Importance of Real-Time CPR Feedback Presented at AHA Scientific Sessions 2009

Zoll Medical Corporation (NasdaqGS: ZOLL) announced today that the importance of real-time feedback to improve the quality of CPR was presented in two separate poster presentations at the American Heart Association 2009 Scientific Sessions in Orlando, Florida this week. ZOLL’s exclusive real-time feedback technology, Real CPR Help^®, is now available in virtually all of the Company’s defibrillators, AEDs and its PocketCPR^® device to help improve CPR performance and outcomes in victims of sudden cardiac arrest (SCA).

Charles N. Pozner, M.D., Director of STRATUS Center for Medical Simulation, Brigham & Women’s Hospital, Boston, and David Barash, M.D. Concord Healthcare Strategies, Concord, Mass., et al., presented "Early Marker of Rescuer Fatigue,” citing the key conclusion that the CPR feedback device (PocketCPR) provided objective and reliable measurement of chest compression depth and could be an accurate marker of rescuer fatigue. The handheld CPR feedback device significantly improved the quality of chest compressions provided by experienced hospital providers.

The second poster presentation by Drs. Pozner and Barash et al., entitled "Do We Need to Switch Rescuers Every Two Minutes” concluded that with real-time CPR feedback, hospital providers could perform chest compressions for four minutes without degradation in the depth of compressions, thus allowing for fewer interruptions to switch rescuers.

"We are greatly encouraged that an increasing number of studies are seeing the value of ZOLL’s technology that provides rescuers with prompts and measurements that improve CPR quality,” said Richard A. Packer, President and CEO of ZOLL. "Our key focus has been to help improve outcomes from sudden cardiac arrest, and supporting research from clinicians is an important indication of the strides we are making.”
