Please note the following points:
IMPORTANT:
1. When putting the recorder on the patient, the recorder must not be connected to other external equip-
ment!
2. The cuff must fit so that the air tube cannot be kinked or compressed at any point. The tube connection
on the cuff should therefore be directed upwards. The air tube should allow free movement of the upper
arm and should run over the back of the neck to the other side of the body.
3. It is essential to ensure that the artery symbol lies over the brachial artery. When the cuff fits correctly, the
metal strip is on the outer side of the upper arm (elbow side).
4. The material loop must cover the skin under the metal strip.
5. The lower edge of the cuff should be about 2 cm above the bend of the patient’s elbow.
6. The cuff should fit relatively snugly on the upper arm. Correct fit can be checked by a simple test: there
should be room to slip one finger under the cuff.
7. The correct cuff size is also important if blood pressure is to be measured correctly. To obtain reproduc-
ible results, standardised monitoring conditions are required, i.e. the cuff must be the correct size for the
patient. Using the tape measure supplied, measure the circumference at the middle of the upper arm and
select the appropriate cuff:
Upper arm circumference
Cuff
14 - 20 cm
XS
20 - 24 cm
S
24 - 32 cm
M
32 - 38 cm
L
38 - 55 cm
XL
8. Connect the air tube from the cuff to the ABP recorder. Push the tube firmly over the connection until a
click is heard as it engages; to disconnect, simply pull back the outer metal ring on the plug.
9. The recorder is now correctly fitted and ready for use.
Once all these steps have been completed, the monitor can be started. First, a manual measurement must be
carried out by pressing the “START” key. This measurement is used to determine whether the recorder is work-
ing correctly.
If errors occur, check once more that the procedure followed in setting up and fitting the equipment was correct.
Should this not solve the problem, repeat the setting-up procedure.
Only after a successful manual measurement can the patient be allowed to leave with the equipment.
Interrupting measurements
During a measurement,
ANY
key can be used to interrupt the measurement. The display then shows “-StoP-”
and beeps 5 times. The process is also saved in the table of measurements under “Interruption”.
Important: Before beginning a 24-hour monitoring session, take the patient through Chapter 2:
