## Indications for use
Defibrillator Function The E Series products contain a DC defibrillator capable of delivering up to 200 joules of energy. It may be used in synchronized mode to perform synchronized cardioversion by using the R-wave of the patient's ECG as a timing reference. The unit uses paddles or disposable, pre-gelled, MFE Pads for dle fibrillation. The E Series products must be prescribed for use by a physician or medical advisor of an emergency response team. Do not use the unit's AED function on patients under 8 years of age. Intended Use - Manual Operation Use of the E Series products in the Manual mode for defibrillation is indicated on victims of cardiac arrest where there is apparent lack of circulation as indicated by these three conditions: * Unconsciousness * Absence of breathing, and * Absence of pulse. This product should be used only by qualified medical personnel for converting ventricular fibrillation and rapid ventricular tachycardia to sinus rhythm or other cardiac rhythms capable of producing hemodynamically significant heart beats. In Manual mode, the E Series unit may also be used for synchronized cardioversion to terminate atrial fibrillation (AF) or ventricular tachycardias (VT) by using the R-wave of the patient's EGG as a timing reference. A qualified physician must decide when synchronized cardioversion is appropriate. The Advisory function should be used to confirm ventricular fibrillation and wide complex ventricular tachycardia (greater than 150 beats per minute) in patients meeting the three conditions indicating lack of circulation (previously listed). Intended Use - Semiautomatic Operation (AED) The E Series AED unit is designed for use by emergency care personnel who have completed training and certification requirements applicable to the use of a defibrillator where the device operator controls delivery of shocks to the patient. They are specifically designed for use in early defibrillation programs where the delivery of a defibrillator shock during resuscitation involving CPR, transportation, dnid definitive care are incorporated into a medically-approved patient care protocol. Use of the device in the Semiautomatic mode for defibrillation is indicated on victims of cardiac arrest where there is apparent lack of circulation. Intended Use - CPR Monitoring The CPR monitoring function provides visual and audio feedback designed to encourage rescuers to perform chest compressions at the AHN/ERC recommended rate of 100 compressions per minute. Voice and visual prompts encourage a minimum compression depth of at least 1.5 (3.8 cm) or 2.0 inches (5.0 cm), depending on the configuration, for adult patients. The CPR monitoring function is not intended for use on patients under 8 years of age. Intended Use - Pacemaker This product may be used for temporary external cardiac pacing in conscious or unconscious patients as an alternative to endocardial stimulation. Note: This device must not be connected to internal pacemaker electrodes. The purposes of pacing include: Resuscitation from standstill or bradycardia of any etiology Noninvasive pacing has been used for resuscitation from cardiac standstill, reflex vagal standstill, drug induced standstill (due to procainamide, quinidine, digitalis, b-blockers, verapamil, etc.) and unexpected circulatory arrest (due to anesthesia, surgery, angiography, and other therapeutic or diagnostic procedures). It has also been used for temporary acceleration of bradycardia in Stokes-Adams disease and sick-sinus syndrome. It is safer, more reliable, and more rapidly applied in an emergency than endocardial or other tempo-rary electrodes. As a standby when standstill or bradycardia might be expected Noninvasive pacing may be useful as a standby when cardiac arrest or symptomatic bradycardia might be expected due to acute myocardial infarction, drug toxicity, anesthesia or surgery. It is also useful as a temporary treatment in patients awaiting pacemaker implants or the introduction of transvenous therapy. In standby pacing applications, noninvasive pacing may provide an alternative to transvenous therapy that avoids the risks of displacement, infection, hemorrhage, embolization, perforation, phlebitis and mechanical or electrical stimulation of ventricular tachycardia or fibrillation associated with endocardial pacing. Suppression of tachycardia Increased heart rates in response to external pacing often suppress ventricular ectopic activity and may prevent tachycardia. Pediatric Pacing Pacing can be performed on pediatric patients weighing 331bs / 15kg or less using special ZOLL pediatric MFE Pads. Prolonged pacing (inexcess. minutes), particularly in neonates, could cause burns. Periodic inspection of the underi is recommended.
