safe place

.

Important information

●

Refer to the following sections to learn about important safety instructions and how to take
care of the product.

● Safety information

•Self-measurement means control, not diagnosis or treatment. Your values must always be
discussed with your doctor or a physician who is familiar with your family history.

•If you are undergoing medical treatment and receiving
medication, consult your doctor to determine the most
appropriate time to measure your blood pressure. Never
alter the dosages of any medication without direction
from your doctor.

•Your blood pressure depends on several factors, such as age, gender, weight, and physical
condition. It also depends on the environment and your state of mind at the time of
measurement. In general, your blood pressure is lower when you are asleep and higher
when you are active. Your blood pressure may be higher when recorded at a hospital or a
clinic and may be lower when measured in the relaxing comfort of your home. Due to these
variations, we recommend that you record your blood pressure regularly at home as well as
at your doctor’s clinic.

•Try to record your blood pressure regularly at the same time of the day and under the same
conditions. This will help your physician detect any extreme variations in your blood pressure
and thus treat you accordingly. The ideal time to measure your blood pressure is in the
morning just after you wake up before breakfast and any physical activity, and in the absence
of the urge to urinate. If this is not possible, try to take the measurements later in the
morning, before you start any physical activity. Relax for a few minutes before you record
your blood pressure.

•Your blood pressure increases or decreases under the following circumstances.
Blood pressure is higher than normal:

—when you are excited, nervous, or tense
—while taking a bath
— during and after exercise or strenuous physical activity
— when it is cold
—within one hour after meals
— after drinking tea, coffee, or other caffeinated drinks
— after smoking tobacco
—when your bladder is full

•Blood pressure is lower than normal:
— after consuming alcohol

—after taking a bath

•Blood pressure measurements determined with this device are equivalent to those obtained
by a trained observer using the cuff/stethoscope auscultation method, within the limits
prescribed by the American National Standard.

This device is validated against Korotkoff phase I and V for Systolic and Diastolic pressure.

•The pulse display is not suitable for checking the frequency of heart pacemakers.

•If you have been diagnosed with a severe arrhythmia or irregular heartbeat, vascular
constriction, liver disorders, or diabetes, have a cardiac pacemaker, or are pregnant,
measurements made with this instrument should only be evaluated after consultation with
your doctor.

• This product has been designed for adult usage frome 12 years on Consult with a

About blood pressure

●

Your blood pressure level is determined in the

circulatory center of your brain. Your nervous

system allows your body to adapt or alter blood
pressure in response to different situations. Your
body alters your pulse or heart rate and the width
of blood vessels through changes in muscles in the
walls of blood vessels.
Your blood pressure reading is highest when your
heart pumps or ejects blood. This stage is called your Systolic blood pressure.
Your blood pressure is lowest when the heart rests (in-between beats). This is called your
Diastolic blood pressure.

●

It is critical to maintain blood pressure values within a “normal” range in order to prevent
cardiovascular diseases. Increased blood pressure values (various forms of hypertension)
have associated long- and medium-term health risks. These risks concern the arterial blood
vessels of your body, which are endangered due to constriction caused by deposits in the
vessel walls (arteriosclerosis). A deficient supply of blood to important organs (heart, brain,
muscles) can be the result. Furthermore, with long-term increased blood pressure values,
the heart will become structurally damaged.
There are many different causes of the appearance of high blood pressure. We differentiate
between common primary (essential) hypertension, and secondary hypertension. The latter
group can be ascribed to specific organic malfunctions. Please consult your doctor for
information about the possible origins of your own increased blood pressure values.

Normal blood pressure values

●

Blood pressure is too high when, at rest, the diastolic pressure is above 90 mmHg or the
systolic blood pressure is over 140 mmHg.

●

If you obtain readings in this range, consult your doctor immediately. High blood pressure
values over time can damage blood vessels, vital organs such as the kidney, and your heart.

●

Should the systolic blood pressure values lie between 140 mmHg and 160 mmHg or the
diastolic blood pressure values lie between 90 mmHg and 95 mmHg, likewise, consult your
doctor. Regular self-checks will be necessary.

●

With blood pressure values that are too low (i.e., systolic values under 105 mmHg or
diastolic values under 60 mmHg), consult with your doctor.

●

Even with normal blood pressure values, a regular self-check with your blood pressure
monitor is recommended. In this way you can detect possible changes in your values early
and react appropriately.

Further information

● If your values are mostly "normal” under resting conditions but exceptionally high

under conditions of physical or psychological stress, it is possible that you are
suffering from so-called ”labile hypertension”. In any case, please discuss the values
with your doctor.

● Correctly measured diastolic blood-pressure values above 120mmHg require

immediate medical treatment.

USING THE DEVICE

USING THE DEVICE

●

This section describes how to get the maximum benefit from your BP3AD1 blood pressure
monitor. Follow the instructions carefully to get an accurate measurement of your blood
pressure and pulse rate.

