Unique cfm
Quick Set-up Guide
Prior to operation: Refer to Instructions for Use.
You will need:
PC / Monitor (running Windows XP or 7 software)
Unique CFM
Headbox
Electrodes (choice of Needle or Hydrogel)
Optional:
USB Video camera
Skin Preparation Gel such as Nu-Prep
(for use with Hydrogel electrodes)
Adhesive tape (for use with Needle electrodes)
SETUP AND RECORD
Plug the PC / Monitor cable cord in to the rear socket
and connect to the mains electricity, and turn on.
Turn on CFM amplifier module.
Note: Monitor and amplifier module will pair automatically
via Bluetooth. A low beep will confirm pairing. If pairing is not
established refer to the user manual.
Check battery power level on amplifier module is adequate,
plug in to the mains supply to charge if required.
Clip the selected headbox in to the amplifier module.
Connect electrodes to patient (see Electrode Placement section for correct placement).
Connect electrodes to the headbox by pushing them all the way down to the hub.
Press New Patient button on screen.
NEW PATIENT
Note: If entering a new patient enter the relevant information.
(Minimum information: Patient Identification Number) using the onscreen keyboard.
Click on Append Record to continue recording on an existing patient file.
Select OK to enter Preview mode.
Note: In Preview you can run an impendence check to test the electrode
connection. Click on IMP.
Click on Record button to start recording.

TREATMENT GUIDE
aEEG (amplitude integrated electroencephalography) provides a trend over time of
the electrocortical background activity of the brain. Unique CFM displays the aEEG.
Below is a basic interpretation guide for aEEG traces.
Normal
Moderately abnormal
ONSCREEN TOUCH NAVIGATION
In Record
Adjust EEG and aEEG scale using
the scroll keys on the left panel.
Enter a predefined marker.
Free text marker.
Resize Screen, useful if using the
multipatient mode.
Alarm Silencer, for high impedance
and high aEEG amplitude.
Drop in a marker with
no description.
Switch between CSA and DSA.
REVIEW
Click to review patient data.
PAUSE
Pause recording to return to Preview mode.
aEEG (CFM) will show an Upper Margin of
>10 µvolts and a Lower Margin >5µvolts.
aEEG is characterized by Sleep/Wake
cycles.
aEEG (CFM) will show an Upper Margin
of >10 µvolts and a Lower Margin <5µvolts
and is characterized by an increase in
inconsistent erratic activity.
No Sleep/Wake Cycles in aEEG (CFM).
Severely abnormal
Seizures
In Review

To view all entered markers. Click on a specific marker to be taken to
the correct part in the recording.
aEEG (CFM) will show an Upper Margin
of <10 µvolts and is characterized by a
reduction of activity.
aEEG (CFM) shows the injured brain
has increased continuous high activity.
No Sleep/Wake Cycles in aEEG (CFM).
EEG is predictable and consistent.
aEEG (CFM) to narrow and rise up.
Greatly reduced variability.
Burst suppression
EEG is synchronised with the aEEG recording
and is displayed onscreen.
SHUT DOWN
When monitoring is no longer required:
Press “Quit” button on screen to stop recording and return to the master menu.
QUIT
Files can be archived to USB Stick or to CD. Select “Flash Stick” or Archive from
the master menu to save the data.
Pattern of high amplitude EEG activity interrupted by relatively low amplitude activity.
Quit the master menu and shut down the computer through windows.
Turn off the Unique CFM amplifier using the on/off switch.
Remove electrodes from headbox.
Unique CFM can now be removed from the clinical area.
Amplifier and headbox can be wiped down with alcohol wipes as appropriate.
Needles and Hydrogel electrodes should be removed carefully from the patient
and disposed of appropriately.
Spectral Arrays (DSA/CSA) can be displayed onscreen this is also
synchronised with the aEEG and EEG.
This is a function of Frequency rather than amplitude and can
give further diagnosis and interpretation of artefact.
Cool Colours indicate less dominant frequencies.
Warm Colours indicate more dominant frequencies.
ELECTRODE PLACEMENT
Number of electrodes will vary from 3 – 5, dependant on the headbox chosen and
aEEG channels to be displayed.
3 Electrodes for Single Channel recording
P3
P4
P3
P4
Ground (Black) electrode placed in midline in front of the fontanel. Reference (Red) and
Active (Yellow) electrodes placed bi-parietal, 75mm apart evenly spaced from midline P3/P4.
4 Electrodes for Dual Channel & Unipolar recording
P3
P4
Ground (Black) electrode placed in midline in front of the fontanel
(or shoulder). Reference (Red) electrode should be placed in
midline in front of the fontanel. Active (Yellow) electrodes placed
bi-parietal, 75mm apart evenly spaced from midline P3/P4.
5 Electrodes for Dual Channel & Unipolar recording
C3
P3
C4
P4
Ground (Black) electrode placed in midline front of the fontanel
(or shoulder) Reference (Red) electrodes placed bi-parietal,
75mm apart evenly spaced from midline C3/C4. Active (Yellow)
bi-parietal, 75mm apart evenly spaced from midline P3/P4.
Note: In all positions if hair or Oedema does not allow for bi-parietal placement, bi-temporal placement can
be used. If needle electrodes are to be used, they should be placed superficially and secured with tape.
If hydrogel electrodes are to be used, the skin should be clean, dry and prepared with Nu-Prep to remove
dead skin etc.
ECG Placement
ECG can be measured using the dual channel style headboxes. Place
Active (Yellow) and Reference (Red) electrodes in the appropriate position.
Ground electrode is already sited for aEEG.
