Patient Monitor User Manual Alarm Information
- 65 -
Message Cause Alarm Level Action Taken
BIS Sensor Expired
The sensor expired. Low
The sensor can be
used as long as it
passes the
impedance check,
which, however,
may affect the
measurements.
Replace the sensor
if necessary.
BIS No More Uses
For This Sensor
The sensor has been used
too many times and cannot
be used any more.
Low Replace the sensor.
BIS High Impedance
The impedance is above the
limit
Low
Check the
senor-to-skin
contact.
BIS Lead Off
Electrode has no skin
contact.
Low
Check the
senor-to-skin
contact.
BIS Noise
There is electrical
interference.
Low
Check the
senor-to-skin
contact.
Bad BIS SQI
SQI < 15 Medium
1) Check the
senor-to-skin
contact.
2) The SQI value
will be influenced
by impedance check
for the ground
electrode and sensor
check.
Poor BIS SQI
15 ≤ SQI < 50 Low
1) Check the
senor-to-skin
contact.
2) The SQI value
will be influenced
by impedance check
for the ground
electrode and sensor
check.
