Recommended User Action
• Remove and reinsert PADS connector into the universal cable.
• Check for damaged defibrillator pads, wires and or connector.
• Check for dried out or expired defibrillator pads.
• Clip (not shave) the patient's hair and wipe pad contact area dry.
• Connect the cable to the test plug. The DEFIB PAD SHORT
message displays to indicate that the cable is functioning properly.
• If the DEFIB PAD SHORT message displays, then check the
connections of the pads to the patient and to the defibrillator cable.
• If the DEFIB PAD SHORT message does not display, remove the
defibrillator from service.
• Avoiding using alcohol and betadine in and around the treatment
area because these skin preparations may lead to increased
conductivity and/or bonding between the electrode's adhesive and
skin.
• Check for gel droop. If the gel has leaked out of the gel treatment
area, replace the electrode.
• Ensure pads are coupling to the patient's skin and connected to the
universal cable.
• Check for dried out gel on the defibrillator pad.
• Clip patient's excessive hair. Do not shave hair.
• Check expiration date. Replace pad if date has expired.
• Do not conduct chest compression through the pads because the
pads could be damaged leading to the possibility of arcing and skin
burns.
• Apply the back electrode first. If the front electrode is already in
place when the patient is being maneuvered for placement on the
back, the front may become partially lifted, possibly causing arching
and skin burns.
Verify heart rate flashes with each QRS on display.
• Change lead selection.
• Change ECG size.
• Reposition ECG electrodes.
