x Fully Automatic AED Plus Administrator’s Guide
Introduction Using the Fully Automatic AED Plus The Fully Automatic AED Plus is an automatic external defibrillator (AED) that uses voice prompts and visual indicators to guide the rescuer through a resuscitation sequence that may include defibrillation and/or cardiopulmonary resuscitation (CPR). The unit incorporates the ZOLL Rectilinear Biphasic Defibrillation waveform, and operates in either adult or pediatric mode.
Using Real CPR Help ® The CPR-D-padz include a sensor that detects the rate and depth of CPR chest compressions. This sensor is placed (as part of the electrodes application) on the victim’s chest so that it is located between the rescuer’s hands and the victim’s lower sternum during chest compressions. When the rescuer performs CPR compressions, the sensor detects their rate and depth and sends the information to the Fully Automatic AED Plus unit.
Operation This section describes the following functions: • Operating Controls and Indicators • Using the Fully Automatic AED Plus Graphical User Interface • Voice Prompts • Using the LCD Display • Using the Passive Airway Support System (PASS) • Using Electrodes • Applying CPR-D-padz • Applying pedi-padz II (Infant/Child Electrodes) • Using the CPR Monitoring Function — Real CPR Help • Using the Audio Recording Option Operating Controls and Indicators See Table 1: Control Functions for an explanation of e

Using the Passive Airway Support System (PASS) If there is no evidence of head or neck trauma, the head tilt chin lift method is the recommended maneuver for opening the airway. The PASS may be placed under the victim’s shoulders to help maintain head tilt. WARNING! DO NOT use PASS if suspected head or neck injury. Place victim on a firm surface before performing CPR.
Using Electrodes WARNING! DO NOT reuse electrodes. The Fully Automatic AED Plus supports both adult and pediatric electrode pads. The device automatically adjusts defibrillation energy to adult or pediatric levels depending on the type of electrodes connected to it. Make sure that the electrode pads used are appropriate for the victim. WARNING! DO NOT use adult electrode pads or CPR-D-padz on victims under 8 years of age.
Applying CPR-D -padz Prepare the victim before attaching the electrodes. WARNING! CPR-D-padz are intended for use on adult victims only; do not use on victims under 8 years of age. To prepare the victim: 1. Remove all clothing covering the victim’s chest. 2. Ensure the victim’s chest is dry. 3. If the victim has excessive chest hair, clip or shave the hair to help ensure proper adhesion of the electrodes. To apply the electrodes: 1. Tear open the electrode package and unfold the electrodes.
Applying pedi-padz II (Infant/Child Electrodes) Prepare the victim before attaching the electrodes. To prepare the victim: 1. Remove all clothing covering the victim’s chest. 2. Ensure the victim’s chest is dry. To apply the electrodes: 1. Tear open the electrode package and unfold the inner package to expose the electrodes. Place the electrodes on the victim according to the graphics on the package (see Figure 6). 2.
Using the CPR Monitoring Function — Real CPR Help When used with ZOLL CPR-D-padz, the Fully Automatic AED Plus monitors the rate and depth of CPR chest compressions. The Fully Automatic AED Plus provides a CPR adaptive metronome function designed to encourage rescuers to perform chest compressions at the AHA/ERC recommended rate of 100 compressions per minute. Voice and visual prompts encourage a a minimum compression depth of 2 inches for adult victims.

Clinical Trial Results for the M Series Biphasic Waveform The efficacy of ZOLL’s Rectilinear Biphasic Waveform has been clinically verified during a study of defibrillation of Ventricular Fibrillation (VF)/Ventricular Tachycardia (VT). A feasibility study was performed initially for defibrillation of VF/VT (n=20) on two separate groups of patients to ensure waveform safety and energy selection. Subsequently a separate, multi-center, randomized clinical trial was performed to verify the waveform’s efficacy.
The difference in efficacy between the rectilinear biphasic and the monophasic shocks was greater in patients with high transthoracic impedance (greater than 90 ohms). The first shock, first induction efficacy of biphasic shocks was 100% versus 63% for monophasic shocks for patients with high impedance (p=0.02, 95% confidence interval of the difference of -0.021% to 0.759% and 90% confidence interval of the difference of 0.037% to 0.706%).
ECG Analysis Algorithm Accuracy Sensitivity and specificity are expressions of ECG analysis algorithm performance when compared to ECG interpretation by a clinician or expert. Sensitivity refers to the algorithm’s ability to correctly identify shockable rhythms (as a percentage of the total number of shockable rhythms); specificity refers to the algorithm’s ability to correctly identify non-shockable rhythms (as a percentage of the total number of non-shockable rhythms).
