Olympic CFM 6000 Data Displays
The Olympic CFM 6000 records and displays three types of tracings: CFM, EEG, and
impedance.
CFM Tracings
The CFM tracing indicates the overall electrocortical background activity of the brain by
recording amplitude-integrated electroencephalography (aEEG). The EEG signal is
filtered, rectified, and semi-logarithmically compressed. It is then displayed at a very slow
chart speed, 1 mm per minute. A high reading on the chart indicates a high level of activity;
a low value indicates low activity. The CFM 6000 screen shows three hours of a CFM
tracing.
The CFM 6000 may be applied at any time, or used continuously, to determine the
neurological status of a patient. A minimum of 20 minutes of trace should be observed to
make a determination of neurological status. However, when there is a question about the
presence of seizures, or potential changes in neurological status as a result of illness or
other clinical treatment, it is generally best to observe the record for a longer, continuous
period. The exact length of this period depends on the frequency of the seizures, or the
condition or treatment being monitored. The CFM may record continuously for up to 30
days.
A CFM tracing is created by the continuous up and down movement of a digital pen
responding to subtle variations in a brain's electrocortical activity. A tracing rises in
response to increased activity and drops in response to lowered activity according to a
fixed algorithm. With the pen moving at a very slow rate across the screen, 1 pixel width
of CFM tracing reflects about 15 seconds of data.
Previous versions of the Olympic CFM 6000 offered only one view, CFM Basic. The CFM
Basic view shows a series of vertical lines of different lengths, each of uniform density.
This view shows no variation in the color of the 'ink.' CFM 6000 version 2.0 introduces a
new and more sensitive view, CFM Insight. This view shows each vertical line with
variable density that reflects the relative amount of time the brain spends at different levels
of electrical activity, more closely approximating the trace generated by a CFM 5330
(Lectromed). Sometimes these two views are nearly identical; in other cases, Insight
provides a clear gray-scale effect where a dark central band of activity can be seen,
surrounded by lighter bands of activity above or below. This can be a valuable aid to
identification of artifacts and can help identify certain conditions more clearly. The
CFM 6000 now offers both views and the capability to toggle between them. The
following illustration shows a tracing with both views.

OLYMPIC CFM 6000 Operator’s Manual 9
Figure 3 Basic and Insight views
EEG Tracings
The EEG tracing shows the underlying EEG detail that relates to the cursor position on the
CFM tracing. The EEG cursor on the CFM tracing represents 15 seconds. The EEG
window shows between 3 and 14 seconds of the EEG tracing at a time, depending on the
EEG speed setting. The EEG can help confirm seizures and other brain activity. Display
the EEG at a lower amplitude setting to see more detail; display it at a higher amplitude
setting to show only major events. For information about changing speed and amplitude
settings, see Changing EEG Speed and Amplitude on page 20.
The following illustration shows a CFM tracing with underlying EEG data.
Figure 4 CFM tracing with EEG detail
Impedance Tracings
The impedance tracing indicates the connection quality (contact between the patient and
the electrodes) and distinguishes noise. Impedance greater than 20 kΩindicates that the
electrodes should be reapplied or replaced. Occasional random spikes might occur when
electrode conductivity changes for brief moments. The Lead-Off alert appears and sounds
if the impedance becomes greater than 20 kΩfor more than three seconds.
Tip: To maintain good impedance when recording over long periods of time, it might be
necessary to reattach or replace the electrodes periodically.
The following illustration shows a CFM tracing with the associated impedance tracing.

Read the warnings and cautions on page 2 before operating this device.
To obtain assistance or reorder items, see Service on page 34 and Replacement Parts on
page 34.

