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
a low value indicates low activity. The CFM

The CFM 6000 may be applied at any time, or used continuously, to determine the
neurological status of a patient. A minimum of 20
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
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.

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
The following illustration shows a CFM tracing with underlying EEG data.

Changing EEG Speed and Amplitude on page 20.
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
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
kΩ for 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.

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.
For instructions and warnings relating to cleaning agents and skin prep gel (for example,
alcohol wipes or NuPrep), consult the product instructions.
1 Verify that the amplifier module is connected to the CFM 6000 and that the
CFM 6000 is turned on.
2 Determine 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:
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).
Placement method 1 — Biparietal placement for hydrogel or low-impedance
needle electrodes:
Figure 6
Biparietal placement
a Locate the vertex and identify a point 25 mm anterior to it. The BLACK
electrode (1) is to be placed at this location.
b Locate 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).
c The YELLOW electrode (3) is to be placed approximately 75 mm to the
patient’s right of the red electrode (left if facing the patient).

as close to the hairline as possible.
b The YELLOW electrode (2) is to be placed approximately 37 mm to the
patient’s right of the center electrode (left if facing the patient).
c The RED electrode (3) is to be placed approximately 37 mm to the patient’s left
of the center electrode (right if facing the patient).
3 Visually 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.
4 Clean 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.
It is recommended that you prep and place one electrode at a time when possible.
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.
5 If using hydrogel electrodes, prepare the areas of contact prior to placement, as
follows:
a Apply 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.
Always apply the skin prep gel directly to the skin. Never apply it directly to an electrode
because it can increase impedance.
b Vigorously 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.
c Thoroughly remove the NuPrep with a new, clean gauze pad, and make sure the
area is completely dry.
6 After 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.

Managing Files
The hard disk in the CFM 6000 can store approximately 20,000 hours of data. If the hard
disk is full, an error occurs when you attempt to save another session. In this case, you can
archive sessions to CD and delete them from the hard disk to free up disk space. To
periodically check the percentage of free space on the hard disk, see
Space on page 28.
Although your facility can define standards as to when to archive sessions for inclusion in
patient records, it is recommended that you archive each session as you complete recording
it.
If you want to view sessions that are archived on a CD, you can restore them to the

Disposing of Product
The CFM 6000 and the CFM cart do not have any components that require special disposal
precautions, except as stated for electrodes. Thus, product disposal should be handled
according to national laws and regulations.
The fluorescent lamp in the LCD display contains a small amount of Mercury. Follow
local ordinances and regulations for disposal.
Assembling the CFM Cart
Required items:
Cart base with foot pedal, screws, and Allen wrenches (5/32 in. and 3/16 in.)
Cart post with handle and drawer assembly
To assemble the CFM cart:
1 Remove the cart components from the shipping boxes.
2 Place the cart post upside-down, with the drawer resting on the floor.
If the post is not at a 90º angle to the drawer, the tilt adjustment may require tightening.
Use the small Allen wrench to tighten the screws on the tilt adjustment hinge, which is
located on the underside of the drawer.
3 Place the cart base, wheels facing up, onto the post. Align the key on the base with
the key slot on the stand (see Figure 12).
Figure 12
Placing the cart base onto the post
4 Place the foot pedal on the handle-side of the base. Ensure that the foot pedal label
is facing the drawer, and then use the larger Allen wrench to securely tighten the
two screws (see Figure 13).

Removing the drawer
2 Remove the tape securing the thumbscrews, and ensure that the thumbscrew spacers
are not resting on the threads. The spacers should spin freely.
If the thumbscrew spacers rest on the threads, they act as a jam nut, preventing secure
placement of the CFM 6000 on the cart.
3 Place the CFM 6000 on the top of the drawer enclosure, visually aligning the device
to the thumbscrews (see Figure 15). The thumbscrew heads are located inside the
drawer cavity. To maintain balance, tighten the thumbscrews incrementally in a
circular or X-pattern.

First, place the CFM 6000 on the
top of the drawer enclosure,
visually aligning the device to the
thumbscrews.
Next, incrementally tighten
the thumbscrews in a
circular or X-pattern.
With the slides fully extended, place
the drawer down onto the slides.
Each slide locks in position in three
locations and an audible click

a Plug the power cord into the power receptacle on the back of the CFM 6000.
b Unscrew the thumbscrew on the back of the drawer on the CFM cart (see
Installing the drawer
Figure 17). Select a cord clamp — small diameter for a European power cord, or
larger diameter for a North American power cord.
c Place the appropriate cord clamp on your power cord, and then tighten the
thumbscrew.
d Wrap any excess power cord around the cord cleats on the back of the drawer
(see Figure 17).

Securing the power cord to the CFM Cart
To check the function of the CFM cart:
1 Confirm that the height of the cart can be adjusted. While stepping on the foot
pedal, pull the handle up, and then push it down to ensure that the pole raises and
lowers (see Figure 2 on page 7).
2 Ensure that the tilt adjustment is firm. Place one hand on top of the CFM 6000 and
the other on the bottom of the drawer, and then firmly tilt the drawer forward and
backward (see Figure 2 on page 7).
3 Ensure that the drawer opens and closes with ease, and that it latches when in the
closed position.
4 Confirm that the two locking caster wheels lock and unlock (see Figure 1 on
page 7).
