3 Skin Preparation and Sensor Positioning
To ensure low sensor impedance, clean skin with mild soap and water is recommended as a skin
cleanser.
The CSM Procedure Pack contains a skin preparation product and 3 neuro sensors.
Dry-abrade the skin gently using the skin prep product or with a dry wash cloth or gauze, to remove
the non-conductive skin layer. See diagram below.
Position of the three sensors from your CSM Procedure Pack according the diagram below
Shown above is a left sided setup; right sided is also acceptable. Place sensors at the side farthest
from the surgical area.
The advanced signal processing of the monitor ensures that a deviation in the positioning of the
sensors up to 2 cm (0.78 in) has no significant influence on the index. However, it is recommended
to place the sensors on an area of the skull where only a few muscle fibers are present in order to
achieve the best quality signal.
Middle of forehead
Left side of forehead
Mastoid left side
Note: Alcohol is not recommended as a skin cleanser; it leaves a film layer that may cause
high sensor impedance. If alcohol is used, ensure 30 second dry time.
Caution:
-
Make sure no part of the sensors is in contact with any other conductive parts including
earth/ground.
-
If skin rash or other unusual symptoms develop, remove sensors from patient.
-
Change sensors every 24 hours to check skin integrity.
Note: Once the sensors have been secured on the skin, attach the color-coded wires on the
patient cable to appropriate sensor.
Note: The performance of the CSM is only guaranteed by the manufacturer when the CSM
Procedure Pack is used.
