You are not to use the information contained herein, or this product
for diagnosing or treating a health problem or prescribing any
medication. If you have or suspect that you have a medical problem,
promptly consult your healthcare provider.
Intended Use
This device uses the oscillometric method to automatically measure
systolic and diastolic blood pressure as well as heart rate.
The measurement position is at human being’s arm.
All values can be read out in the LCD panel. Measurement position is
at human being’s upper arm. The intended user of this
over-the-counter device is adults aged 18 years and older with arm
circumference ranging from 9 inches to 1 inches (approx.23 cm to
43 cm) for home use.
HL858DM features BP Category Indicator that will show the
information with the readings on the screen for the user tracking their
blood pressure level.
HL858DM is equipped with an Advanced IHB (Irregular heartbeat)
detection feature to collect and analyze pulses. If the specific
irregular heartbeats are detected and it may affect blood pressure
reading with deviation, the device will give the user a warning signal.
The feature can inform the user that the measured blood pressure
reading may be inaccurate once the specific irregular heartbeats are
detected.
Besides, the device features a built-in "Bluetooth Transmission"
function, which enables the device automatically transmit measuring
results to paired Bluetooth-enabled device. Also, users could simply
synchronize the current date and time, and check the battery status
of blood pressure monitor by means of DailyChek
®
application software
with
the paired Bluetooth-enabled device.

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. AHA blood pressure classifications:
Standards for assessment of high or low blood pressure without
regard to age, have been established by the American Heart
Association (AHA 201 ), as shown in the below chart.
BLOOD PRESSURE CATEGORY
SYSTOLIC mm Hg
(upper number)
DIASTOLIC mmHg
(lower number)
NORMAL LESS THAN 120 and LESS THAN 80
ELEVATED 120-129 and LESS THAN 80
HIGH BLOOD PRESSURE
(HYPERTENSION)STAGE 1
130-139 or 80-89
HIGH BLOOD PRESSURE
(HYPERTENSION)STAGE 2
140 OR HIGHER or 90 OR HIGHER
HYPERTENSIVE CRISIS
(consult your doctor immediately)
HIGNER THAN 180 or HIGHER THAN 120
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: eans a person who has high blood
pressure sy pto .)
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.
