Normal blood pressure at 60 years old. What is pulse pressure. Normal blood pressure in humans: upper and lower pressure

Arterial pressure- this is the blood pressure in the large arteries of a person. There are two indicators of blood pressure:

• Systolic (upper) blood pressure is the level of blood pressure at the moment of maximum contraction of the heart.
• Diastolic (lower) blood pressure is the level of blood pressure at the moment of maximum relaxation of the heart.

Arterial pressure measured in millimeters of mercury, abbreviated mmHg. Art. A blood pressure value of 120/80 means that the systolic (upper) pressure is 120 mmHg. Art., and the value of diastolic (lower) blood pressure is 80 mm Hg. Art.

Elevated numbers on the blood pressure monitor are associated with serious diseases, for example, the risk of cerebral circulation, heart attack. In case of chronic high blood pressure, the risk of stroke increases by 7 times, chronic heart failure by 6 times, heart attack by 4 times and peripheral vascular disease by 3 times.

What's happened normal pressure? What are its indicators at rest and during physical activity?

Arterial pressure divided into: optimal - 120 to 80 mmHg. Art., normal - 130 to 85 mm Hg. Art., high, but still normal - from 135-139 mm Hg. Art., at 85-89 mm Hg. Art. High blood pressure is considered to be 140 to 90 mm Hg. Art. and more. At motor activity Blood pressure increases in accordance with the needs of the body, an increase of 20 mm Hg. Art. speaks of an adequate reaction of cardio-vascular system. If there are changes in the body or risk factors, then blood pressure changes with age: diastolic pressure increases until age 60, and systolic pressure increases throughout life.

For accurate results, blood pressure should be measured after 5-10 minutes of rest, and one hour before the examination you should not smoke or drink coffee. During measurement, your hand should lie comfortably on the table. The cuff is attached to the shoulder so that its lower edge is 2-3 cm above the fold of the elbow. In this case, the center of the cuff should be above the brachial artery. When the doctor finishes pumping air into the cuff, he begins to gradually deflate it, and we hear the first sound - systolic.

To assess blood pressure levels, classification is used World Organization health care, adopted in 1999.

* If systolic and diastolic blood pressure are found in different categories, the highest category is selected.

** Optimal in relation to the risk of developing cardiovascular complications and mortality

The terms “mild”, “borderline”, “severe”, “moderate” given in the classification characterize only the level of blood pressure, and not the severity of the patient’s disease.

In everyday life clinical practice classification accepted arterial hypertension World Health Organization, based on damage to the so-called target organs. This is the most frequent complications, occurring in the brain, eyes, heart, kidneys and blood vessels.

What should a person's normal blood pressure be?What is a person's blood pressure that can be considered normal? The correct answer is: each person has their own norm . Indeed, the value of normal blood pressure depends on a person’s age, his individual characteristics, lifestyle, and occupation.

Normal blood pressure in newborns is 70 mm Hg.

Normal blood pressure in a child who is one year old: for boys - 96/66 (upper/lower), for girls - 95/65.

Normal blood pressure in a 10-year-old child: 103/69 in boys and 103/70 in girls.

What is the normal blood pressure for an adult?

Normal blood pressure in young people 20 years old: for boys - 123/76, for girls - 116/72.

Normal blood pressure in young people who are about 30 years old: in young men - 126/79, in young women - 120/75.

What is normal blood pressure for a middle-aged person? In 40-year-old men it is 129/81, in 40-year-old women it is 127/80.

For fifty-year-old men and women, blood pressure is considered normal: 135/83 and 137/84, respectively.

For older people, the following pressure is considered normal: for 60-year-old men 142/85, for women of the same age 144/85.

For older people over 70 years old, normal blood pressure is 145/82 for men and 159/85 for women.

What is the normal blood pressure for an old or elderly person? For 80-year-old people, blood pressure of 147/82 and 157/83 for men and women, respectively, is considered normal.

For elderly ninety-year-old grandfathers, normal blood pressure is considered to be 145/78, and for grandmothers of the same age - 150/79 mm Hg.

During unusual physical activity or emotional stress blood pressure increases. Sometimes this interferes with doctors when examining cardiac patients, who for the most part are impressionable people. American scientists even talk about the existence of the so-called “white coat effect”: when the results of measuring blood pressure in a doctor’s office are 30-40 mm Hg. Art. higher than with self-measurement his home. And this is due to the stress that the environment of the medical institution causes in the patient.

