What we're going to do now is have a look at actually using an AED. Now, we're in a training room scenario here so we're using the manikins, and in a real scenario we work the same but you'd work much quicker. Honestly, I'm breaking this down into individual stages just to make it easier and know exactly what you're doing. The first thing we're going to assume, we'll assume we've already walked into the room, we found the person on the floor, we've done the scene safety and obviously, I've got my gloves on. The initial stages we would've been done already. We'd have already introduced ourselves trying to get a reaction out of them, open the airway, found out they're not breathing, and continuing CPR. This is the moment we're taking on from when the AED arrives. So, the first thing we need to do is we need to put the pads on to bare skin. The first thing we do here is literally take off clothing just to expose the chest. The reason we do this is that we need to put the pads on to bare skin. Now, we would need to take off any clothing that's there, including bras or any underwear that's on there as well because we must make sure we get contact with clean skin and there's nothing going to be in the way.

We're also going to have a visual inspection around to make sure maybe with even at this stage see that there's a pacemaker inserted, which you'd see under the skin here, maybe look for other scarring, which might indicate that the person could've had some heart surgery, something like that. We're also looking for any obvious patches and jewellery. Now, some of the patches have metal in them, and this can in some cases because of a problem. But if not jewellery, if they're wearing a necklace you just pull out the wire and take it off, because we don't want the electricity to be transferred through the necklace and not through the heart.

So, we're checking the entire area is clear. Now, in the real world of doing this, especially if there's two of you, one could get the AED ready and the other one could carry on the CPR. It's crucial that we keep the CPR cycle going the whole time. Now, remember, the quicker we get this AED unit on the better. Every minute the chance of survival drops 10%, so if you can get on within four minutes, this person's chance of survival is much better than maybe eight minutes or more when the ambulance turned up.

The unit tells you that as well. So, it's giving you lots of help with your CPR, whether you're doing fast, going too fast, you're going to deep, the actual unit is telling you that that's the case. So, it's a very good way of giving you real-time CPR help. This is perfect if someone hasn't got that much experience. In this example here, we're looking at complete low experience scenario: We got somebody just turned up, the AED unit's there, they're doing continued chest compressions, they've activated the emergency services, all the things they have to do, but the unit is guiding them through. It's guiding them through their CPR, if they're not good enough, they need to do more, then that's fine. So, these units are extremely simple and they're just perfect for anybody who needs that extra CPR help
