Mindray ePM 10M User Manual

20 - 7
• Switching the auto impedance check off will disable automatic prompt to the user of impedance
value changes, which may lead to incorrect BIS values. Therefore, this should only be done if the
check interferes with or disturbs other measurements.
20.8.3 Manual Sensor Check
To manually start a sensor check, use either of the following method:
■ Press the sensor check hardkey on the BIS module.
■ Select the Sensor Check tab from the BIS menu.
The monitor enters the sensor check window after you start the sensor check. The sensor check window displays
the following items:
■ Sensor Type
■ The status of each electrode
■ Expiration time or usable cycles
NOTE
• For different types of sensors the sensor check window may be different.
20.8.4 BIS Sensor Status
The color of each electrodes indicates its status:
Although BIS may still be measured when the electrode status is Noise or High, for best performance, all
electrodes should be in Pass status.
The sensor check may fail for the following reasons:
■ Impedance too high
■ Incorrect sensor application
■ Poor sensor connection
■ Defective patient interface cable or sensor
To correct the situation:
■ Recheck the sensor
■ Reapply the sensor according to instructions
■ Check sensor connection
■ Replace patient interface cable or sensor
20.9 Monitoring Bilateral BIS
By using BISx4 and the Bilateral sensor you can perform bilateral BIS monitoring. You can display the BIS expand
view during bilateral BIS monitoring.
Color Status Description Action
Red Lead off Electrode falls off and has no skin
contact
Press the sensor more firmly to skin to ensure
good sensor-to-skin contact. If necessary,
remove the sensor, and then clean and dry the
skin. Reapply the senor or replace the sensor.
Grey Noise The EEG signal is too noisy. Impedance
cannot be measured
Press the sensor more firmly to skin to ensure
good sensor-to-skin contact.
Yellow High The impedance is above the limit Press the sensor more firmly to skin to ensure
good sensor-to-skin contact.
Green Pass The impedance is within valid range No action necessary.
