Check. Change. Control. How Blood Pressure is Measured How can you tell what your blood pressure is? By using a device called a blood pressure monitor, your healthcare provider can measure your blood pressure to see if it’s in a healthy range. You’ve probably had your blood pressure taken during a visit to your healthcare provider’s office. Your blood pressure is recorded as two numbers. The systolic blood pressure (the “upper” number) tells how much pressure blood is exerting against your artery walls while the heart is pumping blood. The diastolic blood pressure (the “lower” number) tells how much pressure blood is exerting against your artery walls while the heart is resting between beats. Blood pressure is measured in units of millimeters of mercury, or mm Hg. For example, a blood pressure reading might be 120/80 mm Hg. 4
