3-18 BeneVision N22/BeneVision N19 Patient Monitor Service Manual
3.4.12 BIS Test
You can choose either of the following methods to perform the test:
Method 1:
Tools required:
None.
1. Connect the BIS sensor to a healthy, wide-awake adult as directed in the Operator's Manual.
2. Check the EEG wave and BIS numerics displayed on the screen and make sure the BIS value is within 80 and 100.
Method 2:
Tools required:
BIS simulator (Covidien PN: 186-0137)
1. Connect the BIS sensor with the BIS simulator. Select BIS area parameter or waveform to access BIS Setup. Then,
select Sensor Check to perform a cyclic impedance check.
2. After the cyclic impedance check is finished, check that the result for each electrode is passed.
Method 3:
Tools:
Signal generator, （Maker: NF, Model:WF1946B）
Covidien Signal simulator (Covidien PN:189-0137)
1. Insert the BIS module to the monitor, connect the BIS module/cable to the Covidien Signal simulator, signal
generator.
2. Adjust the signal generator to produce a 90Hz, 35.4mV(RMS) sine signal to the Convidien Signal simulator.
3. Set the time length of the review window to the shortest.
4. Verify the EMG value range from 65 to 75, and SQI value should be 100 displayed on Graphic Trends.
3.4.13 CCO/SvO
2
Tests
Interconnecting Function
Tools required:
None.
1. Connect and set the patient monitor and Vigilance monitor per the procedures in the Operator's Manual.
2. Set the Vigilance monitor to Demo mode. Start the CCO and SvO2 tests in Demo mode.
3. Verify that the CCO/SvO2 numerics displayed on the patient monitor and Vigilance monitor are consistent.
