Why the study?
Does a single shock with a biphasic defibrillator plus immediate CPR improve survival in patients with sudden cardiac arrest compared to historical 3-shock sequences?
Does a single shock with a biphasic defibrillator plus immediate CPR improve survival in patients with sudden cardiac arrest compared to historical 3-shock sequences?
Guidelines recommend single shocks with biphasic defibrillators followed immediately by CPR for sudden cardiac arrest to minimize interruptions in chest compressions and improve survival.

Single biphasic shock plus immediate CPR should replace stacked shocks in VF arrest; extends high first-shock efficacy data into updated resuscitation guidelines.
Link et al. (2010) conducted a review in Sudden cardiac arrest and life-threatening arrhythmias. Single shocks plus immediate CPR using biphasic defibrillators vs. 3-shock sequences was evaluated on Survival from sudden cardiac arrest. Newer biphasic defibrillators with high first-shock efficacy led to the recommendation of single shocks plus immediate CPR instead of 3-shock sequences to treat ventricular fibrillation.
