ENGLISH Dear Customer,

Thank you for choosing one of our products. Our name stands

for high-quality, thoroughly tested products for the applications

in the areas of heat, weight, blood pressure, body temperature,

pulse, gentle therapy, massage and air.

Please read these instructions for use carefully and keep them

for later use, be sure to make them accessible to other users

and observe the information they contain.

1. Getting to know your instrument

Check that the packaging of the Beurer BM75 blood pressure

monitor has not been tampered with and make sure that all the

required contents are present. Before use, ensure that there

is no visible damage to the device or accessories and that all

packaging material has been removed. If you have any doubts,

do not use the device and contact your retailer or the specified

Customer Services address.

The upper arm blood pressure monitor is used for non-invasive

measurement and monitoring of adults’ arterial blood pressure.

You can use it to measure your blood pressure quickly and

easily, storing the results and displaying the progression of

readings together with the average.

A warning is issued for anyone suffering from cardiac arrhythmia.

The recorded values are classified and evaluated graphically.

This blood pressure monitor also has a haemodynamic stability

display, which is referred to as a resting indicator throughout

these instructions for use. This shows whether you, and con-

sequently your circulatory system, are sufficiently at rest when

the blood pressure measurement is being taken and is there-

fore a more precise indicator of your resting blood pressure.

Read more about this in chapter 6.

Keep these instructions carefully for further use and also let

other users have access to them.

The measurement can be performed on the left or right arm.

Fit the cuff round your bare left upper

arm. Blood circulation in the arm

should not be restricted by tight cloth-

ing or other objects.24

The cuff should be placed on the upper

arm so that the lower edge is 2 to 3 cm

above the bend of the elbow and

above the artery. The tube should be in

line with the centre of the palm.

Now tighten the free end of the cuff,

but make sure that it is not too tight

around the arm and close the

hook-and-loop fastener. The cuff

should be fastened so that two fingers

Now insert the cuff line into the

connection for the cuff connector.

If the measurement is performed on the right upper arm,

the line should be located on the inside of your elbow. En-

sure that your arm is not pressing on the line.

Blood pressure may vary between the right and left arm, which

may mean that the measured blood pressure values are differ-

ent. Always perform the measurement on the same arm.

If the values between the two arms are significantly different,

please consult your doctor to determine which arm should be

used for the measurement.

Important: The unit may only be operated with the original cuff.

The cuff is suitable for an arm circumference of 24 to 36 cm.

A larger cuff for upper-arm circumferences of 35 to 44 cm can

be obtained from specialist retailers or from the service ad-

dress using order number 163.387.

Rest for approx. 5 minutes before each measurement. Other-

wise there may be divergences.

You can perform the measurement either sitting or lying down.

Always make sure that the cuff is on a level with your heart.

To carry out a blood pressure measurement, make sure you

are sitting comfortably with your arms and back leaning on

something. Do not cross your legs. Place your feet flat on the

In order not to distort the result, it is important to keep still

during the measurement and not talk.25

Performing the blood pressure measurement

As described above, attach the cuff and adopt the pos-

ture in which you want to perform the measurement.

To start the blood pressure monitor, press

the Start/stop button . All display ele-

ments are briefly displayed.

The blood pressure monitor will begin the

measurement automatically after 3 seconds.

The cuff automatically inflates.

Measuring can be cancelled at any time by pressing

the Start/stop button .

The cuff’s air pressure is slowly released. If you already

recognise a tendency for high blood pressure, you should

reinflate the cuff and increase the cuff’s pressure again. As

soon as a pulse is found, the pulse symbol is displayed.

Systolic pressure, diastolic pressure and

pulse measurements are displayed. The

6. Evaluating results

This instrument can identify possible cardiac arrhythmia disor-

ders during measurement and if necessary indicates the meas-

urement with the flashing icon .

