Real CPR Help

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® technology in 2002, and it’s standard on every AED (automated external defibrillator) and professional defibrillator ZOLL sells.

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

See Real CPR Help technology in action in this online demo.

How Real CPR Help Works

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.

Just Enough Help

On the ZOLL AED 3®AED Plus®AED 3® BLS, and AED Pro® defibrillators, rescuers will hear — and see — “Push Harder” or “Good Compressions,” as well as encouragement to “Start CPR” if needed.

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.

Push harder Good compressions

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

CPR Overview

When someone experiences sudden cardiac arrest (SCA), survival depends on bystanders quickly intervening to provide cardiopulmonary resuscitation (CPR) and other lifesaving measures until emergency medical services arrive. A rescuer delivering CPR compresses a victim’s chest to perfuse the heart, brain, and other vital organs with oxygenated blood. Some form of manual ventilation may also be provided until the victim shows signs of the return of spontaneous circulation (ROSC), such as breathing, coughing, or a measurable pulse.
