I check our village AED periodically to ensure that it is in working order, the battery is good, pads are in date and all of the necessary equipment is there in case it is ever needed.
So far to date Yorkshire Ambulance Service have sent someone for it on 6 separate occasions, though thankfully has never been needed to defibrillate a patient.
The battery and defibrillator pads do expire however, as the battery starts to run flat and the pads become less effective as the gel used in them starts to degrade.
I set up a go fund me page to initially raise funds to purchase the AED, however managed to get it and all of the other equipment free of charge.
We still need to raise funds for when the battery and pads need to be replaced.
I personally hope you waste your money and the village defibrillator is never used, however please donate so we can keep this lifesaving equipment in working order and available should the need ever arise.
