Using a Home Blood Pressure Monitor
Accurate readings depend on preparation. Do not drink caffeine, exercise, or smoke for 30 minutes beforehand, and empty your bladder first. Take your readings at the same times each day, such as before breakfast and before dinner.
Begin by sitting in a straight-backed chair with your feet flat on the floor and your legs uncrossed. Rest quietly for five minutes; do not wrap the cuff until this rest period is over. Then slide the cuff onto your bare upper arm so that its lower edge sits about one inch above the elbow crease. The cuff should be snug enough that you can fit only one finger beneath it.
Before you press START, rest your arm on a table so the cuff is level with your heart, palm facing up. Pressing START with the arm hanging at your side will produce a falsely high reading. Stay still and silent while the cuff inflates and deflates. When the numbers appear, write them in your log along with the date and time.
If you plan to take a second reading, wait one minute and repeat the process. If a reading seems unusually high, wait five minutes and measure again; if it remains high, contact your health care provider. Bring your log to every appointment so that your provider can see patterns over time rather than a single number.
