0:00:23 > 0:00:25He's Dr Chris.
0:00:25 > 0:00:26He's Dr Xand.
0:00:26 > 0:00:28And yes, we're identical twins!
0:00:29 > 0:00:34Do you know your body does heaps of amazing things every single day?
0:00:34 > 0:00:35That is incredible.
0:00:35 > 0:00:37And we're going to show you how.
0:00:37 > 0:00:39Ah! You've cut him in half.
0:00:39 > 0:00:41We've got incredible experiments
0:00:41 > 0:00:43- Ah!- BOTH: Wow.
0:00:43 > 0:00:45And real-life medical emergencies.
0:00:45 > 0:00:48- There's a big chunk of my leg missing.- Ouch!
0:00:48 > 0:00:51We'll be turning our bodies inside out...
0:00:51 > 0:00:53Oh, yuck!
0:00:53 > 0:00:55..to show you what you're made of.
0:00:55 > 0:00:57HE BREAKS WIND You should see a doctor.
0:00:57 > 0:00:59I'd better go find one.
0:00:59 > 0:01:01HE CLEARS HIS THROAT
0:01:01 > 0:01:03Dr Xand, hmm?
0:01:06 > 0:01:08Coming up today...
0:01:08 > 0:01:09On Operation Ouch!
0:01:09 > 0:01:11What are you doing in there?
0:01:13 > 0:01:16We find out what makes your ticker tick.
0:01:16 > 0:01:19This is a real heart.
0:01:19 > 0:01:23I'm on the road with the West Midlands Ambulance Service.
0:01:23 > 0:01:26We're driving toward the emergency and the call is still going on.
0:01:26 > 0:01:29And we show you what to do if this happens.
0:01:29 > 0:01:31I think I've broken my arm.
0:01:31 > 0:01:32But first...
0:01:34 > 0:01:36..we're giving you exclusive access to
0:01:36 > 0:01:38an Accident and Emergency department.
0:01:38 > 0:01:42- Well, come on. Let's meet the first patient!- All right, all right.
0:01:42 > 0:01:44At the Royal Manchester Children's Hospital,
0:01:44 > 0:01:47seven-year-old Logan has come in with his mum
0:01:47 > 0:01:49and a rather unique ailment.
0:01:49 > 0:01:52Whoa, what's happened to your cheek?
0:01:52 > 0:01:54My cheek looks like a hamster cheek.
0:01:55 > 0:01:57So, you're a cheeky little hamster?
0:01:57 > 0:02:00- No, I'm not a hamster. - Are you sure?- No.
0:02:00 > 0:02:04OK, let's find out how he got that swollen cheek.
0:02:04 > 0:02:07- OWL HOOTS - Logan was cosily tucked up in bed
0:02:07 > 0:02:11when a pain in his tooth disturbed his sleep.
0:02:11 > 0:02:13Uh, hello? Who's this little fella?
0:02:13 > 0:02:15Keep up, Xand. It's a hamster.
0:02:15 > 0:02:18Anyway, Logan had taken his nasty gnasher
0:02:18 > 0:02:20to get fixed by a dentist before.
0:02:20 > 0:02:24But the painful problem came back.
0:02:24 > 0:02:26Ooh, nice swag bag, Hammy!
0:02:26 > 0:02:27What? Focus, Xand!
0:02:27 > 0:02:29ZAP! Oh, OK.
0:02:29 > 0:02:33Logan didn't feel like himself, and so woke up his mum.
0:02:33 > 0:02:37Not only did he have a sore tooth, he had a red, swollen face, too.
0:02:37 > 0:02:40Oh, so that's where the hamster comes in? Ouch.
0:02:40 > 0:02:44Someone who does understand Logan's torturous tooth
0:02:44 > 0:02:46is Dr Alex Trott.
0:02:46 > 0:02:47What's been happening, Logan?
0:02:47 > 0:02:49It's been sore
0:02:49 > 0:02:51and it's turned into a hamster cheek.
0:02:51 > 0:02:53Right.
0:02:53 > 0:02:55- I've got a shiner here...- I can see.
0:02:55 > 0:02:57- ..and it's bright pink. - OK.
0:02:57 > 0:03:00And inside I've got a tooth and it's got a big, black hole in it.
0:03:00 > 0:03:01A black hole?
0:03:01 > 0:03:04Well, that's a thorough rundown of your ailments, Logan.
0:03:04 > 0:03:06Can you open your mouth for me?
0:03:06 > 0:03:08I'm just going to have a look with the torch.
0:03:08 > 0:03:11Dr Alex needs to spot exactly where all this pain
0:03:11 > 0:03:15- and swelling is coming from. - And it's sore up there?- Yeah.
0:03:15 > 0:03:17So, what do you reckon, Doc?
0:03:17 > 0:03:21OK. It's a dental abscess, but it's quite a nasty one.
0:03:21 > 0:03:23So, it's one of these top teeth, I think it's his back baby
0:03:23 > 0:03:26- molar tooth and that's where the infection is sitting.- OK.
