Intellisense™ CPR (ICPR) Technology

Why do I need the Powerheart® G5 AED with ICPR?

The AHA, ERC, and other resuscitation councils have determined that administering high-quality CPR improves a victim’s chance of survival from cardiac arrest.1 In addition to minimizing pauses between compressions and avoiding excessive ventilation, there are three other important guidelines to delivering high-quality CPR for patients 8 years and older:

  1. Ensuring that compression rate is between 100–120 per minute
  2. Ensuring that compression depth is between 2–2.4 inches (5–6 centimeters)
  3. Allowing full chest recoil between compressions

Delivering consistent, high-quality CPR compressions within resuscitation guidelines can be difficult, especially in stressful rescue situations. To help both professional and lay rescuers deliver the best quality CPR, the ZOLL Powerheart G5 AED comes equipped with Intellisense CPR (ICPR) technology. ICPR features a unique motion sensor and a proprietary algorithm that monitors the performance of CPR compressions and provides real-time, guideline-driven feedback to help rescuers provide high-quality CPR.

If compressions deviate from the guidelines for high-quality CPR, the AED will provide corrective prompts via voice and text to guide the rescuer in providing the best CPR possible.

Compression rate

A metronome guides rescuers in achieving compression rate targets. With the ICPR sensor, voice and text corrections alert rescuers when the compression rate falls outside the guidelines. This powerful combination of coaching and feedback keeps rescuers on pace to deliver optimal compressions.

Compression depth

Pressing too hard? Not hard enough? The ICPR system utilizes a non-slip, motion-sensing disc, placed in the center of the chest, to monitor the depth of compressions. The feedback system helps the rescuer achieve the target 2–2.4-inch (5-6cm) compression depth. 

Chest recoil

The ICPR system also provides a prompt reminding rescuers to fully release between compressions. According to resuscitation guidelines,1 “Observational studies indicate that leaning (on the chest wall) is common during CPR in adults and children.”2 It is critical to prevent this common error in CPR. Resuscitation guidelines also report, “Leaning on the chest wall between compressions precludes full chest wall recoil... and could potentially influence resuscitation outcomes.”1

The ICPR technology integrated in the ZOLL Powerheart G5 AED is designed to support rescuers with real-time, guideline-driven feedback, helping them deliver the most effective CPR to increase the chance of survival from SCA.
