3 Setting up the DDU-120 AED This chapter describes the steps required to make your Defibtech DDU-120 AED operational. The DDU-120 AED is designed to be stored in a “ready” state. This chapter tells you how to make the device ready, so that if and when you need it, few steps are required to begin using the device.
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.
If the battery pack is stored outside the unit for an extended period of time, removal of the 9V battery will extend the 9V battery’s life. Note that in an emergency situation, the battery pack may be used without a 9V battery. If needed, a non-lithium based 9V battery may also be used, but standby status indication life will be reduced.
Within moments of insertion (if a non-discharged 9V ASI battery is installed) the DDU-120 will turn on and run a battery pack insertion self-test. The unit will automatically shut off after the test is run. Afterwards, the Active Status Indicator on the top corner of the DDU-120 AED will periodically flash (if a nondischarged 9V ASI battery was previously installed in the battery pack).
The Active Status Indicator should periodically blink with a green light. If it blinks with a red light or does not blink at all, the DDU-120 AED needs servicing – refer to the “Checking Active Status Indicator” section for more information. Defibtech recommends storing your AED in an easily accessible location. DAC-530E-EN-BH...
4 Using the DDU-120 AED This chapter describes how to use the DDU-120 AED. The DDU-120 AED was designed for simple operation, allowing the operator to focus on the patient. It has only one user control: the ON/OFF button. It also has four light emitting diode (LED) indicators. Concise and easily understandable voice messages and prompts guide the operator through the use of the unit.
4.2 Checking DDU-120 AED Status Once a fully functional battery pack with a non-discharged 9V battery is installed in the DDU-120 AED, an LED indicator located in the corner of the unit actively indicates unit status. If the unit is fully operational, the Active Status Indicator (“ASI”) will blink green and if the unit needs attention, the ASI will blink red.
This reduces the time needed to setup and start treatment in an emergency. The Defibtech AED should be stored with the pad connector plugged into the unit. However, if pads were damaged or not properly connected, you may need to substitute a new set of pads during an emergency.
If not needed for immediate use, the pad package can then be stored in the pad storage slot in the back of the DDU-120 AED. After connecting the pads connector to the unit, push the pad package, with the pictures on the package facing up and out, rounded end first, into the pad holder compartment on the back of the AED.
4.4.6 Follow DDU-120 AED Prompts At this point, the DDU-120 AED will check to make sure that the pads are well connected to the patient and that an adequate ECG signal is being received. Do not touch the patient, eliminate any patient movement, and cease CPR at this time.
not sticking due to excessive hair, shave or clip excessive chest hair. If the prompts continue, try replacing the pads with a new set. The “check pads” LED will flash red during this message. “Replace pads” – This indicates that the pads are not making proper contact with the patient and that the impedance is out of range for proper ECG analysis and shock delivery.
Analysis related voice prompts: “Analyzing heart rhythm” – This indicates that the DDU-120 AED is actively analyzing the patient’s ECG signal. The AED will continue analyzing until it has determined whether a rhythm is shockable or non-shockable or analyzing is interrupted for some reason. The “analyzing” LED will flash green during this period.
Page 32
Shock related voice prompts: “Charging” – This indicates that the DDU-120 AED has determined that a shock is recommended and is charging the unit in anticipation of a defibrillation shock. Analysis will continue during this phase and the “analyzing” LED will continue to flash green. A tone will sound to indicate charging progress. If the unit detects a rhythm change to a non-shockable one, charging will abort and the user will be prompted to begin CPR, if needed, for a period of two minutes.
4.7 No Shock Required If the DDU-120 AED ECG analysis algorithm has determined that a shock is not required, the operator will be prompted to begin CPR, if needed, for a period of two minutes. The unit will not be monitoring the patient’s ECG rhythm during this two minute CPR period.
“Stop now, ” “Do not touch the patient” – This indicates that the two-minute CPR period has ended and the user should stop CPR. The unit will enter Analyzing mode and the “analyzing” LED will flash. 4.8 Post-Shock CPR If the AED has delivered a shock, the unit will require a mandatory two-minute CPR period.
• Check to make sure that the Active Status Indicator is flashing green. 4.10 Operational Environment The Defibtech AED is designed to operate in a wide range of environmental conditions. To ensure the reliability and safety of the AED in a given environment, refer to the “Environmental” section for a detailed list of approved environmental conditions.
5 Maintaining and Troubleshooting the DDU-120 AED This chapter describes the maintenance and troubleshooting procedures for the DDU-120 AED. The Self-Tests that are performed by the device are described along with the frequency and nature of periodic maintenance for which the owner/operator is responsible. A troubleshooting guide is provided to help diagnose user serviceable problems.
5.2.1 Checking Active Status Indicator The Active Status Indicator (“ASI”) is located in the upper corner of the DDU-120 AED and indicates the operational readiness state of the unit. It will periodically flash green to indicate a fully functional condition. If it is flashing red or not flashing at all, the AED needs attention. Anytime the ASI is flashing red and a good 9V battery is installed, the unit will periodically emit a “beep”...
5.2.4 Replacing Pads The Defibtech defibrillation/monitoring pads are intended for one time use only. The pads must be replaced after each use or if the package has been damaged. The DDU-120 AED defibrillation/monitoring pads are supplied in a sealed pouch with the connector and part of the cable exposed.
First, check to ensure that the pad package has not expired. Pads past their expiration date should not be used and should be discarded. Next, check to ensure that the pads package has not been torn, opened or damaged. Dispose of the pads if the package is open or damaged. Inspect the pads cable and replace if any nicks, cuts, or broken cables are found.
To remove the DDC card, press the DDC in all the way and then release. The DDC will be partially ejected and can be removed by pulling it the rest of the way out. To install a new DDC, insert the DDC, label side up, in the thin slot on the top of the opening for the battery pack.
