Blood pressure reading is measured in two numbers - 120/80.
The above number is the systolic pressure, which is the pressure as the heart contracts and pumps blood into in the arteries.
The below number is diastolic pressure, which is the pressure in the arteries when the heart relaxes after contraction.
Blood Pressure Range
Normal - Blood pressure of 120/80
Pre-hypertension - Blood pressure between 120/80 and 139/89
High blood pressure - Blood pressure of 140/90 or above (consistently)
