Abstract
Abstract An automated external defibrillator which automatically performs self-tests on a daily and weekly basis. Tested functions include the presence and interconnection of defibrillator electrodes, battery charge state and the operability of the high voltage circuit. Visual and audible indicators are actuated to alert an operator if faults are identified. A record of each self-test is stored in memory, and can be subsequently retrieved through a communications port.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
139 words
A one button method of applying a defibrillation shock to a patient using an automated external defibrillator (AED) having a case including an electrode compartment, a pair of electrodes stored within the electrode compartment, an openable lid covering the electrode compartment, a high voltage circuit, and an operator-actuated rescue switch, the method including the steps of: opening the lid covering the electrode compartment to expose the electrodes therein wherein the electrodes are electrically connected to the AED prior to the opening of the lid and wherein the step of opening the lid causes the AED to be powered ON; retrieving the electrodes stored in the compartment; applying the electrodes to the patient; pausing while the high voltage circuit charges; and actuating the operator-actuating rescue switch a single time to apply a defibrillation shock to the patient via the electrodes.
Claim 2
Dependent Claim
