The cuff is first placed as shown in the illustration on the cuff on the upper arm
and then connected to the unit. When the Start/Stop button is pressed, the system
starts to build up pressure automatically. Within a very short space of time the
unit records the small oscillations within the cuff which occur owing to expansion
and contraction of the arteries in the arm (heartbeat).The automatic build-up of
pressure usually stops approx. 40 mmHg above the systolic value (fuzzy logic).
Then the actual measurement process starts while the cuff is being deflated. The
amplitude of each pressure wave is measured in millimetres of mercury (mmHg),
converted and displayed in the LCD as a digital value. Systole, diastole and pulse
are determined, after which the cuff is completely deflated.
Table of contents Table of contents
Thank you for choosing the visomat®comfort eco upper arm blood pressure
monitor (also referred to in the following as the unit).
visomat®comfort eco uses the oscillometric method for measuring blood pressure
and pulse rate on the upper arm.
Mode of operation:
As well as indicating systole, diastole and pulse, the unit offers additional displays
for determining irregular pulses and pulse pressure. Irregular pulses may be an in-
dication of an irregular heartbeat but also of restlessness during the measurement.
This unit is recommended to patients with unstable blood pressure for measuring
their blood pressure at home and for therapy support.

Safety instructions
Important patient instructions1.
The unit is designed for non-invasive measurement of the systolic and dias-
tolic blood pressure on the upper arm, as well as measurement of the pulse
rate of adults, i.e. 15 years of age and older. Blood pressure measurements on
children require specialist knowledge! Please consult your doctor if you wish
to measure the blood pressure of a child. Do not under any circumstances use
the unit on a baby/infant.
•
The standard cuff supplied is designed for an upper arm circumference of
22-32 cm. A larger cuff (accessory Page EN-48) is optionally available for arm
circumferences of 32-42 cm.
•
The measurement results of automatically measuring blood pressure monitors
may be falsified by pregnancy, irregular heartbeats, or arteriosclerosis. Measu-
re your own blood pressure in cooperation with your doctor.
•
Measuring your own blood pressure does not constitute treatment. Do not
modify of you own accord the dosage of drugs/medication prescribed by your
doctor.
•
Do not under any circumstances place the cuff on or over any critical point,
e.g. wound, aneurysm, etc. Risk of injuries! The supply via an intravascular
access (infusion) could possibly be interrupted.
•
Please refer to the chapter „Important instructions for use“ (Page EN-36)
before conducting any measurements yourself.
•
The unit must only be operated with original spare parts. The warranty will be
invalidated if the unit is damaged by non-approved accessories!
•
Using this unit near mobile phones, microwave ovens or other devices with
strong electromagnetic fields may lead to malfunctions. See also EMC descrip-
tion from Page EN-51.
•
The display of the pulse frequency is not suitable for checking the frequency
of cardiac pacemakers. Cardiac pacemakers and blood pressure monitors do
not influence each other regarding their mode of operation.
•
Never open or modify the unit or the cuff - this is a medical device. (Excepti-
on: replacing batteries). If the unit has been opened, it must be subjected to a
metrological inspection by an authorised institution.
•

degree of stress/exertion, this can even require up to one hour.
•
Refrain from drinking alcoholic or caffeinated beverages and smoking at least
one hour before measuring.
•
Expose the upper arm, the clothes must not impair the blood flow in or from the
arm as this influences the blood pressure at the measurement point.
•
Important instructions for use3.
Resting during the measurement is absolutely essential! Talking or moving
as well as strong irregular heartbeats will affect the measurement result, the
values becoming too high.
•
Insert the supplied batteries into the unit, if these have not been inserted already.
Initial operation of the unit4.
Remove the cover of the battery compartment on the underside of the unit.
Opening the battery compartment•
Remove the old batteries from the unit and insert the new ones. Please
observe proper polarity (marking in battery compartment).

Please note:•
if the flat battery symbol appears in the display
during or after the segment check.
–
if the display remains blank in spite of the Start/
Stop button being pressed.
–
For this purpose, sit at a table (if possible the height of a dining table, not
a coffee table!).
–
Body posture must be relaxed:•
Rest your back against the backrest of the chair.–
Lay down your lower arm completely. Make sure the palm of your hand is facing–
Place your feet on the floor and do not cross your legs.–
There should be no irregular heartbeats during the measurement! Irregular
movements, vibrations, speaking, and breathing heavily will also affect the
measurement. Listen out for regular pulse beep signals during measurement;
if necessary, repeat the measurement in improved conditions.
•
Unusual measurement results are possible with all automatically measur-
ing blood pressure measurement systems from time to time. Check yourself:
did you comply with the instructions for use above? If necessary, repeat the
measurement after allowing the blood circulation in the arm to recuperate
briefly; rest for about 3-5 minutes for this purpose. Tip: Remain seated, your
monitor will switch off automatically about 3 minutes after a measurement.
Afterwards, we recommend that you repeat the measurement.
•
If the unit is to be operated from the mains power supply, the cable plug of the
mains adapter (accessory, Page EN-48) must be inserted into the connection socket
on the right side of the unit. The batteries are switched off automatically.

