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
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 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 can be used to evaluate excessive 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.
Why measure your blood pressure?
Blood pressure measurement can highly refl ect one’s
health condition. High blood pressure is potentially linked
to serious illnesses such as stroke, heart disease and
kidney failure.
Since there is no symptom most of the time, many
hypertensive people do not realize they are at risk until
their health is seriously threatened.
What is the standard blood pressure classifi cation?
Figure 3 illustrates the blood Pressure classifi cation made
by World Health Organization (WHO) and International
Society of Hypertension (ISH) in 1999.
Reference material: 1999 World Health Organization-
International Society of Hypertension Guidelines for the
management of hypertension, Journal of Hypertension,
1999, 17(2): 151-183.
NOTE
• Blood pressure is considered high when either the
diastolic or systolic blood pressure value exceeds the
normal range. When a patient’s systolic and diastolic
blood pressures fall into different categories, the
higher category should apply.
• Only a physician can tell you your
normal blood
pressure range and the point at which you are at risk.
Why does my blood pressure fl uctuate throughout the day?
Individual blood pressure varies greatly both on a daily and
a seasonal or temperature basis. These variations may be
more pronounced in hypertensive patients. Normally the
blood pressure rises while at work and is at its lowest
during sleep.
The graph below illustrates the variations over a single day
with measurement taken every 5 minutes. The thick line
represents sleep time. The rises in blood pressure at 4PM
(A in the graph) and 12AM (Bin 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
This product uses the Oscillometric Measuring method to
detect your blood pressure. Before every measurement,
the unit establishes a “zero pressure”equivalent to the air
pressure.
Then it starts infl ating the wrist cuff to 180mmHg or higher
until it senses that it has blocked your blood in the artery.
After that, the defl ation process starts, during which time
the 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. After all readings are determined and
displayed on the LCD, the measurement is fi nished
and
the wrist cuff automatically defl ates.
GETTING STARTED
INSTALLING AND REPLACING THE BATTERIES
1. Slide off the battery cover.
2. Install the batteries by matching the correct polarity, as
shown below. Always use the correct battery type (2
alkaline LR03 AAA-size).
3. Replace the cover.
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.

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.
4. Position the edge of the cuff about 0.4 inches (1cm)
from the bottom of your palm.
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 not be accurate.

TAKING A BLOOD PRESSURE MEASUREMENT
You can choose to take your blood pressure while sitting or lying
down. Below are some helpful tips for taking a measurement:
• Be sure to set the clock before taking your fi rst
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 "Setting date,
time and measurement units" section.
• It is important to relax when taking 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 fi ngers and hand while
taking a measurement. Rapid movements or other
