The heart acts as a motor, driving blood away.vessels, and in the large arteries of the circulatory system there is a pressure drop, which contributes to the promotion and distribution of blood throughout the body. Blood pressure norm is when its two indicators (systolic and diastolic) correspond to age indicators in both levels, upper (systolic) and lower (diastolic).
Систола – это давление крови в момент сокращения heart in maximum stress. Diastole is the moment in the work of the heart when it is as relaxed as possible. Blood pressure, upper and lower, is measured in millimeters marked on a mercury column, as in a thermometer. When the pressure level is 120/80 mm. Hg Art., you can go into space, because for the human body - is the norm of blood pressure.
Do not make a diagnosis instead of a doctor
It is necessary to measure the pressure in old age.There is nothing difficult in this procedure, below we will focus on this in more detail. But measuring pressure is one thing, and diagnosing yourself and prescribing treatment yourself is another. Take the same pills that a girlfriend or a neighbor, not worth it.
Blood pressure norm for each ageand the individual is determined by the doctor, as well as the degree of damage to the internal organs in case of hypertension. When blood pressure is constantly elevated, the risk that diseases will develop — heart, cerebral circulation, leg vessels, ischemia or stroke, kidney failure, or eyes — increases manifold.
How often and how to measure blood pressure
This question should be addressed for each person.individually. At a young age, there is no need to measure it often, and an over-pressured pensioner needs to measure it more than once a day. Normal pressure is considered when it has an upper index less than 130 mm Hg, and the lower one is less than 85. Hypertension is determined even when the pressure exceeds 140/99 mm Hg. and above, the degree of its development is determined by the doctor.
Blood pressure norm is notconstant, with age it can change. Even during the day, the pressure may increase or decrease from the physical, emotional state, from what medicines the person took.
The following are recommendations on how to measure blood pressure correctly:
- Need to sit down and relax. If the person is lying, then the arm should be stretched along the body.
- No need to eat for an hour or half an hour before measuring pressure, take medicine or smoke.
- After a person quietly sits for 5 minutes, you can measure the pressure.
- When a person is sitting, he better lean on the back of the chair. The location of the cuff should be at heart level.
- If pressure is measured in the prone position, something must be put under the arm so that it is also at heart level.
- You can not speak or move sharply, change the position of the body.
- When conducting a series of measurements, you need to take intervals, loosen the arm grip and take the next measurement in 1-2 minutes.
- Bracelets, watches or jewelry need to be removed, it is desirable to impose a cuff on a bare arm (if it is Korotkov's tonometer). If it is electronic, then the cuff is put on the wrist.
- The indication from the hand on which the highest pressure value is detected is taken into account.
- Sometimes the pressure rises only because it is measured by a doctor, this is called “white coat syndrome”, so 2-3 readings will not be superfluous.
- Children have different pressure from adults. Therefore, special children's tags are put on the device, there are children's cuffs. Measure the pressure of children in the clinic.
- For elderly hypotensive patients and those who are familiar with postural hypotension (sharp pressure fluctuations when standing up), it is necessary to measure the pressure of both sitting and lying down.
