ABOUT BLOOD PRESSURE
Whatisbloodpressure?
Blood pressure is the force generated by the blood against
the walls of arteries during cardiac contraction and relaxation
(e.g., the pumping action of the heart).
What are systolic pressure and diastolic pressure?
When ventricles contract and pump blood out of the heart,
blood pressure reaches its maximum value. This highest
pressurein the cycle is known as systolicpressure. When the
heart relaxes between heartbeats, the lowest blood pressure
is diastolic pressure.
What is mean arterial pressure (MAP)?
The mean arterial pressure (MAP) is the average pressure
that forces blood through the arteries. It is not the average of
the systolic and diastolic blood pressure; rather, MAP
corresponds to a state of balance between the compressive
and expansive forces acting on the arterial wall when there is
no distension outward or inward. MAP is an excellent way to
evaluate the stress on the walls of your blood vessels, and
canbe usedto evaluateexcessive load on the cardiovascular
system. Show your MAP history to your doctor to provide
additional information that may help him or her understand
your situation.
Whymeasureyourbloodpressure?
Blood pressure measurement can highly reflect one’s health
condition. High blood pressure is potentially linked to serious
illnesses such as stroke, heart disease and kidney failure.
Sincethereisnosymptommostofthetime,manyhypertensive

GB
people do not realize they are at risk until their health is
seriously threatened.
What is the standard blood pressure classification?
Thefollowingchart(Figure 3) wastakenfrom the WorldHealth
Organization(WHO),anddescribesthevariousclassifications.
Pleasenote:
· Hypotension value is for reference only.
· Bloodpressure is considered high when either thediastolic
orsystolic blood pressurevalue exceedsthe normalrange.
· Only a physician can tell you your normal blood pressure
range and the point at which you are at risk. Consult your
physiciantoobtainthesevalues.Ifthe measurements taken
withthisproductfalloutsidetherange,consultyourphysician.
Whydoes my bloodpressurefluctuate throughouttheday?
Individual blood pressure varies greatly both on a daily and a
seasonalortemperature basis.These variations maybe more
pronounced in hypertensive patients. Normally the blood
pressure rises while at work and is at its lowest during sleep.
Figure4 below illustrates the variationsover a single day with
measurement taken every five minutes. The thick line
represents sleep time. The rises in blood pressure at 4 PM (A
in the graph) and 12AM (B in the graph) correspond to an
attack of pain and sexual intercourse (Beven, Honour &
Stott, Clin. Sci. 36:329, 1969).
HOW DOESTHE BLOOD PRESSURE

AAA
Note: Replacethe batterieswhenever theweak battery
mark( ) shows, the display is dim, or thedisplay does
not illuminate when the power is on. Replace all the
batteries at the same time – it is dangerous to mix old
and new batteries.
Contact your local waste disposal authority for
instructions on how to dispose of used batteries. Used
batteriescan beharmful tothe environment, and should
not be thrown out with household trash.
Setting the date, time, and measurement unit

Positioning the wrist cuff
It is important to properly position the wrist cuff to ensure that you receive an accurate reading.
1. Remove all accessories (watch, bracelet, etc.) from your left wrist. If your physician has diagnosed you with poor
circulation in your left arm, use your right wrist.
2. Roll or push up your sleeve to expose the skin.
3. Apply the cuff to your left wrist with your palm facing up (Figure 6a).
4. Position the edge of the cuff about 1 centimeter from the bottom of your palm (Figure 6b).
5. Fasten the wrist cuff around your wrist, leaving no extra room between the cuff and your skin. If the cuff is too loose, the
measurement will be inaccurate (Figures 6c – 6d).

TAKING A BLOOD PRESSURE
MEASUREMENT
You can choose to take your blood pressure while sitting or
lyingdown.
HelpfulTips for taking a measurement:
· Be sure to set the clock before taking your first
measurement,or whenever you replace thebatteries,
so that the date and time are stored in the memory
with your history. For instructions, refer to page 6.
· Itisimportanttorelaxwhentaking your blood pressure.
Try to take a 15-minute rest before you begin.
· Do not lean backward or bend your wrist inward while
taking a measurement.
· Avoid talking or moving your fingers and hand while
taking a measurement. Rapid movements or other
activities may alter your reading.
· Waitatleastone hourbeforetakingyourbloodpressure
if you have just eaten a large meal.
· Donotsmoke ordrink alcohol beforetaking your blood
pressure.
· Do not measure your blood pressure if you are under
stress.
· Wait at least 3 minutes between measurements. This
allows your blood circulation to recover.
· For a meaningful comparison, try to measure under
similar conditions. For example, take daily
measurementsatapproximately thesame time, onthe
same wrist, or as directed by a physician.
· To stop the measurement process at any time, press
the ON button.
.Themain unit automaticallyswitches off1 minuteafter
takinga measurement.
. To save the battery life, press the ON button as soon
as you are finished.