OLYMPIC CFM 6000 Operator’s Manual 11
Adhesive tape, Coban™wrap, or Kling®wrap (if using low-impedance needle
electrodes)
1Verify that the amplifier module is connected to the CFM 6000 and that the
CFM 6000 is turned on.
2Determine whether to place electrodes biparietally or frontally and whether to use
hydrogel or low-impedance electrodes, and then locate the areas of contact on the
patient’s head according to one of the following placement methods:
Placement method 1 — Biparietal placement for hydrogel or low-impedance
needle electrodes:
Figure 6 Biparietal placement
aLocate the vertex and identify a point 25 mm anterior to it. The BLACK
electrode (1) is to be placed at this location.
bLocate a point approximately 50 mm posterior to the vertex. The RED electrode
(2) is to be placed approximately 37 mm to the patient’s left of this point (right
if facing the patient).
cThe YELLOW electrode (3) is to be placed approximately 75 mm to the
patient’s right of the red electrode (left if facing the patient).
CAUTION
Medications may affect the patient’s record. Anticonvulsants or sedatives may transiently
suppress the CFM record. Administration of drugs or other clinical events should be noted
to facilitate interpretation of the record.
Poor electrode contact may cause high impedance. To ensure good electrode contact,
always prepare the patient’s skin before attaching the electrodes.
NOTICE!
For instructions and warnings relating to cleaning agents and skin prep gel (for example,
alcohol wipes or NuPrep), consult the product instructions.
NOTE
#
Depending on the type of electrodes used, color coding indicated below may not be applicable.
The BLACK electrode is the ground; the YELLOW electrode is placed on the patient’s right (left
when facing the patient); and the RED electrode is placed on the patient’s left (right when facing
the patient).

12 OLYMPIC CFM 6000 Operator’s Manual
Placement method 2 — Frontal placement for hydrogel electrodes (use this
method if hair interferes with biparietal placement of hydrogel electrodes):
Figure 7 Frontal placement
aThe BLACK electrode (1) is to be placed at the center of the patient’s forehead
as close to the hairline as possible.
bThe YELLOW electrode (2) is to be placed approximately 37 mm to the
patient’s right of the center electrode (left if facing the patient).
cThe RED electrode (3) is to be placed approximately 37 mm to the patient’s left
of the center electrode (right if facing the patient).
3Visually examine the electrode package for damage before opening it. Remove the
electrode set from the package, and examine the electrodes and leads. If damage is
apparent, discard the set.
4Clean and dry the areas of the patient’s head where the electrodes are to be placed.
Do not use alcohol for cleaning: alcohol can increase impedance.
5If using hydrogel electrodes, prepare the areas of contact prior to placement, as
follows:
aApply a small dot of skin prep gel, such as NuPrep, to each area of contact. You
can use a 2x2 or 4x4 gauze pad to apply the NuPrep.
bVigorously rub the NuPrep over the skin for 20 to 30 seconds, removing the
surface layer of dead skin to improve conductivity. Ensure that the entire surface
area to be covered by the electrode is prepared.
cThoroughly remove the NuPrep with a new, clean gauze pad, and make sure the
area is completely dry.
6After the area is prepared, attach the electrodes, as follows:
For low-impedance electrodes, insert the needle subcutaneously up to the plastic
hub and secure as you would an IV.
For hydrogel electrodes, run a finger around the edges of the electrode for 20 to
30 seconds to ensure a secure seal.
NOTE
#
It is recommended that you prep and place one electrode at a time when possible.
NOTE
#
Where hair might present a barrier to good electrode contact, either shave the area or tamp
down the hair with water during cleaning, and then pat dry.
NOTE
#
Always apply the skin prep gel directly to the skin. Never apply it directly to an electrode
because it can increase impedance.

OLYMPIC CFM 6000 Operator’s Manual 13
7Form a strain relief to minimize motion artifact by collecting the three leads into a
bundle and tying the bundle into a small, loose loop near the electrodes. The strain
relief loop should be as close to the electrodes as possible, while remaining isolated
from them. Secure the loop to the patient’s head with Coban™or Kling®wrap. If
desired, create a second strain relief loop near the amplifier end of the leads.
8Connect the leads to the amplifier module, matching them to the corresponding
color-coded receptacles, and clip the amplifier module to the patient’s bedding.

Alerts
Alerts are status messages that appear in color-coded boxes at the top of the CFM 6000
screen: green for normal, yellow for caution, red for stop and take action. For red alerts, a
dialog box describes the action that is needed. For these alerts, take the appropriate action
and press OK to close the dialog box, stop the alarm, and resume recording.
The possible alerts are the following:
Alert Meaning

occurs each time recording is started. It is important to wait for
calibration to complete before attempting any other tasks.
CALIBRATION The calibration check failed. The amplifier module needs to be
replaced.
CHECK SUM The amplifier non-volatile RAM is corrupted. The amplifier module
needs to be replaced.
COMM ERROR A communication error occurred between the amplifier module
and the CFM 6000. Disconnect and reconnect the amplifier module.
Replace the module if the problem is not corrected.
