An improved emergency response system includes a set of databases which relates to volunteer responders and patients, which is controlled by a central system computer. The system interacts with patients and volunteer responders through a wireless network to patient and volunteer communicator devices. The emergency response system calculates and provides a compensation to the volunteer responders based upon their on-duty time, proximity to enrolled patients, and optionally based upon their performance during training and cardiac rescue events.

Rapid response system for cardiac arrest

An apparatus and method provides improved guidance instructions to providers of cardiopulmonary resuscitation (CPR) compressions in a cardiac arrest event. The apparatus detects CPR rate and/or changes in CPR rate, and issues prompts related to checking the depth of compressions based upon the rate/rate change detection. The prompts may be aural or visual.

Smart prompting to improve responders CPR performance

A defibrillator and method for using a defibrillator which adopts an ECG analysis algorithm that can detect a cardiac arrhythmia in the presence of noise artifact induced by cardio pulmonary resuscitation (CPR) compressions. The apparatus and method offers guidance throughout a cardiac rescue protocol involving both defibrillation shocks and CPR that improves the effectiveness of the rescue, resulting in more CPR 'hands-on' time, better treatment of refibrillation, and reduced transition times between CPR and electrotherapy.

Apparatus for monitoring a cardiac rhythm during CPR

A defibrillator (AED) and method for using a defibrillator using two different ECG analysis algorithms which work sequentially to improve the accuracy of AED shock decisions. A first algorithm, such as (ART), is particularly suited for analysis in the presence of CPR periods. A second algorithm, such as (PAS), is particularly suited for analysis during hands-off periods. The AED switches algorithms depending on the period and on the current analysis of the cardiac rhythm. The inventions thus provide an optimized ECG analysis scheme in a manner that improves the effectiveness of the rescue, resulting in more CPR 'hands-on' time, better treatment of refibrillation, and reduced transition times between CPR and electrotherapy.

Automated external defibrillator (AED) with dual ECG analysis algorithms

An automatic external defibrillator (AED) is described which is leased for an at-risk patient and designed for use in a single cardiac emergency. If the AED is in standby for a year without being deployed, the AED is removed from service and replaced with another AED. The AED requires a rescuer only to deploy the electrodes on the torso of the victim; the AED turns itself on, performs rhythm analysis and delivers a shock if needed automatically. The AED thus requires no user controls. Preferably the AED requires no on-site maintenance, as the AED communicates its readiness for use to a remote monitoring site which responds to any problems detected by self-testing. In addition to its electro-resuscitation function, the AED can be used on the chest of the victim to administer CPR compressions.

Single use AED

An automated external defibrillator (AED) is described which includes two electrocardiogram (ECG) analyzers. One of the ECG analyzers is suitable for use only for ECG which is signal-noise-free, and thus may be used during 'hands-off' analysis periods in which no cardiopulmonary resuscitation (CPR) compressions can be provided. The length of the 'hands-off' analysis period can be shortened by use of the second ECG analyzer in concert with the first ECG analyzer. Thus, a greater proportion of CPR time through the course of a cardiac arrest rescue is achieved.

Automated external defibrillator with shortened pause for rhythm analysis

A method and associated apparatus () detects the presence and quality of chest compressions during cardiopulmonary resuscitation (CPR) by analyzing existing signals in automated external defibrillator (AED) devices without using a stand-alone CPR meter. The method includes analyzing both a thoracic impedance signal and a common-mode current signal, each of which can be measured with standard AED pads (). The method applies criteria to the measured signals, the criteria being used to select which of the measured signals to use for providing CPR chest compression detections.

Method and apparatus for detecting a status of CPR chest compressions without using a stand-alone compression meter

A defibrillator and method for using a defibrillator which adopts an ECG analysis algorithm that can detect a cardiac arrhythmia in the presence of noise artifact induced by cardio pulmonary resuscitation (CPR) compressions. The apparatus and method provides both of a continuous and scheduled mode of operation for interleaving periods of CPR with electrotherapy, in a manner that improves the effectiveness of the rescue, resulting in more CPR 'hands-on' time, better treatment of refibriUation, and reduced transition times between CPR and electrotherapy.

Defibrillator with scheduled and continuous modes of operation

A defibrillator and method for using a defibrillator which adopts an ECG analysis algorithm that can detect a cardiac arrhythmia in the presence of noise artifact induced by cardio pulmonary resuscitation (CPR) compressions. The apparatus and method includes a confidence analyzer circuit which determines the confidence level of an electrotherapy shock decision based on the detection. If the confidence level is low, the apparatus adjusts its shock decision criteria.

Confidence analyzer for an automated external defibrillator (AED) with dual ECG analysis algorithms

An automatic external defibrillator (AED) is described which is designed for use in a single cardiac emergency. If the AED is in standby for a year without being deployed, the AED is removed from service and replaced with another AED. The AED requires a rescuer only to deploy the electrodes on the torso of the victim; the AED turns itself on, performs rhythm analysis and delivers a shock if needed automatically. The AED thus requires no user controls. Preferably the AED requires no on-site maintenance, as the AED communicates its readiness for use to a remote monitoring site which responds to any problems detected by self-testing. In addition to its electro-resuscitation function, the AED can be used on the chest of the victim to administer CPR compressions.

A method for delivering electrotherapy from a defibrillator includes the steps of providing a source of patient ECG signals received during a CPR period, estimating from the patient ECG signals the likelihood of a shockable rhythm existent during the CPR period, and determining whether CPR should be interrupted prior to the end of the CPR period to deliver electrotherapy based on the estimating step. Based on the determining step, the defibrillator may then provide an output instruction to stop CPR. The AED () thus enables an improved rescue protocol.

Defibrillator with protocol for selectively interrupting CPR

An automated external defibrillator (AED) () having a treatment decision processor () is described which follows a 'shock first' or a 'CPR first' rescue protocol after identification of a treatable arrhythmia, depending upon an estimate of the probability of successful resuscitation made from an analysis of a patient parameter measured at the beginning of the rescue. The invention may also follow different CPR protocols depending on the estimate. The invention also may use the trend of the measured patient parameter to adjust the CPR protocol either during a CPR pause or after the initial CPR pause. The AED () thus enables an improved rescue protocol.
