1. Introduction

1.1. Features of the BP 3BU1-5

The blood-pressure monitor BP 3BU1-5 (with integrated time/date
display) is a fully automatic, digital blood-pressure measuring device
for use on the wrist, which enables very fast and reliable measure­ment of the systolic and diastolic blood-pressure as well as the pulse
frequency by way of the oscillometric method of measuring.The de­vice offers a very high and clinical tested measurement accuracy and
has been designed to provide a maximum of user-friendliness.
Before using, please read through this instruction manual carefully
and then keep it in a safe place. For further questions on the subject
of blood-pressure and its measurement, please contact your doctor.

Attention!

1.2. Important information about self-measurement

• Do not forget: self-measurement means control, not diagnosis
or treatment. Unusual values must always be discussed with
your doctor. Under no circumstances should you alter the
dosages of any drugs prescribed by your doctor.

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

• In cases of cardiac irregularity (Arrhythmia), measurements
made with this instrument should only be evaluated after con­sultation with the doctor.

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 6

2. Important information on the subject of blood-pressure
and its measurement

2.1. How does high/low blood-pressure arise?

The level of blood-pressure is determined in a part of the brain, the
so-called circulatory centre, and adapted to the respective situation
by way of feedback via the nervous system.
To adjust the blood-pressure, the strength and frequency of the heart
(Pulse), as well as the width of circulatory blood vessels is altered.
The latter is effected by way of fine muscles in the blood-vessel
walls.
The level of arterial blood-pressure changes periodically during the
heart activity: During the «blood ejection» (Systole) the value is maxi­mal (systolic blood-pressure value), at the end of the heart’s «rest pe­riod» (Diastole) minimal (diastolic blood-pressure value).
The blood-pressure values must lie within certain normal ranges in
order to prevent particular diseases.

2.2. Which values are normal?

Blood pressure is too high if at rest, the diastolic pressure is above
90mmHg and/or the systolic blood-pressure is over 160mmHg. In this
case, please consult your doctor immediately. Long-term values at
this level endanger your health due to the associated advancing
damage to the blood vessels in your body.
Should the systolic blood-pressure values lie between 140mmHg and

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 7

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.
If you are undergoing medical treatment to control your blood pres­sure, please keep a record of the level of your blood pressure by car­rying out regular self-measurements at specific times of the day.
Show these values to your doctor. Never use the results of your

measurements to alter independently the drug doses pre­scribed by your doctor.

Table for classifying blood-pressure values (units mmHG) according
to World Health Organization:

Range Systolic Diastolic Measures

Blood-pressure Blood-pressure

Hypotension lower than 100 lower than 60 Check with

your doctor

Normal range between 100 between 60 Self-check

and 140 and 90
Mild between 140 between 90 Consult your
hypertension and 160 and 100 doctor
Moderately between 160 between 100 Consult your
serious and 180 and 110 doctor
hypertension
Serious higher than 180 higher than 110 Consult your

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 8

hypertension». Please consult your doctor if you suspect that
this might be the case.

• Correctly measured diastolic blood-pressure values above

120mmHg require immediate medical treatment.

2.3. What can be done, if regular increased/low values are

obtained?

a) Please consult your doctor.
b) Increased blood-pressure values (various forms of hypertension)

are associated long- and medium term with considerable risks
to health. This concerns 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 continuously increased blood-pres­sure values, the heart will become structurally damaged.

c) There are many different causes of the appearance of high

blood pressure. We differentiate between the 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.

d) There are measures which you can take, not only for reducing a

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 9

5. Carrying out a measurement

5.1. Before the measurement:

•Avoid eating, smoking as well as all forms of exertion directly

before the measurement. All these factors influence the mea­surement result. Try and find time to relax by sitting in an arm­chair in a quite atmosphere for about ten minutes before the
measurement.

• Measure always on the same wrist (normally left).

• Attempt to carry out the measurements regularly at the same

time of day, since the blood-pressure changes during the course
of the day.

5.2. Common sources of error:

Note:
Comparable blood-pressure measurements always re­quire the same conditions! These are normally always
quiet conditions.

• 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.

• If the wrist artery lies considerably lower (higher) than the

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 18

peated after a 5 minute pause or after the arm has been held up
in order to allow the accumulated blood to flow away (after at
least 3 minutes).

