Artefacts
IoC is higher than expected
Check the patient cable.
Replace the battery or connect the power
supply.
Connect the Bluetooth
Check if either of the sensors are
disconnected or badly connected.
Replace faulty sensor
Sensor impedance too high.
If sensor impedance is >15kΩ the IoC index,
ESI and EMG will be blanked.
Check that sensors are not dry.
Check that the skin has been cleaned
properly.
Poor impedance conditions may cause the
SQI to fall to 50%.
Check that the electrodes are correctly
connected.
Artefacts can have many causes: diathermy,
EMG, etc.
Move the device away from the sensors.

Some patients require a higher dose of drugs
due to inter-patient variability.
Adequate dosing for maintenance may not
be sufficient for increased stimulation.
