Abstract
An automated resuscitation system is provided, which can improve the outcome of patients suffering ventricular fibrillation or the ventricular tachycardia variants of cardiac arrest. This outcome can be achieved by a device that integrates automatic mechanical or pneumatic capability with electrical countershock capability such that the probability of defibrillation or cardioversion with return of spontaneous circulation is increased.
Claims20
An automated resuscitation system (ARS) comprising:
- at least one means for compression of the chest that produces forward blood flow;
- a countershock defibrillation subsystem;
- a plurality of countershock electrodes on patient facing portions of the ARS;
- electrode contact pressure enhancers;
- and
- a control system adapted to synchronize chest compressions and countershocks, wherein the control system alters the patterns of ventilation and electrical countershock such that electrical countershock is within one second of end-expiration.
An automated resuscitation system (ARS) comprising:
- at least one means adapted for applying pressure to a chest to produce blood flow;
- a countershock defibrillator subsystem;
- a plurality of countershock electrodes on patient facing portions of the ARS;
- a ventilation subsystem;
- and
- a control system adapted to synchronize chest compressions, countershocks, and ventilation, wherein that electrical countershock occurs at end-expiration lung volume.
An automated resuscitation system (ARS) comprising:
- at least one means for compression of the chest that produces forward blood flow;
- a countershock defibrillation subsystem;
- a plurality of countershock electrodes on patient facing portions of the ARS;
- electrode contact pressure enhancers;
- and
- a control system adapted to synchronize chest compressions and countershocks, wherein the at least one means for compression inflates a circumferential series of bladders, wherein portions of the circumferential series of bladders over the countershock electrodes may be individually inflated.
An automated resuscitation system (ARS) comprising:
- at least one means for compression of the chest that produces forward blood flow;
- a countershock defibrillation subsystem;
- a plurality of countershock electrodes on patient facing portions of the ARS;
- electrode contact pressure enhancers;
- and
- a control system adapted to synchronize chest compressions and countershocks, wherein the means adapted for applying pressure to the chest is adapted to deliver a first compression-decompression pattern optimized for producing forward blood flow, and a second compression-decompression pattern optimized for increasing the efficacy of electrical countershock.
An automated resuscitation system (ARS) comprising:
- at least one means for compression of the chest that produces forward blood flow;
- a countershock defibrillation subsystem;
- a plurality of countershock electrodes on patient facing portions of the ARS;
- electrode contact pressure enhancers;
- and
- a control system adapted to synchronize chest compressions and countershocks, wherein an overall pattern of the compression may be released by a first portion of the at least one means for compression so as to allow onset of the chest decompression, and wherein compression is maintained in a second portion of the at least one means for compression, the second portion located over the countershock defibrillation electrodes, so as to enhance electrode contact pressure.
