ABOUT BLOOD PRESSURE
What is blood pressure?
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
pressureinthe 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
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
canbeusedtoevaluateexcessiveloadonthecardiovascular
system. Show your MAP history to your doctor to provide
additional information that may help him or her understand
your situation.
Whymeasureyour bloodpressure?
Blood pressure measurement can highly reflect one’s health
condition. High blood pressure is potentially linked to serious
illnessessuchasstroke,heart diseaseandkidneyfailure.Since
there is no symptom most of the time, many hypertensive

Why does my blood pressure fluctuate throughout the
day?
Individual blood pressure varies greatly both on a daily and a
seasonalortemperaturebasis.Thesevariations may be more
pronounced in hypertensive patients. Normally the blood
pressure rises while at work and is at its lowest during sleep.
Figure 4 below illustrates the variations over 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 THE BLOOD PRESSURE MONITOR
WORKS
ThisproductusestheOscillometricMeasuringmethodtodetect
yourbloodpressure.Before everymeasurement,themain unit
establishesa“zeropressure”equivalenttotheairpressure.Then
it starts inflating the wrist cuff to 180mmHg or higher until it
senses that it has blocked your blood in the artery. After that,
people do not realize they are at risk until their health is
seriouslythreatened.
What is the standard blood pressure classification?
Thefollowingchart(Figure 3) wastakenfromtheWorld Health
Organization(WHO),and describesthevariousclassifications.
NOTE
·Hypotension value is for reference only.
·Bloodpressureisconsideredhighwheneitherthediastolic
orsystolicbloodpressurevalueexceedsthenormalrange.
·Only a physician can tell you your normal blood pressure
range and the point at which you are at risk. Consult your

POSITIONING THE WRIST CUFF
It is important to properly position the wrist cuff to ensure that you receive an accurate reading.
1. Removeallaccessories(watch,bracelet,etc.)fromyourleftwrist.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 lying down.
HELPFUL TIPS FOR TAKING A MEASUREMENT:
·Be sure to set the clock before taking your first
measurement, or whenever you replace the batteries,
so that the date and time are stored in the memory
with your history. For instructions, refer to page 6.
·Itisimportant torelaxwhentakingyour bloodpressure.
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.
·Waitatleastonehourbeforetakingyour bloodpressure
if you have just eaten a large meal.
·Donotsmokeordrinkalcohol before taking 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.
