What is normal blood pressure for all ages?
VerifiedHealing with compassion, caring with dedication.
Children's normal blood pressure is generally calculated according to the formula, and the normal value of adult blood pressure is systolic pressure 90-139mmHg, diastolic pressure 60-89mmHg.
Because children are still in the growth and development stage, blood pressure is unstable, so the normal value of children's blood pressure is generally calculated according to the formula, that is, normal systolic pressure (high pressure) is equal to their own age *2+80mmHg, diastolic pressure (low pressure) is 2/3 of the calculated systolic pressure, usually the younger the age, the lower the blood pressure value. However, for adults, systolic blood pressure of 90-139mmHg and diastolic blood pressure of 60-89mmHg are generally considered as normal blood pressure ranges. If blood pressure is higher than normal for three times in the same day, hypertension can be diagnosed.
