•
Channel 1 (1a
1b) is generally positioned on the healthy side;
the evaluation always refers to channel 1.
Channel 2 (2a
2b) is positioned on the side to be operated, or sick side.
1. Wipe the skin at the electrode positions with alcohol or an alcohol pad.
2. Apply a drop of preparation cream (0.5 – 1 ml) to a gauze swab. Use the swab
to treat the skin at the electrode positions carefully and thoroughly.
3. Rub the skin dry with a dry gauze swab.
4. Pull off the protective material from the electrode and then stick the electrode on
the skin. Avoid exerting pressure on the center of the electrode since this could
cause the electrode gel to be pressed under the adhesive ring, thus reduces the
electrode adhesion.
5. Connect the pushbutton adapters of the patient lead to the electrodes.
6. Seal the pouch with unused electrodes as airtight as possible.
•
Spacing: at least 8 cm (3 in) between
1a and 1b (1-channel recording)
1a/2a and 1b, 1a/2a and 2b (2-channel recording)
•
Electrode impedances: < 2 k
Ω
(max. 8 k
Ω
)
Ensure uniform impedance values to the extent possible.
* The Reference electrode (R)
can be placed anywhere in the
forehead area.
