A&D Medical Wrist Digital Blood Pressure Monitor, Jumbo Screen

The A&D Medical UB-543 is a wrist digital blood pressure monitor (BPM) for checking your blood pressure at home or away from it, with nothing to wrap around your upper arm. Press START and it takes your systolic pressure, diastolic pressure and pulse as the cuff inflates, then shows them on a jumbo screen. Two people can share it, since each keeps their own memory of 60 readings, and a colored light tells you when your wrist is at the right height. It fits wrists 5.3 to 8.5 in (13.5 to 21.5 cm) around and runs on 2 AAA batteries. Sold individually.

What Your Blood Pressure Numbers Mean

Blood pressure is the force of your blood pushing against the walls of your arteries as your heart pumps. A reading is two numbers, written one over the other, such as 120/80 mmHg. The top number is your systolic pressure, taken as your heart pumps, when the pressure is highest. The bottom number is your diastolic pressure, taken as your heart fills, when the pressure is lowest. This monitor also gives your pulse in beats per minute.

Why Check Your Blood Pressure at Home

Most people with high blood pressure have no signs or symptoms, so many do not know they have it, and it raises the risk of heart disease and stroke. Blood pressure also changes throughout the day, so one reading at an office visit shows only one moment. Regular readings at home, alongside your checkups, give you and your doctor a fuller picture. With dated readings and morning and evening averages, you have the numbers in hand at your next appointment. Your doctor can tell you what they mean for you and whether anything should change.

Is a Wrist BPM Right for You?

An upper-arm cuff is the type most often recommended for home use. A wrist monitor can be the better fit when an upper-arm cuff is hard to use, such as on very large arms. Position is what makes or breaks a wrist reading, because a wrist held away from heart level can read falsely high, and that is the job of the blue and orange guidance light.

For a steady reading, relax for five to ten minutes first. Sit with your back straight, feet flat and legs uncrossed, rest your elbow on a table, and stay still and quiet. Try to measure at about the same time each day.

This monitor is intended for adults. Do not use it during pregnancy or on a wrist with an unhealed wound. If you have had a mastectomy or have a severe circulation problem in your arm, ask your doctor first.
