Diagnostic/Parameter Result Summary
Lead Impedance
Description: Indicates measured or estimated impedance when delivering the
output current during testing and whether it's within normal range.
Values/Results: Measured lead impedance value (ohms) and overall status of
OK, LOW, or HIGH
What Does the Value or Result Mean?:
OK: Impedance is within acceptable operating range.
No special attention is required.
LOW: Impedance is lower than expected and it may be indicative of a short
circuit condition or a defective generator.
See "Troubleshooting" for additional instructions.
HIGH: Impedance is higher than expected and the generator may not be able
to deliver the programmed therapy. See "Troubleshooting" for additional
instructions.
Generator Battery
Description: Indicates battery status of the generator using
one of the following:
• OK
• Intensified Follow-up Indicator (IFI)
• Near End of Service (N EOS)
• End of Service (EOS)
Values/Results: OK, IFI, N EOS, EOS
What Does the Value or Result Mean?:
OK:
Battery level is within normal operating range and no special attention
is required.
IFI:
The battery has depleted to a level where more frequent clinical
monitoring is recommended.
N EOS: The Generator should be replaced as soon as possible.
EOS:
The generator is no longer supplying stimulation and immediate
replacement is recommended. If the generator is not replaced, it will
eventually lose the ability to communicate with the software.
Output Current/Current Delivered
Description: Indicates the stimulation output current delivered during the
Diagnostics test, and the test status based on the programmed settings
Values/Results: Output current value (mA) and overall status of OK or LOW
What Does the Value or Result Mean?:
Value indicates the stimulation output delivered during the diagnostic test.
OK: Current is being delivered at the programmed level.
LOW: Programmed current is possibly not being delivered at the specified level.