Setting the date and time

When you insert the batteries for the first time (see
“Inserting the batteries”), the BP3AD1 prompts you to set
the current date and time. You can also adjust the date
and time at any time by pressing and holding down the
time button for over 3 seconds. Follow these steps to set
the date and time:

When you replace the batteries, the LCD screen

starts flashing the current year setting. Press the
memory button repeatedly to adjust the year and

then press the time button to confirm the setting.

Next, the screen starts flashing the month and date
setting. Press the memory button repeatedly to set
the month and date, and then press the time button
to confirm the settings.

Lastly, the screen starts flashing the hour and minute
values. Press the memory button repeatedly to set
the hour and minutes and then press the time button
to confirm the settings.

Obtaining accurate measurements

Your blood pressure can vary based on numerous factors, physiological conditions, and your
surroundings. Follow these guidelines to obtain accurate and error-free measurements of
your blood pressure and pulse rate.

Before measuring

●

Avoid eating, smoking as well as all forms of exertion directly before the measurement. All
these factors influence the measurement result. Relax by sitting in an armchair in a quiet
atmosphere for about 5 minutes before the measurement.

●

Always take measurements on the same arm (normally left) and in the same posture. Do not
switch between right and left arms while recording your blood
pressure as there may be a difference of up to
10mmHg pressure between the two arms.

●

Attempt to carry out the measurements regularly at the
same time of day, since blood pressure changes during the
course of the day. The ideal time to measure your blood
pressure is in the morning after you wake up, before
breakfast and physical activity, and in the absence of the
urge to urinate.

●

Rest for 5 minutes sitting quietly and release all the
tension in your body — specially the arm muscles —
before beginning with the measurement. Remain calm and quiet when the measurement is in
process. Do not speak or move your arm (as well as other body) muscles during the process.

Common sources of errors

●

All efforts by the patient to support the arm can increase the blood pressure. Make sure you

are in a comfortable, relaxed position and do not activate any of the muscles in the
measurement arm during the measurement. Use a cushion for support if necessary.

Attention!
Comparable blood pressure measurements always require the same conditions with a
peaceful and calm environment. Ensure that you take measurements under the same
conditions to obtain an accurate estimate of blood pressure variation patterns.

●

If the arm artery lies considerably lower or higher than the heart, an erroneous value of blood
pressure is measured. Each 15 cm difference in height results in a measurement error of 10
mmHg.

●

A loose cuff causes false measurement values.

●

With repeated measurements, blood accumulates in the arm, which can lead to false results.
Consecutive blood pressure measurements should be repeated after at least a 15 second
pause or after the arm has been held up in order to allow the accumulated blood to flow away.

Fitting the cuff

Follow the instructions on the cuff and those described below to fit the cuff around your upper
arm correctly.

Remove all jewelry and/or thick clothing from your upper
arm and draw the cuff over the arm.

Maintain a distance of approximately 2 ~ 3 cm (1/2 in.)
between the cuff and the crook of your
elbow.

Secure the cuff with the Velcro fastener so that it is
comfortable and not too tight nor too loose.
No space should remain between the cuff and the arm.

Lay the arm on a table with the palm upwards so that
the cuff is at the same height as the heart.

Connect the other end of the inflating tube to the
connector on the blood pressure monitor and start
measurement.

Measuring your blood pressure

After following the guidelines described in the previous section and placing the cuff around your
upper arm, you are now ready to measure your blood pressure. Follow these steps to record your
measurement.

Press the O/I button to turn on the device and start measurement.
The LCD screen is turned on. The cuff begins to inflate while the
increasing cuff pressure is displayed on the screen. After the
suitable inflation pressure is reached, the cuff stops inflating and
the pressure gradually falls. A long beep s ounds when the
measurement is completed. The systolic and diastolic blood
pressure values along with the pulse rate are displayed on the
screen. The measurement is displayed for approximately 3 minutes.

If problems occur when using the device, the following points should be checked,
and if necessary, the corresponding measures should be taken.

Malfunction

The display remains empty when
the instrument is switched.
Batteries have been in stalled.
The pressure does not rise although
the pump is running.
The instrument frequently fails to
measure blood pressure values, or
the values measured the are too
low (too high).

Every measurement produces a

different value although the
instrument functions normally and
the values displayed are normal
The Blood pressure values
measured differ from those
measured by the doctor.

Remedy

1. Check the polarity of the batteries (+/-)

2. If the display is erratic or unusual, remove ebatteries
and re-install new batteries.

1. Check the connection of the cuff tube and connect
properly if necessary.

1. Ensure the cuff fits correctly.

2. Make sure that the cuff is not fitted too
tightly.Ensure tight clothing such as a a rolled-up
sleeve isn’t exerting pressure on the arm above the
measuring position. Take off articles of clothing if
necessary.

Answers

Answers

How do I know if the device is still accurate after
long usage or after being dropped?

● Generally, the monitor gives accurate results if it is working. If for

example. the device has been dropped but you cannot detect any
malfunction when operating it, there is no need to worry about
the accuracy. The main component that mainly influences the
accuracy is stored in the computer program. This software either
works or doesn’t. Other parts which affect the accuracy such as
the deflation valve and the pressure sensor are very well
protected against modifications by accidents or ageing.

