d) Tighten the free end of the cuff and close the cuff

with the closer.

e) There must be no free space between the arm and

the cuff as this would influence the result. Clothing

must not restrict the arm. Any piece of clothing which

does (e.g. a pullover) must be taken off.

f) Secure the cuff with the Velcro closer in such a way

that it lies comfortably and is not too tight. Lay the

arm on the table (palm upwards) so that the cuff is at

the same height as the heart. Make sure that the tu-

be is not kinked.

g) Remain seated quietly for two minutes before you

begin the measurement.

Comment:

If it is not possible to fit the cuff to the left arm, it can

also be placed on the right one. However all measure-

ments should be made using the same arm

5.4. Measuring procedure

After the cuff has been appropriately positioned, the

measurement can begin:

a) Switch on the instrument by pressing the O/I-Memory

button. The tube should not yet be attached to the

instrument. The following appears in the display for 2

seconds: (Diag.)., A short be-be-beep follows to

indicate that the instrument has equilibrated with the

pressure of the surroundings and the measurement

can therefore begin. A «0» is shown in the display.

b) Plug the T-connecting piece or the free end of the

tube into the left-hand side of the instrument.

c) Grasp the pump ball with your free hand and Inflate

the cuff to a pressure at least 40 mmHg higher than

the expected systolic pressure. If you do not know the

value of this pressure, inflate to a value of

approximately 160–180 mmHg. The cuff pressure is

shown continuously on the LCD.

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 quite

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.

5.3. Fitting the cuff

a) Pass the end of the cuff (with sewn-in rubber stopper)

through the metal stirrup so that a loop is formed.

The Velcro closer must be facing outwards. (Ignore

this step if the cuff has already been prepared.)

b) Push the cuff over the left upper arm so that the tube

points in the direction of the lower arm.

c) Lay the cuff on the arm as illustrated. Make certain

that the lower edge of the cuff lies approximately 2 to

3 cm above the elbow and that the rubber tube leaves

the cuff on the inner side of the arm.

Important! The mark (ca. 3 cm long bar) must lie

exactly over the artery which runs down the inner

side of the arm.

2–3 cm
