Home Blood Pressure Test
How It Is Done continued...
Take your new monitor to your doctor's office to make sure it is working
right. Have your health professional take your blood pressure and then compare
that result with your own device. Ask your health professional to watch you use
your monitor to make sure that you are using it correctly. It is a good idea to
have your monitor checked every year.
Check your blood pressure cuff
frequently to see that the rubber tubing, bulb, valves, and cuff are in good
condition. Even a small hole or crack in the tubing can lead to inaccurate
Taking your blood pressure
Your blood pressure in your right arm may
be higher or lower than the blood pressure in your left arm. For this reason,
try to use the same arm for every reading.
Ask your doctor if you should take your
blood pressure at the same time of day each time you take it, or if you should
take your blood pressure at different times of the day. Blood pressure readings rise
and fall at different times during the day. They are usually highest in the
morning and lowest in the evening.
At first it is a good
idea to take your blood pressure 3 times in a row, 5 or 10 minutes apart. As
you get more comfortable taking your own blood pressure, you will only need to
measure it once or twice each time.
Ask your doctor how often you should take your blood pressure. Your doctor may ask you to check your blood pressure more often if
your blood pressure is not well-controlled or if you are taking different
medicines or changing doses of a medicine.1

comfortable and relaxed. Sit quietly for at least 5 minutes with both feet on
the floor. Try not to move or talk while you are measuring your blood
- Sit with your arm slightly bent and resting comfortably
on a table so that your upper arm is on the same level as your heart.
- Place the blood pressure cuff on the skin of your upper arm. You
may have to roll up your sleeve, remove your arm from the sleeve, or take your
- Wrap the blood pressure cuff snugly around your upper arm so
that the lower edge of the cuff is about
1 in. (2.5 cm) above the bend
of your elbow.
Keeping a blood pressure
Record your blood pressure numbers with the date and time. You might use a log book or a spreadsheet on your computer. Your monitor might have a feature that will record your numbers for you. Some monitors can transfer this information to
