What is the concept of blood pressure?

Blood pressure is the blood pressure needed to act on the artery wall to bring blood to nourish the tissues in the body. Thanks to the force of heart contraction and arterial resistance, blood pressure is created.

Blood pressure depends on the force of the heart's pumping force. Blood pressure drops most rapidly when blood circulates in the small arteries, arterioles and continues to decrease as blood passes through capillaries and blood pressure reaches the smallest level in the venous system.

How much blood pressure is normal?

Blood pressure with 2 values ​​includes: Maximum blood pressure or systolic blood pressure, minimum blood pressure or diastolic blood pressure. People rely on these two values ​​to diagnose how blood pressure is normal. Whereby.

For adults:

  1. When systolic blood pressure from 140mmHg or more or diastolic blood pressure from 90mmHg or more is considered high blood pressure .
  2. When systolic blood pressure below 100 mmHg is considered low blood pressure or low blood pressure.
  3. The value between normal blood pressure and hypertension (systolic blood pressure from 120-139 mmHg or diastolic blood pressure from 80-89 mmHg) is called prehypertension .
  4. If systolic blood pressure is below 120mmHg and diastolic blood pressure is below 80mmHg, it is called normal blood pressure .

For children:

You should know that blood pressure will increase gradually as you grow. For babies or young children, there is usually no blood pressure problem so the doctor will not check this index.

If this number is higher than 95%, it is considered high blood pressure.

Which factors affect blood pressure?