On the other hand, in people who are constantly exposed to heavy loads, such as athletes, a pressure of 100/60 or even 90/50 mm Hg becomes normal. Art. But with all the variety of “normal” blood pressure indicators, each person usually knows the norm of his blood pressure, in any case, he clearly perceives any deviations from it in one direction or another.

There are also certain blood pressure guidelines that change with age (norms for 1981):

However modern ideas about normal blood pressure are somewhat different. It is now believed that even slight increases in blood pressure over time can increase the risk of developing coronary disease heart disease, cerebral stroke and other diseases of the cardiovascular system. Therefore, normal blood pressure levels in adults are currently considered to be up to 130-139/85-89 mmHg. Art. The norm for patients with diabetes is considered to be a blood pressure of 130/85 mmHg. Art. A blood pressure of 140/90 refers to high standard. Blood pressure over 140/90 mm Hg. Art. is already a sign of arterial hypertension.

Normal pulse person

Pulse (lat. pulsus blow, push) - periodic fluctuations in the volume of blood vessels associated with contractions of the heart, caused by the dynamics of their blood supply and pressure in them during one cardiac cycle. The average healthy person normal resting heart rate is 60-80 beats per minute. So, the more economical metabolic processes, the fewer number of beats a person’s heart makes per unit of time, the longer duration life. If your goal is to prolong life, then you need to monitor the effectiveness of the process, namely your heart rate.

Normal heart rate for different age categories:

• child after birth 140 beats/min
• from birth to 1 year 130 beats/min
• from 1 year to 2 years 100 beats/min
• from 3 to 7 years 95 beats/min
• from 8 to 14 years 80 beats/min
• average age 72 beats/min
• advanced age 65 beats/min
• for illness 120 beats/min
• shortly before death 160 beats/min

Update: October 2018

As long as this parameter is within the normal range, you don’t think about it. Interest in this parameter appears from the moment when its failures become a tangible health problem. At the same time, there is a folk and scientific approach to assess this indicator - blood pressure, for brevity called the abbreviation blood pressure.

What is blood pressure

Even the immortal hero of Petrov and Ilf Ostap Suleiman Bertha Maria Bender-Zadunaisky subtly noted that “every citizen is pressed by a column of air with a force of 214 kilos.” To prevent this scientific and medical fact from crushing a person, atmospheric pressure is balanced by blood pressure. It is most significant in large arteries, where it is called arterial. The blood pressure level determines the volume of blood ejected by the heart per minute and the width of the vascular lumen, that is, resistance to blood flow.

• When the heart contracts (systole), blood is pushed into major arteries under pressure called systolic. Popularly it is called the upper one. This value is determined by the strength and frequency of heart contractions and vascular resistance.
• The pressure in the arteries at the moment of cardiac relaxation (diastole) gives an indicator of the lower (diastolic) pressure. This minimum pressure completely dependent on vascular resistance.
• If you subtract diastolic blood pressure from the systolic blood pressure figure, you get pulse pressure.

Blood pressure (pulse, upper and lower) is measured in millimeters of mercury.

Measuring instruments

The very first devices for measuring pressure were the “bloody” devices of Stephen Gales, in which a needle attached to a tube with a scale was inserted into the vessel. The Italian Riva-Rocci put an end to the bloodshed by proposing to attach a mercury monometer to a cuff placed on the shoulder.

Nikolai Sergeevich Korotkov in 1905 proposed attaching a mercury monometer to a cuff placed on the shoulder and listening to the pressure with the ear. Air was pumped out of the cuff with a bulb, the vessels were compressed. Then the air slowly returned to the cuff, and the pressure on the vessels weakened. Using a stethoscope, pulse tones were heard on the vessels of the elbow. The first beats indicated the level of systolic blood pressure, the last – diastolic.

Modern monometers are electronic devices that allow you to do without a stethoscope and record blood pressure and pulse rate.

How to measure blood pressure correctly

Normal blood pressure is a parameter that changes depending on a person’s activity. For example, with physical activity, emotional stress, blood pressure increases, with standing up abruptly may fall. Therefore, to obtain reliable blood pressure parameters, it must be measured in the morning, without getting out of bed. In this case, the tonometer should be located at the level of the patient’s heart. The arm with the cuff should lie horizontally at the same level.

