Setting Entropy alarms
Entropy
1. Press the module key, or press the
Entropy
2. Select Entropy Alarms.
3. Select Adjust Limits to set up the limits.
4. Select RE Alarm, SE Alarm to OFF/ON the limits.
5. You can also select Alarms Setup to adjust Entropy or related
alarms.
Stopping the Entropy measurement
1. Remove the Entropy sensor from the patient.
2. Disconnect the sensor from the sensor cable.
3. Discard the sensor.

Entropy values seem unstable:
−
Check that the sensor is not dried out.
−
Check the sensor attachment and placement.
−
Check the patient status.
Entropy EEG signal is noisy:
−
Remove disturbing equipment from the proximity of the
Entropy module or sensor.
−
Check the sensor's contact with skin.
−
Check electrodes.
Entropy EEG signal is poor:
−
Check the sensor's contact with skin.
−
Check electrodes.
Entropy waveform and numbers do not correspond:
−
Check raw EEG as impedance check may cause a temporary
increase in the numeric values.
−
Check the patient's overall status.
Entropy readings seem inconsistent with the patient status:
−
Check raw EEG for QRS or other artifact.
−
Check electrode placement.
