Introduction To The DDU-2000 Series AED
This User Manual provides information to guide 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 an Automated External Defibrillator that is designed to be easy to use, portable, and
battery powered. Push-button controls include an ON/OFF button and three softkey buttons. Semi-automatic DDU-
2300, DDU-2450, and DDU-2475 AEDs have a SHOCK button; fully-automatic DDU-2200 AEDs have a SHOCK
Required Indicator LED. 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-2200
— This unit is a
fully-automatic external defibrillator
. It
WILL
shock a patient automatically
without additional interaction by the operator if a shock is required. Operates in AED Mode.
•
DDU-2300, DDU-2450, and DDU-2475
— These units are all
semi-automatic external defibrillators
. They
will
NOT
shock a patient automatically; they will only advise. 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. Operational characteristics of these models are as follows:
DDU-2300
— Operates in AED Mode.
DDU-2450
— Operates in AED Mode; includes patient ECG display.
DDU-2475
— Equivalent to the DDU-2450; configurable
to include additional features (contact Defibtech
or your distributor for details).*
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.
•
DDU-2300 and DDU-2450:
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.
•
DDU-2200:
Automatically delivers a shock, without any user intervention, once the device has determined 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, semi-automatic AEDs will
NOT
shock a patient automatically; they 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. The fully-automatic DDU-2200 AED
WILL
shock a patient automatically
without additional interaction by the user if a shock is required.
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.
