1. Introduction
1.1. Features of the Wrist Digital BP Monitor
The blood-pressure monitor Wrist Digital BP Monitor (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. The device is intended for self-use in
home .
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
•Substitution of a different component might result in measurement error.
•Do not use with neonatal patients.
•Do not intend to use with pregnant or pre-eclamptic patients
•Too frequent measurements can cause injury to the patient due to blood flow interference.
•The application of the cuff over a wound can cause further injury.
•The application of the cuff and its pressurization on any limb where intravascular access or therapy, or an
arteriovenous (A-V) shunt, is present because of temporary interference to blood flow and could result in
injury to the patient.
•Do not let the cuff and its pressurization on the arm on the side of a mastectomy
•Pressurization of the cuff can temporarily cause loss of function of simultaneously used monitoring ME
equipment on the same limb.
•The need to check that operation of the automated sphygmomanometer does not result in prolonged
impairment of patient blood circulation.
•Not intended to be used together with HF surgical equipment.
• 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.
Electromagnetic interference
The device contains sensitive electronic components (Microcomputer). Therefore, avoid strong electrical or
electromagnetic fields in the direct vicinity of the device (e.g. mobile telephones, microwave cookers). These
can lead to temporary impairment of the measuring accuracy.

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 periodicallyduring 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 90 mmHg and/or the systolic
blood-pressure is over 160 mmHg. 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 140 mmHg and 160 mmHg and/or the diastolic blood-pressure
values lie between 90 mmHg and 100 mmHg, likewise, please consult your doctor. Furthermore, regular self-checks
will be necessary.
With blood-pressure values that are too low, i.e. systolic values under 100 mmHg and/or diastolic values
under 60 mmHg, likewise, please consult 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. 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.

Further information
• If your values are mostly standard 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».
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.

to minutes mode, or altering the value by +1).
However, if you keep the respective button depressed, you can switch more quickly to find the desired value
respectively.
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

10
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:
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. Use a cushion for
support if necessary.
•The performance of the automated sphygmomanometer can be affected by extremes of temperature, humidity
and altitude.
• If the wrist artery lies considerably lower (higher) than the heart, an erroneously higher (lower)
blood-pressure will be measured! (Each 15cm difference in height results in a measurement error of
10mmHg!)
• A loose cuff causes false measurement values.
• With repeated measurements, blood accumulates in the respective wrist which can lead to false results.
Correctly executed blood-pressure measurements should therefore first be repeated after a 5 minute pause or
after the armhas 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 arm a little with a rest (cushion), so that the
cuff rests at about the same height as the heart. Take care, that the
cuff lies free. Remain so for 2 minutes sitting quietly,
before beginning with the measurement.
e) Let legs uncrossed, feet flat on the floor, back and arm supported.