There is such a known phenomenon as “white coat hypertension”, when a patient, despite treatment, persistently shows an increase in blood pressure in the presence of a doctor. Also, blood pressure can be raised slightly by running up the stairs or straining the muscles of the legs and thighs during measurement. To have a more detailed understanding of blood pressure levels this person, your doctor may recommend keeping a diary that records your blood pressure. different time days. They also use the method daily monitoring, when using a device attached to the patient, pressure is recorded for a day or more.

Blood pressure in adults

So how are u different people Because there are physiological characteristics, fluctuations in blood pressure levels may differ among different people.

No idea age norm Blood pressure in adults. In healthy people at any age, pressure should not exceed the threshold of 140 to 90 mmHg. Normal blood pressure readings are 130 to 80 mmHg. The optimal numbers “like an astronaut” are 120 to 70.

Upper pressure limits

Today, the upper limit of pressure, after which a diagnosis is made arterial hypertension, is 140 by 90 mmHg. Higher numbers are subject to identification of their causes and treatment.

• First, a lifestyle change is practiced, smoking cessation, feasible physical exercise.
• When the pressure rises to 160 to 90, drug correction begins.
• If there are complications of arterial hypertension or accompanying pathologies(IHD, diabetes), drug treatment starts from lower levels.

During the treatment of arterial hypertension, the normal blood pressure that they are trying to achieve is 140-135 at 65-90 mmHg. In persons with severe atherosclerosis, the pressure is reduced more smoothly and gradually, fearing sharp decline Blood pressure due to the threat of stroke or heart attack. For kidney pathologies, diabetes and those under 60, the target numbers are 120-130 per 85.

Lower pressure limits

The lower limits of blood pressure in healthy people are 110 per 65 mmHg. At lower numbers, the blood supply to organs and tissues (primarily the brain, which is sensitive to oxygen starvation) deteriorates.

But some people live their whole lives with a blood pressure of 90 over 60 and feel great. Former athletes with hypertrophied heart muscle are prone to low blood pressure. For older people, it is undesirable to have too low blood pressure due to the risks of brain accidents. Diastolic pressure for those over 50 should be kept between 85-89 mmHg.

Pressure on both arms

The pressure on both hands should be the same or the difference should not exceed 5 mm. Due to the asymmetrical development of muscles on right hand, as a rule, the pressure is higher. A difference of 10 mm indicates probable atherosclerosis, and 15-20 mm indicates stenosis large vessels or anomalies of their development.

Pulse pressure

Black rectangles are pulse pressure in different departments heart and large vessels.

Normal pulse pressure is 35+-10 mmHg. (up to 35 years 25-40 mmHg, at older ages up to 50 mmHg). A decrease in it can be caused by a decrease in the contractility of the heart (heart attack, tamponade, paroxysmal tachycardia, atrial fibrillation) or a sharp jump in vascular resistance (for example, during shock).

High (more than 60) pulse pressure reflects atherosclerotic changes in the arteries and heart failure. It can occur with endocarditis, in pregnant women, against the background of anemia, intracardiac blockade.

By simply subtracting diastolic from systolic pressure specialists do not use more diagnostic value has variability in pulse pressure in humans and it should be within 10 percent.

Table of blood pressure norms

Blood pressure, the norm of which varies slightly by age, is reflected in the table above. BP is slightly lower in women at a young age against the background of a smaller muscle mass. With age (after 60) risks vascular accidents are compared in men and women, so blood pressure levels are equal in both sexes.

Blood pressure in pregnant women

In healthy pregnant women, blood pressure does not change until the sixth month of pregnancy. Blood pressure is normal in non-pregnant women.

Further, under the influence of hormones, some increases may be observed, not exceeding 10 mm from the norm. At pathological pregnancy Preeclampsia may occur with surges in blood pressure, damage to the kidneys and brain (preeclampsia), or even the development of seizures (eclampsia). Pregnancy against the background of arterial hypertension can worsen the course of the disease and provoke hypertensive crises or persistent increase in blood pressure. In this case, correction is indicated drug therapy, observation by a therapist or treatment in a hospital.

