Preparing for Entropy measurement
1. Connect the Entropy sensor cable to the module.
2. Clean the application site according to the sensor's instructions
for use and let it dry before attaching the sensor.
3. Place the Entropy sensor on the patient's forehead; see sensor
package for instructions.
4. Connect the sensor to the Entropy sensor cable.
5. Observe the results of the automatic sensor check in the
parameter window.
6. The measurement starts automatically after the sensor has
passed the check.
Entropy points to note
• Entropy sensors are latex- and PVC-free, disposable and for
single-patient use only.
• Make sure that the sensor connectors of the sensor cable are
not in contact with fluids.
• Always ensure that the sensor is properly attached to the patient
and connected to the cable.
• In NEONATAL mode, the entropy function will be disabled and
the related menu is gray.
Entropy measurement checks
• Check that the sensor/electrode passes the sensor/electrode
check when you are starting to monitor a new patient.
Selecting the EEG scale
This selection affects the Entropy waveform and snapshots:
Entropy
1. Press the
Entropy
2. Select Entr.EEG Scale.
3. Select a value from the scale list.
Selecting the Entropy trend length
Entropy
1. Press the
Entropy
2. Select Trend Length and choose an option.
This option only influences the length of the trend shown in
horizontal digit field.
Selecting the display format for Entropy
You can select which Entropy parameters are shown in realtime,
trends, recording and printing.
Entropy
1. Press the
Entropy
2. Select Display Format and choose an option.
• RE = Response Entropy
• SE = State Entropy
• RE+SE = both of the above
• All = RE, SE and Burst Suppression Ratio (BSR)
