measured in a state of complete rest. Otherwise, the indicators will display significant failures in pressure, which will be false.

In order for the arterial current to be determined exactly, you need to follow these rules:

• At the age of 35, during the day, all the physiological parameters of the body can change noticeably, so the pressure is measured systematically, at the same time,
• Before measuring, you need to rest calmly for a few minutes, since the pressure after exercise increases greatly,
• An hour before this, you can not smoke, drink coffee, strong tea,
• Not measured with a strong urge to urinate,
• The cuff should be at the woman's heart level.
• During the measurement, silence and silence must be maintained.

Normal pressure in an adult is considered when the indicators for several days are consistently the same and meet health standards.

Norms according to the table

In medicine, it is clearly stated what normal pressure a person should have at a particular age. There is a special table for checking. So, according to her data, up to 20 years of age, blood pressure should be in the range from 110/70 to 120/80. Normal blood pressure at 30 is between 120/70 and 130/80. In adulthood, the normal pressure of a person becomes higher - 140 to 90. And in the elderly, it can reach a rate of about 150 to 90 mm Hg. Art.

But in practice, these indicators are relative. Sometimes normal pressure in an adult (by medical standards) causes a noticeable deterioration in well-being. In this case, the norm should be determined by the person, depending on his personal physiology. So, it happens that a 30-year-old girl feels good only at low rates, which means that it is considered her working pressure.

Over the years, people may develop hypertension or hypotension - an increase and decrease in blood pressure, respectively.

Causes of hypertension

Ideally, the norm of pressure in a person should be maintained in all years. But in connection with the lifestyle of modern people, maintaining health is not so easy. In particular, women in their thirties often develop hypertension. An increase in blood pressure does not occur empty place. Typical reasons can be:

• Overweight, obesity
• Sedentary lifestyle,
• Having bad habits
• thyroid problems,
• Inflammatory diseases of the kidneys
• Constant stress, sleep disturbance.

Causes of hypotension

It is considered normal when a girl feels weak, gets tired quickly. But usually this is not a manifestation of the female essence, but the consequences low pressure. Hypotension by the age of 30 can develop due to:

• Vegetovascular dystonia,
• heart disease,
• Diseases of the gastrointestinal tract,
• stomach ulcers,
• Stress, overwork, lack of sleep,
• The presence of inflammatory processes in the body.

Eliminating these causes will normalize blood pressure and not waste your young age during regular visits to doctors.

pressure in pregnancy

In a young pregnant woman, pressure should always be monitored. With a favorable course of pregnancy at the age of thirty, up to the sixth month, there should be no deviations from the usual norm. In the third trimester, the normal limit increases. But the increase should not be more than 10 mm Hg. Art. If this number is much higher, then the woman in position is urgently sent for additional examinations and tests, up to hospitalization. The appearance of attacks of hypertension during pregnancy can be a signal of various problems, in particular, the development of preeclampsia, kidney damage, and the appearance of seizures.

But in any case, to determine which blood pressure is suitable for a person and which is not, the doctor should, based on the readings of the tonometer and general analysis the patient's health status.

Blood pressure is one of the main physiological functions, the normal value of which is very important for healthy condition person. Human pressure - the norm for age - naturally changes during the day and depending on various environmental phenomena.

It is quite normal that with age, the indicators rise, then around the age of 60 for a man and 70 years for a woman, they again decrease slightly. Despite this, the values ​​should always be in a healthy range. Unfortunately, due to the current way of life, these boundaries are rarely maintained.

Blood pressure in a person is the force with which blood “presses” on the vascular walls where it flows. It is created under the action of the heart as a "blood pump" and is associated with the structure and functions of blood circulation and is different in different parts blood flow. The term blood pressure refers to the pressure in large arteries. Blood pressure in large vessels tends to change with time - the highest values ​​are recorded in the pushing phase of cardiac action (systolic), and the lowest - in the filling phase of the heart ventricles (diastolic).

What blood pressure is considered normal

There is no exact answer to the question of what pressure is considered normal - healthy indicators are individual for each person. Therefore, the average values ​​were calculated:

• numbers 120/80 - evidence that blood pressure is normal;
• low - these are values ​​​​below 100/65;
• high - above 129/90.

Normal blood pressure in adults - table:

Norm of pressure in children:

• infancy - approximately 80/45;
• older children are about 110/70.

AT adolescence(up to 18 years of age) the minimum normal pressure averages 120/70; in boys, systolic pressure is about 10 mm Hg. higher than girls. Ideal blood pressure in a teenager is up to 125/70.

