1. Introduction
1.1. Features of the WA-22H
The blood-pressure monitor WA-22H is a semi-automatic, digital blood-pressure measuring device for
use on the upper arm, 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.
Thanks to the large LCD display of WA-22H, both operational status and cuff pressure are visible for
the entire duration of the measurement.
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
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 elec-
trical 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.

2.1. 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 circ-
ulatory blood vessels is altered. The latter is effected by way of fine muscles in the blood-vessel walls.
wa-22h.indd 2 13.04.2006 16:10:38

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 dis-
eases.
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 95 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 105 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 approp-
riately.
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 conditi-
ons 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 120 mmHg 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 de-
ficient 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 medically established high blood
pressure, but also for prevention. These measures are part of your general way of life:
A) Eating habits
Strive for a normal weight corresponding to your age. Reduce overweight!
Avoid excessive consumption of common salt.
Avoid fatty foods.
B) Previous illnesses
Follow consistently any medical instructions for treating previous illness such as:
Diabetes (Diabetes mellitus)
Fat metabolism disorder
Gout
C) Habits
Give up smoking completely
Drink only moderate amounts of alcohol
Restrict your caffeine consumption (Coffee)

D) Physical constitution
After a preliminary medical examination, do regular sport.
Choose sports which require stamina and avoid those which require strength.
Avoid reaching the limit of your performance.
With previous illnesses and/or an age of over 40 years, please consult your doctor before beginning
your sporting activities. He will advise you regarding the type and extent of types of sport that are
possible for you.

batteries are empty and must be replaced by
new ones.
Attention!
After the battery warning appears, the device is
blocked until the batteries have been replaced.
Please use «AA» Long-Life or Alkaline 1.5 V Ba-
tteries. The use of 1.2 V Accumulators is not
recommended.
If the blood-pressure monitor is left unused for
long periods, please remove the batteries from
the device.

5. Carrying out a measurement
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
quiet atmosphere for about ten minutes before the measurement.
Remove any garment that fits closely to your upper arm.
Measure always on the same arm (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 arm artery lies considerably lower (higher) than the heart, an erroneously higher (lower)
blood-pressure will be measured! (Each 15 cm difference in height results in a measurement error
of 10 mmHg!)
Cuffs that are too narrow or too short result in false measurement values. Selecting the correct
cuff is of extraordinary importance. The cuff size is dependent upon the circumference of the arm
(measured in the centre). The permissible range is printed on the cuff. If this is not suitable for
your use, please contact your dealer. Note: only use clinically approved Original-Cuffs!
A loose cuff or a sideways protruding air-pocket causes false measurement values.
With repeated measurements, blood accumulates in the respective arm, which can lead to false
results. Correctly executed blood-pressure measurements should therefore first be repeated after
a 1 minute pause.