This may be an indicator for arrhythmia. Arrhythmia is a condi-

tion where the heart rhythm is abnormal as a result of defects

in the bioelectrical system controlling the heart beat. The symp

toms (omitted or premature heart beats, slow or excessively fast

heart rate) may be caused, among other things, by heart dis-

ease, age, physical predisposition, excessive use of stimulants,

stress or lack of sleep. Arrhythmia can only be ascertained

through examination by your doctor.

Repeat the measurement if the flashing icon is displayed

after the measurement. Please note that you should rest for

5 minutes between measurements and not talk or move dur-

ing the measurement. If the icon appears often, please

contact your doctor. Any self-diagnosis and treatment based

on the test results may be dangerous. It is vital to follow your

doctor‘s instructions.

Classification of measurements:

The measurements can be classified and evaluated in accor-

dance with the following table.

However, these standard values serve only as a general

guideline, as the individual blood pressure varies in different

people and different age groups etc.

It is important to consult your doctor regularly for advice. Your

doctor will tell you your individual values for normal blood

pressure as well as the value above which your blood pressure

is classified as dangerous.

The classification on the display and the scale on the unit show

which category the recorded blood pressure values fall into. If

the values of systole and diastole fall into two different cate-

gories (e.g. systole in the ‚High normal‘ category and diastole

in the ‚Normal‘ category), the graphical classification on the de-

vice always shows the higher category; for the example given

this would be ‚High normal‘.

Resting indicator measurement (using HSD diagnostics)

The most frequent error made when measuring blood pressure

is taking the measurement when not at rest (haemodynamic

stability), which means that both the systolic and the diastolic

blood pressures are incorrect in this case.

While measuring the blood pressure, the device automatically

determines whether you are at rest or not.

If there is no indication that the circulatory system is not suf-

ficiently at rest, the symbol

(haemodynamic stability) lights

up green and the measurement can be recorded as a reliable

resting blood pressure value.27

GREEN: Haemodynamic stability

Measurement of the systolic and diastolic pressure is in-

creased when the circulatory system is sufficiently at rest and

is a very reliable indicator of resting blood pressure.

However, if there is an indication that the circulatory system is

not sufficiently at rest (haemodynamic instability), the symbol

In this case, the measurement should be repeated after a pe-

riod of physical and mental rest. The blood pressure measure-

ment must be taken when the patient is physically and mentally

rested, as it will be the basis for diagnosing the blood pressure

level and regulating the patient’s medical treatment.

If the symbol does not light up green or red, then it could

not be determined whether the circulatory system was suf-

ficiently at rest or not. In this case, the measurement should be

repeated after a period of physical and mental rest.

RED: Lack of haemodynamic stability

It is very probable that the systolic and diastolic blood pressures

have not been measured whilst the patient is at rest and the rest

ing blood pressure measurement has therefore been distorted.

Repeat the measurement after a rest and relaxation period of

at least five minutes. Go to a sufficiently quiet and comfortable

spot and remain there calmly; close your eyes, breathe deeply

and evenly and try to relax.

If the next measurement also shows insufficient stability, you

can repeat the measurement after another resting period. If the

measurements continue to show some instability, identify these

blood pressure measurements as having been taken when the

circulatory system had not been sufficiently rested.

In this case, nervousness or inner anxiety may be the cause and

this cannot be cured by brief periods of rest. Existing cardiac ar-

rhythmias may also prevent a stable blood pressure measurement.

g blood pressure can have various causes, such

as physical or mental strain or distraction, speaking or experi-

encing cardiac arrhythmias during the measurement.

In an overwhelming number of cases, the HSD diagnosis will

give a very good guide as to whether the circulatory system

is rested when taking the measurement. Certain patients suf-

fering from cardiac arrhythmia or chronic mental conditions

can remain haemodynamically unstable in the long-term,

something which persists even after repeated periods of rest.

The accuracy of the resting blood pressure results is reduced

in these users. Like any medical measurement method, the

precision of the HSD diagnosis is limited and can lead to incor-

rect results in some cases. The blood pressure measurements

taken when the circulatory system was at rest represent par-

ticularly reliable results.
