Actions to take:
1. Under fluoroscopic or echocardiographic guidance, determine the catheter position.
2.
Reduce P-level to P-2 and reposition the catheter by either pushing the catheter
forward or pulling it back as needed. Confirm that the placement signal and motor
current are both pulsatile.
3.
If fluoroscopic or echocardiographic imaging is not available, obtain imaging equipment
(fluoroscopy, echocardiography, or chest x-ray) to check the catheter position.