Normal blood pressure in children

For a child, the higher his or her age, the higher the blood pressure. The level of blood pressure in children depends on the tone of blood vessels, the working conditions of the heart, the presence or absence of developmental defects, the condition nervous system. For a newborn, normal blood pressure is considered to be 80 to 50 millimeters of mercury.

What normal blood pressure corresponds to a particular childhood age can be seen from the table.

Normal blood pressure in teenagers

Adolescence begins at the age of 11 and is characterized not only by the rapid growth of all organs and systems, the gain of muscle mass, but also by hormonal changes that affect cardiovascular system. At 11-12 years old, adolescents’ blood pressure ranges from 110-126 to 70-82. From 13-15 years old it approaches, and then becomes equal to adult standards, amounting to 110-136 to 70-86.

Causes of high blood pressure

• Essential arterial hypertension ( hypertonic disease, see) gives persistent increases in pressure and.
• Symptomatic hypertension(adrenal tumors, diseases renal vessels) gives a clinic similar to hypertension.
• characterized by episodes of blood pressure surges not exceeding 140 to 90, which are accompanied by vegetative symptoms.
• An isolated increase in lower pressure is inherent renal pathologies(developmental anomalies, glomerulonephritis, atherosclerosis of the renal vessels or their stenosis). If diastolic pressure exceeds 105 mmHg. for more than two years, the risk of brain accidents increases by 10 times, and a heart attack by five times.
,
• diseases of the hypothalamic-pituitary system.

With slight hypotension, people live quite fully. When the upper blood pressure drops significantly, such as during shock, the lower blood pressure is also very low. This leads to centralization of blood circulation, multiple organ failure and the development of disseminated intravascular coagulation.

Thus, for long and full life, a person should monitor his blood pressure and keep it within the physiological norm.

IN medical practice There are blood pressure standards, the violation of which reduces the patient’s performance and leaves him bedridden. In this state, a person cannot think soberly, the heart rhythm is disturbed, the pulse quickens, and there is a rush of blood. To avoid deviations, it is important to control blood pressure and clearly know the blood pressure norms by age.

Normal human blood pressure

To understand how important the ideal value of this indicator is, it is necessary to clarify the essence: this is the force with which the blood flow acts on the walls of blood vessels and capillaries. High rate AD makes it clear that circulatory system cannot cope with the load, is not able to withstand the onslaught. This is a real health problem that can lead to immediate hospitalization. It is very important to know what pressure is considered normal in order to stop the flow pathological process already on early stage.

The ideal measurement is a tonometer made within 1 minute, and the result on it is 120/80 mmHg. Art. The normal blood pressure of a person by age may differ slightly from the stated limits, but the normal value is appropriate if the patient feels great and has no complaints to the therapist at all. When blood pressure increases, you must take medical supplies, individually prescribed by the attending physician.

What is normal blood pressure for an adult?

It’s worth clarifying right away: if you compare a person’s blood pressure, the norm by age has certain differences. You should not compare these two indicators, since they are affected by various factors. If the patient is interested in what his blood pressure is, the norm in adults is 120/80 mm. rt. Art. for a period of 20-40 years. IN childhood the blood pressure limit is somewhat underestimated, in the elderly it is overestimated (against the background of existing chronic diseases).

Normal in children

In preschool and school periods, children's blood pressure is measured mainly by medical indications, therefore, there is no indicator of the so-called “children’s limit” as such. At the age of 16, the norm has already been established for teenagers childhood pressure by age, which is 100-120/70-80 mm. rt. Art. If the top or lower limits are violated, the child must be shown to a specialist, check the pulse, undergo a complete clinical examination to determine the pathogenic factor.

With an increased limit, the child may not be aware of health problems and experience headache, but don't complain. When the limit is reduced, passivity, lethargy, and the desire to occupy horizontal position. Parents must respond to a health problem; otherwise, stabilize general state will be very problematic. Treatment is not always medicinal; blood pressure can be stabilized with a daily regimen, proper nutrition, drinking plenty of fluids And by alternative means.

In men

In the organisms of representatives of the opposite sexes, the indicator of arterial blood strength differs within the same age. This is explained physiological characteristics, which you can find out in detail during a consultation with a specialist. For example, normal blood pressure in men aged 20-40 years should not go beyond 123/76-129/81. These are the optimal boundaries when a representative of the stronger sex feels great and does not complain about his health.