Sometimes in adolescents, values ​​\u200b\u200bmore than 140/90 are recorded (when measured repeatedly, at least twice); these indicators may indicate the presence of hypertension, which should be monitored and, if necessary, treated. In adolescents under 18 years of age, the presence of hypertension increases the risk of heart and vascular diseases (without prevention) by 3-4 times until the age of 50 years.

BP values ​​indicate low blood pressure in the adolescent population: for girls - less than 100/60, for boys - less than 100/70.

During the day, changes in pressure occur:

• the lowest readings are usually recorded in the morning, around 3 am;
• the highest values ​​are around 8:00-11:00, then around 16:00-18:00.

BP can rise or fall as a result of exposure to the weather, physical exertion, stress, fatigue, temperature (body and environment), sleep quality, drinking regime and even different positions of the body. Therefore, with orthostatic hypotension, it is necessary to measure values ​​​​in different positions.

High BP:

• adults 18 years and older - from 140/90 - these indicators are measured several times in a row;
• babies - over 85/50;
• older children - above 120/80;
• diabetic patients - above 130/80;
• people with kidney pathologies - above 120/80.

Low BP:

• adult men - below 100/60;
• adult women are below 100/70.

Blood pressure - the norm by age

Blood pressure (normal by age) to a certain extent depends on gender. The upper (systolic) and lower (diastolic) readings below are approximate. The minimum and maximum blood pressure can vary not only at different ages, but also depending on time and what a person does. Important factor- this is a way of life, sometimes for a particular person, seemingly high or low rates may be the norm.

BP table by age for women:

Blood pressure norm by age for men - table

Systolic BP:

Diastolic BP:

What should be normal blood pressure in pregnant women? Pressure rate- 135/85, ideally around 120/80. Mild hypertension is indicated by a reading of 140/90, with the lower (diastolic) value more important than the upper (systolic) value. Severe hypertension at this time - pressure 160/110. But why do some pregnant women have increased blood pressure if they have not previously encountered a similar problem? Experts believe that the placenta is to blame. It releases a substance into the blood that can cause vasoconstriction. Narrow blood vessels can not only retain water in the body, but, above all, increase blood pressure. However, it is often difficult to determine what is the normal pressure of a pregnant woman, due to fluctuations in indicators. Standard values ​​are taken as a basis along with factors that influence them (body weight, lifestyle…).

How to measure blood pressure correctly

AD is written as 2 numbers separated by a slash. 1st value - systolic, 2nd - diastolic. In order to identify deviations or normal blood pressure readings it is important to measure it correctly.

1. 1. Use only accurate and reliable blood pressure monitor

Without the right device, you will not get reliable results. Therefore, a good tonometer is the basis.

1. 1. Always measure at the same time

Sit down and stop thinking about worries, you should be completely at ease. From the measurement process, make a small ritual that you carry out in the morning and in the evening - always at the same time of day.

1. 1. Put on the blood pressure cuff

Place the cuff directly on the skin, always choose the width according to the circumference of the arm - a narrow or too wide cuff will greatly affect the measurement results. Measure the circumference of your arm 3 cm above the elbow.

1. 1. Relax your arm and check your sleeves

Keep the arm that is wearing the cuff free, do not move it. At the same time, make sure that the sleeve does not compress the hand. Don't forget to breathe. Holding the breath distorts the results.

- Place your hand on the table at a regular blood pressure monitor.

- For an automatic blood pressure monitor (on the wrist), the wrist should be at the level of the heart.

1. 1. Wait 3 minutes and repeat the measurement

Leave the cuff on and wait about 3 minutes. Then take measurements again.

1. Record the average of two measurements

Record the values ​​shown scale: systole (upper) and diastole (lower) from each measurement. Their average will be the result.

Measurement of blood pressure can be carried out using invasive methods. These methods produce the most accurate results, but the patient is more burdened by the need to place the sensor directly into the bloodstream. This method is used, in particular, to determine the pressure in the lungs or, if necessary, repeat measurements. In such cases, it is impossible to apply non-invasive methods due to the deformation of arterial memory and the associated change in pressure in the arteries.

Deviation from the norm probable causes

Blood pressure fluctuations are just as dangerous as high pressure, some experts consider unstable abnormalities to be even worse. Vessels undergo strong changes and influences, therefore blood clots are more easily torn away from the vascular walls and cause thrombosis, embolism or increased heart pressure therefore increase the risk of heart and vascular disease. A person suffering from fluctuations in blood pressure should regularly visit a doctor and follow all his advice, take medications and maintain a proper lifestyle.

