Indications for Use
The ZOLL M Series Bi-Phasic Defibrillator is to be used only by qualified medical personnel for converting ventricular fibrillation (VF), a cardiac rhythm incompatible with life, and/or Ventricular Tachycardias (VT) to sinus rhythm or other cardiac rhythms capable of producing hemodynamically significant heart beats. In addition, this product is to be used in the synchronized cardioversion mode only by qualified medical personnel to terminate Atrial Fibrillation (AF) at lower energy and currents than monophasic defibrillators. A qualified physician must decide when synchronized cardioversion is appropriate. In addition, this product is to be used in the synchronized cardioversion mode only by qualified medical personnel to terminate Ventricular Tachycardias (VT). A qualified physician must decide when synchronized cardioversion is appropriate. The Rectilinear Biphasic Waveform (RBW) has been successfully tested in multi-center, prospective, randomized, transthoracic defibrillator VT/VF and AF clinical trials, proven to defibrillate and cardiovert adult patients at lower energies and currents than existing monophasic devices. The M Series Biphasic option incorporates some user selectable energy settings, which are lower than those used during those clinical trials. There are currently no clinical studies related to the Rectilinear Biphasic Waveform (RBW) in pediatic applications. The AED or advisory function should only be used to confirm the presence of ventricular fibrillation in patients meeting the following clinical criteria: - the patient should be unconscious and unresponsive ● - the patient should be apneic (not breathing) ● - the patient should be pulseless . Do not use the units AED function on patients under the 8 years of age. (Per AHA Guidelines for Adult Warning Cardiopulmonary Resuscitation and AED, 3-5, 1998).
Device Story
ZOLL M Series Bi-Phasic Defibrillator delivers electrical therapy to convert cardiac arrhythmias (VF, VT, AF) to sinus rhythm. Device utilizes Rectilinear Biphasic Waveform (RBW) technology to deliver defibrillation and cardioversion at lower energies/currents than monophasic devices. Operated by qualified medical personnel in clinical settings. Includes AED/advisory function to detect VF in unconscious, apneic, pulseless patients. Clinicians use device output (ECG rhythm analysis, therapy delivery) to guide resuscitation and cardioversion decisions. Benefits include effective arrhythmia termination with reduced energy requirements.
Clinical Evidence
Evidence includes multi-center, prospective, randomized, transthoracic clinical trials evaluating the Rectilinear Biphasic Waveform (RBW) for VT/VF and AF. Results demonstrated successful defibrillation and cardioversion in adult patients using lower energies and currents than monophasic devices. No clinical data provided for pediatric applications.
Technological Characteristics
Device utilizes Rectilinear Biphasic Waveform (RBW) technology for electrical therapy delivery. Features user-selectable energy settings. Designed for use by qualified medical personnel. Connectivity and specific material standards not detailed in provided text.
Indications for Use
Indicated for adult patients experiencing ventricular fibrillation (VF), ventricular tachycardia (VT), or atrial fibrillation (AF) requiring defibrillation or synchronized cardioversion. AED function indicated for unconscious, apneic, and pulseless patients aged 8 years and older. Contraindicated for AED use in patients under 8 years of age.
Regulatory Classification
Identification
An automated external defibrillator (AED) system consists of an AED and those accessories necessary for the AED to detect and interpret an electrocardiogram and deliver an electrical shock (e.g., battery, pad electrode, adapter, and hardware key for pediatric use). An AED system analyzes the patient's electrocardiogram, interprets the cardiac rhythm, and automatically delivers an electrical shock (fully automated AED), or advises the user to deliver the shock (semi-automated or shock advisory AED) to treat ventricular fibrillation or pulseless ventricular tachycardia.
