Understanding Impedance Values

Impedance values are important indicators when
delivering test stimulation or stimulating with the
Stimulator. The impedance values provided by the CP are
icons representing the quality of the circuit being used to
deliver stimulation.
Impedance can be tested when a
present. When the button is pressed, the CP will display
either:
A single impedance icon corresponding to the
•
connection for foramen needle stimulation.
4 impedance icons, each corresponding to the
•
connection for one of the electrodes on the tined
lead.
The impedance icon can have one of 4 states:

Note: See the manual sections on Troubleshooting for steps to
resolve out of range ("Bad") impedance values.
1 Good
The impedance level indicates a
•
good connection and is preferred for
stimulation.
2 OK
The impedance level indicates an
•
acceptable connection and is allowed
for stimulation.
3 Bad – Open
The impedance level indicates an open
•
circuit and stimulation is not possible.
4 Bad – Short
The impedance level indicates a
•
short circuit and stimulation is not
recommended.