Most common causes upward and downward pressure fluctuations include:

• age (depending on age, normal indicators also increase);
• obesity;
• smoking;
• diabetes;
• hyperlipidemia (usually due to a poor lifestyle).

The mechanism for the development of fluctuations to the higher side:

• increase in stroke volume;
• increase in peripheral resistance;
• a combination of both factors.

Reasons for an increase in stroke volume:

• increase in heart rate (sympathetic activity, response to catecholamine exposure - for example, hyperfunction thyroid gland);
• increase in the amount of extracellular fluid (excessive fluid intake, kidney disease).

Causes of increased peripheral resistance:

• increased sympathetic activity and vascular reactivity;
• increased blood viscosity;
• high impulse volume;
• some autoregulatory mechanisms.

Causes of downward swings that also apply to the development of hypotension:

• dehydration, blood loss, diarrhea, burns, adrenal insufficiency - factors that reduce the volume of blood in the vascular system;
• pathological changes and heart disease - myocardial infarction and inflammatory processes;
• neurological disorders - Parkinson's disease, inflammation of the nerves;
• fluctuations can occur with increased physical and psychological stress, stress;
• sudden change in body position from lying down to standing;
• a low value can cause the use of certain drugs - diuretics, sedatives, antihypertensive drugs.

High blood pressure symptoms

Initially high rate AD may remain asymptomatic. With an increase in the usual (normal) value of more than 140/90, the most common symptoms are as follows:

• headache - especially in the forehead and neck;
• increased heart rate;
• acceleration of the heartbeat;
• excessive sweating;
• ophthalmic disorders (visual disturbances);
• noise in ears;
• fatigue;
• insomnia;
• nasal hemorrhage;
• dizziness;
• disturbances of consciousness;
• ankles;
• deterioration in breathing.

Some of these symptoms for a person are not suspicious, because. often signify age-related disorders. Therefore, hypertension is often diagnosed incidentally.

Malignant hypertension is a condition in which the lower and upper bounds– even up to 250/130 or more. Dangerous values ​​can persist for several days, hours, or only a few minutes; pressure with such indicators increases the risk of damage to blood vessels in the kidneys, retina or brain. Without treatment, it can lead to death. In such cases, along with standard studies (ultrasound, pressure measurement), an MRI should be done - this study will help determine the choice of the appropriate treatment method.

Pulse pressure

Pulse pressure (PP) is the difference between upper and lower blood pressure. What is its normal value? A healthy indicator is about 50. From the measured values, the pulse can be calculated (table of pressure values ​​​​by age - see above). A high PP is a greater risk for the patient.

A condition in which an elevated heart rate (PP) is considered a predictor of vascular morbidity, heart disease, and mortality. Parameters established by 24-hour ambulatory BP monitoring, compared with random parameters, correlate more closely with target organs.

Pulse pressure in men is higher than the same pressure in women (53.4 ± 6.2 versus 45.5 ± 4.5, P< 0,01). В течение дня значение ПД показывает минимальную изменчивость. Значение пульса у молодых мужчин и женщин зависит от систолического, а не от диастолического АД (коэффициент корреляции импульсного и систолического давления: r = 0,62 для мужчин, r = 0,59 для женщин).

PD above 50 mm Hg. - increased. The most common reasons for an increase are:

• heart diseases;
• heart failure;
• atherosclerosis.

An increase in values ​​is a common occurrence during pregnancy. This is due to the "restructuring" of the organs and the lack of iron in the body. A common factor is a dysfunction of the thyroid gland.

PD below 30 mmHg - low (critical value - below 20). Common causes of the condition:

• anemia;
• stenosis of the heart valve.

Any deviation from the normal indicator is unfavorable for health. Pulse (beats per minute), pressure in case of suspicion of instability should be constantly monitored. If left untreated, various complications can develop. Despite the fact that we are talking about the lengthy process Negative consequences can be very serious and even life-threatening! Therefore, timely diagnosis of the problem and the introduction of appropriate treatment are important.

The norm of blood pressure is an individual indicator that depends on many factors (genetics, physique, pregnancy). However, in medicine there is an approximate norm. Deviations from it allow the doctor to identify hidden diseases organism. About what is the norm of blood pressure and what to do in case of deviation from it, read in this article.

What is blood pressure?

