A device, system and method for measuring the impedance during a medical procedure being performed on a patient is disclosed. The device, system and method include an electrode capable of being used in the medical procedure, a plurality of patches operationally located on the surface of a body of the patient, and a sensor for measuring a signal between the electrode and at least one of the plurality of patches, the signal being processed using a processor using a first filter and a second filter, and combining the result of the first filter and the second filter using a weighting of the filters to provide a measurement of the impedance, wherein the impedance indicates the end of the medical procedure.
