ABOUT BLOOD PRESSURE
Whatis blood pressure?
Blood pressure is the force generated by the blood against
thewalls ofarteries duringcardiac contraction andrelaxation
(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
pressure in the cycle is known as systolic pressure. 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
andexpansive forcesacting on thearterial wallwhen thereis
no distension outward or inward. MAP is an excellent way to
evaluate the stress on the walls of your blood vessels, and
canbeused toevaluate excessiveloadon thecardiovascular
system. Show your MAP history to your doctor to provide
additional information that may help him or her understand
your situation.
Whymeasureyour blood pressure?
Blood pressure measurement can highly reflect one’s health
condition.High blood pressureis potentiallylinked to serious
illnesses such as stroke, heart disease and kidney failure.
Sincethereisnosymptommostofthetime,manyhypertensive

people do not realize they are at risk until their health is
seriously threatened.
What is the standard blood pressure classification?
The following chart (Figure 3) was taken from the World
Health Organization (WHO), and describes the various
classifications.
Pleasenote:
·Hypotension value is for reference only.
·Bloodpressureisconsideredhighwheneitherthediastolic
or systolic blood pressure value exceeds the normal
range.
·Onlya physician can tellyou your normalblood pressure
rangeand the pointat which youare at risk.Consult your
physician to obtain these values. If the measurements
taken with this product fall outside the range, consult
your physician.
Whydoesmybloodpressurefluctuatethroughout theday?
Individual blood pressure varies greatly both on a daily and a
seasonalortemperaturebasis. Thesevariationsmaybemore
pronounced in hypertensive patients. Normally the blood
pressure rises while at work and is at its lowest during sleep.
Figure4 belowillustrates thevariations overasingle daywith
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).

main unit establishes a “zero pressure” equivalent to the air
pressure.Then itstarts inflating thewrist cuffto 180mmHgor
higher until it senses that it has blocked your blood in the
artery. After that, the deflation process starts, during which
time the main unit detects pressure oscillations generated
by beat-to-beat pulsatile, which is used to determine the
systolic, mean and diastolic pressure, and also your pulse
rate. Any motion during this period will result in an incorrect
measurement.Afterallreadingsaredeterminedanddisplayed
on LCD, the measurement is finished and the wrist cuff
automatically deflates.
GETTING STARTED
Installing and replacing the batteries
To install the batteries:
1. Slide off the battery cover (Figure 5a).
2. Install the batteries by matching the correct polarity, as
shown by Figure 5b. Always use the correct battery type
(2 Alkaline LR03 AAA-size).
3. Replace the cover (Figure 5c).
Note: Replace the batteries whenever the weak battery
mark ( ) shows, the display is dim, or the display 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.
Contactyour localwaste disposalauthority forinstructions
on how to dispose of used batteries. Used batteries can
be harmful to the environment, and should not be thrown
out with household trash.
Setting the date, time, and measurement units
It is important to set the clock before using your blood
pressure monitor, so that a time stamp can be assigned to
each record that is stored in the memory.
To set the date, time, and measurement unit:
1. Press and hold SET for 2 seconds to enter the setting
mode.
The setting order is as follows: 12/24 hour format, hour,
minute, month/day or day/month format, month, date,
andmeasurement unit (mmHgor kPa).
2. Press to increase a value or change the setting.
3. Press SET to accept the change and switch to the next
setting.
4. When you are finished, press ON to exit the setup menu.

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).
