The Buttons

ON/OFF

The ON/OFF button turns the ABPM 7100 on and off. To prevent unintended activation, the ABPM 7100 turns on or turns off only when the button is pressed for more than 2 seconds.

START

The START button serves to

  • initiate a manual measurement to ascertain whether the ABPM 7100 is working correctly.
  • initiate a 24-hour measurement.
  • perform a measurement outside the specified measurement cycle.

DAY/NIGHT

The DAY/NIGHT button is used to differentiate between waking and sleeping phases during the measurement, which is important for statistics and the graphic displays.

The patient is instructed to press the DAY/NIGHT button upon going to bed and again, when getting up in the morning. This individually adapts the measurement interval to the patient and assists you in the analysis of the blood pressure profile.

EVENT

The patient uses the EVENT button to document the time of medication or to record any events which may cause the blood pressure to rise or fall. Pressing the button will trigger a measurement, the patient should note the reason for pressing the EVENT button in the event log.

LCD Display

The LCD display is located on the front of the ABPM 7100 casing. It displays useful information for the doctor and the patient regarding measurement data, monitor settings and measurement errors. When the START button is pressed, the number of previously registered measurements will be shown before starting a manual measurement.

Audible signals

Individual or multiple beeps of audible signals are used. The following table explains the meaning of the beeps:

1 beep
  • Switching ON/OFF
  • Starting and ending a measurement (except at night intervals)
  • Removal of the interface cable
  • Establishing and ending Bluetooth® communication
  • Measurement errors
3 beeps
  • System errors
Continuous beeps
  • Severe system errors (e.g. cuff pressure is higher than 15 mmHg for longer than 10 seconds outside the measurement)
Combined beeps
  • Manual deletion of measurement, 1 beep followed by 5 beeps 2 seconds later

Cuff connection

  • The cuff connection is located at the top of the ABPM 7100 casing.
  • The cuff is connected to the ABPM 7100 via a metal connector.

Measurement errors

  • The cuff connection must always engage with an audible “CLICK“. A poor connection between the ABPM 7100 and cuff will result in measurement errors.

Technical Data

Accessories

Preparing the ABPM 7100

Inserting the batteries

Device function

  • Although zinc-carbon batteries may indicate sufficient voltage during a battery test, their output is frequently insufficient to perform 24-hour measurements. Ensure sufficient battery voltage. At least 2.6 volts for NiMH batteries and at least 3.10 volts for alkaline batteries!

Damage to device

  • Do not open the casing. Once the device is opened, all warranties will lapse.

Open the batteries compartment on the rear of the ABPM 7100 casing to insert the batteries into the ABPM 7100 according to the battery polarities (+ / -) and close the compartment.

Internal memory battery

  • If after changing the external battery the display shows “rEboot”, the internal memory battery may be empty. Please contact your dealer.

Activating the device

Attention

Damage to device

  • Do not wear the ABPM 7100 while showering. If you suspect that liquid has entered the device while cleaning or using it, the device shall no longer be used on the patient.
  • If the device was exposed to moisture, switch off the device and remove the batteries.
  • Inform your service immediately and send the device in for inspection.
  • The device may not be operated around MRI scanners or in the immediate vicinity of other medical electrical equipment.
  • During a defibrillator discharge, the device shall not be in contact with the patient. Such a discharge may damage the ABPM 7100 and cause it to display incorrect values.
  • This device should not be used directly adjacent to other devices or stacked with other devices, as this may result in malfunction. If it is nonetheless necessary to operate the device in the manner described above, you should observe this and the other devices during use and convince yourself that they are working properly.
  • The ABPM 7100 is not suitable for simultaneous use with HF surgical equipment.
  • Measurement can be interrupted at any stage by pushing a random button. This deflates the cuff and the device can be removed

Attention

Hygiene

  • Ensure hygiene in accordance with the maintenance schedule.

Always check the condition of the ABPM 7100 by observing the initial display shown on the device shortly after turning it on and before handing it to a patient. The ABPM 7100 performs a self-test. In addition, a beep sounds to check the speaker. The following should be displayed in this sequence:

If the internal test detects an error, the ABPM 7100 will indicate “E004” on the display and emit an audible signal. For safety reasons, the use of the ABPM 7100 will be locked. The faulty ABPM 7100 unit should be send back immediately for repairs to your dealer or to Welch Allyn.

Setting the time / date

The ABPM 7100 has an internal buffer battery allowing the time to continue even if the batteries have been removed. Nevertheless the time and the date should be checked before every measurement series.

The time and date can be set automatically with the patient management software.

Alternatively the time and date can be set manually. Press and hold the START button and then press the EVENT buttons to enter the Set Time mode. Use the START button to select the appropriate item and use the EVENT button to jump to the next display item.