This is an indicator of the force that expands the walls of blood vessels. Strength depends on the efficiency of the human heart. The indicator is compared with the norm for its age. Deviations from it by 30-40 mm Hg. st indicates diseases of the endocrine, cardiovascular and nervous systems.

The blood pressure value is divided into two parameters - upper and lower. The upper parameter is systolic pressure, which shows the pressure in the arteries at the time of the heart beat. The lower parameter is diastolic blood pressure. Shows the pressure in the arteries at the time of relaxation of the heart muscle.

Normal blood pressure by age

Pressure is measured only at rest, since physical and emotional stress significantly affect the performance of the blood pressure meter (tonometer). With moderate physical exertion, the indicator rises to 20 mm Hg. Art. Its increase is explained by the involvement in the work of a number of muscles that also need blood. The norm of blood pressure for all ages varies from 91 to 139 upper and from 61 to 89 lower.

The ideal blood pressure is 120/80 mm Hg. Art.

Pressure in children and adolescents

Blood pressure in children and adolescents is lower than in adults. For example, an infant has increased vascular elasticity. The lumen for blood circulation is wider, and the number of capillaries is greater. But with the development of the child's body blood pressure increases.

From birth to age 5, boys and girls have approximately the same blood pressure. For the next 4 years (from 5 to 9), boys notice a slight increase in pressure - by 5-10 units. Having reached the values ​​of 110-120/60-70, it will be maintained at this level, regardless of age in adolescence.

The norm of arterial pressure is determined by the formulas:

• Systolic upper blood pressure is determined by the formula: for children under one year old: 76+2n, where n is the infant's age in months. For example, for a three-month-old child, the norm of upper blood pressure is 76 + (2*3) = 82 Hg. Art.;
• For children older than 1 year, the norm of upper blood pressure is calculated by the formula: 90 + 2n (n is the number of years). For example, for a three-year-old child, the norm of blood pressure is: 90 + 2 * 3 = 96 Hg. mm;
• Lower blood pressure for children under one year old is calculated as follows: from ⅔ to ⅓ of the maximum upper blood pressure;
• The lower parameter formula for children older than one year is 60 + n (where n is the number of years).

Normal blood pressure in children and adolescents:

pressure in adults

Blood pressure norms for different ages:

If young man pressure of 100/70 mm Hg is the norm, then for the elderly it would indicate serious illness. And, conversely, if for an elderly person 150/90 is considered the norm, then for young people such an indicator of blood pressure would indicate bad job cardiovascular, endocrine or renal failure.

pressure in pregnancy

In 90 percent of cases, an examination of a pregnant woman by a gynecologist begins with a measurement of blood pressure. This is a standard procedure that allows you to control the work of the cardiovascular system. From the beginning of pregnancy, a woman's body undergoes changes in hormonal tone, the volume of fluid increases and the chemical composition of the blood changes.

normal pressure up to the 20th week of pregnancy, 120 to 80 is considered. A decrease of 5-10 units is allowed. From the 20th week, the pressure normalizes, however, in 20% of pregnant women, an increase of 5-10 mm Hg is possible. Art.

In the first trimester pressure decreases due to the production of the hormone progesterone, which dilates blood vessels . In the third trimester blood volume increases from 3 to 4.5 liters per minute. By increasing the load on the blood vessels, blood pressure increases.

The normal blood pressure for pregnant women ranges between 90/60 and 140/90 mm Hg. Art.

Causes and symptoms of high blood pressure

An increase in pressure is a natural reaction of the body to danger or stress. In such cases, adrenaline is released into the blood, the heart works faster, muscles contract, blood vessels constrict, and blood pressure rises. Thus, the body redistributes resources to save itself. But in the 21st century, a person is constantly under stress and stress, which is why high blood pressure becomes unbearable. defense mechanism but a direct threat. The causes of hypertension are experiences, regular stress, lack of sleep.

Doctors call other signs of hypertension:

• Overweight and obesity:
• Heredity;
• Violation of the kidneys and thyroid gland;
• Taking vasodilators.
• Groups of people with high risk development of hypertension
• In people whose parents had high blood pressure;
• In people who are overweight. Such people lead a sedentary and unhealthy lifestyle;
• Suffering from atherosclerosis and osteochondrosis of the cervicothoracic region. In such cases, the vessels are compressed, resulting in increased blood pressure;
• In persons who are prone to overexertion and stress. In 70% of cases, hypertension has and psychological reasons occurrence: overload and unexpressed negative emotions, which increase the pressure;
• In people who have elevated level blood cholesterol;
• smokers;
• Patients with diabetes.

