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 reflect 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

4

hypertensive 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.

Please note:

· Hypotension value is for reference only.

· Blood pressure is considered high when either the
diastolic or systolic blood pressure value exceeds the
normal range.

Hypertension systolic over 160
(high pressure) diastolic over 95

95

Hypertonia systolic 140-159
(Border value) diastolic 90-94

90

Hypotension Normal
(low pressure) range

systolic under 90 systolic under 139

diastolic under 89

diastolic (mmHg)

90 140 160

Systolic (mmHg)

Figure 3

· Only a physician can tell you your normal blood pressure
range and the point at which you are at risk. Consult your
physician to obtain these values. If the measurements
taken with this product fall outside the range, consult your
physician.

Why does my blood pressure fluctuate 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.
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).

detect your blood pressure. Before every measurement, the
main unit establishes a “zero pressure” equivalent to the air
pressure. 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, 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. After all readings are determined and
displayed 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).

Figure 5a Figure 5b Figure 5c

Note: Replace the batteries whenever the weak battery

) shows, the display is dim, or the display does

mark (
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 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, year month/day or day/month format, month,
date, and measurement unit (mmHg or kPa).

Note: Select the measurement unit most applicable for
your region. mmHg is used worldwide, including the
United States and most of Europe. kPa is primarily used
in the People's Republic of China.

2. Press MEM / UP to increase a value or change the
setting.

3. Press SET to accept the change and switch to the next
setting.

4. To exit the setup menu anytime, press ON.

6

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).

T AKING 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.

·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 fingers and hand while taking a
measurement. Rapid movements or other activities may alter your
reading.

·Wait at least one hour before taking your blood pressure if you
have just eaten a large meal.

·Do not smoke or drink alcohol 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.

·For a meaningful comparison, try to measure under similar
conditions. For example, take daily measurements at approximately
the same time, on the same wrist, or as directed by a physician.

·T o stop the measurement process at any time, press the ON button.

·The main unit automatically switches off 1 minute after taking a

measurement. To save the battery life, press the ON button as
soon as you are finished.

To take a measurement:

1. Choose the position you from which you wish to measure
– sitting or lying down.

2. Position your body so that your wrist is parallel with your
heart, using the chart and illustrations below as a guide.

IF you are… THEN…

3. Relax your hand.

4. Press the ON button.
Result: After a few seconds, the blood pressure monitor

beeps and begins inflating the wrist cuff. It then slowly
deflates until there is another beep, signifying that the
measurement is complete. Don’t move from the first beep
until the last to ensure a more accurate measurement.
Your systolic and diastolic pressure readings flash on the
display, followed by MAP (Mean Arterial Pressure, see
page 4) and pulse per minute readings every two
seconds. The measurement is automatically stored as
the first (1) entry in the memory; the last entry (8) is
dropped, and all the entries in between move up one
digit (e.g., 7 becomes 8, and so on).

Position your wrist on a support, cushion,
or your thigh so that it is parallel with your
heart with the palm facing up.

RECALLING MEASUREMENTS STORED IN

THE MEMORY

The memory can hold up to 8 records. The records are
automatically stored each time you take a new measurement.

Note:

· The most recent record (1) is shown first. Each new
measurement is assigned to the first (1) record. All other
records are pushed back one digit (e.g., 2 becomes 3,
and so on), and the last record (8) is dropped from the
list.

· Press MEM / UP again to see additional records.

· The date and time of measurement are shown with each

record.

· Memory records will be kept even when the batteries
are replaced.
