HL858CG automatically measures human’s Systolic, Diastolic blood
pressure and heart rate by using the oscillometric method during
inflation. All values can be read out in one LCD panel. Measurement
position is at human being’s upper arm. The intended use of this
over-the-counter device is for adults aged 18 years and older with arm
circumference ranging from 9 inches to 17 inches (approx.23 cm to 43
cm) and for home use.
HL858CG detects the appearance of irregular heartbeats during
measurement; an indicated symbol will appear with measuring
reading. And the Risk Category Indicator will show the information
with the readings on the screen for the user tracking their blood
pressure level.

About Blood Pressure
1. 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.
2. 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 an event 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 physician 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 physicians 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. Standards for assessment of high or low blood pressure
without regard to age, have been established by the WHO,
and classifications adapted from JNC7:
WHO: World Health Organization
JNC 7: The Seventh Report of the Joint National Committee on
Prevention, Detection, Evaluation, and Treatment of High Blood
Pressure. NIH Publication No.04-5230 August 2004
However the above 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 PM (B in the graph) correspond to an attack of
pain.

Measurement Method
HL858CG Automatic Upper Arm 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 upper arm, just turn on the monitor and inflation
automatically starts. The inflation of the cuff creates pressure around
the arteries inside upper arm.
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 upper arm. 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.
*Theappliedpartisthe cuff.

Features
For adults 18 and older who are not on medicine for high blood
pressure, are not having a short-term serious illness, and do not
have other conditions, such as diabetes and kidney disease. To
determine category of risk when systolic and diastolic readings fall
into two areas, use the higher of the two numbers for classification.
There is an exception to the above definition of high blood pressure
for people with diabetes and chronic kidney disease. A blood
pressure of 130/80 mmHg or higher is considered high blood
pressure for those individuals.
*Note !
The above table 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.
Usually this is not a cause for concern; however we recommend you consult
with your physician for proper diagnosis or seek medical advice. Please note
that the device does not appropriate to diagnose hypertension, and it is only
for user reference on blood pressure monitoring.

Features
 Rest Assure Function
Before measurement, it is suggested that you sit quietly for 5 minutes before
measurement as measurements taken in a relaxed state according to JNC7
report to have a greater accuracy.
HL858CG provides users a helpful countdown function (REST ASSURE on/off
switch) for 5 minutes before the measurement that helps users to get
accurate results. To turn this feature OFF, slide the switch on the back to the
OFF position.
JNC7: The Seventh Report of the Joint National Committee on
Prevention, Detection, Evaluation, and Treatment of High Blood
Pressure. NIH Publication No.04-5230 August 2004
 Triple-Check (Multi-Read) Function
The Triple-Check (Multi-Read) Function automatically takes and averages 3
readings in a row, with 1 minute rest intervals in between each measurement.
To deactivate this feature and take only a single reading, slide the switch on
the back to the OFF position.

17
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
pacemarkers. 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.
