Placing the electrodes for ABR testing
Skin preparation
Note: Do not use alcohol pads or other cleaning agents that contain alcohol to prepare the skin as they may cause the skin to dry
out, leading to a higher skin impedance.
1.
Place the electrodes on the patient as follows:
Red
On the nape of the neck
Black
On the cheekbone (common or ground electrode)
White On the upper part of the forehead
2.
Make sure that the electrodes fit tightly on the skin.
Warning: The hydrogel of the electrodes can dry out. Make sure that used packages are closed properly.
Dried out hydrogel may cause unexpectedly high electrode impedance. Change the electrodes if you suspect that the
electrode hydrogel is dry.
Note: The black electrode (common or ground electrode) could alternatively be placed on the baby's chest or shoulder. The red
and white electrodes must, however, be placed as stated, e.g., on the nape of the neck and on the upper part of the forehead,
respectively. Other electrode placements have not been validated.
