Lesson video

In progress...


Hello, and welcome to your fourth and final lesson in the first aid unit on defibrillators, AEDs.

I'm Mr. Clarke, and I'm your teacher for today and I've really enjoyed exploring and learning life-saving skills together over the past few lessons.

From those first steps on assessing a casualty to learning how to do the recovery position and performing CPR.

So, although it's our final lesson together I'm still really excited to get going and continue our first aid learning journey.

Are you ready too? Well, let's get started then.

To be able to fully participate in today's lesson, you are going to need the following, an exercise book or piece of paper and a pen.

If you need to go and quickly find that before we start just pause the video now and press play when you're ready to begin.

Now, you've already started your learning journey for this lesson because you should have completed the intro quiz.

And I look forward to checking those results very soon.

During the rest of today's lesson we'll be looking at how we find AEDs, understanding how they actually work, and how we use them.

This will then give you the knowledge you need to go and complete your final exit quiz of the unit.

This lesson today brings us some more key words to explore.

So you might like to write these down because they are going to be used through out today's lesson.

The first one of course is going to be AED, which stands for automated external defibrillator.

And that is a name given to a portable electronic machine that can detect the abnormal heart rhythms that are present when someone has a cardiac arrest.

Now, I'm sure you know lots about heart beats and heart rhythms for your PE or science lessons.

And I'm sure some of you have even felt what your normal heart rate feels like.

When somebody doesn't have that normal heart rate it's called an abnormal heart rate.

And that's when we might need an AED.

Now, we've seen the word cardiac arrest before in the last lesson but just to remind you cardiac arrest is what we say When the heart has stopped.

Over this unit we have explored so much and covered a number of key words.

How many of them can you remember though? In a moment I want you to draw yourself a mind map, just like I have.

I want you to write down all the key words that you can remember.

I didn't do it throughout the lesson as well.

At the very end, we'll go back and we'll compare our mind maps, and to help you I've started mine already.

On mine I've put AED and cardiac arrest.

So pause this video now and complete the task.

And then when you're ready to resume your learning just press play again.

I've got a question.

Do you know where you can find AEDs? Pause this video and write down the locations you think out of the ones below we might find an AED.

And when you feel you're ready to answer you can press play again.

So, pause this video now.

Welcome back.

Can you point to locations that you think are correct.

I'm not sure if they're all correct or maybe one or two are correct.

Who knows, let's see.

Pointing out the answer you think in three, two, one.


Well, should I let you into a little bit of a secret? They're all correct.

You can find AEDs in public places, such as offices, schools, gyms, shopping centres, supermarket, stations, airports, the list goes on, and you can even find them when you're on holiday as well.

You just need to look out for an AED signage which you can see on those machines there.

And if you can't find one, well, when you ring 999 they'll be able to tell you where you can find one.

In some places though, AEDs are kept in an unlocked cabinets.

So anybody can access them.

Sometimes though, like we see in the phone box the cabinet might be locked.

So when you phone up 999, the emergency service operator will give you a code over the phone which will then allow you to unlock it.

If possible though, and this is really important.

One person should perform CPR, which we covered in what lesson? One, two, or three.

What lesson was it? Can you remember? In lesson three.

While another person goes and finds an AED? How AEDs work is that when an abnormal rhythm is detected the machine delivers an electric charge, that shock that might be able to restart the heart or establish a regular rhythm.

The sooner the heart is restarted then the better the casualty chances of survival is, because it can take time for an ambulance to arrive.

So, using an AED could save a life.

And that's the important thing to remember.

Do you know if true or false that you can only use an AED if you are medically trained to do so? Is that true or is that false? Point to what you think is the correct answer.

In three, you're ready? Two, one.

What'd you think? Should we say the correct answer? It's false.

You must remember that you don't need to be a medical professional or first aider.

The machine will speak the instructions for you.

And it quite literally guides you through the whole process.

Let's recap some things to remember when using an AED.

The first one, you cannot harm the casualty because it will only work when it detects an irregular heart rhythm.

Some people are really worried about using one in case it's not the right time.

Don't worry about it.

The machine knows when it's the right time.

If possible one person should perform CPR while another finds an AED.

Every second or minute that goes by means the casualty's life is on the line.

So the quicker we can start the process performing CPR and slash or AED the better.

And finally, you are always better off using an AED if someone is having a cardiac arrest than doing nothing.

The whole purpose of first aid is to save life.

Okay then.

How are you doing with your mind map that we started at the very start of today's lesson? Pause this video now and go back to it and see if you can think of any more words to add to it.

When you're ready to start again, just press play.

How did you do? Should we compare? if I put down any words that you don't have don't forget to add them yourself.

I put AED, unconscious, and CPR.

And I guess I also could have put the opposite of unconscious, which is conscious.

I also put airways, first aid, and circulation.

Then I added cardiac arrest and respiratory arrest and recovery position.

Did you have anything extra that you put on yours? If you're not sure what some of these words mean as well or you've forgotten, then you don't have to worry because you can go back and look at the other lessons again.

Wow, how have we finished this unit already! You have been amazing and we've worked super hard over the past few lessons.

So you should feel really proud of yourself.

Well done.

Don't forget that you still got your final exit quiz to complete and perhaps after all this, you might want to go and create a poster or a leaflet with first aid tips and information to help others learn about it too.

Knowing what to do in an emergency situation and how to administer first aid is truly a life saving skill which now you have.

And that's pretty cool.

As I said, you can always come back to watch any of the lessons to refresh yourself on the skills or to remember the key words.

Or perhaps now you're ready to move on and look at one of the other amazing RSAT topics on Oak Academy.

I hope to see you all soon, goodbye.