Among women

IN female body much more often there is a need to lower blood pressure. Representatives of the fairer sex are more prone to horse racing, as a result of which the blood rushes to the head, concentration and performance are lost. You can determine the real value using a tonometer, but it is important to know what a person’s pressure should be. Age restrictions It is also advisable to take into account. Thus, the norm of pressure by age in women is 120/75 from 20 to 35 years and 127/80 for the period from 40 to 50 years.

Blood pressure, norm by age: table

Normal blood pressure does not need to be adjusted and will be measured using a home blood pressure monitor. If defined low rate, it is impossible to do without medical participation - in otherwise the patient loses strength and consciousness, the movement of blood through the vessels slows down. When it is necessary to lower this indicator, a specialist also gives valuable recommendations, and according to age and concomitant diseases. Below is a table of human pressure by age, typical of a healthy person.

It becomes obvious how a person’s blood pressure changes - a specific age-specific norm for women and men in healthy body rises smoothly. In childhood (in a child), such a pattern is absent. Knowing what the normal blood pressure is for a person by age, it’s time to increase vigilance for own health, avoid in every possible way abnormal surges in blood pressure and the accompanying malaise. The strength of blood flow and pulse should always be normal, so the table clearly defines the permissible limits for human health.

Blood pressure and pulse are the most important parameters of the human body, by which one can judge the state of the body of an adult.

The systolic indicator is the first number that displays the intensity of the heart pushing blood into the vessels. The diastolic indicator is the second digit, recorded at the moment between contractions, and keyly depends on the functioning of the kidneys.

As a rule, interest in normal blood pressure indicators occurs when blood pressure surges occur and tangible health problems appear.

In this regard, it is necessary to find out what is a person’s normal blood pressure? What does pulse blood pressure mean? And what is the ideal blood pressure?

Before finding out what normal blood pressure should be in a person, it is necessary to understand what factors influence blood pressure readings.

Blood pressure is the force with which the blood flow acts on the vascular walls of blood vessels. The values ​​of its parameters are closely related to the speed and strength of heart contractions, as well as the volume of blood that the heart can pass through itself over a certain period of time - 1 minute.

In medical practice, there are established pressure indicators, that is, the average value that is assigned to a person by age depending on his gender.

It is these values ​​that show the degree of functionality with which the entire adult body works, and it is also possible to characterize some systems separately.

Blood pressure is considered an individual parameter, the indicators of which vary depending on various factors:

• The strength and frequency of heart contractions, which ensures the movement of blood through arteries, veins and vessels.
• Features of blood composition. There are characteristics of the blood that belong to a particular patient, as a result of which blood flow may become difficult and the force of blood pressure may increase.
• Atherosclerosis. If the patient has deposits on the vascular walls in the body, additional stress develops on them.
• Elasticity and resilience vascular walls. When worn out blood vessels, there are difficulties in blood movement under increased load.
• Blood vessels are excessively dilated/constricted. Typically, this vascular condition is provoked by emotional factors (stress, panic, nervous disorder).
• Features of operation thyroid gland, when with an excess of certain hormones, an increase in blood pressure parameters occurs.

Under the influence of these factors, blood pressure may differ from normal parameters. In view of this, human pressure is a purely individual and relative concept.

Everyone knows that the most ideal blood pressure is 120/80. But few people understand that such boundaries are quite blurred, because normal blood pressure is not exclusively 120/80, but an average value from 101/59 to 139/89 is considered normal.

Not only does blood pressure increase slightly with age, which is why the concept of working blood pressure appeared. This condition means a level of pressure that does not affect the person’s condition in any way, and it does not correspond to the accepted norm.

For example:

1. A 40-year-old woman has a blood pressure of 140/70. This pressure has a deviation from the average, but it does not have a detrimental effect on the body.
2. If you reduce the pressure to the required norm, that is, 120/80, then your health will worsen and unpleasant symptoms will appear.

However, there is an average blood pressure by age. Table of normal blood pressure by age:

• At 16-20 years old, normal blood pressure should be 100-120/70-80.
• At 20-30 years old, blood pressure should be 120-126/75-80.
• At 40 years old, 125/80 is considered normal.
• At 45 years old normal indicators 127/80.
• At 50 years old, the norm is 130/80.
• At 60 years old – 135/85, at 70 years old – 140/88.

