Introduction
What is blood pressure?
Your heart acts as a pump to circulate blood around
your body and help supply it with oxygen. Blood
pressure is the force needed for the heart to push
blood through the arteries. The highest pressure in this
cycle is when the heart contracts, this is called the
SYSTOLIC BLOOD PRESSURE. Between contractions,
the heart relaxes and blood flows into it since it is at
its lowest pressure, which is called DIASTOLIC BLOOD
PRESSURE.
Both blood pressure measurements, the systolic and
diastolic, are necessary to enable a doctor to evaluate
the status of a patient’s blood pressure.
Many factors such as physical activity, anxiety, or simply the
time of day, can influence your blood pressure.
Drinking caeine (in tea or coee) can also temporarily raise
your blood pressure, as can the nicotine in cigarettes.
Blood pressure can also follow a daily pattern, varying from
minute to minute and typically being at its lowest while we
are asleep. These variations are even more pronounced in
patients with high blood pressure.
Blood pressure is measured in millimetres of mercury (mmHg)
and measurements are written with the systolic pressure
before the diastolic e.g. a blood pressure written as 120/80 is
referred to as 120 over 80.

Pulse Rate
This blood pressure monitor also measures your pulse rate.
Your pulse reflects your heart rate and is measured in terms
of the numbers of beats per minute. Pulse rate varies from
minute to minute, and is aected by many things, including
exercise, stress, anxiety, certain medicines and some foods.
Why is it beneficial to measure your blood pressure
at home?
Monitoring your blood pressure at home gives you the
advantage of taking blood pressure measurements at fixed
times of the day, in familiar surroundings, without external
influences. As a variety of conditions aect blood pressure,
a single measurement is not sucient for an accurate
diagnosis. Home monitoring enables measurements to be
taken over the course of weeks and helps to identify an
ongoing trend.
Here are a few tips to help you obtain more accurate
measurements:
Blood pressure changes with every heartbeat and varies
throughout the day. The measurements that you obtain from
this blood pressure monitor will dier as a result.
•Blood pressure recording can be aected by the position of
the user, his or her physiological condition and other
factors. For greatest accuracy, wait one hour after
exercising, bathing, eating, drinking beverages with alcohol
or caeine, or smoking to measure blood pressure.
•Before measurement, it’s suggested that you sit quietly for
at least 5 minutes as measurement taken during a relaxed
state will have greater accuracy. You should not be
physically tired or exhausted while taking a measurement.
•
Do not take measurements if you are under stress or tension.
•During measurement, do not talk or move your arm or hand
muscles.
•Take your blood pressure at normal body temperature.
If you are feeling cold or hot, wait a while before taking a
measurement.
•If the monitor is stored at very low temperature (near
freezing), have it placed at a warm location for at least one
hour before using it.
•Wait 5 minutes before taking the next measurement.

Accreditation
This unit has been validated in accordance with requirements
set by the European Society of Hypertension (ESH). This
protocol tests the accuracy of blood pressure monitors to
ensure measurements are comparable to those obtained by
trained medical professionals
Comfort Inflation Technology
The unit will only inflate as high as necessary to provide
greater comfort. It uses the oscillometric method to detect
your blood pressure. Before the custarts inflating, the
device will establish a baseline cupressure equivalent to
the air pressure. This unit will determine the appropriate
inflation level based on pressure oscillations, followed by
cudeflation. During the deflation of the wrist cu, the
monitor is detecting the pressure oscillations generated by
the beat-to-beat pulsatile. Any muscle movement during this
period of time will cause measurement error. After detecting
the amplitude and the slope of the pressure oscillations
during the deflation process, your S150 will determine for
you the systolic and diastolic pressures, and your pulse rate
is detected at the same time.
During the deflation, the device will detect the amplitude
and slope of the pressure oscillations and thereby determine
for you the systolic blood pressure, diastolic blood pressure,
and pulse.

Hypertension Risk
Hypertension can be classified into 4 stages
1
.
Systolic
Pressure
Diastolic
Pressure
Normal <120 And <80
Suspected Hypertension 120~139 Or 80~89
Suspected
Stage 1 hypertension
140~159 Or 90~99
Suspected
Stage 2 hypertension
≥160 Or ≥100
These blood pressure classifications are based on historical
data, and may not be directly applicable to any particular
patient. It is important that you consult with your physician
regularly. Your physician will tell you your normal blood pressure
range as well as the point at which you will be considered at
risk. For reliable monitoring and reference of blood pressure,
keeping long-term records is recommended.
1As defined by The United States National High Blood Pressure Education Program
Coordinating Committee (7th report of the Joint National Committee on Prevention,
Detection, Evaluation, and Treatment of High Blood Pressure-Complete Report
JNC-7, 2003).
Applying the Cu
1. Remove all watches, jewellery,
etc. prior to attaching the wrist
monitor. Clothing sleeves should
be rolled up and the cushould be
wrapped on bare skin for correct
measurements.
2. Apply the cuto your left wrist
with your palm facing up as shown
in fig. 1.
3. Make sure the edge of the cu
is about 1 cm from the palm as
shown in fig. 2.
4. In order to ensure accurate
measurements, fasten the velcro
strap securely around your wrist
so there is no extra space between
the cuand the wrist as shown
in fig. 3. If the cuis not wrapped
tight enough, the measurement
values may be inaccurate.
5. If your physician has diagnosed
you with poor circulation in your
left arm, carefully place the cu
around your right wrist as shown
in fig. 4.

Correct Measuring Posture
1. Place your elbow on a table so
that the cuis at the same level
as your heart as shown in fig. 5.
Note: Your heart is located slightly
below your armpit and slightly to
the left of the middle of your chest.
Relax your entire body, especially
the area between your elbow and
fingers.
2. If the cuis not at the same
level as your heart or if you can
not keep your arm completely still
throughout the measurement,
use a soft object such as a folded
towel to support your arm as fig. 6.
Do not allow hard objects to come
in contact with the wrist cu.
3. Turn your palm upwards.
4. Sit upright in a chair, and take
5-6 deep breaths. Avoid leaning
back while the measurement is
being taken as fig. 7.
Measurement Procedures
1. Press the ON/OFF/START button. All digits will light up,
checking the display functions. The checking procedure
will complete in 2 seconds.
2. After all symbols appear, the display will show a flashing
“0”. At this time, the monitor is ready to measure.
3. The monitor will automatically inflate to approximately 180
mmHg and measurement will begin.
4. When the measurement is completed, systolic blood
pressure, diastolic blood pressure, and pulse will be
shown simultaneously and be saved automatically in the
memory system.
Press the ON/OFF/START button to turn the monitor o. If
no button is pressed, the monitor will automatically shut o
after 1 minute.
This monitor will re-inflate automatically to approximately
220 mmHg if the system detects that your body needs more
pressure to measure your blood pressure.
Note:
1. To interrupt the measurement, simply press ON/OFF/START
button or Memory button; the cuwill deflate immediately.
2. During the measurement, do not talk or move your arm or
hand muscles.
