Safety Summar y The following section describes general warnings and safety considerations for administrators, rescuers, and patients.

Warnings • Use the AED Plus unit only as described in this manual. Improper use of the device can cause death or injury. • DO NOT use or place the AED Plus unit in service until you have read the AED Plus Operator’s and Administrator’s Guides. • DO NOT use or place the AED Plus unit in service if the unit’s status indicator window (located on the left side of the handle) displays a red “X”. • DO NOT use or place the AED Plus unit in service if the unit emits a beeping tone. • Connect the electrode cable to the AED Plus unit after installing batteries. • Keep the electrode cable connected to the AED Plus unit at all times. • This device should only be used by properly trained individuals. • Only use electrodes labeled “Infant/Child” on children less than 8 years old or weighing less than 55 lbs (25 kg). Use CPR-D-padz® if victim is older than 8 years or weighs more than 55 lbs (25 kg). • Always stand clear of victim when delivering a shock. Defibrillation energy delivered to the victim may be conducted through the victim’s body and cause a lethal shock to those touching the victim. • DO NOT TOUCH the electrode surfaces, the victim, or any conductive material touching the victim during ECG analysis or defibrillation. • Move victim away from electrically conductive surfaces prior to use of equipment. • DO NOT use this unit near or within puddles of water. • Keep the victim as motionless as possible during ECG analysis. • DO NOT use this unit near flammable agents, such as gasoline, oxygen-rich atmospheres or flammable anesthetics. • Avoid radio frequency interference from high-power sources that might cause the defibrillator to interpret cardiac rhythms incorrectly by turning off cell phones and 2 way-radios. • Disconnect non-defibrillation protected electronic devices or equipment from victim before defibrillation. • Dry victim’s chest, if wet, before attaching electrodes. • Apply freshly opened and undamaged electrodes, within the electrode expiration date, to clean and dry skin to minimize burning. • DO NOT place the electrodes directly over the victim’s implanted pacemaker. Pacemaker stimuli may degrade the accuracy of ECG rhythm analyses or the pacemaker may be damaged by defibrillator discharges. • Check labeling inside the AED Plus cover before using the cover as a Passive Airway Support System (PASS) device. Ensure it is intended for this use. • DO NOT use Passive Airway Support System (PASS) if there is a suspected head or neck injury. Place victim on a firm surface before performing cardiopulmonary resuscitation. • DO NOT recharge, disassemble, or dispose of batteries in fire. Batteries may explode, if mistreated. • Do not use or stack the AED Plus unit with other equipment. If the unit is used or stacked with other equipment, verify proper operation prior to use. • Keep the AED Plus unit away from magnetic resonance imaging (MRI) equipment.

ZOLL AED PLUS Administrator’s Guide

Introduction Using the ZOLL AED Plus The AED Plus is an automated 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. The AED Plus supports both adult and pediatric defibrillation electrode pads, and automatically adjusts the defibrillation energy based on the type of electrode pads connected to it. Following attachment of electrodes to a victim’s chest, the defibrillator monitors the electrocardiographic (ECG) rhythm of the victim’s heart, analyzes that rhythm, and determines whether the rhythm is shockable or non-shockable. When needed, defibrillation energy is delivered through these same electrodes. When the unit detects a shockable rhythm, it charges and issues the warning PRESS FLASHING SHOCK BUTTON. The rescuer presses the Shock Button to deliver the shock. The rescuer will then be prompted to perform CPR for a period of 2 minutes, after which the unit automatically initiates a new ECG analysis. The AED Plus has an optional cover that can be used as a PASS (Passive Airway Support System) to support the victim’s neck and shoulders in a position that assists in maintaining an open airway. Some versions also contain disposable accessories (razor, barrier mask, scissors, and a towel). The AED Plus is powered by ten commercially available consumer brand lithium-manganese dioxide batteries. The AED Plus can: • Perform periodic self tests to ensure its continual readiness. • Use a one-piece electrode assembly (CPR-D-padz) that facilitates proper electrode placement and that is easy to apply to the victim. • Analyze heart rhythm and inform the rescuer if the rhythm is shockable or non-shockable. • Deliver defibrillation treatment to victims of cardiac arrest who exhibit shockable ECG rhythms. • Provide voice prompts and graphics to guide the rescuer regarding what to do and when to do it during a cardiac emergency, such as calling for help or giving CPR to the victim. • Provide audible beeps to encourage rescuers to provide CPR compressions at 100-120 CPM (requires CPR-D-padz). • Monitor the depth of chest compressions during CPR and provide voice prompts, if compression depth is inadequate (requires CPR-D-padz). • Provide a unit cover that functions as a Passive Airway Support System (PASS). (Note the PASS feature is standard with some versions of the product and optional with others.) • Upload data from the defibrillator to a computer to store events or print event reports. • Use commercially available batteries.

