0:00:23 > 0:00:24He's Dr Chris.
0:00:24 > 0:00:26He's Dr Xand.
0:00:26 > 0:00:27Yes, he's still got his beard.
0:00:27 > 0:00:30And we're still identical twins!
0:00:30 > 0:00:33Your body is amazing and we're going to show you why.
0:00:35 > 0:00:38We are head-to-head in Operation Takeover.
0:00:38 > 0:00:41BOTH: Man overboard!
0:00:41 > 0:00:42Ouch And About hits the wards.
0:00:42 > 0:00:44What kind of ambulance did you get?
0:00:44 > 0:00:47I didn't get an ambulance, I got a helicopter.
0:00:47 > 0:00:48First aid is back.
0:00:48 > 0:00:50We do need to get Xand to hospital.
0:00:50 > 0:00:52Meet our brilliant new Ouch patients.
0:00:52 > 0:00:54I'm off to my physio appointment.
0:00:54 > 0:00:56And our lab experiments...
0:00:56 > 0:00:57Argh!
0:00:57 > 0:00:59..will blow your mind.
0:00:59 > 0:01:02That's an amazing view.
0:01:02 > 0:01:03Are you ready to join us?
0:01:06 > 0:01:08I can't see a thing!
0:01:09 > 0:01:12- Coming up today... - ..on Operation Ouch!
0:01:15 > 0:01:17We have liftoff.
0:01:17 > 0:01:19We are now at maximum altitude.
0:01:21 > 0:01:22We take the plunge.
0:01:22 > 0:01:24That's not good.
0:01:24 > 0:01:27And we get our teeth stuck into things.
0:01:27 > 0:01:30That's disgusting. But first...
0:01:30 > 0:01:33The doctors and nurses in A&E never know what's around the next corner.
0:01:33 > 0:01:36- Oh!- Ow!
0:01:36 > 0:01:38BOTH: Let's find out, shall we?
0:01:38 > 0:01:42Today, waiting with his mum in the emergency department
0:01:42 > 0:01:43is nine-year-old Will,
0:01:43 > 0:01:44who is mad about motocross.
0:01:44 > 0:01:47I love riding my bike all the time.
0:01:47 > 0:01:51If someone said to quit, I'd just look at them, like...
0:01:52 > 0:01:55- ..like that.- You're clearly bonkers about bikes, Will,
0:01:55 > 0:01:57but isn't it a bit dangerous?
0:01:57 > 0:02:00In the last few months, I've had about four breakages.
0:02:00 > 0:02:05Two collarbones, my patella and my tibia.
0:02:05 > 0:02:07Crikey! What's happened this time?
0:02:07 > 0:02:11I banged my kneecap on a big rock.
0:02:11 > 0:02:13Ooh. Let's find out more.
0:02:13 > 0:02:17Will was competing in the British Motocross Youth Championships in
0:02:17 > 0:02:20- Oxfordshire. - Chris, I'm loving the safety gear.
0:02:20 > 0:02:23Yes, even down to the blue gloves.
0:02:23 > 0:02:26The race began. And here comes number 31, it's Will.
0:02:26 > 0:02:28He's coming from the back.
0:02:28 > 0:02:30He's moving further up the field.
0:02:30 > 0:02:32Chris, you're really getting into this.
0:02:32 > 0:02:34It's all so exciting!
0:02:34 > 0:02:35Will's into sixth place.
0:02:35 > 0:02:37- Go, Will!- He's accelerating hard.
0:02:37 > 0:02:40Oh, no! It's turned into a wheelie!
0:02:40 > 0:02:42The bike is out of control!
0:02:42 > 0:02:44- Yikes!- Number 31 is off his bike.
0:02:44 > 0:02:47He's landed knee first onto a rock.
0:02:48 > 0:02:49Ouch.
0:02:49 > 0:02:53Will went straight to the nearest hospital and had X-rays taken soon
0:02:53 > 0:02:57- after he was injured.- They said it was a broken patella.
