4.2. Tube connection

Cuff AC-1 (1-tube cuff + T-connector):

Set up (or check) the tube connections between cuff,

instrument and pump ball as shown in the diagram.

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 5 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.

5.3. Fitting the cuff

a) Push the cuff over the left upper arm so that the tube points

in the direction of the lower arm.

b) 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.

c) Tighten the free end of the cuff and close the cuff with the closer.

d) There must be no free space between the arm and the cuff

as this would inﬂuence the result. Clothing must not restrict

2-3 cm
