When should I check my blood pressure?
Follow your
doctor's instructions for when and how often to check your blood
pressure. Keep in mind that certain factors can cause blood
pressure to temporarily rise. Blood pressure normally rises as a
result of:
- Stress
- Smoking
- Cold temperatures
- Exercise
- A full stomach
- Full bladder
- Caffeine
- Certain medicines
Avoid any of these factors you can when taking your blood
pressure. Also try measuring your blood pressure at about the same
time each day.
Before taking your blood pressure
- Find a quiet place. You will need to listen for your
heartbeat.
- Roll up the sleeve on your left arm or remove any tight-sleeved
clothing, if needed. (It's best to take your blood pressure from
your left arm, if possible.)
- Rest in a chair next to a table for 5 to 10 minutes. (Your left
arm should rest comfortably at heart level.)
- Sit up straight with your back against the chair, legs
uncrossed.
- Rest your forearm on the table with the palm of your hand
facing up.
Taking your blood pressure
If you purchase a manual
or digital blood pressure monitor (sphygmomanometer), follow the
instruction booklet carefully. The following steps provide an
overview of how to take your blood pressure on either a manual or
digital blood pressure monitor.
1. Locate your pulse
Locate your pulse by lightly
pressing your index and middle fingers slightly to the inside
center of the bend of your elbow. Here you can feel the pulse of
the brachial artery. If you cannot locate your pulse, place the
head of the stethoscope (on a manual monitor) or the arm cuff (on a
digital monitor) in the same general area.
2. Secure the cuff
- Thread the cuff end through the metal loop and slide the cuff
onto your arm, making sure that the stethoscope head is over the
artery (when using a manual monitor.) The cuff may be marked with
an arrow to show the location of the stethoscope head. The lower
edge of the cuff should be about 1 inch above the bend of your
elbow. Use the Velcro® wrap to make the cuff snug,
but not too tight.
- Place the stethoscope in your ears. Tilt the ear pieces
slightly forward to get the best sound.
3. Inflate and deflate the cuff
you are using a manual monitor:
- Hold the pressure gauge in your left hand and the bulb in your
right. (As shown to the right.)
- Close the airflow valve on the bulb by turning the screw
clockwise.
- Inflate the cuff by squeezing the bulb with your right hand.
You may hear your pulse in the stethoscope.
- Watch the gauge. Keep inflating the cuff until the gauge reads
about 30 points (mm Hg) above your expected systolic
pressure. At this point, you should not hear your pulse in the
stethoscope.
- Keeping your eyes on the gauge, slowly release the pressure in
the cuff by opening the airflow valve counter clockwise. The gauge
should fall only 2 to 3 points with each heartbeat. (You may need
to practice turning the valve slowly.)
- Listen carefully for the first pulse beat. As soon as you hear
it, note the reading on the gauge. This reading is your
systolic pressure.
- Continue to slowly deflate the cuff.
- Listen carefully until the sound disappears. As soon as you can
no longer hear your pulse beat, note the reading on the gauge. This
reading is your diastolic pressure.
- Allow the cuff to completely deflate.
