Location Explanation What to do
●
Isoelectric EEG
●
param.,
wavef.
Isoelectric (flatline) EEG detected
in Entropy measurement.
●
Check the patient status. The
patient’s anesthetic status
may be unnecessarily deep.
●
Low signal
●
param.
Measured EEG signal is too low
for reliable Entropy calculation.
●
Check sensor placement.
●
The patient may be in total
suppression; check the
patient status.
●
No Entropy sensor
●
al. area The sensor is not connected to
the cable, or the sensor and
cable are not compatible.
●
Check connection between
Entropy sensor and cable.
●
Check that the cable and
sensor are compatible.
●
No sensor
●
al. area The sensor is not connected to
the cable, or the sensor and
cable are not compatible.
●
Check connection between
Entropy sensor and cable.
●
Check that the cable and
sensor are compatible.
●
Noise
●
wavef. Unreliable Entropy calculation
or distorted EEG waveform may
appear during electrosurgery or
other high frequency noise.
●
Interpret Entropy values with
caution.
●
Sensor check failed
●
param.
The sensor has not passed the
impedance check.
●
Check sensor placement and
attachment.
●
Confirm proper contact of
each electrode in the sensor.
●
Replace the sensor.
●
Sensor off
●
param.
The sensor is connected to the
cable but not attached to the
patient, or the sensor type is not
correct.
●
Check that the sensor is
properly attached to the
patient.
●
Check that the sensor is an
Entropy sensor.
●
Starting up
●
param.
The monitor is collecting data to
start the measurement.
●
Wait for about one minute.
Entropy values appear
automatically.