0:03:26 > 0:03:28OK.
0:03:28 > 0:03:31A dental abscess is a collection of gooey pus that forms in the
0:03:31 > 0:03:36tooth or in the gum and is caused by a bacterial infection.
0:03:36 > 0:03:39First, it's off to X-ray for a proper look.
0:03:39 > 0:03:42Come closer. Your chin on here, you bite on there,
0:03:42 > 0:03:44and we'll be done in a minute.
0:03:44 > 0:03:46Good boy, really still.
0:03:46 > 0:03:48OK, well done.
0:03:48 > 0:03:51That's the problem tooth right there.
0:03:51 > 0:03:54It needs fixing, so we'll catch up with Logan a bit later on
0:03:54 > 0:03:56and find out what happens.
0:04:01 > 0:04:04And now to our lab for some amazing body experiments.
0:04:04 > 0:04:06- Eugh!- Whoa.
0:04:06 > 0:04:09Just don't try anything you see here at home.
0:04:09 > 0:04:12Today it's your body's ticker, the heart.
0:04:12 > 0:04:14Xand is having a little lie down.
0:04:14 > 0:04:17You could actually try this bit at home. It's quite nice.
0:04:17 > 0:04:20But what you can't try at home is hooking Xand up
0:04:20 > 0:04:23to an electrocardiogram, which is what I've done,
0:04:23 > 0:04:25and it's basically a heart monitor.
0:04:25 > 0:04:28And each one of these spikes on the display is a separate
0:04:28 > 0:04:31beat of the heart. And it doesn't matter what you're doing, even if
0:04:31 > 0:04:33you're just lazing around like Xand,
0:04:33 > 0:04:35- your heart never stops beating. - XAND SNORES
0:04:35 > 0:04:38It beats even when you're asleep,
0:04:38 > 0:04:40as Xand seems to be illustrating perfectly.
0:04:40 > 0:04:44You can see the spikes and his pulse is around 70.
0:04:44 > 0:04:46OK, Xand, demonstration over.
0:04:46 > 0:04:48What? What? What demonstration?
0:04:48 > 0:04:50I've been awake the whole time.
0:04:50 > 0:04:52Now, your heart was beating when you were
0:04:52 > 0:04:55a six-week-old embryo inside your mum,
0:04:55 > 0:04:57just the size of a raisin.
0:04:57 > 0:05:00Your heart is made up of millions of tiny cells
0:05:00 > 0:05:03and each one of those cells beats on its own.
0:05:03 > 0:05:07And here's one of them. This is a single heart cell.
0:05:07 > 0:05:10It just won't stop beating, even without its mates.
0:05:10 > 0:05:12Absolutely brilliant, isn't it, Xand?
0:05:12 > 0:05:14- Xand? Xand!- What?
0:05:14 > 0:05:16It's not nap time!
0:05:16 > 0:05:18Now, if you ask more of your body,
0:05:18 > 0:05:20say when you exercise...
0:05:20 > 0:05:22- Exercise?- Yes, Xand, exercise.
0:05:22 > 0:05:25..your heart will step up to help you out.
0:05:25 > 0:05:29Right, give me some nice, big star jumps, please, Xand.
0:05:29 > 0:05:33When you exercise, your muscles need lots more blood and oxygen.
0:05:33 > 0:05:36To provide this the heart speeds up.
0:05:36 > 0:05:39As you can see, Xand's heart rate is much higher now than when he
0:05:39 > 0:05:41was lying down. Even at rest,
0:05:41 > 0:05:44it beats around 100,000 times a day.
0:05:44 > 0:05:48So, you've seen how your heart beats at different rates
0:05:48 > 0:05:49depending on what you're doing.
0:05:49 > 0:05:52But how does your heart actually work?
0:05:52 > 0:05:55How does it get all that blood where you need it, when you need it?
0:05:55 > 0:05:57Well, we're going to show you.
0:06:01 > 0:06:04Check this out! This is a real heart.
0:06:04 > 0:06:07It's from a pig, but don't let that put you off.
0:06:07 > 0:06:09It's very similar to a human heart
0:06:09 > 0:06:11and it's a pump with no equal.
0:06:11 > 0:06:15Blood arrives in the heart all tired and out of oxygen.
0:06:15 > 0:06:20The heart pumps it straight to the lungs, where it collects new oxygen.
0:06:20 > 0:06:22Back at the heart, it's given a mega pump,
0:06:22 > 0:06:25which scoots it all around the body.
0:06:25 > 0:06:28And there's no chance of it going the wrong way, thanks to the
0:06:28 > 0:06:29heart's special valves.
0:06:29 > 0:06:32And if you add up all the blood each of these beats
0:06:32 > 0:06:34pushes around the body it comes to
0:06:34 > 0:06:377,200 litres a day.
0:06:37 > 0:06:40That's enough to fill 93 bathtubs.
