Problems solved by technology

This results in batteries that are excessive in both size and weight, which limits their portability and convenience, and, in the case of externally wearable defibrillators such as LifeVest (ZOLL Medical, Chelmsford, MA), Limits their wearability and comfort
Additionally, the battery remains the least reliable component of currently manufactured AEDs, with periodic recalls due to manufacturing defects and the normal end-of-life degradation that always comes with batteries, but batteries are particularly troublesome for life-saving devices

Embodiment Construction

[0034] This specification discusses systems and techniques for delivering defibrillation energy in a controlled manner. Typically, such energy needs to be built up, for example by charging a capacitor, and this energy buildup can take a considerable time. Using the techniques described herein, the system can pre-analyze the patient's need to deliver a defibrillation pulse (e.g., while the rescuer is performing chest compressions), and can place a capacitor or other appropriate The energy delivery mechanism is charged so that the shock can be delivered on demand.

[0035] Referring now to FIG. 2, there is shown an AED 10 that may be used to deliver a defibrillation shock at the appropriate time. In this figure showing an example implementation, a rescuer uses AED 10 to automatically monitor a patient during cardiac resuscitation. The AED 10 uses the measured ECG signal to monitor the patient's heart and recharge the defibrillation device within the AED while resuscitating the...

Abstract

A system and method relate to the field of cardiac resuscitation and, in particular, to an apparatus for assisting a rescuer in performing cardiopulmonary resuscitation (CPR).

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 61 / 304,119, filed Feb. 12, 2010, entitled "DEIBRILLATOR CHARGING," and U.S. Provisional Application No. 61 / 304,119, filed Feb. 24, 2010, entitled "DEIBRILLATOR DISPLAY." Priority to U.S. Provisional Application No. 61 / 307,690, each of which is hereby incorporated by reference in its entirety. technical field [0003] This document relates to cardiac resuscitation, and in particular to systems and techniques for assisting rescuers in performing cardiopulmonary resuscitation (CPR). Background technique [0004] The heart relies on an orderly sequence of electrical impulses to beat efficiently. Deviations from this normal sequence are known as "arrhythmias". Some medical devices include signal processing software that analyzes electrocardiogram (ECG) signals acquired from treated patients (e.g., patients in emergency situations) to determine when conditions such a...
