About Blood Pressure
A. What is blood pressure?
Blood pressure is the measurement of the force of blood pushing
against the walls of the arteries. Arterial blood pressure is
constantly fluctuating during the course of the cardiac cycle. The
highest pressure in the cycle is called the systolic blood pressure,
and represents the pressure in the artery when the heart is beating.
The lowest pressure is the diastolic blood pressure, and represents
the pressure in the artery when the heart is at rest. Both the
systolic and the diastolic pressure are necessary for a physician to
evaluate the status of a patient's blood pressure.
Many factors such as physical activity, anxiety or the time of day,
can influence your blood pressure. Blood pressure is typically low
in the mornings and increases from the afternoon to the evening.
It is on average lower in the summer and higher in the winter.
B. Why is it useful to measure blood pressure
at home?
Having one's blood pressure measured by a doctor in a hospital or
a clinic, is often associated with a phenomenon called “White Coat
Hypertension” where the patient becomes nervous or anxious,
thus raising his blood pressure. There are also numerous other
factors that might cause your blood pressure to be raised at a
specific time of day. This is why medical practitioners recommend
home monitoring as it is important to get readings of blood
pressure during different times of the day to really get an idea of
your real blood pressure.
Medical practitioners generally recommend the “Rule of 3”, where
you are encouraged to take your blood pressure three times in a
row (at 3 ~ 5 minute interval), three times a day for three days.
After three days you can average all the results and this will give
you an accurate idea of what your blood pressure really is.

About Blood Pressure
A. WHO blood pressure classifications:
Standards for assessment
of high or low blood pressure
without regard to age, have
been established by the World
Health Organization (WHO),
as shown in the chart.
However this chart is not
exact for classification of blood pressure and it's intended to be
used as a guide in understanding non-invasive blood pressure
measurements. Please consult with your physician for proper
diagnosis.
B. Variations in blood pressure:
Individual blood pressures vary greatly both on a daily and a
seasonal basis. These variations are even more pronounced in
hyper tense patients. Normally the blood pressure rises while at
work and is at its lowest during sleeping period.
(hyper tense: means a person who has high blood
pressure symptom.)
The graph below illustrated the variations in blood pressure
over a whole day with measurement taken every five minutes.
The thick line
represents sleep.
The rise in blood
pressure at 4 PM (A
in the graph) and
12 AM (B in the
graph) correspond
to an attack of
pain.

Measurement Method
HL158LD Automatic Wrist Blood Pressure Monitor measures blood
pressure and heart rate by oscillometric method, meaning the
fluctuations in pressure are measured. Once the cuff is wrapped
around your wrist, just turn on the monitor and inflation
automatically starts. The inflation of the cuff creates pressure around
the arteries inside the wrist.
Within the cuff is a gauge which senses the fluctuations (oscillations)
in pressure. The fluctuation measured represents the degree of
intensity that your arteries contracting with each heart beat, and also
a result of the pressure that the cuff has placed on the wrist. The
monitor measures these contractions and converts the information to
a digital value. This is the result displayed on the monitor screen.
Once the measurement is complete, the cuff will automatically
deflate.
Note!
* The patient is an intended operator.
* The applied part is the cuff.

7
Accuracy

Features
Irregular Heartbeat Detector
The symbol will appear on screen indicating a certain
heartbeat irregularity was detected during measurement.
The heartbeat rhythm that is more than or less than 25% from the
average rhythm is usually defined as an irregular heartbeat rhythm.
Talking, moving, shaking or an irregular pulse during the
measurement can result in the appearance of this symbol.
Usually this is not a cause for concern, however if the symbol
appears often, we recommend you seek medical advice.
And please note that the device does not replace a cardiac
examination, but serves to detect pulse irregularities at an early
stage.
*Note ！
The pulse display is not suitable for checking the frequency of heart
pacemakers. If a certain pulse irregularity is detected during measurement
often, we recommend you seek medical advice.
As a safeguard, we recommend that if you have arrhythmias such as atrial or
ventricular premature beats and atrial fibrillation or any other special
conditions you should check with your physician before using your device.
The IHB function is not designed for use by people with arrhythmias nor for
diagnosing or treating an arrhythmic problem. In order to filter the unstable
status of user and avoid affecting the detection of heart rate from any
movement, shaking or talking in the beginning of measurement, the method of
averaging heart beat intervals of subject device is calculated with the three
proper heart beat pulses detected in the beginning of measurement and that is
different from a strict mathematical averaging of all recorded intervals.
At least 3 beats with at least 25 % difference from the average heart beat
interval will generate the IHB icon on the screen.