0:06:40 > 0:06:41We've only got one bathtub!
0:06:41 > 0:06:44And if you fill it with blood, where am I going to have my bath?
0:06:44 > 0:06:46- HE SNIFFS - You need a bath.
0:06:46 > 0:06:48Now, to show you how it manages to do that
0:06:48 > 0:06:51we're going to cut our pig's heart open.
0:06:51 > 0:06:55Looking inside the heart is absolutely amazing.
0:06:55 > 0:06:57The muscle here is very thick.
0:06:57 > 0:06:59This makes the heart really strong
0:06:59 > 0:07:03and that's how it's able to pump blood right around your body.
0:07:03 > 0:07:06But it couldn't do it without one important bit of the heart -
0:07:06 > 0:07:08the valves, and you can see them here.
0:07:08 > 0:07:11Their job is to make sure the blood goes in the right direction.
0:07:11 > 0:07:14To see how the heart does its incredible job,
0:07:14 > 0:07:16we've set up our real heart,
0:07:16 > 0:07:18using plastic tubes as blood vessels
0:07:18 > 0:07:21and green water to do the job of your blood.
0:07:21 > 0:07:24OK, Chris, lift your bucket up a little bit.
0:07:24 > 0:07:26First the heart fills with blood.
0:07:26 > 0:07:28It does this every time it beats.
0:07:28 > 0:07:30- Whoa, look at that!- Look at it fill!
0:07:30 > 0:07:32OK, and squeeze now.
0:07:32 > 0:07:35Xand's hands are doing what the heart does by itself
0:07:35 > 0:07:37thousands of times a day.
0:07:37 > 0:07:40And the heart is clever, because everything's going into that
0:07:40 > 0:07:43bucket and nothing's going back into Chris' bucket.
0:07:43 > 0:07:46The heart only pumps blood in one direction.
0:07:46 > 0:07:48And that's thanks to the valves,
0:07:48 > 0:07:50not to Harry Styles.
0:07:50 > 0:07:52But there's one question that still remains.
0:07:52 > 0:07:56How powerful is the heart and how far can it squirt blood?
0:07:56 > 0:07:58I've filled the heart.
0:07:58 > 0:08:01Now, you hold that bit. I'm going to get the bucket.
0:08:01 > 0:08:03Give me that. Quick, quick! Get the bucket.
0:08:03 > 0:08:06- OK, see if you can get it... - About a foot?
0:08:06 > 0:08:08- Yeah, about half a metre. Go! - OK, go!
0:08:08 > 0:08:12- Yay!- That's not bad, but I think we can go further.
0:08:12 > 0:08:15- Let's refill the heart. - OK, quick, fill it up again.
0:08:15 > 0:08:18But Xand's squeeze is not nearly as strong as a heartbeat.
0:08:18 > 0:08:20Just aim it all in the bucket.
0:08:20 > 0:08:23- Ready?- OK. Three, two, one.
0:08:23 > 0:08:25XAND GROANS AND LAUGHS
0:08:26 > 0:08:29Xand gets quite a lot beyond the bucket...
0:08:29 > 0:08:31You just didn't get any in the bucket.
0:08:31 > 0:08:34But I still think that's impressive, about two and a half metres.
0:08:34 > 0:08:36Two and a half metres is pretty good,
0:08:36 > 0:08:39but a live heart actually beats powerfully enough
0:08:39 > 0:08:42to squirt blood more than ten metres.
0:08:42 > 0:08:46Ten metres? That's more powerful than my best water pistol!
0:08:46 > 0:08:48Luckily, Xand's not ten metres away.
0:08:54 > 0:08:59Now, we're getting Ouch & About with our mobile clinic.
0:08:59 > 0:09:01Today we're at a theme park
0:09:01 > 0:09:04to help solve your medical mysteries.
0:09:04 > 0:09:06If you're anxious about an ailment,
0:09:06 > 0:09:08or curious about a condition,
0:09:08 > 0:09:11then the Ouch-Mobile is the place for you.
0:09:11 > 0:09:12That is incredible.
0:09:12 > 0:09:15Chris is preparing the clinic ready for his first patient.
0:09:15 > 0:09:19And Xand is out in the park to answer your burning questions.
0:09:19 > 0:09:22At the clinic, Chris is open for business.
0:09:22 > 0:09:23Next patient, please.
0:09:23 > 0:09:27First in is nine-year-old Shoma with a question about some
0:09:27 > 0:09:29frightful findings on his feet.
0:09:29 > 0:09:33I've got a bunch of verrucas on my foot that won't go away.
0:09:33 > 0:09:35Well, what have you got to say about this, Chris?
0:09:35 > 0:09:37This sounds like a rare case of
0:09:40 > 0:09:42And breathe.
0:09:42 > 0:09:44Now, let's have a look.
0:09:44 > 0:09:47Yeah, one, two, three...
0:09:47 > 0:09:49There's a little cluster of them, here.
