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.

Measurement Method
HL858DM 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.
* The applied part is the cuff.

Accuracy
HL858DM Automatic Upper Arm Blood Pressure Monitor has been
clinically tested against a scientific device called mercury
sphygmomanometer, considered the gold standard in blood pressure
measurement.
All HL858DM Automatic Upper Arm Blood Pressure Monitors have
performed equivalent to measurements taken with this scientific
device and are within the accuracy limits prescribed by the American
National Standard for Electronic or Automated Sphygmomano-
meters.
The SPHYGMOMANOMETER was clinically investigated according to
the requirements of ISO 81060-2:2018.

Precautions
 For those who have had a mastectomy or lymph node clearance, it
is recommended to take a measurement on the unaffected side.
 When used among medical electronic equipment on the same limb,
pressurization of the cuff may cause temporarily malfunction to
other devices.
 Keep in mind that blood pressure naturally varies from time to time
throughout the day and is affected by lots of different factors such
as stress, eating, smoking, alcohol consumption, medication, and
physical activity, etc.
 Normally the blood pressure rises while at work and is at its lowest
during sleeping period.
 Blood pressure measurements should be interpreted by a
physician or a trained health professional who is familiar with your
medical history. Using the unit and recording the results regularly
for your physician to interpret, you will keep your physician
informed of the continuing changes in your blood pressure.
 If you have one of the circulatory problems as arteriosclerosis,
diabetes, liver disease, kidney disease, severe hypertension,
peripheral circulation……, please consult your healthcare
professional before using the device.
 Results are not intended for direct diagnosis. Please consult with a
physician if you have any questions or concerns about your results.
 Blood pressure measurements taken with this device are
equivalent to those obtained by a trained observer using the cuff /
stethoscope auscultation method and are within the accuracy
limits prescribed by the Standard of EN 1060-4.
 If the cuff is worn incorrectly, or the shape of the upper arm is
special (for example, the circumference of the upper arm differs
largely from the circumference of the forearm), excessive gap
might occur between the arm cuff and the arm, and it might lead to
measurement errors or inaccuracies. If you have any question
about the condition of cuff wearing and/or measurement result,
please consult your healthcare professional.
 The applied part is cuff.
