Electrode delivery system

An automatic external defibrillator configured to deliver electrical pulses and/or shocks to a heart of a patient during a cardiac emergency, the defibrillator comprising:

• a housing supporting an electrical connector, a battery and high voltage circuitry;
• and
• a pair of contact pads supported in a surface of the housing;
• a pair of defibrillation electrode pads supported on the housing, wherein each of the pair of defibrillation electrode pads is pre-connected to the electrical connector of the housing, and wherein each defibrillation electrode pad is in electrical communication with the battery and the high voltage circuitry;
• wherein the defibrillator is automatically activated by a separation of at least one of the pair of defibrillation electrode pads from the housing;
• and
• wherein a hydrogel layer of each defibrillation electrode pad is retained by the housing in such a manner so as to reduce a moisture vapor transmission rate thereof,
• wherein each contact pad is electrically connected to the connector of the housing by a respective electrical connector, and wherein each electrode pad of the pair of defibrillation electrode pads is disposed on a surface of the housing so as to be in contact with a respective contact pad.