0:09:49 > 0:09:53Now, that's the big daddy verruca, there,
0:09:53 > 0:09:54then more up here.
0:09:54 > 0:09:56That's an impressive nine verrucas
0:09:56 > 0:09:58on one foot.
0:09:58 > 0:10:00How do you get verrucas?
0:10:00 > 0:10:03So, verrucas are viruses. So, you get them from walking around
0:10:03 > 0:10:06where other people with verrucas have walked.
0:10:06 > 0:10:08The virus has got quite a cool name.
0:10:08 > 0:10:09- Want to know what it is?- Yeah.
0:10:09 > 0:10:11It's called the:
0:10:11 > 0:10:12Can you say that?
0:10:14 > 0:10:16Nice one, Shoma.
0:10:16 > 0:10:20The virus causes your skin to grow in an uncontrollable way,
0:10:20 > 0:10:22leading to these lumps.
0:10:22 > 0:10:25But the good news is, they often go away on their own.
0:10:25 > 0:10:28The important thing if you have a verruca is to not spread it
0:10:28 > 0:10:30to other people. So, when you go swimming you've got to
0:10:30 > 0:10:34wear a verruca sock. When you play PE you've got to keep your shoes on.
0:10:34 > 0:10:36And don't worry if you have verrucas,
0:10:36 > 0:10:39they'll probably soon disappear by themselves.
0:10:39 > 0:10:43Away from the clinic, Xand is Ouch & About in the park.
0:10:43 > 0:10:45Now, let's see if there are any medical mysteries
0:10:45 > 0:10:48or maybe people have got some questions for me.
0:10:48 > 0:10:51Why does your heart beat fast on roller-coasters?
0:10:51 > 0:10:52When you're frightened,
0:10:52 > 0:10:54your body releases a hormone
0:10:54 > 0:10:58called adrenaline and that makes your heart beat faster,
0:10:58 > 0:11:01cos your body thinks it might have to run away.
0:11:01 > 0:11:04Like if a tiger attacked you, you'd get a load of adrenaline,
0:11:04 > 0:11:06your heart would beat fast and you'd run away faster.
0:11:06 > 0:11:09That's what your body's doing, preparing to run away,
0:11:09 > 0:11:12even though you're strapped into a roller-coaster.
0:11:12 > 0:11:14Xand, look what I did today!
0:11:14 > 0:11:16Oh, no! That's terrible. What happened?
0:11:16 > 0:11:19Well, I was going on the ride and I hit my leg on the side of the ride.
0:11:19 > 0:11:20- Ah, was it painful?- Yeah.
0:11:20 > 0:11:23When you get a bruise, you break the blood vessels under your skin.
0:11:23 > 0:11:25What you're seeing is bleeding under the skin.
0:11:25 > 0:11:28All that stuff that looks black is actually red blood
0:11:28 > 0:11:31and it'll gradually change colour as it heals.
0:11:31 > 0:11:34Back at the Ouch-Mobile, there's a new case in the waiting room.
0:11:34 > 0:11:35Hi, Dr Chris.
0:11:35 > 0:11:39It's ten-year-old Mohammed and he's got something incredible to show us.
0:11:39 > 0:11:42Mohammed, why have you come to the Ouch-Mobile today?
0:11:42 > 0:11:45I can fold my ear and stick it in this hole here.
0:11:45 > 0:11:47You can fold your ear in what?
0:11:47 > 0:11:48Diagnose this, Chris.
0:11:48 > 0:11:51So, this sounds like a very rare case of
0:11:55 > 0:11:57Well, I can't wait to see it.
0:11:57 > 0:11:58Wow!
0:11:58 > 0:12:01That is the most bendy ear I've ever seen.
0:12:01 > 0:12:03OK, Mohammed, give it a little wiggle
0:12:03 > 0:12:05and make it pop out.
0:12:05 > 0:12:07Well, let's see that again.
0:12:07 > 0:12:10How come I can do that with my ear?
0:12:10 > 0:12:14Well, inside your ear you've got some very bendy stuff called
0:12:14 > 0:12:17cartilage and it's the same stuff that's in your nose.
0:12:17 > 0:12:20So, I don't think there's anything wrong with your cartilage.
0:12:20 > 0:12:22It's just nice and soft and you've got bendy ears.
0:12:22 > 0:12:24Job done for today.
0:12:27 > 0:12:29Still to come...
0:12:29 > 0:12:31Chris is on call in the West Midlands
0:12:31 > 0:12:32with a rapid response unit...
0:12:32 > 0:12:35- John, have some nice, big breaths. - That's it.
0:12:35 > 0:12:38..we show you how to cope with a medical mishap...
0:12:38 > 0:12:40Yeah, that feels much better.
0:12:40 > 0:12:43..and I meet a dog trained to save lives.
0:12:46 > 0:12:48Back in Accident and Emergency,
0:12:48 > 0:12:51Logan is waiting for an operation on his abscess.
