Study summary

It's so important to recognize ventricular fibrillation in cardiac arrest and defibrillation early. At the same time Research findings have identified high-quality CPR with minimum interruption is critical to the success of defibrillation therapy. Both the guidelines by American Heart Association and the guidelines by European Resuscitation Council emphasize the importance of minimizing interruptions in chest compressions, specifically, duration of the pre-shock and post-shock pauses. So AHA indicate that there will be a new algorithm of VF during chest compression, which has high sensitivity and specificity. And the investigators can identify VF and defibrillate earlier.

The aim of this study is to verify that if Sherlock algorithm of Philips MRx monitor/defibrillator can identify shockable rhythms during chest compression accurately.

Primary outcomes

  1. Sensitivity and specificity of Sherlock algorithm of Philips MRx monitor/defibrillator in identify ventricular fibrillation.

    Time frame: 04/10/2016-10/01/2017

  2. How long it is advanced that the first time Sherlock algorithm identified VF than the true time VF was recognized.

    Time frame: 04/10/2016-10/01/2017

  3. Comparasion of no-flue time between true scene and assumed scene that useing Sherlock algorithm.
