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 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 PM (B in the graph) correspond to an attack
of pain.

Measurement Method
HL158HD 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.
Accuracy
HL158HD Automatic Wrist Blood Pressure Monitor has been clinically
tested against a scientific device called a mercury
sphygmomanometer, considered the gold standard in blood pressure
measurement.
All HL158HD Automatic Wrist 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
Sphygmomanometers.
*We suggest our users
have their blood pressure monitor
checked every 2 years. T
his operation should only be
performed by Manufacturer or by authorized representatives.

Precautions
* Do not use this manual and product as a substitute for advice,
diagnosing or treating a health problem or prescribing any
medication by your doctor. If you have a medical problem,
promptly consult your healthcare provider.
* Read the Instruction Manual thoroughly before measuring and
keep it at hand for your reference at any time.
* This device uses the oscillometric method to measure systolic
and diastolic blood pressure as well as your heart rate. It’s
recommended for use by people over the age of 18 and not to be
used on infant or children.
* The device is designed for home use and not suitable for clinical
use.
Do not take a measurement in a low (less than 41 ℉/5 ℃) and
high (more than 104 ℉/40 ℃) temperature, nor in a place outside
humidity ranges (15% ~ 93% R.H.), or you may get inaccurate
readings.
Wait 30 ~ 45 minutes before measurement if you’ve just
consumed caffeinated beverages or smoked cigarettes.
Rest at least 5 ~ 10 minutes before taking a measurement.
To allow your blood vessels to return to the condition prior to
taking the measurement, please wait at least 3 ~ 5 minutes in
between measurements. You may need to adjust the wait time
according to your personal physiological situation.
We recommend you using the same wrist (preferably the left wrist)
and measuring around the same time each day.
Sit down comfortably and place your elbow on the table with your
feet flat on the floor. Please do not cross your legs during
measurements.
Keep the device at heart level. Relax your hand with the palm
facing up.
Perform measurements in a quiet and relaxed environment at
room temperature.
Do not move or shake the device during a measurement. Please
keep quiet and do not talk during measurements.
Proper cuff size is critical for accurate measurements. Follow the
instructions in this manual and printed on the cuff to ensure the
appropriate size of cuff is being used.

Precautions
Keep in mind that blood pressure naturally varies from time to
time through out 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.
This product is not suitable for people with arrhythmias and
pregnant women.
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 American National Standard for Manual,
electronic, or Automated Sphygmomanometers.
*Attention
！
1. Do not use the device on infants, children, or those who cannot express their
own intention.
2. The device is equipped with sensitive electronic components. While
measuring, avoid strong electrical or electromagnetic fields, e.g. mobile
phones, microwave ovens, etc; or it may lead to temporary reading error or
inaccuracy.
3. Consider the electromagnetic compatibility of the device (ex. power