0:12:51 > 0:12:54Ooh, I love a good abscess.
0:12:55 > 0:12:58But how did he get that swollen cheek and eye?
0:12:58 > 0:13:02It all started one night when a bad pain in Logan's tooth
0:13:02 > 0:13:04disturbed his sleep.
0:13:04 > 0:13:07He woke up his mum and not only did he have a sore tooth,
0:13:07 > 0:13:09he had a red, swollen face
0:13:09 > 0:13:12that made him look a little odd. Ouch.
0:13:12 > 0:13:16Logan's tooth is badly infected and needs something done about it.
0:13:16 > 0:13:19What we need to do, really, is get that tooth out.
0:13:19 > 0:13:23So, he's going to need an operation to remove the gnarly gnasher.
0:13:23 > 0:13:27But our patient has his own ideas about what's going on in his mouth.
0:13:27 > 0:13:31I'm waiting for someone to take the bad soldiers out
0:13:31 > 0:13:33and the bad tooth out.
0:13:33 > 0:13:35Whoa, whoa, whoa, whoa, whoa! Bad soldiers?
0:13:35 > 0:13:39The bad soldiers were attacking that to make it more bigger,
0:13:39 > 0:13:43the good soldiers were fighting the battle.
0:13:43 > 0:13:45But who wins, Logan?
0:13:45 > 0:13:47The good soldiers win,
0:13:47 > 0:13:51because there's only about
0:13:51 > 0:13:5341 bad soldiers and...
0:13:54 > 0:13:57..57 good soldiers.
0:13:57 > 0:13:59Huzzah, brilliant!
0:14:01 > 0:14:04Best get you off to surgery, Logan.
0:14:04 > 0:14:08First, Logan is put to sleep, so he won't feel a thing.
0:14:08 > 0:14:10Performing the operation today is:
0:14:13 > 0:14:17He removes Logan's problem tooth using extraction forceps.
0:14:17 > 0:14:21At the same time, he spots some other broken teeth in Logan's mouth
0:14:21 > 0:14:22and he takes those out, too.
0:14:24 > 0:14:26That's OK, though. These are his milk teeth
0:14:26 > 0:14:29and replacements will soon grow in.
0:14:29 > 0:14:33Surgery done and dusted, Logan's abscess has been fixed
0:14:33 > 0:14:36and he's had a few other potential problems solved as well.
0:14:36 > 0:14:39We just took out these five teeth and, hopefully, he'll get big,
0:14:39 > 0:14:42new, shiny teeth in to replace the ones we've taken out.
0:14:42 > 0:14:45Logan just has to make sure that he's cleaning his teeth
0:14:45 > 0:14:46really effectively now.
0:14:46 > 0:14:50He needs to be brushing twice a day, using a good fluoride toothpaste
0:14:50 > 0:14:54and he has to be careful how many sweets he's eating, too.
0:14:54 > 0:14:58Our patient is wide awake and the swelling has gone down.
0:14:58 > 0:15:01So, that's what you look like normally?
0:15:01 > 0:15:04Logan's usually a chatterbox, but it's evening time on the
0:15:04 > 0:15:07children's ward, so he has to be extra quiet.
0:15:07 > 0:15:10- WHISPERS - Can you tell us how you're feeling?
0:15:10 > 0:15:12We'll take that as a good sign.
0:15:12 > 0:15:14So good, in fact, he's off home.
0:15:15 > 0:15:17Just like a good little soldier.
0:15:17 > 0:15:18BOTH: Bye!
0:15:21 > 0:15:24In the UK, there are hundreds of rapid response
0:15:24 > 0:15:26medical teams on standby...
0:15:26 > 0:15:29And they have to get to the scene of an emergency in minutes.
0:15:31 > 0:15:35We're on call with the UK emergency services, showing you what
0:15:35 > 0:15:37it's really like on the front line saving lives.
0:15:41 > 0:15:45This state-of-the-art rapid response vehicle can get to the
0:15:45 > 0:15:48scene of a medical emergency in minutes. And today, I'm going
0:15:48 > 0:15:52out in it to show you what it's like to be a life-saving paramedic.
0:15:54 > 0:15:58If you have an accident, this fast medical service is ready to help
0:15:58 > 0:16:0024 hours a day.
0:16:00 > 0:16:02You never know what we're going to find when we get there,
0:16:02 > 0:16:06but I've got my camera and, of course, Eric's in the back with his.
0:16:06 > 0:16:09So, we've got it covered from all angles.
0:16:09 > 0:16:12On call with me is paramedic Jan Vann.
0:16:13 > 0:16:16She can do 20 emergency callouts in a day.
0:16:18 > 0:16:19And a new case is just in.
0:16:20 > 0:16:24We're driving toward the emergency and the call is still going on.
0:16:24 > 0:16:27And it's just come in that it's a 75-year-old man.
0:16:27 > 0:16:30Jan is the first medic on the scene to see Don.
0:16:30 > 0:16:32- Hello, Donald. - Hello.