Short-term hypertension (lasting two to three hours) is not dangerous. It is worth paying attention to high blood pressure, which persists for a day or longer. This type of disease is dangerous with consequences and complications that are fatal.

Consequences and complications of hypertension:

• Heart failure;
• Atherosclerosis;
• Stroke;
• myocardial infarction;
• kidney disease;
• chronic disorder cerebral circulation;
• Complications diabetes;
• Erectile disfunction;
• metabolic syndrome.

Some of the complications listed above lead to disability, disability, and even death. For this reason, it is important to know the main symptoms of hypertension at the initial stage.

Symptoms of hypertension:

• sweating;
• swelling of the hands;
• redness of the face;
• Memory impairment.

First form disease is considered mild. The pressure in this case ranges from 140-159 to 90-99 mm Hg. Art. Turning to a doctor, you can restore blood pressure to its original values ​​in 2-3 weeks.

Second form hypertension rises already to the following values: 160-189 / 100-109.

At this stage, there are symptoms as:

• headaches;
• Discomfort in the region of the heart;
• Vertigo.

The second stage of the disease is dangerous because the pressure 160-189 / 100-109 affects the organs, especially the eyes (vision worsens). It also increases the risk of having a stroke. To restore normal values will require medical treatment. Doing healthy lifestyle life in this case is no longer enough.

Third form hypertension poses a serious threat to life. At a pressure of 180/100, the vessels experience an enormous load, and irreversible consequences occur in the cardiac system, resulting in:

• Heart failure;
• angina;
• myocardial infarction;
• Arrhythmia;
• Other diseases.

In the second and third degree, a serious threat to human life is a hypertensive crisis, in which the lower pressure rises. This phenomenon is accompanied symptoms: dizziness, headaches, vomiting and nausea.

Causes and symptoms of low blood pressure

Low blood pressure is called hypotension. The amount of reduction is individual but is typically below 100/60 mmHg for men and 95/60 mmHg for men. for women.

Causes of hypotension:

• Sharp allergic reactions(anaphylactic shock);
• Inside heart blockade and myocardial infarction;
• Arrhythmia with a severe course;
• Volumetric blood loss.

Separately, it should be noted the causes of hypotension in women. Due to the features female body the list of reasons is longer. A common case of fixed hypotension in pregnant women. Depends on the duration of the child. At different months of pregnancy observed different kind hypotension. The decrease in blood pressure in the first trimester occurs as a result of the production of the hormone progesterone. In the last trimester before childbirth, the cause of low blood pressure is a physically growing belly. It also leads to hypotension. Iron-deficiency anemia.

Low blood pressure is easily diagnosed using a tonometer. This is an easy-to-use device that many people have at home. Single pressure measurement and detection low scores do not indicate hypotension.

However, apart from lower scoreshypotension is diagnosed by a number of accompanying symptoms:

• General weakness. Characterized by poor health visible reasons: lethargy, distraction, apathy;
• Insomnia. Constant feeling drowsiness, especially in the morning;
• Vomiting, shortness of breath;
• Arrhythmia;
• excessive sweating and dizziness when walking.

The appearance of dizziness when getting up from a bed or chair is the first sign of low blood pressure.

The danger of a sharp pressure drop provokes:

• kidney failure;
• Violation of consciousness;
• Fall into a coma.

Main risk factors:

• Dysregulation of vascular tone;
• Insufficient high-calorie food;
• Overwork;
• Heart disease.

Individual pressure

Blood pressure indicators go down and up 3-5 times a day. Therefore, the normal blood pressure is individual concept for some people. For example, for a girl with a height of 165 cm and 10% body fat, 100/60 can become the norm for blood pressure, while for a man of an athletic build, 130/90 mm Hg is considered the norm. Art.

Factors that affect individual blood pressure indicators:

• Feature of vascular tone: elastic, standard, elastic;
• Heart rate.

To reveal individual rate, would need:

1. Carry out measurements of blood pressure with a tonometer during the period wellness;
2. during dizziness, nausea, weakness, other ailments.

You should consult a doctor if, with excellent health, blood pressure indicators are 20-30 units higher than the permissible blood pressure limit of 140/90.

How to measure pressure correctly?

