Why does the magnetic navigation stylet icon have erratic behavior on my Bard Sherlock 3CG Tip Confirmation System?

If the magnetic navigation stylet icon on your Bard Medical Equipment exhibits erratic behavior, it could be due to the stylet being at the edge of the sensor's depth range (3 to 11 cm) or magnetic interference. Try pulling the catheter back until the stylet icon is stable, verify the catheter is moving in the correct direction, and continue placement. If magnetic interference is the issue, pull the catheter tip back at least 12 inches (30 cm) from the sensor, recalibrate, and re-advance the catheter. It might also be that too much time has passed since calibration, so recalibrating might help.
