Problems solved by technology

Also, while CPR precordial compressions are performed at the rescue scene to improve the chances of resuscitation, the long pauses between discontinuous CPR and shock delivery performed on patients suffering from ventricular fibrillation will significantly reduce the chances of resuscitation

Embodiment Construction

[0020] In order to facilitate understanding of the present invention, a conventional method of providing resuscitation of a victim will be described.

[0021] During the resuscitation of a victim of sudden cardiac arrest, rescuers are often programmed to apply a defibrillating shock from an automated electronic defibrillator (AED) and deliver intervals of cardiopulmonary resuscitation (CPR) to stimulate circulation until Re-establish the normal cycle. In many cases, the resuscitation protocol guides the rescuer through the AED using voice prompts. For example, a victim of asystole due to ventricular fibrillation may receive several defibrillation shocks after a predetermined interval of CPR in which the rescuer provides precardiac compressions and breathing assistance to the victim.

[0022] Those of ordinary skill in the art will appreciate that precardiac compression during CPR is believed to provide artificial circulation, which improves the victim's chances of survival. ...

Abstract

A defibrillator (6) having a pair of electrodes (8) for delivering an artifact-compensated defibrillation shock and a method thereof is provided. Electrocardiographic (ECG) data representative of an ECG signal is acquired for the patient and the ECG data is analyzed to determine whether administration of a defibrillating shock is appropriate. A cardiopulmonary resuscitation (CPR) interval is initiated subsequent to the acquisition of ECG data. Upon completion of the CPR interval, and if administration of a defibrillating shock is determined to be appropriate from the ECG data, arming the AED (6) for delivery of the defibrillation shock to the patient.

Description

technical field [0001] The present invention relates to apparatus for electrical therapy, and more particularly to a defibrillator for rapidly delivering defibrillation pulses with minimal delay following intervals of cardiopulmonary resuscitation (CPR) on a patient. Background technique [0002] Medical device manufacturers have developed automated electronic defibrillators (AEDs) to provide early defibrillation. AEDs deliver high-amplitude current pulses, waveforms, or shocks to the heart to restore the patient's heart rhythm to normal levels. For example, FIG. 1 depicts a conventional AED 6 being administered to a cardiac arrest victim 2 by a rescuer 4 . As shown in FIG. 1 , a pair of defibrillation electrodes 8 are placed in an anterior-anterior (AA) position on the victim's torso for delivering a shock. Cardiopulmonary resuscitation (CPR) often must be performed on the patient at times during a defibrillation shock in order to resuscitate the victim from cardiac arres...