Blood pressure measurements are made in medical institutions, pharmacies and at home. The procedure is simple, and with the advent of electronic devices, minimal skills are required from the user. But to get true values BP, you will need to comply following rules :

1. Before measuring, rest and relax for 5-10 minutes. If before the measurement the person was stressed or training with weights, it is recommended to relax for at least 15-20 minutes;
2. Do not smoke or consume alcoholic and caffeinated drinks;
3. The arm with which measurements will be taken is bent 10-15 degrees at the elbow and placed on a flat surface. The pressure in lying patients is measured on a relaxed straightened limb;
4. Put on the cuff 5-10 cm above the elbow, and direct the pipes coming out of it parallel to the elbow bend.

Using electronic device during the measurement period, relax your hand, breathe evenly and do not talk. When measuring with a hand-held device with a phonendoscope, the assistance of another person is desirable. Self-inflation of the cuff with a mechanical pump and listening to heart sounds is problematic due to tension. In this case, the indicators of the tonometer increase by 5-10 units.

Normalization of blood pressure

Blood pressure with age or for other reasons deviates from the physiological norm. Such people are called: hypertensive and hypotensive. Both conditions are harmful to human health or become deadly. If pressure is detected above 140/90, descent measures are applied.

Rules for the normalization of pressure without the use of tablets:

• Normalize weight;
• Reduce the intake of salt in the daily diet;
• Include walking in the daily routine;
• Enrich the diet with foods that contain a lot of potassium;
• Add dark chocolate to your diet
• Avoid drinks containing caffeine.

In order for the pressure to be optimal for the body, it will be required normalize weight. The weight norm for men is calculated by the formula: height in cm minus 100. For example, for a person with a height of 175 cm, 75 kg is optimal. The standard weight for women is calculated using the formula: height in cm x bust in cm / 240 = ideal weight.

Decrease in diet daily allowance table salt lowers the pressure readings. For patients with hypertension, it is recommended to consume no more than 5 grams of salt per day. Many foods contain a sufficient amount of salt, which should also be taken into account when calculating the diet. For example, animal products contain much more salt than plant-based foods.

Eating foods containing potassium normalize blood pressure. Treatment of the disease begins with diet. With diseases of the cardiovascular system, people need to consume up to 2-4 thousand milligrams of potassium per day. Potassium-rich foods: dried apricots, legumes, melons, raisins, potatoes, bananas, orange juice, grapes. When choosing proper diet over time it will be possible to exclude pills.

Dark chocolate thanks to flavonoids it is able to favorably influence the state of blood vessels. This component increases the elasticity of blood vessels. Therefore, the use of at least 15 grams of dark chocolate per day can affect their tone.

Avoid caffeinated drinks they are replaced green tea. The standard dose of coffee is 3 cups per day, which increase blood pressure and keep them unchanged throughout the day. This phenomenon occurs as a result of vasoconstriction and an increase in peripheral resistance.

Infusions, decoctions, fresh juice of the plant are prepared from nettle. The latter lowers blood pressure faster. Drink three times a day, one tablespoon.

Juices, compotes, infusions are prepared from viburnum. The berry is able to normalize vascular tone and positively affect the work of the heart. For cooking, you need to grind viburnum berries and pour them with two glasses of boiling water for two tablespoons of berries. You can use it with honey. Please note: freshly squeezed juice acts faster on the body.

It is useful for hypertensive patients to drink herbal tea. You can cook it yourself. For this, dry pharmaceutical herbs. The following are suitable for tea: motherwort, valerian, hawthorn, cumin. Blood pressure is reduced by relieving vasospasm.

A simple way to lower blood pressure is to use birch sap, a decoction of leaves or buds. Means normalize the work of the kidneys, improve metabolism and vascular tone.

Tablets for the normalization of blood pressure:

• calcium antagonists;
• alpha receptor blockers;
• Beta receptor blockers;
• Diuretics;
• Angiotensin enzyme inhibitors.

The doctor prescribes diuretics for a month or two. The disadvantage of the drug is the excretion of calcium from the body. Possible fainting.

Beta receptor bokators have been popular for decades as a blood pressure drug. Today their use is limited due to such side effects like nausea, dizziness, headaches.

Blood pressure is reduced urgently by the following drugs:

• sodium nitroprusside;
• Nifidipine;
• clonidine;
• Furosemide;
• Captopril;
• Nitroglycerine.

In case of hypertension, on hand should be drugs emergency assistance : nifidipine, captopress, capoten. Capoten is used inside or under the tongue. First dose trial: up to 6 tablets of 25 mg. With good tolerance, another 25 mg is added. The effect of the drug occurs after 90 minutes and lasts 6 hours.
