METHOD OF MEASUREMENT
This product employs the oscillometric method for measurement of blood
pressure and heart rate. The entire system, including the cuff, is a single
wrist-mounted unit. The cuff is wrapped around the wrist and automatically
pressurized. Circuits within the cuff sense the small oscillations in pressure
against the cuff produced by the expansion and contraction of the arteries in
the wrist in response to each heart beat. The amplitude of each pressure
waves is measured, converted to millimeters of mercury, and displayed on the
LCD as a digital value. Responding to heart beats, the electromagnetic
INDICATIONS FOR USE
The WS-820 system is intended for the non invasive measurement of systolic
and diastolic blood pressure and determination of heart rate in adult, i.e., age
15 and above. The product is recommended for use by people with labile
(unstable) blood pressure or known hypertension in a home care environment
as an adjunct to medical management. The cuff will accommodate a wrist
circumference range of approximately 125 to 215 millimeters. Pressure is
measured over a range of 0 to 300 mmHg and heart rate over a range of 40 to
160 beats/minute.

BASIC PRODUCT INFORMATION
-10-

Blood pressure is a measurement of the force exerted by the heart in pumping
the blood through the arteries and the resistance by the veins to this flow.
Blood pressure varies all the time, influenced by mental and physical
factors and is never constant.
In general, blood pressure is highest during the working hours and gradually
decreases during the afternoon and evening hours. It is low during sleep and
increases at a relatively fast rate after arising from bed.
Causes for Changes in Blood Pressure
• Body movement • Conversation • Mental Tension • Nervousness
• Emotions • Eating • Drinking Alcohol • Smoking
• Recent Urination or Bowel Movement • Temperature
• Changes in the surroundings such as movement or noise, etc.
Before taking blood pressure, rest for approximately five minutes and
take your blood pressure while relaxed in a quiet environment.
Measure blood pressure using the correct posture and do not move
nor speak during measurement.
Avoid exercise, eating, drinking alcohol, smoking and other activities
that affect your blood pressure right before a measurement.
Take your blood pressure at the same time every day.
The ambient temperature should be approximately 20˚C when you
take your blood pressure.
Blood pressure measured at home tends to be lower than when
measured in a hospital, clinic or doctor's office.
This is because you are tense at the hospital and relaxed at home. It is
important to know your stable normal blood pressure at home.
Blood pressure at the wrist may be different from that at the upper arm.
As the thickness of the blood vessels differs depending on measuring position,
blood pressure value measured at the wrist may be slightly different from that
measured at the upper arm. In most cases, the difference for a healthy person
will be within about ±10mmHg for the systolic and the diastolic blood pressure.
Caution is required for the following persons: persons with hypertension,
diabetes, liver trouble, hardened arteries, peripheral hindrance of circulation,
etc., as there may be a difference between the values measured at the wrist
and those measured at the upper arm.
Let a qualified physician interpret your blood pressure readings.
Depending on your age, weight and general condition, blood pressure can be
slightly different. Consult with your doctor on determining what blood pressure
is normal for you.

To stop measurement
Press START button and the unit stops inflation, discharges air
rapidly, and then turns off.
1. Sit on a chair.
2. Lightly open your left hand, with your palm up, and put your elbow on
a table or stand.
3. Adjust the cuff to the same height as your heart with a comfortable
support such as a folded towel etc.
Hold your elbow if you do not have an appropriate table to put your
elbow on.
Breathe deeply and relax!
Make sure the cuff is wrapped correctly and it is at the same height
as your heart.
Do not move, chat or strain your arm or hand during measurement.
Measurement can be made lying on your back. Make sure that the cuff is
at the height of your heart. Reading may vary slightly, depending on
posture, whether sitting or lying.
If the cuff is lower (higher) than the heart, the measured reading
tends to become larger (smaller).
CORRECT MEASURING POSTURE
WRAPPING THE CUFF AROUND YOUR WRIST
the cuff and your wrist. The cuff should fit snugly. Press the surface of
the cuff to make sure the hook and loop attaches securely.
Position the cuff directly the skin. Take care that your clothes are not caught
by the cuff.

MEASURING METHOD Fig.5 page 6
1. Press START button.
The cuff is automatically inflated to the applied pressure.
Pressure (displayed value) starts to decrease and pulse is indicated by
heart mark.
When the measurement is complete, air is automatically released from the
cuff.
Maximum and minimum blood pressures and pulse rate are displayed.
-13-

Automatic Repressurization
If the pressure applied is judged insufficient in the early phase of
measurement or if movement of the hand or wrist occurs during
measurement, the unit will inflate again to a level about 40 mmHg higher.
Automatic Repressurization is repeated until a measurement is made.
However, this does not indicate a problem.
To manually control pressurization, hold down START button immediately
after the start of inflation and release it when the pressure reaches the
level 50 mmHg higher than the expected maximum systolic pressure. If the
pressure value has exceeded 190 mmHg, the inflation will stop when the
key is released. Pressure can be increased to approximately 300 mmHg.

rhythm. Irregular pulse rhythm can be a
result of body movement during
measurement or can be because of
arrhythmias. Although constant
appearance of the indication under quiet
measurements may suggest arrhythmias,
do not make any judgment on your own
before consulting with your doctor.

