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:
button is
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 .
