Researchers are looking at specific components of cardiopulmonary resuscitation (CPR) to determine why resuscitation for out-of-hospital cardiac arrest continues to have a low success rate.
New research suggests decreasing the preshock interval, the period between performing chest compressions during CPR and defibrillation, may help improve resuscitation rates. Researchers with the Resuscitation Outcomes Consortium, a clinical trial network focusing on research in the area of out-of-hospital cardiopulmonary arrest and severe traumatic injury, found that longer preshock periods were associated with decreased likelihood of survival to hospital discharge (Cheskes S et al. Circulation. 2011;124:58-66).
