The purpose of this prospective observational cardiopulmonary resuscitation (CPR) registry is to track the use and clinical outcomes from emergency medical systems across the US and Europe that have implemented a system of care approach applied rapidly to cardiac arrest that includes using the combination of an impedance threshold device (ITD), and either manual active compression-decompression (ACD) CPR device or automated compression device, with a Head Up CPR device.
Patient is at least 18 years of age
Patient is in active cardiac arrest, as defined by presence of either ventricular fibrillation or ventricular tachycardia, or pulseless electrical activity, or asystole at time of enrollment.
Patient receives either a) active-compression decompression cardiopulmonary resuscitation b) automated suction-cup based CPR with an impedance threshold device (ITD) c) manual CPR with an ITD
Subject receives device assisted controlled elevation of the head and thorax.
