6.3 Magnetic Navigation Troubleshooting
Magnetic navigation does not detect
stylet.
Note: Depth icons will not be present.
Cause: Sensor incorrectly oriented.
Solution: Orient sensor correctly per procedure.
Cause: Stylet outside sensor depth range (3 to 11 cm).
Solution: - If the vein is deep, ensure that the top of the sensor on the insertion side is
touching the patient's skin (e.g. by using tape).
- If the vein is shallow, lift the sensor away from the skin (e.g., by using a folded blanket).
Cause: Too much time has passed since calibration. Magnetic fields have changed.
Solution: Pull catheter tip back at least 12 inches (30 cm) from the sensor, recalibrate and
re-advance catheter.
Cause: Stylet did not advance under the sensor.
Solution: Pull catheter back and re-advance.
Cause: Stylet not at the catheter tip.
Solution: Ensure stylet tip is within 1 cm of distal end of catheter. Adjust as necessary.
Cause: Incompatible catheter.
Solution: Verify that the Bard Access Systems’ catheter kit has a [ ] icon or [ ] icon.
Cause: Stylet magnet trimmed off.
Solution: Replace catheter with a new Bard Access Systems’ catheter from a kit labeled
[ ] or [ ].
Cause: Stylet is out of sensor's depth range (3 to 11 cm)
Solution: 1. Pull catheter back until stylet icon is stable.
2. Verify catheter is moving in the correct direction and continue placement using
ECG guidance and catheter measurement.
Cause: Magnetic interference.
Solution: Pull catheter tip back at least 12 inches (30 cm) from the sensor, recalibrate and
re-advance catheter.
Magnetic navigation Stylet icon has
erratic behavior.
Cause: Stylet at edge of sensor’s depth range (3 to 11 cm).
Solution: 1. Pull catheter back until stylet icon is stable.
2. Verify catheter is moving in the correct direction and continue placement.
Cause: Magnetic interference.
Solution: Pull catheter tip back at least 12 inches (30 cm) from the sensor, recalibrate, and
re-advance catheter.
Cause:
Too much time has passed since calibration. Magnetic fields have changed.
Solution: Pull catheter tip back at least 12 inches (30 cm) from the sensor, recalibrate and
re-advance catheter.
Magnetic navigation Stylet icon
disappears, "sweeping magnifying glass"
displayed.
Cause: Stylet is out of sensor’s depth range (3 to 11 cm).
Solution: 1. Pull catheter back until stylet icon is stable.
2. Verify catheter is moving in the correct direction and continue placement using
ECG guidance and catheter measurement.
Cause: Magnetic interference.
Solution: Pull catheter tip back at least 12 inches (30 cm) from the sensor, recalibrate, and
re-advance catheter.
Cause:
Too much time has passed since calibration. Magnetic fields have changed.
Solution: Pull catheter tip back at least 12 inches (30 cm) from the sensor, recalibrate and
re-advance catheter.
