Additional information related to stimulation
Source Voltage
The source voltage for the current stimulators is approx. 400 V. If the load impedance exceeds
400 V/I
skin
, where I
skin
denotes the selected stimulating current, the stimulators will be unable to
provide the selected currents. Furthermore, the stimulators will be unable to provide more
than approx. 0.5 W. This may limit the output current for fast stimulations.
Stimulation Electrodes
Recommended Stimulation Electrodes
The recommended stimulation electrodes to be used in ordinary investigations are:
Electrode Number Type
9013S030 Digital Ring Electrode
9013L069 Velcro Digital Ring Electrode
9013L036 Hand-held Stimulation Electrode
9031E017 Advanced Stimulation Handgrip
When using the surface (cutaneous) electrodes, the following applies:
Before applying the 9013L036 felt tips, or any of the 9013S070-series of ground electrodes to
a patient, they should be soaked in saline to obtain good electrical contact with the skin. Each
pair of felt tips is for use with one patient only.
Similarly, when using the electrode pins of the 9031E017, or other electrodes with metal
contact provided without a conductive gel, skin impedance can be reduced using electrode
paste or an equivalent.
When using the reusable surface electrodes, make sure to reprocess them in accordance with
the manufacturer’s instructions and in accordance with a validated infection control
procedure.
