The ZOLL RBW Difference: Real Performance ZOLL’s Rectilinear Biphasic™ waveform (RBW) was specifically designed for external defibrillation to control for variations in patient impedance. By delivering a constant amount of current, the ZOLL RBW delivers the right “dose” for every patient. At 200 J, the ZOLL RBW delivers more current to high impedance patients than any other biphasic device—even ones that escalate to 360 J. Don’t Be Fooled by Energy: Current Defibrillates “The essential requirement for electrical ventricular defibrillation is the attainment of a sufficient current density.”...

High Energy Does Not Mean More Current Waveform Comparison In the diagram on the right, Waveform “B” has more energy than Waveform “A,” but actually delivers less current. Here’s why: Energy (joules) is simply the work required to get current to the heart; it’s the product of three variables: Current (amps) 14 Joules = Voltage x Current x Time By extending duration (time), as in Waveform “B,” you can deliver more energy. But you only create the illusion of more capability because you have not necessarily delivered more current—or more efficacy. B 0 Total Duration (msec) Once duration...

The Most Clinical Evidence— The Only Superior Waveform All biphasic waveforms are not superior to monophasic waveforms. The fact is, only the ZOLL RBW has demonstrated statistical clinical superiority14 to monophasic waveforms in peerreviewed, randomized, controlled trials. And now, with data from more than 2,800 patients, you can feel secure in the strength of the RBW evidence.

Superiority for Cardioversion of Atrial Fibrillation Again, only the ZOLL RBW showed statistically significant improvement over MDS at every incremental energy level and for cumulative efficacy.19-21 100 19% increase 13% increase 7% increase % Efficacy • 68% of patients were cardioverted at 70 J with the ZOLL RBW on the first shock, as compared to only 21% of those receiving an MDS shock at 100 J (p=0.0001). • There was a 19% increase in cumulative efficacy over MDS (94% vs. 79%, p=0.005). • AF superiority has been confirmed in 4 separate clinical trials representing more than 1,200...

Leadership in Defibrillation and Resuscitation • The performance of ZOLL’s RBW has been confirmed in over a dozen clinical trials involving more than 2,800 patients. • ZOLL’s RBW has the highest defibrillating current for patient impedance ≥75 ohms of any biphasic waveform, delivered over the optimal duration. • Only ZOLL’s RBW has the clinical data to support labeling 27 as clinically superior to monophasic waveforms for the cardioversion of AF, and the conversion of VF in high impedance patients.
