Blood pressure is one of the most important indicators of human health. To know what blood pressure is normal for you and to monitor its level is necessary for all without exception – the usual figures on the monitor can provide early warning of potential issues and help avoid troubles with health. A signal of dangerous changes in the body can become not only too high or too low, but normal for other people the pressure.
What is blood pressure?
Blood pressure (BP) is called the pressure force of blood against the artery walls. It depends on the strength and speed of contraction of the heart, blood properties, resistance of the vessel walls.
Blood pressure is measured in millimeters of mercury, where the first digit represents the value of the systolic (or upper) pressure and the second diastolic (or lower) blood pressure.
- Systolic pressure — the level of pressure of blood against the artery walls at the moment of maximum contraction of the heart.
- Diastolic pressure — the level of pressure of blood against the artery walls at the moment of maximum relaxation of the heart.
Standards standards of BP is determined by the classification of the world health organization.
Blood pressure 130/70 – the norm?
The normal BP of a person depends on his age, lifestyle, work and individual characteristics of the organism.
Despite this, there are several categories of blood pressure that can guide to decision making in seeking medical care or lifestyle change.
- Condition: top 100 below/down below 60. Requires mandatory medical supervision.
- Optimal blood pressure: the top 100-120/60-80 lower. Periodic independent control.
- Normal blood pressure: the top 120-130/80-85 lower. Periodic independent control.
- High-normal blood pressure: top 130-140/85-90 lower. Independent control and adjustment of lifestyle.
- Moderate hypertension: the top 140-160/ 90-100 bottom. A doctor’s advice.
- Hypertension average weight: top 160-180/ 100-110 bottom. A doctor’s advice.
- Severe hypertension more than 180 top/bottom 110. A doctor’s advice.
The pressure increase that accompanies the physical or psychological fatigue can be a symptom of an unstable or labile hypertension.
Doctor should turn, even if in most cases you have no problems with pressure. When diastolic pressure over 120 mm Hg you should immediately call an ambulance.
Some diseases can cause the correction of norms of arterial pressure in humans. For example, for patients with diabetes defined by its normal blood pressure: 130/70 – 130/85 mm Hg, a blood pressure above 140/90 mm Hg is a symptom of hypertension.
At the same time, the negative pressure may be normal for athletes, experiencing constant heavy loads.
It should be noted that the accuracy of the measurement of blood pressure can influence a psychological phenomenon called “White coat syndrome” due to fear and stress in the presence of doctors and accompanied by an increase in blood pressure of 20-30 mm Hg turning to the doctor or nurse.
Blood pressure and Age
A normal blood pressure in humans changes with age – the systolic BP increases throughout life, while diastolic increases until 60 years. It should be understood that in the elderly the risk of developing hypertension is great, despite a normal BP.
Normal blood pressure for age:
- infants: 70/55 mm Hg;
- kid 1: 95/65 mm Hg;
- child 10 years of age: 100/70 mm Hg;
- 16-20 years 100/70 – 120/80 mm Hg;
- 20-40 years 120/70 – 130/80 mm Hg;
- 40-60 years: to 135/85 mm Hg;
- over 60 years: to < 140/90 mm Hg.
In people older than 50 years are especially important to monitor upper blood pressure readings above 140 mm Hg are the reason for immediate treatment to the doctor.
If blood pressure 130/70 you feel good, that BP is a no-brainer for your body and health
Danger of high blood pressure
High blood pressure may be a symptom of a heart attack or stroke. Chronic high blood pressure greatly increases the risk of various diseases and complications.
In people with high BP the risk of stroke grows in 7 times, 6 times increased chances of developing chronic heart failure in 3-4 times increases the risk of peripheral vascular disease and heart attack.
In addition, there is a scheme according to which, starting from values of 115/75 mm Hg, the risk of stroke and heart attack grows twice at increase for every 20 points systolic pressure and 10 points diastolic.
What is blood pressure normal for you?
If the doctor recommended to conduct regular measurement of blood pressure at home, it will be useful to bring to the clinic your blood pressure, and together with the specialist to determine its probable error.
When locomotor activity increases BP by 20 mm Hg is the adequate response of the cardiovascular system to the needs of the body. Therefore, before the measurement of pressure must come into a state of rest, half an hour to eliminate physical exertion and nervous tension, and for 5-10 minutes before measurement to sit, leaning back in her chair.
Also required an hour to refrain from Smoking and coffee. In addition, the counter alcohol. Measurement should be taken on both hands, recorded the readings from the hand with the higher BP. It is desirable to measure blood pressure several times with an interval of 5-10 minutes.
Do not forget that the permanent self-monitoring of blood pressure will help to take the necessary measures and avoid the development of various diseases and their expensive treatment. Noting that several days in a row you have high or low blood pressure, hurry to go to the district hospital. Often the early stages of hypertension and hypotension accompany symptoms, taken by mistake for normal fatigue.