MEASUREMENT ERROR
Measurement could not be made because of moving or talking
during measurement. Remain still and quiet during
measurement.
INFLATION ERROR
The cuff is not properly applied. Properly apply the cuff.
If Err-2 appears after re-trying to apply the cuff properly, assume
the cuff is damaged. Contact your dealer.
DEFLATION ERROR
Movement or talking was detected during measurement. Turn off
the power and make another measurement while being quiet
and still.

Bei diesem Produkt wird die oszillometrische Methode zur Messung von Blutdruck
und Herzfrequenz angewendet. Das gesamte System, einschließlich der
Manschette, ist ein an einem einzigen Handgelenk angebrachtes Gerät. Die
Manschette wird um das Handgelenk gewickelt und automatisch unter Druck
gesetzt. Stromkreise innerhalb der Manschette spüren die geringen Schwingungen
des Drucks gegen die Manschette, die durch Ausdehnung und Zusammenziehen
der Arterien im Handgelenk als Reaktion auf jeden Herzschlag entstehen. Die
Amplitude jeder Druckwelle wird gemessen, in Millimeter/ Quecksilber umgewandelt
und auf dem LCD als digitaler Wert angegeben. Als Reaktion auf Herzschläge
hält das elektromagnetische Auslass-Steuerungsventil die gleichbleibende
GEBRAUCHSANWEISUNG
Das System WS-820 dient der nicht-invasiven Messung des systolischen und
diastolischen Blutdrucks sowie der Bestimmung der Herzfrequenz bei erwachsenen

Bei der Blutdruckmessung wird die Kraft, mit der das Herz das Blut durch die
Arterien pumpt und der dem Blutfluß entgegenwirkende Widerstand der Venen
gemessen.
Der Blutdruck wechselt aufgrund mentaler und körperlicher Faktoren
ständig und ist nie konstant.
Im allgemeinen ist der Blutdruck tagsüber während der normalen Arbeitszeit
am höchsten und fällt im Verlauf des Nachmittags und Abends. Im Schlaf ist
der Blutdruck niedrig und steigt nach dem Erheben vom Bett relativ schnell an.
Gründe für Veränderungen des Blutdrucks
• Körperbewegung • Unterhaltung • Mentale Spannung • Gefühle
• Mahlzeiten • Alkoholgenuss • Rauchen
• Kürzliche Urination oder Stuhlgang • Temperatur
• Änderungen in der Umgebung wie Bewegungen oder Geräusche usw.
Vorher etwa fünf Minuten ruhen und dann in ruhiger und entspannter
Umgebung den Blutdruck messen.
Den Blutdruck bei korrekter Körperhaltung messen und während der
Messung nicht sprechen und nicht bewegen.
Vermeiden Sie vor der Messung des Blutdrucks körperliche
Anstrengung, Essen, Alkoholkonsum, Rauchen und sonstige
Aktivitäten, die den Blutdruckwert beeinflussen.
Messen Sie täglich zur gleichen Uhrzeit.
Die Außentemperatur sollte während der Blutdruckmessung etwa
20°C betragen.
Der zu Hause gemessene Blutdruck ist tendenziell niedriger als der im
Krankenhaus oder in der Arztpraxis gemessene Blutdruck.
Das liegt daran, dass Sie im Krankenhaus angespannt, zu Hause aber
entspannt sind. Es ist wichtig, dass Sie Ihren stabilen normalen Blutdruck zu
Hause kennen. Blutdruckwerte geringfügig von den am Oberarm gemessenen
unterscheiden. In den meisten Fällen liegt die Differenz bei einem gesunden
Menschen in einem Bereich von ca. +10 mmHg für den systolischen und den
diastolischen Blutdruck. Bei folgenden Personen ist Vorsicht geboten:
Personen mit Hypertonie, Diabetes, Leberproblemen, verhärteten Arterien,
peripheren Durchblutungsstörungen usw.; hier kann ein Unterschied zwischen
den am Handgelenk und den am Oberarm gemessenen Werten vorliegen.
Der Blutdruck am Handgelenk kann sich von dem am Oberarm
unterscheiden.
Da die Messposition und die Dicke der Blutgefäße unterschiedlich sind,
können sich die am Handgelenk gemessenen
Lassen Sie Ihre Blutdruckwerte von einem Arzt auswerten.
Der Blutdruck kann sich in Abhängigkeit von Ihrem Alter, Gewicht und
Allgemeinzustand geringfügig unterscheiden. Ziehen Sie niemals irgendwelche
eigenen Schlüsse aufgrund Ihrer Messergebnisse.
