6.8 multiparameter monitor (optional)

To view the sensor-acquired waveform on your patient monitor, you will need a brain4care BcAc-DG-1000 dongle adapted for invasive pressure inputs on patient monitors.

There are two ways to pair the sensor with the receiver: manual pairing or in app guided pairing.

6.8.1 manual pairing

Step 1 - Connect receiver (dongle)

Connect the receiver/dongle (nr.1) to the invasive pressure input on the patient monitor (nr.2) and make sure.

Step 2 - Position sensor on patient

Turn on the sensor and position it on the patient as explained in sections 6.3 logging into app and 6.6 positioning sensor on patient

Step 3 - Initiate dongle-sensor pairing

To start the pairing process, press the interface button on the BcAc-DG-1000 dongle (nr.1), and make sure that the receiver LED flashes blue. Then press the sensor interface button (nr.2) and verify that the LED also is flashing blue.

Step 4 - Verify matching devices

Shortly thereafter, both devices will enter pairing intelligence mode, with visual LED confirmation. Both the sensor and receiver will flash with a random matching color and frequency pattern, meaning that both have identified each other and are able to match.

Step 5 - Confirm matching devices

The pairing is completed by pressing the button on one of the devices (button 1 or button 2 in Figure 6.8-2). When this is done, the matching lights will flash green three times, informing a successful pairing. If you do not want to complete pairing, wait a few seconds for both devices to go into standby mode.

Step 6 - Verify waveform in patient monitor

With pairing is complete, the sensor waveform should appear on the multiparameter monitor. For best viewing, set the patient monitor to automatic scaling. If the signal is not found on the multiparameter monitor, turn off the sensor, unplug the receiver, and return to step 1.

6.8.2 in app guided pairing (available in app version 2.8 or older)

In this pairing method, the B4C System mobile app will make the connection between the dongle and the sensor. A major benefit of this method is the ability to view the sensor waveform both on the mobile app and patient monitor and also the ability to generate a monitoring session report (please view section 6.7 b4c report for details on the generated report)

Step 1 - Connect receiver (dongle)

Connect the receiver/dongle (nr.1) to the invasive pressure input on the patient monitor (nr.2) and make sure.

Step 2 - Log into app and pair sensor

Log into app and pair sensor as explained in section 6.3 logging into app

Step 3 - Initiate dongle pairing in mobile device

After pairing the sensor, in the application, click “Pair Receiver.” A list of available receivers will appear.

Check the receiver’s UDI on the label opposite to the button… (see item 1 in figure 6.8-4)

…and then select it from the list (item 1 in figure 6.8-5). Some receivers may not be available to be clicked, represented in gray, as they are not active, locked, do not belong to the organization (corporate account), or are awaiting activation (if your sensor is grayed out, check with your clinical engineering team).

Step 5 - Verify matching devices in app

After selecting the dongle, the pairing intelligence mode between sensor and receiver will start, with a visual LED confirmation on both devices. Visually confirm the pairing with the physical receiver (Figure 6.8-6), with the receiver image in the mobile app. Both should be flashing matching color and blinking patter. Click “Confirm” to continue pairing (item 1 in figure 6.8-6). If the pattern is not identified or you want to change the receiver, simply click on “Reselect”.

Once the connection with the dongle is confirmed, you will be directed to the screen on Figure 6.8-7, where the sensor, receiver and application are paired. The same pairing intelligence method is done with the sensor, receiver, and mobile application screen by flashing in the same randomly generated color and frequency pattern.

Step 6 - Confirm dongle pairing

Verify that all three devices have the same flashing pattern and click “Confirm” (item 1 Figure 6.8-7). If the pattern is not identified or you want to change any of the devices, just click “Reselect”. (Figure 6.8-7)

The sensor and receiver status LEDs will flash green three times as soon as pairing is confirmed, and a success window will appear in the application.

Step 7 - Verify signal on patient monitor

At this point, the multiparameter monitor should start receiving the signal from the waveform. For best viewing, set the patient monitor to automatic scaling. If the signal is not found on the multiparameter monitor, turn off the sensor, unplug the receiver, and return to step 1.

Remark: If in addition to viewing on the patient monitor you also want to have a generate the report in the mobile application, click on “Start monitoring” and proceed to section 6.6 monitoring the patient . If you just want to monitor on the multiparameter monitor, click “Cancel”.

6.8.3 verifying the ni-ICP signal quality in patient monitors using receiver

After correctly placing the sensor on the patient’s head and pairing with the dongle the waveform should appear on the patient monitor. Good positioning of the headband and proper placement of the sensor will result in typical waveform as depicted below (Figure 6.8-8). Note: the figure below is simply an illustration of a sample waveform.

If the signals shown on the monitor do not present any of the characteristics seen in the depiction above (the signal should at least present identifiable P1 and P2 peaks), modify the position of the sensor on the patient’s head by shifting and/or tightening/ loosening the headband until a satisfactory pulse waveform is obtained. An example of a poor reading is depicted below (Figure 6.8-9).
