Here's how to interpret the data found elsewhere on the site:

Blood pressure is measured in mmHg - millimeters of mercury

Typical blood pressure is 120 / 80
"120" is systolic pressure in mmHg
"80" is diastolic pressure in mmHg

High blood pressure
a systolic pressure > 140 mmHg and/or
a diastolic pressure > 90 mmHg

Systolic blood pressure - maximum blood pressure during cardiac cycle

Diastolic blood pressure - minimum blood pressure during cardiac cycle

Mean blood pressure - average blood pressure during cardiac cycle