0:16:32 > 0:16:34- Have you got any pain anywhere? - In me hip.
0:16:34 > 0:16:36Right, we need to try and get you onto your back
0:16:36 > 0:16:39so I can assess whether we think you've broken it or not.
0:16:39 > 0:16:42Right, I'm going to pull on your trousers.
0:16:42 > 0:16:45It's clear Don's had a nasty fall and to make him more
0:16:45 > 0:16:48comfortable, Jan wants to move him onto his back.
0:16:48 > 0:16:51Give us your arm, then, so I can do your blood pressure.
0:16:51 > 0:16:54Are you happy to go to the hospital today and maybe get an X-ray, yeah?
0:16:54 > 0:16:55Yeah. Anything.
0:16:55 > 0:16:59To help Don with his injury, Jan gives him some pain relief.
0:16:59 > 0:17:00This goes over your face
0:17:00 > 0:17:03and you breathe it in and it makes this funny noise.
0:17:03 > 0:17:05Don, have some nice, big breaths.
0:17:05 > 0:17:10Don's getting some Entonox, also known as laughing gas.
0:17:10 > 0:17:12That's the hissing you can hear,
0:17:12 > 0:17:14so he should start feeling like he's in a bit less pain.
0:17:14 > 0:17:16I've called for an ambulance to back us up
0:17:16 > 0:17:18cos we're going to get him into the hospital and
0:17:18 > 0:17:20get him an X-ray on his hip.
0:17:20 > 0:17:23We think he may have broke it. We can't treat that at home.
0:17:23 > 0:17:24He needs to be seen at the hospital.
0:17:24 > 0:17:27With a suspected broken hip, the ambulance crew arrive
0:17:27 > 0:17:29with some special equipment.
0:17:29 > 0:17:32The ambulance team are using a really cool piece of kit called
0:17:32 > 0:17:36a scoop. And it comes in two halves, which you can slide together
0:17:36 > 0:17:39under the patient. They meet in the middle and then it's like he's on a
0:17:39 > 0:17:42bed, and they just pick him up and scoop him straight to hospital.
0:17:42 > 0:17:44Don, how do you feel?
0:17:44 > 0:17:47- A little bit easier now. - A bit easier? Good.
0:17:47 > 0:17:49- Ready?- Ready, set.
0:17:49 > 0:17:52Jan did a great job helping Don with his pain
0:17:52 > 0:17:54and making him more comfortable.
0:17:54 > 0:17:56Now he's off to hospital, they'll X-ray him
0:17:56 > 0:17:59and see if they can do anything to treat the cause of that pain
0:17:59 > 0:18:01in his hip.
0:18:02 > 0:18:06And if you ever have an emergency, there are hundreds of similar
0:18:06 > 0:18:08crews around the country, ready to help.
0:18:19 > 0:18:21Theirs are just bigger.
0:18:21 > 0:18:23But all bones need looking after.
0:18:27 > 0:18:29Cycling in the park, brilliant exercise
0:18:29 > 0:18:32and a brilliant way to get some sunshine.
0:18:32 > 0:18:36But of course, cycling can also be dangerous!
0:18:38 > 0:18:41You could cycle into a hedge and hit your head.
0:18:43 > 0:18:46That's why I'm wearing this snazzy helmet.
0:18:46 > 0:18:49Or you could fall off and get a nasty graze on your knee.
0:18:49 > 0:18:51CRASH!
0:18:51 > 0:18:54That's why I'm wearing these snazzy leggings.
0:18:54 > 0:18:56And finally, of course, you need to
0:18:56 > 0:18:58make sure your bike is properly maintained.
0:18:58 > 0:19:00You wouldn't want to squeeze your brakes and...
0:19:00 > 0:19:02Uh-oh, my brakes!
0:19:02 > 0:19:04- Ah! - My brakes!
0:19:04 > 0:19:06Ahh!
0:19:06 > 0:19:07THUD!
0:19:07 > 0:19:09- Oh...- Oh.
0:19:09 > 0:19:12Well, thanks to my helmet, I don't have a head injury.
0:19:12 > 0:19:15Me neither. And thanks to these leggings, I haven't got any grazes.
0:19:15 > 0:19:17But on the downside,
0:19:17 > 0:19:19I think I've broken my arm.
0:19:19 > 0:19:21Sounds like an injury alert.
0:19:44 > 0:19:45You guessed it,
0:19:45 > 0:19:46the answer is B!
0:19:46 > 0:19:48Here's how it's done.
0:19:48 > 0:19:51So, Chris, put your arm against your body, gently as you can.
0:19:51 > 0:19:55- It really hurts if I move it. - And then what we can do is use Chris'
0:19:55 > 0:19:57jumper to support the arm itself.
0:19:57 > 0:20:00- So, if I go very gently, trying not to move the arm.- Ow.
0:20:00 > 0:20:04Now, remember, we're showing you what to do in an emergency.