As the table of pressure by age shows, age-related changes concern not only the systolic indicator, but also the diastolic one. However, you still need to understand that these are just average indicators, which are not always worth striving for.

At the age of 20 years, normal blood pressure may be slightly reduced; this decrease concerns two indicators. In general, at 20 years of age, a resting blood pressure of 100/70 is considered normal; with age, it becomes equal to the average parameters. You can find out in detail about everything the normal blood pressure by age, table and indicators.

Based on medical statistics, we can say that men over 40 years of age are at risk of developing arterial hypertension.

There is another generalized table of pressure standards, which represents more average indicators (the table was compiled in 1981):

1. 16-20 years old – 100-120/70-80.
2. 20-40 years – 120-130/70-80.
3. 40-60 years – the upper value is no more than 140, the lower value is no more than 90.
4. After 60 years – 150/90.

It is worth noting that the blood pressure of a man aged 20, as well as a woman of the same age, will differ slightly. U young guy the most ideal blood pressure value for this age is 123/76; for a 20-year-old girl it is 116/72.

Pulse pressure is the difference between systolic and diastolic readings. The normal difference should be from 30 to 50 mmHg.

Abnormal deviation from accepted norm significantly worsens the patient’s quality of life, health in general, and is also accompanied by unpleasant symptoms.

High pulse pressure in a person may indicate malfunctions in the functioning of the cardiovascular system, especially great importance differences inherent in people over 60 years of age. Increased pulse pressure is considered to be a pressure whose difference is more than 60 mmHg.

Such indicators have a very negative impact on the functioning of the body, because this state helps accelerate the natural aging of everyone internal organs, in particular this applies to the brain, kidneys, and heart.

Highlight various reasons such an anomaly:

• The reasons may lie in the stiffness of large arterial vessels.
• Hyperkinetic syndrome.
• Endocarditis, heart block.
• During pregnancy.
• Increased intracranial pressure.
• Anemia.
• Chronic heart failure.

It is worth noting that age does not affect the difference in pulse pressure, nor does a person’s gender. In case of a significant decrease or increase in indicators, you must immediately consult a doctor to determine the cause of this pathology and prescribe appropriate treatment.

Human blood pressure and pulse

Blood pressure and pulse are parameters that are mandatory removed by the attending physician. Normal blood pressure and pulse are the key good condition and human health. If there are deviations from the norm, we can say that some kind of pathology is developing.

Pressure and pulse are two interrelated quantities that in any case influence each other. For example, with increased blood pressure, the pulse rate increases, the beats of which the patient feels very clearly. Based on this, it is necessary to find out how many beats per minute is considered normal?

Like blood pressure, pulse has its own average norms by age:

1. Newborn child – 140.
2. 8-14 years old – 85, 16-20 years old – 80.
3. 20-30 years – 70, 30-40 years – 65,
4. 40-50 years old – 65.
5. During illness - 120, before death - 160.

Like blood pressure, pulse is measured by age, and as a person ages, the number of beats decreases, with the exception of times of illness. Why does the number of strokes decrease as a person ages?

The fact is that the more economical the metabolic processes in human body, the fewer number of beats the heart makes in a certain period of time, the longer the duration of human life.

In a completely healthy person (age is not important), the pulse has rhythmic properties, due to which pulse waves occur at regular intervals. If a violation occurs heart rate, pressure and pulse will change.

By measuring your pulse, knowing its normal values ​​for age, you can recognize an emerging problem. For example, if the number of beats per minute increases a couple of hours after eating, poisoning can be assumed.

The main way to determine the pulse is by palpating the arteries. As a rule, the radial artery is palpated: the patient’s hand is grasped in the area wrist joint, thumb the doctor is on back side forearms, other fingers - on the inner surface radius. What you need to know about heart rate measurement:

• If you position your fingers correctly, you can feel the radial artery, which continuously pulsates.
• Usually, when examining a person, the pulse is felt in both hands, since it is not always the same on the left and right hands.
• In some cases, the femoral, temporal or carotid artery. In these vessels the pulse rate is always the same.
• The duration of pulse measurement is half a minute, the result obtained is multiplied by two.
• When a patient has an abnormal heart rhythm, the pulse is always palpable for one minute.

