ZOLL® offers many clinically advanced defibrillators and AEDs to help you improve survival from sudden cardiac arrest (SCA).

Why Defibrillation Matters

Early defibrillation and CPR are two critical components in treating sudden cardiac arrest. Speed to therapy as well as high-quality CPR are essential to improving outcomes. All of our manual defibrillators and automated external defibrillators feature Real CPR Help®, which provides real-time coaching and CPR feedback on rate and depth of chest compressions. And an AED mode on our R Series® defibrillator encourages BLS responders to apply electrodes and delivery therapy if needed while waiting for the ALS team.

How ZOLL Defibrillator Devices Work

Current defibrillates the heart and helps to restore normal sinus rhythm. The goal of a defibrillation shock is to deliver the appropriate amount of current at the right time. 

All ZOLL defibrillators and AEDs feature our proprietary Rectilinear Biphasic™ waveform (RBW) technology – the only biphasic waveform that has demonstrated clinically superior results as compared to monophasic waveforms for:

  • Cardioversion of atrial fibrillation
  • Defibrillation of ventricular fibrillation in high-impedance patients
  • Defibrillation of ventricular fibrillation in out-of-hospital cardiac arrest in an ACLS environment*

At 200 joules, the ZOLL RBW delivers more average current to high-impedance patients than any other biphasic waveform—even ones that have higher energy settings.

"The essential requirement for electrical ventricular defibrillation is the attainment of a sufficient current density."1

*The data demonstrate the equivalent efficacy of low-energy rectilinear biphasic shocks compared to standard high-energy monophasic shocks for transthoracic defibrillation for all patients in VT/VF at the 95% confidence level. The data also demonstrate the superior efficacy of low-energy rectilinear biphasic shocks compared to standard high-energy monophasic shocks in patients in VT/VF with high transthoracic impedance at the 90% confidence level.
