The heart works continuously, pumping the blood in the circulatory system to the body. When the heart pumps blood to the whole body through the aorta, a certain amount of pressure builds up in all the vessels. Intravascular pressure, defined as blood pressure, is of great importance for vital tissues and organs to be adequately nourished and to maintain their normal functions. The oxygenated blood in the lungs first comes to the heart and is pumped from there to the body through the aorta. The aorta, which can be defined as the main vessel leaving the heart, divides into many branches. These large vessels are known as arteries or arteries.
The great vessels are also divided into branches and become thinner arterioles, or in other words, they are connected to medium-sized vessels and finally to capillaries known as capillaries in medical language. Thanks to this entire vascular network, different types of cells in the body are oxygenated and obtain the energy they need. After the oxygen carried in the veins is left to the body, the dirty blood returns to the heart via a vein or vein, and the heart sends it to the lungs by pumping it to re-oxygenate the blood. The blood is sent to the veins by the pressure created during the pumping process of the heart.
The pressure created at this time is at its highest level. The heart muscle then relaxes, during which timeless pressure remains within the blood vessels. The pressure created during the beating of the heart is defined as systolic blood pressure, while the pressure remaining in the vessels with the relaxation of the heart is defined as diastolic blood pressure. When blood pressure is measured, data for both pressure types are obtained. Frequently asked, “How is blood pressure measured?” Before moving on to the question “What is blood pressure?” must answer the question.
What is blood pressure?
The heart, which consists of a total of 4 chambers, works non-stop to pump 5 liters of blood per minute to the body. The 2 chambers in the upper part of the heart are called the atria, and the 2 chambers in the lower part are called the ventricles. The blood in the blood vessels enters the heart from the right atrium and is transferred to the right ventricle. With the contraction of the heart, the blood is sent to the lungs for oxygenation and returns to the heart after cleaning. It is then pumped from the left ventricle of the heart through the aorta to be sent to the whole body. In other words, during a single contraction, blood is pumped both from the right ventricle to the lung and from the left ventricle to the aorta. With the contraction of the heart, clean blood is sent to the body at certain blood pressure. The pressure that builds up inside the arteries is defined as blood pressure. Blood pressure causes some dilation of the veins. During the gap between the two contractions of the heart, the veins maintain blood flow by applying pressure to the blood. The pressure created during the pumping of blood by the heart and the blood pressure that continues to maintain the blood flow in the vessels is evaluated separately.
What is systolic blood pressure?
When the heart pumps blood to the body, or in other words, when the heart contracts, the pressure in the blood vessels is at its highest. This type of pressure is defined as systolic blood pressure. In large public tension, also known as the average systolic blood pressure value it is expected to be in the range of 120 to 130 mmHg. This range is due to the fact that blood pressure level differs from person to person. In the presence of different health problems or with increasing age, the veins may lose their flexibility. In this case, the person’s blood pressure value will be high.
What is diastolic blood pressure?
The heart continuously pumps blood to the body, beating an average of 100,000 times a day. In addition to the systolic blood pressure that occurs when the heart contracts, there is some pressure in the arteries between the two beats of the heart. Enlarged by the effect of the blood pressure created by the contraction of the heart, the vessels apply pressure to the blood during the heart’s beating interval, ensuring the continuation of blood flow. This pressure in the veins is known as diastolic blood pressure or popularly known as diastolic blood pressure. Diastolic blood pressure in the range of 70 to 90 mmHg is considered normal.
How is blood pressure measured?
Blood pressure can be measured with a device called a sphygmomanometer or with sphygmomanometers. It is recommended to use a sphygmomanometer for the most accurate measurement. The cuff of the sphygmomanometer device should be placed 2.5 to 3 cm above the inside of the elbow and wrapped around the arm. The stethoscope should be tucked under the cuff and pressed lightly. The sphygmomanometer is then inflated to 20 to 30 mmHg above the level at which blood pressure disappears. The control valve should be opened slightly and air should be vented at 2-4 mmHg per second. The first sound heard as the air is expelled determines the systolic blood pressure. The value at which the sound is inaudible is considered the diastolic blood pressure. The measurement should be made a total of 3 times with an interval of two minutes. People with a blood pressure value less than 130/85 mmHg should have a measurement every 2 years.
What should be considered during blood pressure measurement?
In addition to many diseases, it is necessary to measure blood pressure correctly in order to make a healthy blood pressure measurement, which is also used in the evaluation of the general health status of the person, and to monitor the blood pressure of the person. For accurate blood pressure measurement, the following should be considered:
- The person should not exercise, eat, drink caffeine or smoke half an hour before the blood pressure measurement.
- Before measuring blood pressure, the person should rest for 5 minutes.
- The measurement should never be made over the clothes.
- The pouch inside the cuff should completely surround the arm.
- The arm for measuring blood pressure should be at heart level and the elbow should be supported by the other arm or a pillow.
- The stethoscope should be placed over the artery and kept balanced. The stethoscope should not be pressed too hard on the person’s arm.
- The hand should be released and the fist should not be made.
- Do not talk during the measurement.
- During blood pressure measurement, the legs should not be crossed.
- The systolic and diastolic pressures must be read at least three times for the correct measurement value.
What should be the ideal blood pressure value?
Although blood pressure differs from person to person, the ideal systolic blood pressure is in the range of 120 to 130 mmHg. Diastolic blood pressure, known as diastolic blood pressure, is considered to be in the range of 70-90 mmHg. In young people and children, lower values can be considered normal. Frequently asked questions “What should be the blood pressure?” This question can be answered in this way.
What is low blood pressure?
Low blood pressure is known as low blood pressure or hypotension. Low blood pressure, which is usually not objectionable, reduces the risk of developing cardiovascular diseases. Unless there is a very significant decrease in pressure, this situation does not cause any complaints in the person. However, a sudden drop in blood pressure can lead to symptoms such as dizziness, weakness, and fainting.
What is high blood pressure?
High blood pressure is popularly known as high blood pressure. A blood pressure value above 140/90 mmHg is also called hypertension. This condition, which can be seen at almost any age, mostly develops due to factors such as excessive salt consumption, obesity, diabetes, genetic factors, stress, cardiovascular, thyroid, adrenal gland, and kidney diseases. It is recommended that people with high blood pressure consume less salt, control their weight, and exercise regularly. Uncontrolled high blood pressure can lead to very serious health problems such as kidney failure, heart attack, and brain hemorrhage.
If you have a problem with blood pressure, do not neglect to apply to the nearest health institution and have your check-ups. We wish you healthy days.