5.3. Fitting the cuff

a) Remove all eventual objects

and jewellery (e.g.
wristwatch) from the wrist
in question. Draw the
cuff over the wrist.

b) The distance between the

cuff and the hand should
be approx. 10 mm.

c) Secure the cuff with the

Velcro fastener, so that it
lies comfortably and not too
tight, whereby no space
should remain between the
cuff and the wrist.

d) Lay the arm on a table, with

the palm upwards.Support the

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 19

5.4. Measuring procedure

After the cuff has been appropriately positioned, the measurement
can begin:

a) Press the 0/I-button, the

pump begins to inflate the
cuff. In the display, the in­creasing cuff-pressure is
continually displayed.

b) After reaching the inflation

pressure, the pump stops
and the pressure slowly
falls away. The cuff-pressure
(large characters) is dis­played during the measure­ment. When the device has
detected the pulse, the heart
symbol in the display begins
to blink and a beep tone is
audible for every pulse beat.

c) When the measurement has

been concluded, a long beep
tone sounds. The measured

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 20

The measurement results are displayed, until you switch the device
off. If no button is pressed for 5 minutes, the device switches auto­matically off, to save the batteries.

d) When the unit is set to Average Mode

setting generally 3 separate measure­ments will take place in succession and
calculates your detected blood pressure
value. There will be 35 seconds resting
time in-between each measurement. A
count down indicates the remaining time
and a beep will sound 5 seconds before the
2nd and 3rd readings will begin.
In case that the single data of each cycle differ too much from
each other, a fourth measurement is performed before the re­sult will be displayed. In rare cases the blood pressure is such
unstable that even after four measurements the data vary too
much. In this case „ERR 6“ is shown and no result can be given.
If one of measurement causes an error message it is repeated.

5.5. Discontinuing a measurement

If it is necessary to interrupt a blood
pressure measurement for any reason
(e.g. the patient feels unwell), the 0/I

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 21

5.6. Memory – storage and recall of the measurements

The blood-pressure monitor automatically
stores each of the last 30 measurement val­ues. By pressing the MEMORY button, the
last measurement (MR1) as well as the fur­ther last 29 measurements (MR2, MR3, ...,
MR30) can be displayed one after the other.

(MR1: Values of the (MR2-MR30: Values of the
last measurement) measurement before MR1)

☞ Further information

Measurements should not occur soon after each other, since other­wise, the results will be falsified. Wait therefore for several minutes
in a relaxed position, sitting or lying, before you repeat a measure­ment.

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 22

In order to delete all stored readings,
depress the MEMORY button for at
least 7 seconds, the display will show
the symbol " CL” and 3 short beep
sounds will be heard to indicate dele­tion of stored readings.

Note:

If your last stored measure­ment was taken in the Average
Mode, you will see the „MAM“
symbol in approximately
3 seconds during the deletion
procedure. (The display will
show these symbols during
deletion of all stored measure­ments if the last measurement
is taken from the Average Mode)

6. Printer Funtions

This unit can be used in connection with the Microlife diagnostic
printer. The unit can print out measurements stored in the memory by
pressing the PRINTER button. There are 2 kinds of formats available.

☞ Further Information

The level of blood-pressure is subject to fluctuations even with
healthy people. Important thereby is, that comparable measure-

ments always require the same conditions (Quiet conditions)!

If, in spite of observing all these factors, the fluctuations are larger
than 15mmHg, and/or you hear irregular pulse tones on several occa­sions, please consult your doctor.

For licensing, the device has been subjected to strict clinical tests, by
which the computer programme used to measure the blood-pressure
values was tested by experienced specialist doctors in Germany. The
same computer programme is used in every individual device, and
has thus also been clinically tested.
The manufacture of the devices takes place according to the terms of
the European standard for blood-pressure measuring devices (see
technical data) under the supervision of the Technical Monitoring
Association Essen (RWTüV-Essen).

You must consult your specialist dealer or chemist if there are tech­nical problems with the blood-pressure instrument. Never attempt to
repair the instrument yourself!
Any unauthorised opening of the instrument invalidates all guaran­tee claims!

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 27

8. Care and maintenance, recalivration

a) Do not expose the device to either

extreme temperatures,
humidity, dust or direct sunlight.

b) The cuff contains a sensitive

air-tight bubble. Handle this
carefully and avoid all types
of straining through twisting
or buckling.

c) Clean the device with a soft,

dry cloth. Do not use petrol,
thinners or similar solvent.
Spots on the cuff can be re­moved carefully with a damp
cloth and soapsuds. The cuff
must not be washed!

d) Do not drop the instrument or

treat it roughly in any way.

IB BP 3BU1-5 VarB 0702.qxd 13.08.2002 8:41 Uhr Seite 28

Periodical recalibration

Sensitive measuring devices must from time to time be checked for
accuracy. We therefore recommend a periodical inspection of the
static pressure display every 2 years.
Your specialist dealer would be pleased to provide more extensive
information about this.
