1 Introduction To The DDU-2000 Series AED
This User Manual provides information to guide trained operators in the use and maintenance of the Defibtech
DDU-2000 Series Automated External Defibrillator (AED) and its accessories. It includes comprehensive training
on set-up, use, and maintenance and is the source for complete technical specifications.
This chapter includes intended use, an overview of the AED, a discussion of when it should and should not be used,
and information on operator training.
1.1 Overview
The DDU-2000 Series AED is a Semi-Automatic External Defibrillator that is designed to be easy to use, portable,
and battery powered. Push-button controls include an ON/OFF button, three softkey buttons, and a SHOCK button.
Voice prompts, text prompts, and a display screen with visual prompts provide a simple interface for the operator.
The DDU-2000 Series AED is capable of recording event information, including ECG, audio data (optional), and
SHOCK/NO-SHOCK recommendations.
The DDU-2000 Series of AEDs includes the following models:
• DDU-2300 — Operates in AED Mode.
• DDU-2450 — Operates in AED Mode; includes patient ECG display and ECG monitor mode using an
optional ECG Monitoring Adapter.
In AED Mode, the DDU-2000 Series AED performs the following tasks:
• Prompts the operator, through audio, text, and video prompts, to prepare the patient for treatment.
• Automatically analyzes the patient’s ECG.
• Determines whether a shockable rhythm is present.
• Charges the capacitor.
• Arms the SHOCK button if the AED detects a shockable rhythm and prompts the operator to press the
SHOCK button when the device is ready and a shock is advised.
• Provides instructions to perform CPR.
• Repeats the process, if needed.
• Allows user to select between Video display or ECG display (DDU-2450 only).
In AED Mode, the DDU-2000 Series AED will NOT shock a patient automatically; it will only advise the operator.
The SHOCK button is enabled only when a shockable rhythm is detected and the device is charged and ready to
shock. Charging occurs automatically when the device detects a shockable rhythm. The operator must press the
SHOCK button to initiate defibrillation.
In ECG Monitor Mode (DDU-2450 only), the AED allows display of the patient ECG using an optional 3-wire
(LEAD II) ECG adapter cable. ECG Monitor Mode provides a non-diagnostic display of the heart rhythm of a responsive
or breathing patient for attended patient monitoring. While connected to the ECG adapter cable, the AED disables
its shock capability.
The DDU-2000 Series AED uses two self-adhesive, single-use, non-sterile defibrillation pads (also known as electrode
pads or pads) to monitor ECG signals and, if advised, to deliver defibrillation energy to the patient. These pads are
provided in a single-use, disposable package that can be preconnected to the AED. The pads package is labeled with
an expiration date. The DDU-2000 Series AED determines proper pad-to-patient contact by measuring the impedance
between the two pads.
The DDU-2000 Series AED user interface is clear and concise. It has push-button controls and a display screen. Easily
understandable voice messages and text and video prompts guide the operator through the use of the unit. The device
communicates the status of the AED and of the patient to the operator.
Defibrillation energy is delivered as an impedance compensated biphasic truncated exponential waveform. In AED
Mode, the device delivers 150 Joules of defibrillation energy (into a 50-ohm load) when using adult defibrillation
pads and 50 J of defibrillation energy (into a 50-ohm load) when using child/infant pads (also known as pediatric
defibrillation pads). Energy delivered does not change significantly with patient impedance, although the duration of
the generated waveform will vary.
