Feb. 28, 2013 /PRNewswire/ -- Cardiopulmonary resuscitation (CPR) training that included real-time audiovisual feedback and that emphasized a "pit crew" or team approach to pre-hospital care for cardiac arrest patients increased survival by almost 60 percent. The results of a clinical trial of scenario-based training were published online yesterday in
Annals of Emergency Medicine ("The Influence of Scenario-Based Training and Real-Time Audiovisual Feedback on Pre-hospital Cardiopulmonary Resuscitation Quality and Survival from Out-of-Hospital Cardiac Arrest")

"Ours is the first study to demonstrate an association between a dedicated CPR quality initiative using real-time audiovisual feedback and out-of-hospital cardiac arrest outcomes," said lead study author
Bentley Bobrow, MD, FACEP of The
University of Arizona College of Medicine in
Phoenix, Ariz. "It is also the first to show an association between performance of the 2010 American Heart Association CPR quality metrics and increased survival for out-of-hospital cardiac arrest."
Mesa Fire and Medical Department in
Mesa, Arizona implemented 2 hours of didactic teaching, 2 hours of scenario-based training and activation of real-time audiovisual feedback. Training emphasized a team approach to resuscitation, assigning each member of the team a role in a "'pit crew' model of resuscitation."
CPR quality measures improved significantly after the training protocol was established. Chest compressions decreased from 128 to 106 per minute. Chest compression depth increased from 1.78 to 2.15 inches. Other measures improved similarly. Survival for all groups increased from 8.7 percent to 13.9 percent. For patients with shockable rhythms whose arrest was witnessed, survival more than doubled, from 26.3 percent to 55.6 percent.
