1. A defibrillator comprising:
- an impedance measure module configured to measure an impedance between a first test lead and a second test lead in electrical contact with a hydrogel bridge, the first test lead and the second test lead being a separate structure from, and being electrically isolated from, a therapy delivery plate of a defibrillation electrode capable of delivering electrical therapy when coupled to the defibrillator; and
a processor configured to determine whether the defibrillation electrode is in a condition for replacement as a function of the measurement.

Abstract
The invention presents an apparatus and techniques for determining whether a medical electrode, such as a defibrillation electrode coupled to an automated external defibrillator, is in a condition for replacement. The determination can be made as a function of one or more data. In one exemplary embodiment, the determination is a function of one or more measurements of an impedance of a hydrogel bridge in a test module. In another exemplary embodiment, the determination is a function of one or more environmental condition data from one or more environmental sensors.
