About Real CPR Help


While only 50% of sudden cardiac arrest victims will initially need a shock, 100% will require CPR to increase the flow of oxygenated blood to the heart and brain.

ZOLL® AEDs with Real CPR Help® let rescuers know when they are performing high-quality CPR. Integrated real-time feedback eliminates guesswork and keeps rescuers on track; it provides rescuers with visual and audio prompts to “Push Harder” or will let them know when they are doing “Good Compressions.”

Why Real-Time CPR Feedback Matters

The European Resuscitation Council (ERC) and the Resuscitation Council (UK) emphasise the importance of high-quality CPR as being vital to the successful outcome of an attempt to resuscitate a victim of sudden cardiac arrest. It is also understood that the delivery of high-quality CPR is particularly difficult to perform consistently over a prolonged period of time. In most emergencies, the quality of CPR provided by the rescuer can make the difference between life and death.

What if you knew real time how well you are performing CPR?

What if a defibrillator could tell you that you are doing good chest compressions?

What if you could capture all that data for CPR review, training and analysis? 

Can all this be possible? With ZOLL AEDs, the answer is yes.

ZOLL's exclusive Real CPR Help technology provides integrated real-time feedback on CPR depth and rate to help provide high quality CPR in accordance with the most recent guidelines.

How Real CPR Help Works

  • Not pushing hard enough? It will tell you when to “Push harder.”
  • Pushing hard enough? It will say, "Good compressions."
  • Not pushing fast enough? A metronome will lead you to the right rate.
  • It will even show you the depth of each compression — in real time
  • Not yet started? The ZOLL AED Plus® defibrillator will tell you to get started.
  • Compressions stopped? It will tell you to continue.
