ZOLL AED PLUS Administrator’s Guide

Using the ZOLL AED Plus Graphical User Interface
The ZOLL 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
AED by the American Heart Association (AHA) and the European Resuscitation Council (ERC).
Figure 2: Graphical User Interface
The ZOLL 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 device is turned on, the unit automatically initiates the sequence of voice prompts and
graphic illuminations for a rescue event. The sequence continues until the device is turned off or the
electrodes are disconnected from the patient for an extended period of time. As soon as electrodes are
attached to the patient 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 ZOLL 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 ZOLL AED Plus automatically re-
initiates a new ECG rhythm analysis.
