Establishing Baseline Measurements

The most important method to get an accurate blood pressure

measurement is consistency. To get the most benefit out of your monitor,

it is important to establish a "baseline measurement." This helps build a

foundation of measurements that you can use to compare against future

readings. To build this baseline measurement, devote two weeks for

consistent blood pressure monitoring. This involves doing everything

the same way when you measure (e.g. measuring during the same time

of day, in the same location, sitting in the same chair, using the same

cuff, etc.). Once you establish your baseline measurement, you can start

evaluating if your measurement has been affected based on things like

lifestyle changes or medication treatment.

How Do I Record My Blood Pressure?

Blood pressure readings are typically recorded with the systolic pressure

written first, followed by a slash mark and the diastolic pressure. For

example, 120 mmHg systolic and 80 mmHg diastolic measurements are

written as 120/80. Pulse is simply written with the letter "P" followed by

the pulse rate—P 72, for example. Please see the back of the manual for

the blood pressure tracking record.
