BIS™ Advance Monitor
patient’s skin may help the electrode
pass the sensor check.
The sensor check will determine if the sensor will pass the sensor check based on the
impedance of the electrodes and the ground electrode.
If the sensor passes the sensor check, monitoring will begin automatically. If the
sensor fails, monitoring will not begin. If the sensor does not pass the sensor check
process, check the functionality of the PIC cable by running a sensor check using a
Sensor Simulator. If the sensor check does not pass with the Sensor Simulator,
replace the PIC or the BISx module. If the sensor check passes with the Sensor
Simulator, replace the sensor with a new appropriate sensor. That sensor will then
undergo an automatic sensor check upon attachment. If it passes the sensor check,
monitoring will commence.
For the 2-channel system, the electrodes will be labeled as follows, starting from the
left-most electrode when viewing the sensor from the front: 1,2,4,3.
For the 4-channel system, the electrodes shall be labeled as follows, starting from the
left-most electrode when viewing the sensor from the front: LT, LE, G, C, RE, RT.
The user can determine if he wants to display the sensor check values or just a PASS,
HIGH, NOISE or POOR CONTACT indicator. By default, Display Sensor Check Values is
disabled, so PASS, HIGH, NOISE or POOR CONTACT will appear for each sensor
section. To enable sensor check values, reference 3.15.3.4 Sensor Check Values on page
134.
If the sensor is supported and impedance values are in the acceptable range, the
system shall display patient data based on the information collected by the sensor. If
there are issues that prevent the system from reading information from this sensor,
an on-screen message will display this information.
