Rectilinear Biphasic Technology High-Current Rectilinear Biphasic Waveform Improved efficacy with lower energy is the promise of biphasic waveforms. But not all biphasic waveforms are created equal. The high-current ZOLL Rectilinear Biphasic™ waveform (RBW) provides more current than the “high-energy” biphasic others use. This capability is particularly important for the difficult-to-defibrillate, high-impedance patient.High-current Rectilinear Biphasic is the only biphasic waveform that was developed specifically for external defibrillation. Both high-and low-energy biphasic truncated exponential (BTE) waveforms were adapted from internal defibrillation. RBW has been studied extensively in over 7,000 patients and shown to be superior to monophasic. The high-current ZOLL RBW is the only waveform that the FDA has cleared to claim superiority* over monophasic waveforms. 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 What makes the Rectilinear Biphasic Waveform (RBW) Different? The scientific community and defibrillator manufacturers all agree - current defibrillates the heart. "The essential requirement for electrical ventricular defibrillation is the attainment of a sufficient current density." Tacker WA At 200 J, the ZOLL RBW delivers more average current to high impedance patients than any other biphasic waveform - even ones that have higher energy settings. Read on to uncover the unique advantages of ZOLL's Rectilinear Biphasic waveform : Principles of Electricity More Current at 200 J than other biphasic waveforms at 360 J New Control for Patient Impedance Optimal Duration for Defibrillation Shocks Superior for Cardioversion of Atrial Fibrillation Superior for Defibrillation of Ventricular Fibrillation Superior for Defibrillation of Out-of-Hospital Cardiac Arrest Pediatric Biphasic Recommendations Bibliography *The data demonstrates 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.
