Question

Average systolic blood pressure in humans

Answer 1

Blood pressure is measured using two numbers. The first number, called systolic blood pressure, measures the pressure in your blood vessels when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your blood vessels when your heart rests between beats.

If the measurement reads 120 systolic and 80 diastolic, you would say “120 over 80” or write “120/80 mmHg.”

The chart below shows normal, at-risk, and high blood pressure levels. A blood pressure less than 120/80 mmHg is normal. A blood pressure of 140/90 mmHg or more is too high. People with levels in between 120/80 and 140/90 have a condition called prehypertension, which means they are at high risk for high blood pressure.

Blood Pressure Levels:-

Normal -
systolic: less than 120 mmHg
diastolic: less than 80mmHg

At risk (prehypertension)-
systolic: 120–139 mmHg
diastolic: 80–89 mmHg

High-
systolic: 140 mmHg or higher
diastolic: 90 mmHg or higher