When a patient has a tense pulse and the beats are felt quite clearly, then we can safely conclude that there is high blood pressure.

Blood pressure is an individual physiological indicator, which determines the force of blood compression on the walls of blood vessels.

In many ways, blood pressure depends on how a person’s heart works and how many beats per minute it can make.

A person’s normal blood pressure is an indicator that can vary depending on the physical load on the body.

Thus, during active training or strong emotional experiences, a person’s normal blood pressure can increase and go beyond the norm.

The ideal blood pressure reading at rest is 110/70. Low blood pressure starts at 100\60. Increased (hypertension) - from 140\90.

The critical (maximum) indicator is 200/100 or more.

A person's normal blood pressure may also change after physical activity. If the heart copes with its functions, then the change in blood pressure is not a deviation. So after sports loads a person's blood pressure may rise to 130/85.

There are factors that have a significant impact on the normal pressure (including intraocular, intra-abdominal, etc.) of a person:

1. The person's age and general health. It is important to know that existing diseases (especially chronic pathologies kidney, heart, sexually transmitted or viral diseases) can significantly increase blood pressure.
2. The presence of diseases that can thicken the blood (diabetes mellitus).
3. The presence of progressive abnormalities in pressure (hypertension, hypotension).
4. The condition of the heart and the presence of diseases in it.
5. Atmosphere pressure.
6. Thyroid hormone levels and menopause in women.
7. Hormonal disruptions in the body that narrow arteries and blood vessels.
8. General elasticity of vascular walls. In older people, blood vessels wear out and become brittle.
9. Presence of atherosclerosis.
10. Bad habits(smoking, drinking alcohol).
11. Emotional condition person ( frequent stress and experiences are reflected negatively on normal pressure person).

Normal blood pressure varies somewhat among women, adult men, and children.

In the event that a person experiences disruptions in this indicator and problems with blood pressure surges, he needs urgent medical assistance and medical treatment.

In addition, the pulse rate also plays a significant role, since the blood pulse is inextricably linked with venous pressure.

Normal blood pressure in humans: upper and lower pressure

Before we consider what upper and lower blood pressure are, we present the WHO classification of blood pressure.

According to WHO, the following stages of high blood pressure are distinguished:

1. The first stage is accompanied by a stable course of hypertension, without deterioration in the functioning of internal organs.
2. The second stage involves the development of pathologies in one or two organs.
3. The third stage affects not only organs, but also body systems. In addition, the following degrees of blood pressure are distinguished:
   • Borderline state, in which the indicators are no more than 159/99.
   • The second degree is moderate hypertension (179/109 or more).

Normal blood pressure in a person is a relative concept, since for each individual (individual) organism there are certain normal tonometer indicators.

Before understanding what a person's normal blood pressure is, it is important to understand what upper and lower blood pressure are.

Not everyone knows what upper and lower blood pressure are, and they often confuse them. Speaking in simple words, upper or systolic pressure is an indicator that depends on the contraction frequency and strength of the myocardial rhythm.

Lower or diastolic pressure is an indicator that reveals the minimum pressure during the decrease in load (relaxation) of the heart muscle.

What should blood pressure be by age and gender?

For men, the norms are:

1. At 20 years old - 123/76.
2. At 30 years old - 130/80.
3. At 50-60 years old - 145/85.
4. Over 70 years - 150/80.

In women, normal blood pressure readings are:

1. At 20 years old -115/70.
2. At 30 years old - 120/80.
3. At 40 years old - 130/85.
4. At 50-60 years old - 150/80.
5. Over 70 years - 160/85.

As you can see, blood pressure levels increase with age in both men and women.

Normal blood pressure in a person is inextricably linked with his pulse, which may also indicate various diseases and pathologies in the body (especially in the kidneys and blood vessels).

The pulse itself is nothing more than periodic contractions that are associated with the oscillation of blood vessels as they fill with blood. At reduced vascular pressure The pulse will also be weak.

Normally, at rest, a person’s pulse should be 60-70 beats per minute.

Highlight different standards pulse rate for people of different age categories:

1. In children from one to two years old - 120 beats per minute.
2. In children from three to seven years old - 95 strokes.
3. In children from eight to 14 years old - 80 strokes.
4. In adolescents and young adults - 70 beats.
5. In older people - 65 beats.

