Abstract
Abstract A disposable electrode pad is provided for a defibrillator electrode. The pad is saturated with electrically conductive greasy material, sometimes known as electrogel. The pad is designed for adhesive or other securing to the electrode, and the pad is covered with a tear-off aluminum sheet cover to protect the integrity and sanitation of the pad, while still allowing sufficient electrical conductivity for monitoring a patient's heartbeat through the electrode.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
123 words
The method of using a monitoring and defibrillating electrode having a disposable electrode pad thereon impregnated with an electrically conductive gel and covered with a conductive metallic foil which comprises pressing said foil against the skin of a patient's chest, monitoring the heartbeat of such patient through the electrode and the foil, and, in the event of detecting fibrillating of the heart of said patient, at least partially removing said foil and directly contacting the skin of said patient's chest with said electrode pad containing the electrically conductive gel, applying a defibrillating electrical charge to the heart of said patient through the electrode and the electrically conductive gel, and thereafter discarding said disposable electrode pad and substituting a new one on said electrode.
