electrodes)
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
CAUTION 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,
NOTICE!
alcohol wipes or NuPrep), consult the product instructions.
Verify that the amplifier module is connected to the CFM 6000 and that the

CFM 6000 is turned on.
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:

Biparietal placement
Locate the vertex and identify a point 25 mm anterior to it. The BLACK
a
electrode (1) is to be placed at this location.
Locate a point approximately 50 mm posterior to the vertex. The RED electrode
b
(2) is to be placed approximately 37 mm to the patient's left of this point (right
if facing the patient).
The YELLOW electrode (3) is to be placed approximately 75 mm to the
