Arterial blood pressure is a purely individual indicator and depends on many factors. And, nevertheless, there is a certain average medical rate. That is why deviations from accepted indicators allow the doctor to suspect malfunctions in the work of body systems.
However, we must remember that the indicators may vary. It depends, for example, on the time of day, as well as the age of the person. So, human pressure is the norm by age, what is it?
What is blood pressure?
Behind this concept lies the force that the blood flows on the walls of blood vessels. Blood pressure indicators depend on the speed and power of the human heart, as well as the total volume of blood that it can flow through itself within a minute.
And the recognized rate of pressure by age is one of the medical indicators of the proper functioning of the heart, the autonomic nervous system, as well as the endocrine one.
Normal pressure in an adult should be determined only at rest, since any loads (both physical and emotional) have a huge impact on his performance. The human body controls blood pressure independently, and with moderate load its indicators rise by about 20
If we talk about what kind of blood pressure is considered normal, then at the moment medicine is recognized to be within 91 … 139/61 … 89
With age, the human body undergoes irreversible processes that provoke an increase in pressure throughout life. The older a person is, the higher his blood pressure is.
Blood pressure: the norm by age
What is the normal pressure of a person? The question is somewhat abstract, since the norm for each person, most often, is individual. Medical educational literature suggests taking figures as 120/80
Normal blood pressure for a person aged 16 … 20 years may be slightly reduced. This applies to both systolic and diastolic index. Overall pressure at rest 100/70
The pressure standards for age (the table is presented a little below) are determined by the following indicators:
As the table of human pressure shows, age-related changes relate to both upper and lower blood pressure indicators. But we must remember that these are only averaged clinical indicators.
But not only an increase, but also a decrease in blood pressure indicators is a sure sign of deterioration in the activity of the body systems. That is why the ability to use a tonometer can be attributed to good prevention of almost all diseases. And in order to track the dynamics of pressure changes, it is necessary to keep a special diary.
How to measure pressure?
For measuring blood pressure, there is a special device – the tonometer. At home, it is most convenient to use automatic or semi-automatic devices, since measuring with a manual tonometer requires a certain skill.
To get the right results, you need to follow the following guidelines:
- before measuring the pressure, it is necessary to completely eliminate physical activity;
- no smoking;
- measuring blood pressure immediately after a meal will also give incorrect results;
- measure the pressure while sitting in a comfortable chair;
- the back should have a support;
- the hand on which the measurement is carried out must be located at the level of the heart,
Significant deviations from the norm require the mandatory consultation of a specialist doctor. Only a doctor, after passing through all diagnostic procedures, will be able to select an adequate treatment for the existing problem.
Deviation from the norm: probable causes
The reasons that can trigger changes in blood pressure, quite a lot. But the most common are the following:
- The inability of the heart to work as before and with the right strength.
- Change in blood quality. With age, it becomes more dense. And the thicker the blood, the harder it is to flow through the vessels. The cause of thickening can be, for example, such complex diseases as diabetes mellitus or autoimmune diseases.
- Reduced elasticity of blood vessels. This leads to improper feeding systems, increased loads, certain medications.
- The formation of atherosclerotic plaques that form when the content of bad cholesterol in the blood is elevated.
- Sharp changes in vessel lumen caused by hormones.
- Incorrect work of the endocrine glands.
The main part of the causes of pressure surges can be eliminated independently, which will keep you healthy as long as possible. Properly chosen diet, maintaining an active lifestyle, a relaxed attitude to life, which allows you to avoid stressful situations. Compliance with these simple rules allows you to normalize the pressure.
Pulse as an indicator of health
The next indicator of health status, along with blood pressure numbers, is the pulse. A pulse in the range of 60 … 80 beats / min is considered normal. The more intense the metabolism, the higher the number of beats per minute.
As well as for indicators of blood pressure, for different age categories have their own average norms.