Expose the upper arm.•
Push the cuff onto the arm until the lower edge
of the cuff is 2-3 cm above the crook of the arm.
•
When using the unit on the left arm the air hose
runs to the unit through the middle of the crook
of the arm so that the 4 cm long artery marking
is located centrally above the pulse position.
•
When using the unit on the right arm the cuff
must be rotated to the left until the artery mark-
ing is on the pulse position. The air hose then
runs along the inner side of the upper arm.
•
Now pull the free cuff end tight and flip it back
tightly above the Velcro fastener.
•
Check if the arrow on the cuff is within the mark-
ing at the edge of the cuff.
•
Insert the air connector of the cuff into the air
socket on the unit.
•
Relax and lay your extended arm with the cuff on
the dining table and do not move it during the
measurement; do not talk. Make sure the palm of
your hand is facing upwards.

Switch on the unit by pressing the Start/Stop
button. The following display is visible.
•
The automatically controlled inflation process
begins once the unit has completed its calibration
against the ambient air pressure.
•
Then the actual measurement process starts
while the cuff is being deflated. The „♥“ symbol
flashes in the display, and a beep sounds to
denote the pulse frequency.
•
A long beep denotes the end of measurement.
The cuff is automatically deflated.
•
The cuff should be tightened to such an extent
that 2 fingers can still be inserted between arm
and cuff. Tip:
•
Angle the arm slightly.–
The upper arm muscle is tensioned slightly.–
This increases the circumference of the arm
slightly.
–
The determined values of systole, diastole and
pulse and the pulse pressure (PP) are shown
alternately in the display.

WHO traffic light function8.
The unit categorises the blood pressure readings according to the guidelines of
the World Health Organisation (WHO). You can use the coloured fields to read the
categorisation of each reading:
WHO 2003 * It is sufficient
for one of the
values to be
raised.
Pulse pressure9.
The pulse pressure – not to be confused with the pulse beat – provides an
indication of the stretchability of the blood vessels. High pulse pressure can have a
negative effect on the cardiovascular system. Studies show that the cardiovascular
risk increases if the pulse pressure value is greater than 65 mmHg.
Lower dot (Green) signifies normal value–
Middle dot (Yellow) signifies borderline value*–
Upper dot (Red) signifies high pressure*–
The categorisation according to WHO is stored with the readings and can be called
up again together with the readings from the memory.
The heart works in two phases, the contraction phase (systole) and the relaxation
phase (diastole). The pressure difference between systole and diastole is called the
pulse pressure or pulse amplitude. The higher the pulse pressure, the harder the
vessels.
** millimetres
of mercury
High pulse pressure above 65 mmHg
Increased pulse pres-
sure 55 to 65 mmHg
Normal pulse pressure below 55 mmHg
If your pulse pressure is permanently above 55 mmHg, consult your doctor.
If the symbol appears more frequently, this may
be caused by an irregular heartbeat and must be
discussed with your doctor! Measurement results
accompanied by flashing pulse displays should the-
refore be viewed as critical and repeated under more
favourable conditions.
Irregular pulse waves10.
If the symbol for irregular pulse waves flashes after a
measurement, the unit has recorded irregular pulses
during the measurement. This can be set off by an
irregular heartbeat (arrhythmia), disturbances caused
by movement, talking or even breathing in deeply. The
symbol is stored with the respective measurement.

What you should know about blood pressure
Why you should measure blood pressure regularly3.
Even the time of day has an influence on your blood pressure. During the day the
values are generally higher than during the periods of rest at night. One-off and
irregular measurements therefore say little about your actual blood pressure. A re-
liable assessment is possible only when measurements are taken regularly. Discuss
the measurement values with your doctor.
Systolic and diastolic blood pressure values1.
The cardiovascular system has the important function of supplying all organs and
tissues in the body with sufficient amounts of blood and of transporting metabolites.
For this, the heart contracts and expands at a regular rate of about 60 to 80 times
per minute.The pressure of the flowing blood on the artery walls caused by the heart
contracting is termed systolic.The pressure in the ensuing relaxation phase, when the
heart refills with blood, is termed diastolic. During daily measurement you determine
both values.
Reasons for measuring different values2.
Our blood pressure responds to internal and external influences like a sensitive
measuring instrument. It can be affected by even slight changes. This explains
why often values measured with the doctor or pharmacist are higher than those
measured at home in the environment you are used to. Changes in the weather,
climate changes, or physical or psychological stress can have effects as well.
When more than 30 measured values have been stored, the oldest value (No. 30)
is deleted to allow the latest value (No. 1) to be recorded. Press the Memory but-
ton to call up data. The average value of the stored results is displayed with „A“,
the values for systole, diastole and pulse and the pulse pressure (PP) are shown
alternately in the display.
Press the button repeatedly to call up further measured values. If no value is
stored, nothing will be displayed (just dashes). The stored data remain visible in the
display for around 30 seconds. The unit then switches itself off.
To delete individual measured values, press the Memory button repeatedly to call
up the desired measured value. Then press the Memory button again and hold
down for 8-10 seconds until the measured value first flashes and then disappears
completely.
To delete the entire memory, call up the average value, press the Memory button
again and hold down until the average value first flashes and then disappears
completely.
If no measured values are stored or after the memory has
been deleted, the following display appears when the
memory is called up:
Measured results are automatically stored in the memory. The memory can store up
to 30 results and the average value.
