Why measure blood pressure?

Everyone should understand what the blood pressure of blood is, and for what it is measured, as it is an indicator of the vital activity of the body, as well as the general state of a person. It should be said that blood pressure is commonly called arterial pressure on the walls of arteries. Thus, the human heart in a relaxed state is filled with a liquid tissue of the body, which is pumped into the arteries. Thus there is a pressure systolic, and at a condition of a weakened heart - diastolic. Thus, the blood pressure depends on the amount of blood that the heart pumped over a certain period of time, its outflow, viscosity and pressure on the walls of the vessels. The pressure becomes higher with a larger amount of liquid tissue pumped into the artery, and lower - with less.

So, the pressure is usually written in two digits, the first of which indicates the strength of the onslaught with a contraction of the heart and is maximal, the second indicates the force of the onset when blood is discharged into the artery and is minimal. The difference between the maximum and minimum values is called pressure pulse. It can be said that blood pressure is a variable, as it is influenced by a large number of factors. A healthy person has normal indices of strength of pressure on the walls of arteries, usually it is 120/80 mm. Gt; In case of violation of the regulatory systems of the body, they may change.

It is necessary to know that with an increase in the indices for every ten units, there is a risk of developing cardiac and vascular diseases, therefore it is necessary to undergo examination if symptoms such as dizziness, headache, weakness, nausea occur.

In medicine, it is common to consider the indices of the average dynamic pressure, which is constant and indicates the energy of blood flow from the arteries to the veins.

The human body is able to regulate changes in blood pressure with baroreceptors, which send signals to the arteries, veins, kidneys and heart, and those in turn regulate pressure by changing the amount of blood in the arteries and veins. Thus, the human heart is capable of increasing its contractions, thereby increasing blood pressure, veins and arteries have the ability to narrow and expand, lowering or enlarging it.

Everyone has an individual blood pressure, the symptoms and indices of which depend on age, general health, emotional state, and lifestyle. If the mechanism of self-regulation of blood pressure fails, its indicators change. Their decrease is observed in poisoning, infections in the body, heart disease or blood vessels, and hypotension develops. Increasing them cause disruption of the kidneys, hormonal changes in the body, disruptions in the endocrine system, in this case they speak of hypertension.

In order to measure blood pressure, you can use two methods:

1. A mechanical device called a sphygmomanometer. His work is to measure the tones when the artery clamps the cuff.

2. Electronic devices that record pulsation when the cuff is squeezed by the cuff of the artery. Such devices can be semi-automatic and automatic.

It should be noted that blood pressure may be a symptom of the development of various diseases, therefore, with prolonged changes in its indices, it is recommended to consult in the clinic to determine the reasons for its fluctuation. Do not neglect your own health. After all, this can lead to unpleasant or even tragic consequences.