A person's normal blood pressure does not drop during pregnancy until the sixth month of pregnancy. After this, due to the influence of hormones, blood pressure may increase.

In the event that pregnancy occurs with deviations or pathologies, then jumps in blood pressure may be more noticeable. In this condition, a woman may experience a persistent increase in blood pressure. At the same time, she is recommended to register with a therapist and go to the hospital under the supervision of a doctor.

Before considering in what units blood pressure is measured, you should understand the rules of the procedure itself for establishing blood pressure indicators.

1. The person should take a sitting position with support on his back.
2. Before measuring blood pressure, it is not recommended to overexert yourself physically, smoke, eat, or drink alcohol.
3. You need to use only a working mechanical device to change blood pressure, which will have a standardized scale.
4. The person's hand should be at chest level.
5. You cannot speak or move during the procedure.
6. In measuring the pressure of both hands, you need to take a break of ten minutes.
7. A doctor or nurse should measure your blood pressure. A person will not be able to accurately determine his blood pressure on his own.

Not everyone knows in what units blood pressure is measured and what the “mm Hg” indicators mean. Art." In fact, everything is simple: these units of blood pressure mean millimeters of mercury. They show on the device how high or low your blood pressure is.

After we have figured out in what units blood pressure is measured, we will give the main reasons for deviations from the norm.

Pressure disorders in the body can develop for a variety of reasons. This could be physical fatigue, starvation, or simple stress that has greatly affected the person’s condition. Usually in this state the indicators themselves stabilize, when the body returns to normal, the person eats, rests and sleeps well.

More serious reason high blood pressure may become progressive diseases such as vascular atherosclerosis, diabetes mellitus, acute viral or infectious diseases. In this condition, a person may suffer from sharp jumps Blood pressure, as well as obvious signs of hypertension.

One more common cause failure in blood pressure is sharp narrowing blood vessels caused by hormonal influence, as well as emotional stress.

Taking certain medications, heart disease, bleeding disorders and excessive exercise can also affect the failure of this indicator.

Poor nutrition and malfunction endocrine system usually has a bad effect on blood pressure in both young and old people.

The difference between systolic and diastolic pressure: normal and abnormal

Blood pressure has two main indicators:

1. Systolic.
2. Diastolic.

There is a significant difference between systolic and diastolic pressure. The norm of upper (systolic pressure) is determined by the level of pressure in a person’s blood at the moment of the strongest (maximum) contraction of the heart.

Thus, the rate of systolic pressure directly depends on the heart rate and the number of its contractions.

There are factors that influence the normal systolic pressure:

1. Right ventricular volume.
2. The frequency of oscillations of the heart muscle.
3. A measure of the stretching of the walls in the aorta.

The normal systolic pressure is 120 mm. rt. Art. Sometimes it is called “heart”, but this is not entirely correct, because not only this organ, but also blood vessels are involved in the process of pumping blood.

The normal diastolic pressure depends on the level of blood pressure at the moment of maximum relaxation of the heart. Thus, the normal diastolic pressure is 80 mmHg.

Therefore, there is a fairly significant difference between systolic and diastolic pressure.

The norm is still individual for each person, depending on the state of health, age and gender.

High blood pressure or hypertension (hypertension) is usually found in older people. This disease is considered very dangerous because it can lead to a stroke, that is, rupture of a blood vessel in the brain.

Such a deviation can develop for the following reasons:

1. Excess weight of a person (obesity).
2. Strong nervous tension, frequent stress and psycho-emotional instability.
3. Chronic diseases internal organs.
4. Sedentary image life.
5. Diabetes.
6. Drinking alcoholic beverages.
7. Smoking.
8. Poor nutrition.
9. Genetic predisposition person to this disease.

During hypertension, a person suffers from terrible headaches, weakness, shortness of breath, dry mouth, heart pain and weakness.

In this condition, the patient must be provided with urgent help and consult a doctor before the disease causes dangerous complications. It is also important to identify the root cause of hypertension, and together with high pressure treat the factor that provoked its appearance.

Hypotension is a condition in which a person has low blood pressure. In this case, the patient will feel severe weakness, nausea, dizziness.

This condition can be caused by:

1. Anemia.
2. Heart attack.
3. Prolonged fasting.
4. Adrenal diseases.
