1 Introduction to the DDU-120 Series AED This User Manual provides information to guide trained operators in the use and maintenance of the Defibtech DDU-120 series Fully Automatic External Defibrillator (“AED”) and its accessories. This chapter includes an overview of the AED, a discussion of when it should and should not be used, and information on required operator training.
1.1
Overview
The DDU-120 AED is a Fully Automatic External Defibrillator (“AED”) that is designed to be easy to use, portable and battery powered. It has only one user control: the ON/OFF button. Voice prompts and visual indicators provide a simple interface for the operator. The DDU-120 AED is capable of recording event information including ECG, audio data (optional), and SHOCK/NO-SHOCK recommendations. When connected to a patient who is unconscious and not breathing, the DDU-120 AED performs the following tasks: • • • • •
Prompts the operator to take necessary actions to enable analysis. Automatically analyzes the patient’s ECG. Determines whether a shockable rhythm is present. Charges the defibrillation capacitor. Automatically (without user intervention) delivers a shock once the device has determined a shock is required. • Prompts the user to administer CPR if needed. The DDU-120 AED will shock the patient automatically, without additional interaction by the user, if a shock is required. The DDU-120 AED uses two self-adhesive defibrillation/monitoring pads to monitor ECG signals and, if necessary, to deliver defibrillation energy to the patient. These pads (also known as electrodes) are provided in a single-use, disposable package. The DDU-120 AED determines proper pad-to-patient contact by monitoring the impedance between the two pads (impedance varies with the electrical resistance of the patient’s body). Visual and audio prompts inform the operator of possible problems with patient contact. Voice prompts and visual indicators communicate the status of the AED and of the patient to the operator. The DDU-120 AED has one push-button control and several LED indicators. Defibrillation energy is delivered as an impedance compensated biphasic truncated exponential waveform. The device delivers 150 Joules into a 50-ohm load when using adult pads or when using
DAC-530-EN-AC
attenuated child / infant pads, 50J of defibrillation energy into a 50-ohm load. Energy delivered does not change significantly with patient impedance, although the duration of the generated waveform will vary. The Defibtech AED is designed to deliver up to 150J of defibrillation energy through a patient impedance range of 25 – 180 ohms or 50J of defibrillation energy when using the child / infant pads. Defibrillation and AED operating power is supplied by a replaceable (non-rechargeable) lithium battery pack that provides for long standby life and low maintenance operation. Battery packs are available in several configurations optimized for use in specific applications. Each pack is marked with an expiration date. The DDU-120 AED records event documentation internally and, optionally, on Defibtech Data Cards (“DDC”). The optional DDC plugs into a slot in the AED and enables the AED to record event documentation, and audio (audio enabled cards only) if sufficient space is available on the card. Audio recording is available only for units with installed audio-enabled Defibtech Data Cards. Event documentation stored internally can be downloaded onto a DDC for review.

WARNING
CAUTION
WARNING
2.2.3 Patient Analysis
Aggressive or prolonged CPR to a patient with defibrillation pads attached can cause damage to the pads. Replace the defibrillation pads if they become damaged during use.
CPR rates above the American Heart Association guidelines of 100 BPM (beats per minute) can cause incorrect or delayed diagnosis by the patient analysis system.
Do not place adult defibrillation pads in the anterior-posterior (front-back) position. A shock or no shock decision may be inappropriately advised. The DDU-120 AED requires that the adult defibrillation pads be placed in the anterioranterior (front-front) position.
Some very low amplitude or low frequency rhythms may not be interpreted as shockable VF rhythms. Also some VT rhythms may not be interpreted as shockable rhythms.
Handling or transporting the patient during ECG analysis can cause incorrect or delayed diagnosis, especially if very low amplitude or low frequency rhythms are present. During analysis and from “Shock Advised” until “Shock Delivered,” patient movement and vibration must be minimized.

3.2
Installing the Data Card The Defibtech Data Card (“DDC”) is used to store event and audio information collected by the AED. All DDU-120 AEDs will operate without DDCs and will still store critical event information internally. Different DDC versions store different amounts of information. DDCs are available in versions that store and don’t store audio information. Refer to the DDC technical specification for exact storage capabilities. DDCs may be reviewed with a separate PC based software package - see “Event Viewing” section.
To install the DDC, remove the battery pack and push the DDC, label side up, into the thin slot in the side of the AED centered over the battery pack opening. The card should click into place and be flush with the surface of the slot. If the card does not push in all the way, it may have been inserted upside down. In that case, remove the card, flip it over and try inserting it again. To remove the DDC, press the card in all the way and then let go. The DDC will be partially ejected and can be removed by pulling it the rest of the way out.
3.3
Installing the Active Status Indicator 9V Battery
A user-replaceable lithium 9V battery, located inside the battery pack, provides Active Status Indicator (“ASI”) power. This auxiliary battery is used to provide standby indicator power independently of the main lithium battery (contained in the battery pack) allowing the main battery pack to have a significantly longer shelf and standby life. The unit will operate without a 9V battery installed in the battery pack, but active status indication will not be provided. If no 9V battery is installed, status can still be checked by turning the unit on. Only a fresh 9V lithium battery should be used as a replacement. Refer to the Maintenance section for more information on replacement batteries.
12 DAC-530-EN-AC
The 9V battery is installed into the battery pack in the 9V battery compartment. To install, remove the cover covering the 9V battery compartment by pushing on it sideways. The cover will slide and detach from the battery pack. Insert the 9V battery into the 9V battery compartment so that the contacts on the battery touch the contacts in the battery pack. The orientation of the battery contacts is shown in a picture on the inside bottom of the 9V battery compartment. Replace the 9V battery compartment door by placing it in the almost closed position and then sliding it closed.