0:20:04 > 0:20:07Never do this on your own, unless it IS an emergency.
0:20:07 > 0:20:08Always try and find an adult.
0:20:08 > 0:20:10How's that? Can you now relax your arm?
0:20:10 > 0:20:13- Yeah, that feels much better. - Yeah, more comfortable, isn't it?
0:20:13 > 0:20:15So, once he's feeling better, we can get him to hospital.
0:20:15 > 0:20:17He's going to be more comfortable moving.
0:20:17 > 0:20:20We can get him X-rayed and see what's going on.
0:20:20 > 0:20:22So, now it's this lot's turn to have a go.
0:20:24 > 0:20:25Ow! Ah!
0:20:25 > 0:20:27SCREAMING
0:20:27 > 0:20:30That's really good. So, try and be very gentle with that arm.
0:20:30 > 0:20:32How's that feeling? Can you relax that arm now?
0:20:32 > 0:20:35- Feels pretty good? - Yeah, it feels a lot better.
0:20:35 > 0:20:37Obviously, most of the time, when you've got a broken arm
0:20:37 > 0:20:40you don't need to call an ambulance. You can get in a car
0:20:40 > 0:20:42and go to A&E yourself.
0:20:42 > 0:20:44So, if you think you might have broken your arm,
0:20:44 > 0:20:48support it to stop it moving using your hand or clothing or cushions,
0:20:48 > 0:20:51and tell an adult or call 999.
0:20:52 > 0:20:54Are you sure it's broken, Chris?
0:20:54 > 0:20:56Better safe than sorry, Xand.
0:21:06 > 0:21:10Your body is amazing, but sometimes it needs fixing.
0:21:10 > 0:21:13All over the country there are special teams of professionals
0:21:13 > 0:21:17trained to tackle medical mysteries, and not all of them are human.
0:21:18 > 0:21:21Dogs have 200 million smell receptors,
0:21:21 > 0:21:24making them really superior sniffers.
0:21:24 > 0:21:28And dogs' noses don't get much better than Shirley's here,
0:21:28 > 0:21:30because Shirley's nose is a bit of a lifesaver.
0:21:31 > 0:21:35Shirley's nose has been trained to help Rebecca.
0:21:35 > 0:21:37Rebecca has Type 1 diabetes.
0:21:37 > 0:21:41This means that her body doesn't produce a chemical called insulin.
0:21:41 > 0:21:44And amazingly, Shirley's incredible nose can sniff out
0:21:44 > 0:21:47when there are problems.
0:21:47 > 0:21:50Insulin's job is to make sure you have just the right amount of...
0:21:50 > 0:21:52- WHISTLE BLOWS - ..sugar in your blood.
0:21:52 > 0:21:54When your body doesn't produce insulin,
0:21:54 > 0:21:57blood sugar gets out of control.
0:21:57 > 0:22:00So, if your blood sugar is too high, you inject insulin.
0:22:00 > 0:22:01WHISTLE BLOWS
0:22:01 > 0:22:04And if it's too low, you have to eat something sweet.
0:22:04 > 0:22:07How many times a day do you have to take insulin?
0:22:07 > 0:22:10Four times. One for breakfast,
0:22:10 > 0:22:12one for lunch, dinner
0:22:12 > 0:22:15and night-time.
0:22:15 > 0:22:19But Rebecca's blood sugar varies depending on what she's up to,
0:22:19 > 0:22:21and Shirley can spot it.
0:22:21 > 0:22:24This is something that humans could never do.
0:22:24 > 0:22:26She's able to detect changes in Rebecca's
0:22:26 > 0:22:28breath as soon as they happen,
0:22:28 > 0:22:30and, usually, that's before Rebecca
0:22:30 > 0:22:34has even the slightest idea that anything's wrong.
0:22:34 > 0:22:37So, this is definitely a dog that thinks there's something going on?
0:22:37 > 0:22:40- Yeah.- When Shirley smells a problem, she licks Rebecca
0:22:40 > 0:22:42and her blood can be tested.
0:22:45 > 0:22:462.8.
0:22:46 > 0:22:49Then she can inject more insulin or get help
0:22:49 > 0:22:50before things get dangerous.
0:22:50 > 0:22:52What would have happened before you had Shirley?
0:22:52 > 0:22:55I would have had the ambulance once or twice a week.
0:22:55 > 0:22:57So, since you've had Shirley,
0:22:57 > 0:22:59how many times have you had an ambulance?
0:22:59 > 0:23:01Erm, like once in three years.
0:23:02 > 0:23:05Shirley's on call for Rebecca 24/7,
0:23:05 > 0:23:08checking on her right through the night.
0:23:08 > 0:23:10Rebecca leaves for school in the morning, while Shirley catches
0:23:10 > 0:23:13up on some sleep, but she soon wakes up for duty.
0:23:17 > 0:23:19Do you actually feel happier that Rebecca's safer
0:23:19 > 0:23:21when Shirley's around?
