In cardiac arrest care it is well accepted that time to defibrillation is closely correlated with survival and outcome.1 There has also been a lot of focus over the years on limiting interruptions in chest compressions during CPR. In fact, this concept has become a major focus of the current AHA Guidelines. Why? Because we know interruptions are bad.2,3 One particular aspect of CPR that has gotten a lot of attention in this regard is the peri-shock period. It has been well established that longer pre- and peri-shock pauses are independently associated with decreased chance of survival.4,5 Can we do better to shock sooner and minimize these pauses?