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 AED Plus unit. When used with CPR-D-padz, the AED Plus monitors the depth and rate of CPR chest compressions. It provides a CPR metronome function designed to encourage rescuers to perform chest compressions at the AHA/ERC recommended rate of 100-120 compressions per minute (CPM) as well as voice and visual prompts to encourage a compression depth of 5-6 cm for adult victims. WARNING! Real CPR Help is intended for use on adult victims only; do not use on victims under 8 years of age. The adaptive metronome function is disabled during periods when CPR should not be performed (for example, during ECG analyses and defibrillation shock sequences). During periods when CPR may be indicated, the metronome begins issuing audible beeps following detection of the rescuer’s first few compressions. The beeps continue automatically (at rates described below) until a few seconds after chest compressions are halted by the rescuer or until the recommended “CPR period” ends (2 minutes for AHA and ERC protocols). If the rescuer ceases chest compressions during the CPR period, metronome beeps stop within a few seconds after compressions are halted. Audible beeps resume during the CPR period following any re-initiation of CPR compressions. If no CPR compressions are detected during “CPR periods”, the AED Plus periodically re-issues the CONTINUE CPR prompt. The rate of beeps issued by the AED Plus adaptive metronome function adapts to the rescuer’s actual chest compression rate. The metronome will beep at 100 CPM when chest compressions are delivered at greater than 80 compressions per minute (CPM). Should the rescuer fail to deliver compressions at 80 CPM or greater, the metronome will beep at a rate that is approximately 15 CPM higher than the rescuer’s actual rate. This increased metronome rate is intended to encourage the rescuer to increase his/her chest compression rate until the recommended 100 CPM rate is achieved. The metronome beeps at a minimum rate of 60 CPM in cases where the rescuer’s compression rate is substantially below 60 CPM. During CPR, the AED Plus may issue one or more audible prompts based on the depth of chest compressions detected. When Real CPR Help determines that compression depth is consistently less than 5 cm, a PUSH HARDER prompt will be issued. A GOOD COMPRESSION prompt will be issued if the rescuer responds by increasing compression depth to 5 cm or more. The AED Plus unit can be configured to display the FULLY RELEASE text prompt to remind the user to lift the hands off the chest during CPR. By default, this text prompt is not enabled.

ZOLL AED PLUS Administrator’s Guide

Using the AED Plus Graphical User Interface The AED Plus graphical user interface (see Figure 2) is visible on the top of the unit when the cover is removed. The pictograms are reminders of the steps to follow when performing a rescue and reinforce instructions provided through voice prompts and optional display messages. Each pictogram on the device is associated with an indicator light (LED) and voice prompts. This combination draws attention to the graphics in a sequence defined by current protocols for use of an Automated External Defibrillator (AED) by the AHA and ERC.

Figure 2: Graphical User Interface The AED Plus unit contains an LCD display (some special models do not have an LCD) that displays elapsed time, number of shocks delivered, text messages corresponding to the voice prompts, and depth of CPR compressions. The LCD can also be configured to display the acquired ECG signals. When the AED Plus is turned on, the unit automatically initiates the sequence of voice prompts and graphic illuminations for a rescue event. The sequence continues until the AED Plus is turned off or the electrodes are disconnected from the victim for an extended period of time. As soon as electrodes are attached to the victim and impedance of the connection is verified, the unit stops cycling through the above-mentioned voice and graphic illumination sequence and automatically begins analysis of the ECG rhythm. Following the results of this ECG analysis, voice prompts tell the rescuer whether a shockable or non-shockable rhythm has been detected. If a shockable ECG rhythm is present, the graphics illuminate and voice prompts guide the rescuer through the defibrillation sequence. When no shock is advised, the AED Plus issues the audio prompts, NO SHOCK ADVISED and START CPR, and illuminates the CPR-related graphics. A period of 2 minutes (depending upon device configuration) is then allowed for rescuer CPR. Following this “CPR period”, the AED Plus automatically re-initiates a new ECG rhythm analysis.

ZOLL AED PLUS Administrator’s Guide

The AED Plus automatically adjusts defibrillation energy to adult or pediatric levels based on the type of electrodes attached to the unit. In its factory default configuration, the unit delivers the first three shocks at 120J, 150J, and 200J respectively in adult mode, and at 50J, 70J, and 85J in pediatric mode. However, the device can be configured to deliver shocks at other energy levels, as long as the setting for each successive shock is the same or greater than the setting for the preceding shock. Shocks are delivered by depressing the Shock Button (indicated by the heart icon and associated LED) located in the center of the graphical user interface. Consult the AED Plus Operator’s Guide for more details on the graphics included in the unit’s graphic interface, the audio prompts issued at each step in the treatment protocol and the rescuer action associated with these audio and visual prompts. Loss of contact between the electrodes and the victim interrupts ECG analysis and/or shock delivery until the electrodes are re-attached and results in a CHECK ELECTRODE PADS prompt to the operator.

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. If the victim requires airway support and there is no evidence of head or neck trauma, roll the victim on his/her side and then roll him/her back over so that the PASS is under the victim’s shoulders causing the head to tilt backwards. For PASS COVERS only: The shape of the PASS, when placed under the shoulders of the victim, can be used to help maintain an open airway (see Figure 4).

The unit cover also functions as the Passive Airway Support System (PASS).

Place the PASS under the victim to lift his/her shoulders. Do not use the PASS if there is a suspected head or neck injury.
