Real CPR Help

ZOLL Defibrillators Provide Feedback for High-Quality CPR

The evidence is indisputable: high-quality CPR is the primary component in influencing survival from cardiac arrest.1 Not every patient will need a defibrillating shock, but every patient will need CPR.

ZOLL® introduced Real CPR Help® in 2002, and it’s standard on all our monitors and defibrillators: ZOLL AED 3®, AED Plus®, AED Pro®, R Series® and X Series® Advanced.

Even for seasoned health care professionals, it’s hard to know if you are pushing hard enough and fast enough to meet current Resuscitation Guidelines for compression rate and depth. With Real CPR Help, you know. It provides audio and visual feedback that guides rescuers to deliver high-quality CPR. 

How Real CPR Help Guides Resuscitation

Using accelerometer technology, a sensor inside ZOLL’s CPR electrodes captures the rate and depth of each compression. Once the electrodes are placed on the patient, the person providing CPR presses on the clearly marked hand placement indicator that covers the sensor. The information captured is sent to the defibrillator, where it is immediately processed and provided in real time to the rescuer. 

Compression Rate and Depth Feedback Provides Just Enough Help

On the AED Plus, ZOLL AED 3, and the AED Pro defibrillators, rescuers will hear — and see — “Push Harder” or “Good Compressions,” as well as encouragement to “Start CPR” if needed. On  the R Series and the X Series Advanced, Real CPR Help provides numeric displays of both rate and depth, as well as verbal feedback, if desired, to “Push Harder” or “Good Compressions.” Thanks to Real CPR Help, more detailed information about CPR quality can be displayed on the CPR Dashboard™ on the R Series and X Series. 

In addition, on all ZOLL AEDs and professional defibrillators, an adaptive metronome will guide you to provide the Guidelines-recommended rate of compressions. What you see and/or hear will depend on how your device is configured.

On the AED Plus, rescuers will hear the prompt “Push Harder” or “Good Compressions,” and the same message will appear on the AED screen.

Inadequate versus good compressions on the X Series and R Series

On the X Series Advanced and R Series (shown above), CPR Dashboard provides the actual depth and rate of the compressions, as well as a compression release indicator so you know if you’re coming off the chest to allow for full recoil, and a PPI, or Perfusion Performance Indicator. If the indicator is completely full, you know that both depth and rate of compressions are within Guidelines.

Chances of Survival After Sudden Cardiac Arrest More than Doubled

Studies in Arizona and California prove that high-quality CPR saves lives and that Real CPR Help can improve CPR quality.2,3 A large study of EMS providers in Arizona showed that the odds of survival increased 2.7 times with ZOLL’s industry-exclusive Real CPR Help and scenario-based training.2 Additionally, survival to discharge and good neurological outcomes doubled after the implementation of a “resuscitation bundle” at the University of California San Diego Medical Center that included Real CPR Help and specialised training.3

Real CPR Help gives rescuers at every experience level real-time CPR feedback to provide high-quality CPR and the confidence that they are providing the best CPR possible.
