Study Released at AHA Shows Survival to Hospital Discharge After Cardiac Arrest Doubles With Improved CPR and Impedance Threshold Device

Date:11/6/2007

Groundbreaking study looks at hospital discharge rates in seven cities,

including Largo, Fla.

ORLANDO, Fla., Nov. 6 /PRNewswire/ -- A new seven-city study on the impact of new CPR techniques supports the widespread use of the American Heart Association's new 2005 CPR guidelines, according to the study authors in a presentation at the AHA's Scientific Sessions on November 4 in Orlando. Lead author, Tom P. Aufderheide, MD, Professor of Emergency Medicine and Director of the Resuscitation Research Center in the Department of Emergency Medicine at the Medical College of Wisconsin in Milwaukee, presented the data showing a doubling of hospital discharge rates when the AHA's new CPR guidelines were consistently and effectively applied to 893 patients.

The EMS departments submitting data in the study tracked individuals who experienced cardiac arrest outside of the hospital all the way through hospital discharge. When subjects were treated with new CPR techniques including the use of the ResQPOD, an impedance threshold device (ITD), the hospital discharge rates jumped from 7.9 percent to 15.7 percent, or double the survival rate of the control group.

Aufderheide said, "This menu of interventions for patients with cardiac arrest has resulted in one of the highest overall survival rates ever documented for this devastating medical condition. It represents a major breakthrough in the treatment of cardiac arrest, which we hope will be disseminated in other systems throughout the United States."

The seven EMS departments participating in the study used AHA-recommended new CPR including increased compressions, full chest wall recoil and use of the impedance threshold device. The ResQPOD ITD is a $99 device manufactured by Advanced Circulatory Systems (ACS). The impedance threshold device received a Class IIa rating by the AHA in its 2005 Emergency Cardiac Care Guidelines. This is the highest recommendation possible given
