1. A system for confirming a tip location of a catheter previously placed within a patient, the system comprising:
an ivECG acquisition module;
a multiscale complexity analysis module;
a notification module, including one or more features selected from an audio feature, a video feature, and a tactile feature; and
an adaptor configured to couple to the catheter previously placed within the patient, the adaptor configured to establish an electrical pathway with the ivECG acquisition module via a saline column or an electrically conductive device,
wherein the multiscale complexity analysis module uses ivECG signals, provided by the ivECG acquisition module and the electrical pathway, to provide a PxI (proximity index), the notification module indicating a location of a distal tip of the catheter relative to a predetermined target location.