0:23:21 > 0:23:25Yeah, very. Shirley's always on the sniff.
0:23:27 > 0:23:31And Shirley's sniffing keeps Rebecca safe.
0:23:31 > 0:23:34Shirley has completely changed Rebecca's life,
0:23:34 > 0:23:37because although Rebecca will always have Type 1 diabetes,
0:23:37 > 0:23:40now, thanks to Shirley's super-sensitive sniffer,
0:23:40 > 0:23:42rather than calling all those ambulances,
0:23:42 > 0:23:45all she gets is lots of big, wet doggy kisses.
0:23:45 > 0:23:47Yum!
0:23:50 > 0:23:53Let's go back to Accident and Emergency to meet our next patient.
0:23:53 > 0:23:57And you're not going to believe this one.
0:23:57 > 0:24:00In Liverpool Accident and Emergency, six-year-old Gracie
0:24:00 > 0:24:04has arrived with her mum and a big bandage on her finger.
0:24:04 > 0:24:06I've got a slipped finger.
0:24:06 > 0:24:08A slipped finger?
0:24:08 > 0:24:10It was bleeding a lot.
0:24:10 > 0:24:12Ah, a slit finger!
0:24:12 > 0:24:14Sounds like a nasty cut.
0:24:14 > 0:24:17I think the doctor's going to make it all better.
0:24:17 > 0:24:20That's right, but how did the ghastly gash happen?
0:24:21 > 0:24:24Well, Chris, once upon a time in a faraway land...
0:24:24 > 0:24:27Erm, Liverpool, Xand. Gracie's from Liverpool.
0:24:27 > 0:24:30Go with it, Chris. We're in the fairy-tale land of Liverpool.
0:24:30 > 0:24:32Erm, righto.
0:24:32 > 0:24:36Princess Gracie was in her castle admiring her mother's jewels.
0:24:36 > 0:24:38Hang on, who's that?
0:24:38 > 0:24:41A fairy, obviously. And she's flown off with the diamond earring.
0:24:41 > 0:24:43Erm, OK.
0:24:43 > 0:24:46And Gracie was trying to get it back, when all of a sudden
0:24:46 > 0:24:48the earring flew under the roaring...
0:24:48 > 0:24:51Xand, that's an electric fire.
0:24:51 > 0:24:52Oh, all right, fine.
0:24:52 > 0:24:55But as she tried to retrieve the earring her hand got stuck.
0:24:55 > 0:24:56Uh-oh!
0:24:56 > 0:25:01- And when she pulled it out, her finger sliced open.- Ouch.
0:25:01 > 0:25:04There's a bit of a queue in Accident and Emergency.
0:25:04 > 0:25:06So, while we're waiting, why don't you tell us
0:25:06 > 0:25:08something about yourself, Gracie?
0:25:08 > 0:25:10I've never been to A&E before.
0:25:10 > 0:25:14- Never been to A&E before? Well done. - I've got pierced ears.
0:25:14 > 0:25:16Ah, she likes her bling!
0:25:16 > 0:25:18These are my plaits.
0:25:18 > 0:25:20- They'd suit you, Xand. - Oh, thank you.
0:25:20 > 0:25:23That's enough about you, Gracie.
0:25:23 > 0:25:28Time for Nurse Practitioner Julia Maxted to sort that cut out.
0:25:28 > 0:25:31Can you just bend your finger, the little end bit?
0:25:31 > 0:25:33Lovely, and straighten it again.
0:25:33 > 0:25:35First things first, Nurse Julia needs to figure out
0:25:35 > 0:25:39if Gracie's cut is so deep it's damaged the insides.
0:25:39 > 0:25:41Ooh, you're very brave.
0:25:41 > 0:25:44We do that to just check that the ligaments are all working.
0:25:44 > 0:25:47A ligament is the tissue that joins a bone to a bone.
0:25:47 > 0:25:50Can you feel me touching there and there?
0:25:50 > 0:25:51Good girl.
0:25:51 > 0:25:54- That's quite a cut you've got there, Gracie.- Yeah.
0:25:54 > 0:25:56But the nurse is happy there's no internal damage done,
0:25:56 > 0:25:59so she can clean that cut and make sure
0:25:59 > 0:26:02there's no dirt lurking deep inside.
0:26:02 > 0:26:04Squeeze my hand, as hard as you can.
0:26:04 > 0:26:06Whoa, she's strong!
0:26:08 > 0:26:12To help the cut heal and join Gracie's flesh back together,
0:26:12 > 0:26:15the nurse has some special paper stitches.
0:26:15 > 0:26:19And then we just pull the edges of your cut together.
0:26:19 > 0:26:22With her finger taped back together, Nurse Julia is using
0:26:22 > 0:26:25a hi-tech bandage strapper device...thingy.
0:26:25 > 0:26:28A what? It's just a bandage applicator, Xand.
0:26:28 > 0:26:30- Yeah, well, it's pretty cool though. - It is.
