EEG Signal (Errors 25 and 26):

Note: These messages relate to the condition of the EEG signal. This signal is often affected by environmental conditions that cause artifact (non-EEG signal). The messages below do not usually indicate a monitor system error; instead they serve as a notification of a patient or environmental condition.

Status Messages:

Causes:

Corrective Actions:

E25
Left Side SQI Bad

 With 2-channel montage, left side signal quality is bad.
  1. Artifact is causing EEG information to be lost
  2. EMG Bar indicates electrical activity that may be interfering with EEG recognition.
  3. PIC is defective.
  4. DSC is defective.
Note: This message may occur as the result of artifact (non-EEG signal) such as those generated from motion (patient movement) or the presence of electro-cautery or other devices.
  1. If ARTIFACT label appears in EEG waveform box, attempt to identify and eliminate artifact source.
  2. If EMG is present, try to determine and eliminate cause.
  3. Verify Sensor Check passes. If not, replace PIC.
  4. Replace DSC

E26Right Side SQI Bad

 With 2-channel montage, right side signal quality is bad.
  1. Artifact is causing EEG information to be lost
  2. EMG Bar indicates electrical activity that may be interfering with EEG recognition.
  3. PIC is defective.
  4. DSC is defective.
Note: This message may occur as the result of artifact (non-EEG signal) such as those generated from motion (patient movement) or the presence of electro-cautery or other devices.
  1. If ARTIFACT label appears in EEG waveform box, attempt to identify and eliminate artifact source.
  2. If EMG is present, try to determine and eliminate cause.
  3. Verify Sensor Check passes. If not, replace PIC.
  4. Replace DSC

E27
SQI Below 50

 The Signal Quality Index is less than 50 and the numeric display changes from a solid to an outlined number.This may occur as the result of artifact such as those generated from motion or eyeblinks.
  1. Re-prep the sensor.
  2. Check impedance.

E28
SQI Too Low for BIS

 The Signal Quality Index is unacceptable. The Primary Trend variable cannot be calculated and therefore the numeric display is blanked.
  1. Artifact, such as those generated by motion or eyeblinks, is causing loss of EEG recognition.
  2. EMG Bar indicates electrical activity that may be interfering with EEG recognition.
  3. PIC is defective.
  4. DSC is defective.
Note: This message may occur as the results of artifact (non-EEG signal) such as those generated from motion (patient movement or eyeblinks) or the presence of electro-cautery or other devices.
  1. If ARTIFACT label appears in EEG waveform box, attempt to identify and eliminate artifact source.
  2. If EMG bar is illuminated, attempt to determine and eliminate cause.
  3. Verify Sensor Check passes. If not, replace PIC.
  4. Replace DSC

E29
BIS < Low Alarm Limit

 The BIS has fallen below the low alarm limit set by the user. The numeric display flashes. Take note of BIS at limit set by user.

E30
BIS > High Alarm Limit

 The BIS has risen above the high alarm limit set by the user. The numeric display flashes. Take note of BIS at limit set by user.

E31
Isoelectric EEG Detected

 No discernible EEG activity is detected for several minutes; SR=100.Note: This message notifies user of a flatline EEG. This is a normal condition when Sensor Simulator or Test Sensor is connected.
  1. Check the patient
  2. Check leads for proper connection and possible shorts.
  3. Verify Sensor Check passes.
  4. Verify DSC - Self-test
  5. Verify PIC Use Test Sensor or Sensor Simulator and Sensor Check.

E32
