AEDs Questions & Answers

AED’s include status indicators that allow you to determine, visually, whether your AED is functioning properly. The AED will run an automatic self-check and will display a light or check mark to signify that it has passed its self-check. If the self-check does not pass, the AED will alert you with a chirp.
This answer depends on the brand of AED you choose, though every 4 years on standby if the battery is installed by the “Install by” date. Some defibrillators can give multiple shocks on one battery charge, so it is not necessary to replace the battery after each use on these models. If your AED is chirping, it could be because the battery is low, in which case the machine will inform you.
You will need to replace the pads each time you use them (they cannot be reused) or when they reach their expiration date. You should also check the electrolytic gel on the pads when the AED chirps to ensure the gel has not dried out over time. Most brands should be replaced every two to four years.
Electrode pads are not interchangeable. Each manufacturer has their own proprietary means of attaching AED electrode pads to their AED devices. Purchase only manufacturer-approved electrode pads designed for your make and model AED.
If possible, infants and children should use the pediatric electrode pads; however, if they are not available, it is possible to place the pads on the front and back of children to keep the pads from touching during administration.
AED’s should never be placed in a locked cabinet and should be easily-accessible and highly visible. It is important to get the AED to the patient as quickly as possible, preferably within 1 ½ - 2 minutes.
Anyone, including children, who can follow the directions (visual and vocal prompts) on the machine can operate it. Using the AED requires no strength or stamina, though CPR does, if required in the situation. Although it is not always necessary to be trained to use an AED, we strongly suggest it.
Your staff should be re-trained every two years, but preferably yearly, to comply with the American Heart, Red Cross, and most other training organizations. During all staff meetings, the emergency plans should be discussed, noting where the AED is placed and who is certified to use it.
The AED will prompt the rescuer if and when to begin CPR and, depending on the make and model of the AED, will provide a metronome or beeps to keep you on track for the rate of compressions. Some AEDs can provide real-time feedback on the rate and/or depth of compressions, as well. The AED will also prompt when to stop compressions for analysis and shock, if necessary.
Not every cardiac arrest is caused by ventricular fibrillation (the fatal rhythm that causes sudden cardiac arrest). Approximately one third of the time the heart will not be in VF and the AED will not deliver a shock, but will advise the rescuer to check the patient and begin CPR.
You should always place the pads as close as possible to where it is shown in the diagram. When the pads are in an incorrect location, the shock is less effective.
If the patient is wearing a bra, lift the bra up over the breasts, letting it bunch up around the neck, and then attach the pads. If the patient’s chest is hairy and the pads won’t stick, a disposable razor can be used to shave the necessary locations to place the pads. It is therefore advisable to keep a disposable shaver with the AED for just this purpose.
Defibrillation is most safely performed on a dry surface with dry skin. Try to dry the patient’s chest before applying the pads. If it is not possible to move the patient to a dry surface, bystanders and anyone not necessary to operate the AED should be moved away to a dry surface and rescuers should avoid direct contact with the patient. Wearing latex gloves will reduce the risk of the rescuer being shocked if the rescuer is touching the patient during defibrillation.
Unfortunately, no. Many factors can affect the outcome of the situation, including the timing of help, the heart’s rhythm, and the underlying reason that caused the patient to go into cardiac arrest. However, you will have the possibility to give the patient another chance - one they wouldn’t have had had there not been access to an AED machine.
