The range of normal blood pressure in human body

The range of normal blood pressure in human body

In the range of normal blood pressure, the human heart can produce a certain pressure, so that blood can be transported to all parts of the body. This pressure is called blood pressure. People's blood pressure will fluctuate to a certain extent, neither too high nor too low, otherwise there is a problem with health. The following is the range of normal blood pressure values.

The range of normal blood pressure is 1. Pay attention to the problem of normal blood pressure. Normal blood pressure at all ages is convenient for modern people to know their blood pressure in time, find high blood pressure in time and treat it in time. Hypertension has become one of the diseases that harm modern people. As a kind of "invisible killer", it puzzles the life of modern people and creates a series of troubles for modern people.

Therefore, modern people should have the consciousness of active treatment and prevention. If you are a patient with hypertension, you should treat the patient according to the doctor's requirements for hypertension symptoms.

If you are not a hypertensive patient, you should also develop a sense of prevention. Through scientific data and regular blood pressure measurement, we can find high blood pressure as soon as possible, treat it as soon as possible, and know our normal blood pressure in time. The range of normal blood pressure is 90- 140. The low pressure is between 60 and 90. The normal range of pulse is: 60 to 100 beats per minute. As long as it is within this range, everything is normal. If you are measuring blood pressure, you can't take the result of one measurement as the standard, you should measure it at least three times.

Factors affecting blood pressure

Blood pressure is measured in millimeters of mercury. According to WHO 1999 guidelines, the ideal systolic/diastolic blood pressure is below 120/80, normal blood pressure is below 139/89, and hypertension is above 140/90 to 160/95. Blood pressure allows blood to be transported to the whole body normally in arteries. If blood pressure is too low, blood can't be supplied to the whole body. On the contrary, if blood pressure is too high, it may damage blood vessels, which also reflects that there may be abnormalities in blood or heart. Blood pressure is affected by the following factors:

1, height: The higher the body, the greater the pressure the heart needs to pump blood, so that blood can flow all over the body.

2, age: the younger the age, the higher the metabolic rate, the greater the blood flow, the heart needs more pressure to pump blood, with the increase of age.

3. Blood viscosity (blood density): The thicker the blood, the greater the pressure required for the heart to pump blood.

4. posture: blood pressure is higher when standing than when sitting, and blood pressure is higher when sitting than when lying flat. Affected by the principle of gravity.

5. Vascular quality: If blood vessels become narrower, it is more difficult for blood to pass through, and the heart needs more pressure to pump blood.

6. Others: mental state, life rhythm, personal differences, eating habits, drugs, heredity, weather changes, etc.

The range of normal blood pressure value of human body 2 The range of normal blood pressure value of human body is unknown to most patients and friends. Normal blood pressure should reach the ideal blood pressure, that is, 120/80mmHg. But in fact, there is a range of blood pressure fluctuations, as follows:

1, systolic blood pressure, that is, hypertension, is about 90- 140mmHg. If the systolic blood pressure is lower than 90mmHg, hypotension will occur, and patients will feel dizzy, chest tightness and uncomfortable. If the blood pressure is higher than 140mmHg, hypertension should be considered;

2. Diastolic pressure, that is, low pressure, also has a range, which should generally be 60-90mmHg. If the organ below 60mmHg is not perfused enough, the patient will also have dizziness and chest tightness. If the diastolic blood pressure is higher than 90mmHg, the diagnosis of hypertension should be considered.

So the normal range of blood pressure actually fluctuates greatly. In summer and winter, the blood pressure value is different, but the fluctuation is still within the normal range. Therefore, after the patient has mastered it, he will know when it is hypotension and need to take measures; When is hypertension, you need to see a doctor in time for antihypertensive treatment or examination to reduce your own risk.

Normal blood pressure range of human body

Anyone who has had a physical examination knows that the blood pressure of healthy adults is generally between 80~ 120, which is also the healthiest range. However, people of different ages have different values of normal blood pressure range. For example, for teenagers, the blood pressure value will be low, which is normal between 73- 1 15. The blood pressure of middle-aged and elderly people will gradually increase. For example, a 60-year-old man's normal blood pressure range is 84 to 137, as long as it does not exceed 137.

In addition, the healthy blood pressure values of men and women are slightly different. Usually, women's blood pressure will be slightly lower than that of men of the same age, but the difference will not be great.

The above is a brief introduction to the range of normal blood pressure. It is also a necessary health care measure to check your blood pressure regularly. Especially those who have a history of cardiovascular and cerebrovascular diseases at home should bring their own sphygmomanometer or electronic sphygmomanometer to measure their blood pressure every day. If there are abnormalities, you can go to the hospital for further examination, so that you can find unhealthy diseases in advance.

The range of normal blood pressure in human body is 3 1. What is the normal blood pressure?

In a quiet state, the normal blood pressure range of adults is systolic blood pressure 90- 139mmHg, diastolic blood pressure 60-89mmHg, generally systolic blood pressure less than 120mmHg, and diastolic blood pressure less than 80mmHg.

However, blood pressure is influenced by age, sex and environment. For example, with the increase of age, systolic blood pressure and diastolic blood pressure tend to increase gradually, but the ratio of systolic blood pressure to diastolic blood pressure is more obvious. Blood pressure will be lower during rest and sleep than during exercise, but it will be higher when excited. But these are normal conditions, fluctuating within the normal blood pressure range.

Second, what are the diagnostic criteria for hypertension?

1. Blood pressure was measured three times on the same day under the condition of being quiet and not taking drugs. Hypertension can be diagnosed if systolic blood pressure ≥ 140mmHg and/or diastolic blood pressure ≥90mmHg.

2. If the systolic blood pressure is greater than or equal to 135 and the diastolic blood pressure is greater than or equal to 85mmHg, this situation can also be diagnosed as hypertension.

3, systolic blood pressure is greater than 130mmHg, and/or diastolic blood pressure is greater than 80mmHg, which is also diagnosed as hypertension.

3. What are the hazards of hypertension?

1. Heart injury: Long-term increase of blood pressure and aggravation of left ventricular afterload often lead to compensatory left ventricular hypertrophy, heart failure, hypertensive heart disease, angina pectoris, myocardial infarction and other diseases, which seriously endanger human health.

2, damage to blood vessels: long-term hypertension can rupture hardened blood vessels, leading to massive bleeding, with serious consequences.

3, kidney injury: long-term hypertension will make the renal arteriole harden, nephron atrophy or disappear, often leading to polyuria, and then reduce urine volume, and even uremia.

4. Brain injury: The higher the Xu Ya of hypertensive patients, the greater the probability of stroke. If hypertensive patients have dizziness, headache, nausea, numbness, fatigue and other symptoms in their lives, they should be alert to the possibility of stroke.

In short, if you know the range of normal blood pressure, you can understand your body. In life, you can also measure your blood pressure and pay attention to your health. Especially for middle-aged and elderly people, blood pressure should be measured regularly. If there is an abnormal situation, you should go to the hospital for treatment in time to prevent the occurrence and deterioration of hypertension. Moreover, blood pressure is also an important content in diagnosing diseases, observing disease changes and judging treatment effect, which can not be ignored.
