Attention
Measurement errors
•
The use of components not included in the scope of delivery may lead to measurement errors because
alternative transformers and cables, for example, can result in increased electromagnetic interference
emissions or reduced electromagnetic interference immunity. You should therefore only use genuine Welch
Allyn accessories.
•
Although the ABPM 7100 meets all EMC standards, you should nonetheless avoid exposing it to strong
electromagnetic fields, as this may cause malfunctions outside the tolerances for the device. You should
therefore ensure that the ABPM 7100 is at least 30 cm (12 inches) from any portable RF communications
equipment.
•
Electrical medical devices are subject to specific EMC precautions. Please ensure that you adhere to the
relevant guidelines.
•
The cuff tubing between the ABPM 7100 and the cuff may not be knotted, compressed or pulled apart.
•
The cuff connection must always engage with an audible “CLICK”. A loose connection between the tubing and
the device leads to measurement errors.
Initial measurement
Note
•
Severe malfunctions are indicated by a continuous beep.
•
In the event of a continuous beep, switch off the device, remove the cuff and inform your
doctor.
•
Hand the data sheet “Patient information – operation of the ABPM 7100” to each patient.
The data sheet is attached as a copy template.
•
Portable and mobile RF communication equipment may influence medical electrical
devices.
•
Extreme temperatures, humidity or air pressure can influence measurement accuracy.
Please observe the operating conditions.
•
There are currently no clinical studies against reference methods available at respect to
the application of pulse wave analysis on children.
•
The pulse wave analysis provides additional indicators for possible risks, but is not
permissible as a sufficient indicator for individual illness or as a treatment
recommendation.
•
External distorting factors such as movement of the arm used for the measurement,
physical activity or, for example, driving or using public transport during a measurement
may lead to motion-related artefacts or incorrect measurements. For this reason, the
activity log kept by the patient must be viewed and considered in the assessment of the
measurements.
•
An internal reboot may occur. In this case, the device will start in the most recently used
operating status.
This may be caused by internal or external influences, such as electrostatic discharges
from clothing, or because the internal memory battery is empty. If the internal memory
battery is empty, this error will occur when the external battery is replaced. You should
therefore please contact your dealer.
Note
•
An initial measurement is required for starting the measurement log. The initial
measurement must be checked by a physician for plausibility!
Measurement process - 28
24-hour measurement
1. Ensure sufficient battery voltage. At least 2.6 volts for NiMH batteries and at least 3.10 volts for alkaline
batteries!
2. The doctor must go through these instructions together with the patient before a 24-hour measurement.
3. The doctor must explain the possible hazards in detail on the basis of the warnings above!
4. Ensure that the patient has understood all functions and observable points!
Safety:
For your own safety during the following steps, please observe the safety instructions at the
start of this chapter, as well as the functional overview.
Performing a measurement
1. To trigger a measurement, press the START button.
•
The number of stored measurements will be shown on the LCD display.
•
An audio beep will announce the upcoming measurement.
•
Manual measurement will start.
2. The patient should stay calm during the measurement process, until the measurement is completed. Allow
your arm to hang loose, or place your lower arm loosely on the table or on a support whilst sitting. Avoid any
movement!
3. Doctor: Please check the values of the first measurement for plausibility, so that subsequent automatic
measurements can be processed correctly and correct cuff position is ensured.
4. In the event of an error measurement, please follow the instructions in sections Measurement preparations
and Troubleshooting .
Cancelling a measurement
A measurement will be cancelled by pressing any buttons during the measurement process. The LCD display will
then show
-StoP- and the ABPM 7100 will beep 5 times. This cancellation will be stored in the measurement value
table under Cancel .
If terminated, another measurement will be started after three minutes.
Unsuccessful measurement
1. If the display shows errors, reexamine the correct procedure during set-up and positioning of the device.
2. Dismiss the patient only after a successful manual measurement!
Inform the patient sufficiently in order to explain the situation!
3. Repeat the measurement.
4. If the display still shows errors, repeat the initial operation process.
5. For further troubleshooting measures and faults removal, please refer to the
Troubleshooting section.
Note
•
Severe malfunctions are indicated by a continuous beep.
•
In the event of a continuous beep, switch off the device, remove the cuff and inform your
doctor.
