1. An automatic external defibrillator, which comprises:
- a defibrillator housing including circuitry adapted to deliver electrical signals to a heart of a subject during a cardiac emergency, the defibrillator housing having at least one electrode support surface associated therewith; and
a pair of defibrillation electrode pads in electrical communication with the circuitry of the defibrillator housing, the electrode pads each having a conductive hydrogel layer, and being mounted to the at least one electrode support surface of the defibrillator housing when in a stored condition thereof with the hydrogel layer in releasable secured contacting relation with the at least one electrode support surface, whereby moisture loss of the hydrogel layer is substantially minimized when the electrode pads are in the stored condition to thereby sustain operability of the electrode pads until when the electrode pads are detached from the electrode support surface to assume an operable condition for application to the subject.

Abstract
An automatic external defibrillator configured to deliver electrical pulses and/or shocks to a heart of a patient during a cardiac emergency includes a housing supporting an electrical connector; a defibrillator electrode delivery system supported on the housing and a pair of defibrillation electrode pads supported by the defibrillator electrode delivery system. Each of the pair of defibrillation electrode pads is pre-connected to the electrical connector of the housing. A hydrogel layer of each defibrillation electrode pad is retained by the defibrillator electrode delivery system in such a manner so as to reduce a moisture vapor transmission rate thereof.
