Survival of Cardiac Arrest more than doubles with Real CPR Help® technology
The Influence of Scenario-Based Training and Real-Time Audiovisual Feedback on Out-of-Hospital Cardiopulmonary Resuscitation Quality and Survival From Out-of-hospital Cardiac Arrest by Prof. Bentley J. Bobrow
The study tracked 484 cardiac arrest patients, and had two phases. Phase one included 232 patients who were defibrillated and given standard manual CPR. Medics were trained in high-quality CPR before phase two, which included 252 patients who were treated with defibrillation and given CPR utilising ZOLL’s Real CPR Help® technology.
The study produced some fantastic results supporting the use of ZOLL’s Real CPR Help, which is incorporated into the ZOLL AED Plus® defibrillator as outlined below:
- Average chest compression depth increased from 1.78 inches in Phase 1 to 2.15 inches in Phase 2 – (AHA & ERC guidelines recommend between 2 and 2.5 inches)
- Average rate of compressions decreased from 128 per minute in Phase 1 to 106 in Phase 2 – (the optimum rate is 100 per minute).
- Time performing chest compressions increased from 66% in Phase 1 to 84% in Phase 2.
Cardiac arrest victims receive more and better CPR from trained first responders using defibrillators equipped with ZOLL’s Real CPR Help technology. Victims of cardiac arrest defibrillated
It is the first study to prove that ZOLL’s Real CPR Help technology, in addition to helping improve rescuers’ CPR, significantly improves survival rates from cardiac arrest.
Casualties treated with ZOLL defibrillators incorporating Real CPR Help are more than twice as likely to survive when compared with those treated without Real CPR Help. Real CPR Help saves more lives.
All of the above resulted in dramatic improvements in cardiac arrest survival rates. This study conclusively proves that everything we have been saying about the correlation between good quality CPR and cardiac arrest survival is true. It also highlights that whilst defibrillation plays an important role, it is only part of the overall chain of survival.
