When last have you had your Blood Pressure checked?
Blood pressure is the force of blood against the walls of arteries. Blood pressure is recorded as two numbers—the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats). The measurement is written one above or before the other, with the systolic number on top and the diastolic number on the bottom. For example, a blood pressure measurement of 120/80 mmHg (millimeters of mercury) is expressed verbally as "120 over 80."
Normal blood pressure is less than 120 mmHg systolic and less than 80
Category Systolic (Top number) Diastolic (Bottom number)
Normal Less than 120 Less than 80
Prehypertension 120-139 80-89
High Blood Pressure Systolic Diastolic
Stage 1 140-159 90-99
Stage2 160 or higher 100 or higher