Clearing the memory

The device memory must be cleared before every measurement series, i.e. blood pressure data form the previous patient must not remain in the memory.

If there are existing data, the memory can be cleared with the delete function of the analysis software.

Alternatively the data can be cleared manually. Press and hold the START button for a minimum of 5 seconds until “cLr” is displayed. Within the next 5 seconds press and hold the EVENT button for at least 2 seconds to confirm the deletion of the stored measurements. The device emits a single beep to indicate that the memory is cleared.

Transferring patient data (ID)

The ABPM 7100 must be prepared by transferring patient data (ID) with the help of the patient management software, so that correct data allocation is possible when it is read out after measurement. Please refer to the respective patient management software manual for how to transfer patient data (ID) to the ABPM 7100.

Setting measurement logs

In the patient management software you can optionally choose between eleven (1-11) logs. A log serves to set the measurement intervals. As soon as you have conducted a measurement, the log can only be changed once you have fully deleted all data.

Manual log settings

For manual log setting, press and hold the DAY/NIGHT button while simultaneously pressing the EVENT button. Use the START button to change the log and confirm with the EVENT button.

Setting the logs via software

To set the logs via software please refer to the respective patient management software manual.

Note

  • Logs 1, 2, 10 and 11 are set by default but can be changed via the patient management software
  • Log 5 is suitable for nighttime activities (night shift)
  • Log 9 is designated as “Schellong-Test”.
  • Log 10 automatically sends the measurement values to your doctor’s PC via Bluetooth®. Bluetooth® communication is not supported with the CPWS software.
  • Log 11 is only available to upgraded ABPM 7100 systems in connection with HMS from version 5.0. Blood pressure measurement intervals and the 24h PWA can be set separately here. Please contact Welch Allyn for further information.

Selecting a suitable cuff

Caution: Risk of injury caused by incorrect application of the cuff.

  • The doctor must ensure that, due to the patient’s medical condition, the use of the device and the cuff does not result in impaired blood circulation.
  • If the patient is has limited cognitive abilities, the device may only be used under supervision.
  • When used on children, the device must only be applied with special care and under permanent supervision.
  • It is imperative that you instruct the patient in the correct seating of the cuff.
  • Inform the patient that the cuff may only be used on the upper arm.
  • Ensure that neither the shoulder strap nor the cuff tubing can ever wrap around the patient’s neck. Always place the cuff tubing under the outer clothing (even at night).
  • Instruct the patient to place the device in such a way that, while the cuff is inflated, the tubing is not compressed or kinked, especially during sleep.
  • Petechiae, haemorrhages or subcutaneous haematoma may occur in some patients.
  • Instruct the patient to turn off the device, remove the cuff, and notify the doctor if they are experiencing pain, swelling, redness or numbness in the limb where the cuff is placed. (It is expected that the patient may experience some mild to moderate discomfort during a blood pressure measurement.)

The correct cuff size is important for correct blood pressure measurement. To obtain reproducible measurements, standardized measuring conditions are needed. Measure the circumference of the upper arm and select the appropriate cuff:

Applying the ABP Monitor and cuff:

  1. Position the carrying pouch on the right side of the patient. By varying the length of the pouch strap, it can be worn around the hips or around the shoulders.
  2. Alternatively a normal belt matching the clothes can be used.
  3. Fit the cuff onto the patient. The correct cuff seating is very important for correct blood pressure measurement.
  4. Align the cuff so that no part of the cuff tubing is kinked. In this regard, the tube connection on the cuff must face upwards.
  5. Align the cuff so that the lower edge of the cuff is approximately 2 cm (0.8 in) above the inside of the patient’s elbow.
  6. Tighten the cuff around the upper arm until one finger can be introduced under the cuff.
  7. It is imperative that the artery symbol is positioned on the brachial artery. If you have aligned the cuff correctly, the metal bar will lie on the outside of the upper arm (on the elbow side), whereby the cuff sleeve must cover the skin under the metal bar.
  8. Guide the tubing through the shirt’s row of buttons and out of the clothing, behind the nape of the neck to the ABPM 7100 on the right side of the body.
  9. The cuff can be worn on the naked upper arm or over a thin shirt sleeve.
  10. The placement of the pressure tube must guarantee the upper arm’s free motion.

Connecting the cuff tubing to the ABPM 7100

  1. Push the tube firmly onto the connection, with the cuff tubing engaging with an audible “CLICK” (to detach, simply pull back the knurled ring).
  2. Before measurement, check to ensure that tubing, ABPM 7100 and cuff are positioned correctly. The ABPM 7100 is ready for measurement only once this is ensured.
