Familiarity with blood pressure and how to diagnose it
If the pressure on the walls of the arteries by the bloodstream is higher than normal, the person has hypertension or high blood pressure. In this case, the heart has to move more to pump blood.
Blood pressure is measured in terms of both systolic and diastolic values. This naming is actually based on the same upper and lower limits.
What is systolic blood pressure?
After complete contraction, the heart pumps blood to the arteries and then rests between beats. On the other hand, due to the pressure inside the arteries as well as the intravenous valve, the blood returns to the heart and fills the right ventricle. This type of pressure is called systolic blood pressure.
blood pressure
Blood pressure is one of the main signs of a person’s life, and physics justifies this pressure by the amount of force that the blood circulation exerts on the walls of the arteries.
Scientifically, the level of blood pressure varies from place to place in the body’s circulatory system, as blood pressure flows through the arteries and decreases in intensity as it enters the arteries.
One of the simplest ways to measure blood pressure is to use a sphygmomanometer, which is available today in various types of digital sphygmomanometers and analog sphygmomanometers. One of the most suitable devices for measuring blood pressure is the mercury sphygmomanometer, which does this based on the height of the mercury. It is interesting to know that blood pressure is also measured in millimeters of mercury. This unit is also available for other devices that do not use mercury.
Blood pressure usually does not cause any symptoms, which is why most people with the condition are unaware of the condition in their circulatory system.
blood pressure
Scientists have dubbed the disease the silent killer because it has a very negative effect on the arteries and other vital organs.
Blood pressure for a resting person is in the range of 100 to 140 mm Hg (systolic) and its diastolic level is between 60 to 90 mm Hg. If a person’s blood pressure exceeds normal, he or she has a blood pressure complication.
High blood pressure is called high blood pressure or hypertension and low blood pressure is called hypotension.
Classification of resting blood pressure
Maximum number class
(Systolic)
Minimum number
(Diastolic)
Optimal / natural less than 120 less than 80
Pre-hypertension 120-139 80-89
Hypertension / Primary 140-159 90-99
High blood pressure / secondary 160 and more 100 and more
It is responsible for regulating blood pressure in the body, such as the heart, arteries and kidneys, and excessive salt consumption and the activity of hormones such as renin, angiotensin II, adrenaline and aldosterone affect its level.
Symptoms of high blood pressure
In general, high blood pressure is divided into primary and secondary categories, in the first type, there are no symptoms of the patient, but the secondary type of hypertension occurs after the occurrence of another disease. In this case, we must first seek control and treatment of the main disease, which will be followed by a more appropriate way to control blood pressure.
People with primary hypertension become aware of the disease in their circulatory system when they experience symptoms such as headache, blurred vision, chest pain, dizziness, and shortness of breath while exercising. These complications are characterized by a long period of disease. The only way to determine the first type of disease is to use a sphygmomanometer and measure your blood pressure regularly.
Age, sex, heredity, obesity and overweight, diet, diabetes, sedentary lifestyle, social and psychological factors, smoking and alcohol can double the risk areas for this disease.