● In any case and in accordance with international standards we

recommed that you ask your authorised Microlife dealer to
perform an accuracy check every two years.

Why and when should send the device in for an

accuracy check?

● MICROLIFE’S blood pressure monitors are developed to remain

accurate for a long product life. To guarantee this accuarcy we
recommend-in accordance with international standards -that you
ask your authorised Microlife dealer to perform an accuracy check
every 2 years.

The systolic pressure measured by the MICROLIFE

blood pressure monitor is similar to what my doctor
measures but why is the diastolic pressure about 10
mmHg higher with the electronic monitor?

● The diastolic pressure is very difficult to detect with the

stethoscope and depend very much on the observer capabilities.
The correlation of the diastolic pressure is therefore typically
more difficult more difficult than the systolic.

How long should I wait between measurements?

● If you want to perform several measurements sequentially, you

should wait at least 5 minutes between two measurements. Loosen
the cuff during this waiting period to enable a normal blood flow.

How often and when shall I measure my blood

pressure with the MICROLIFE electronic blood
pressure monitor?

● The more you measure, the better! But as blood pressure is a very

much variable body parameter, be aware that the results are not
same. To compare your pressure level between each day, you
should preform a daily measurement under comparable living
situations. Measure, for example, an hour after you had dinner.
Make sure that you feel relaxed and not disturbed by your
environment.

What happens if do not place the wrist cuff at heart
level?

● It is very important that the cuff is positioned at heart level during

measurement. A position ten centimetres higher than heart level
means an underestimation by 8 mmHg while 10 centimetres below
heart level means 8 mmHg overestimation of the blood pressure.

Can I connect any cuff as long as it fits to the
connection port?

● MICROLIFE’S blood pressure monitors can only give reliable

results when the device is connected to a MICROLIFE cuff. If your
arm circumference is between 22 and 32 cm, you should use the
MICROLIFE “M-size” cuff. If it is between 32 and 42 cm, you
should use the MICROLIFE “L-size” cuff.

Can I wash the cuff?

● No, the cuffs of home monitors are generally not designed to be

washed. This might change the cuff dimensions and lead to a loss
in accuracy. But under normal application it is not required to wash
the cuff. Spot on the cuff can be removed carefully with a damp
cloth and soapsuds.

I already have an AC/AD adapter at home.
can I use it or do I need the MICROLIFE adapter?

● MICROLIFE’S blood pressure monitors require a very specific

power supply. This can only be guaranteed by the use of batteries
or the MICROLIFE AC adapter. The adapter is specifically designed
for our products.

Can I use rechargeable batteries?

● We do not recommend to use rechargeable batteries for our

devices.Electronic blood pressure monitors requires a specific
level of stable power supply. Even fully rechargeable batteries
have a lower capacity than non rechargeable batteries.
Rechargeable batteries may reach the lowest required power
limit for our products much faster than non rechargeable batteries.
Users of rechargeable batteries have to charge the batteries therefore
very often which does not motivate then to frequently perform home
measurements.

● Please note that the power supply does not has any influence on

the accuracy! If the power level is too low, the battery signal is
shown.As long as the device performs measurement, they are
reliable!

Is the MICROLIFE blood pressure monitor
waterproof?

● No! Also please prevent to store it above 50

What are normal results and when should I see a
doctor?

● The following table explains the pressure ranges and degree of hypertension according to

the World Health Organization:

● It is recommend that you record your blood pressure values frequently and discuss them with

your doctor. If your systolic values are frequently above 130 and/or the diastolic values above
85, you should consult your doctor. It is normal that blood pressure values are sometimes
higher and lower and there is no need to worry if the results are sometimes higher than the
above limits. But if your pressure is above the limits in most cases,you should consult
your doctor.

What is”White Coat Hypertension”?

● White Coat Hypertension (WCH) is the popular name for the effect

that the patients blood pressure might be detected on a higher
level when the measurement is performed by a doctor (in his
typical white coat) or a nurse. This effect is caused because one
often can be excited or nervous during such “official”
measurements and the pressure will be accordingly higher. The
problem is that the person may not have a pressure that is too
high under normal conditions but might be diagnosed as
hypertensive based on the doctors measurement. Home devices
are the best choice to prevent this “white coat effect”. Some long
term studies showed that people who have a higher pressure at
the doctor also have a high risk to develop hypertension. Thus,
these patients should check their pressure frequently.

Kindly fill-in your personal date on the front page.On the
following pages, please indicate exact date, time and weight
before any measurements. Start with your blood pressure and
pulse measurement and pulse measurement. Please fill-in your
systolic blood pressure (maximal Value), your diastolic blood
pressure ( minimal value) and your pulse rate. After the
measurement, kindly combine the systolic and diastolic values
as well as the pulse rates with a line (see example). With this
method, you may provide an exact overview of your blood
pressure / pulse to your doctor.
