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.
If there is a problem with the pad connection, connector connection, patient motion or other interference,
the AED will guide the operator with audible and visual prompts. Visual prompts consisting of flashing
LEDs with associated labeling reinforce the audio prompts and aid in high ambient noise environments.
Pad related voice prompts:
“Plug in pads connector” – This indicates that the DDU-120 AED has determined that the pads
are not properly connected to the unit. Check that the connector is fully inserted into the unit. If the
prompts continue, try removing and reinserting the pads connector or try a new set of pads. The
“check pads” LED will flash red during this message.
“Remove clothing from patient’s chest” – This instructs the user to remove all clothing from
the patient’s chest. Pads must be applied to the patient’s bare chest.
“Locate pads package in back of AED” – This helps the user locate the pads in the pad
storage area, which is located in the back of the unit.
“Tear open pads package” – This instructs the user to tear open the pads package on the dotted
line on top of the package. Once the package is open, the user will be able to remove the pads from
inside the package.
“Peel pads from blue liner” – This instructs the user to peel each pad from the blue liner before
placing the pads on the patient. Peel the pads from the blue liner only when the pad is ready to be
placed. Place the pads with the sticky side of the pad on the patient’s bare skin.
“Apply pads to patient’s bare chest as shown” – This indicates that the DDU-120 AED
has determined that the pads are not placed on the patient. Place pads on the patient following
instructions on the pad package. If the prompts continue, try replacing the pads with a new set. The
“check pads” LED will flash red during this message.
“Plug in and apply pads” – This indicates that the DDU-120 AED has determined that the pads
are not plugged in and not applied to the patient. Check that the connector is fully inserted into the
unit. If the prompts continue, try removing and reinserting the pads connector or try a new set of
pads. The “check pads” LED will flash red during this message.
“Poor pad contact to patient,” “Press pads firmly” – 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. Check that the pads are properly placed and fully adhering to the patient
and that there are no air bubbles between the pads and the patient. Make sure that the pads are
not touching each other. If the pads are not sticking due to moisture, dry the patient. If the pads are