0:02:57 > 0:03:00Your patella is your kneecap, in case you were wondering.
0:03:00 > 0:03:04So, it's off to see bone specialist Dr Janet Cumberland to find out for
0:03:04 > 0:03:06- sure.- So when I look at your X-ray,
0:03:06 > 0:03:11it doesn't jump out at me as being a break at the end of the kneecap.
0:03:11 > 0:03:14That could be good news, Xand.
0:03:14 > 0:03:17Dr Janet cuts off Will's plaster to take a closer look.
0:03:17 > 0:03:21- Does that hurt your hip at all? - No.- If I do that, does that hurt?
0:03:21 > 0:03:24- Not really.- And when I pressed on the end of his kneecap,
0:03:24 > 0:03:26it didn't really hurt them very much.
0:03:26 > 0:03:29- You point to where that hurts.- Here.
0:03:29 > 0:03:31But it did hurt him over the bruised bits.
0:03:31 > 0:03:34Although Dr Alison doesn't think Will's bone is broken,
0:03:34 > 0:03:38she is still concerned and want to send him for some fresh X-rays.
0:03:38 > 0:03:41If we do the X-rays in another position,
0:03:41 > 0:03:45we can see if there is fluid in the knee, rather than a broken bone.
0:03:45 > 0:03:47Find out later how Will gets on.
0:03:57 > 0:03:59So be proud of your gnashers.
0:04:03 > 0:04:04And now to our lab.
0:04:06 > 0:04:09It's time for some big body experiments.
0:04:09 > 0:04:12Some of them gory... This is not for the squeamish.
0:04:12 > 0:04:13Some extreme.
0:04:13 > 0:04:16It's freezing! We are ready.
0:04:16 > 0:04:18Are you?
0:04:18 > 0:04:20Just don't try anything you see here at home.
0:04:23 > 0:04:25Oh, Chris, you're just in time.
0:04:25 > 0:04:27- It's 2.30.- So?
0:04:27 > 0:04:29You know what happens at 2.30.
0:04:29 > 0:04:30Erm, is it time for your nap?
0:04:30 > 0:04:36No, at 2.30 - tooth hurty - we go to the dentist.
0:04:36 > 0:04:39Tooth hurty. Anyway, come on, we've got to get an X-ray of your teeth.
0:04:39 > 0:04:42- Fine, OK. - To the cupboard of everything.
0:04:44 > 0:04:45- Hi, Annie.- Hi, Chris.
0:04:45 > 0:04:49Wow, there really is everything in your cupboard, Xand.
0:04:49 > 0:04:51X-ray complete.
0:04:53 > 0:04:56Now this is called an orthopantomogram.
0:04:56 > 0:04:58Oh, no, it isn't!
0:04:58 > 0:05:00Oh, yes, it's... It's not that kind of panto, Xand!
0:05:00 > 0:05:05The panto stands for the technique used, panoramic tomography.
0:05:05 > 0:05:08Now, the amazing thing about this is that you can see the whole tooth.
0:05:08 > 0:05:11If you look in your mouth, you can actually see the top third,
0:05:11 > 0:05:13that's the crown, the white bit.
0:05:13 > 0:05:16But on the X-ray, we can see what's below the gum.
0:05:16 > 0:05:20Your teeth have roots and they're twice as long as the crown.
0:05:20 > 0:05:22Now, that X-ray is really cool, Chris,
0:05:22 > 0:05:26but there is a lot more going on inside your tooth
0:05:26 > 0:05:28and I'm going to show you using
0:05:28 > 0:05:31this huge model.
0:05:31 > 0:05:33But, Xand, we don't need a huge model
0:05:33 > 0:05:35because today we've got the real thing.
0:05:37 > 0:05:40This is a tooth that's been given to us by a dentist
0:05:40 > 0:05:43- that's been cut in half.- What?!
0:05:43 > 0:05:45You cut the dentist in half?!
0:05:45 > 0:05:47No, Xand, the tooth has been cut in half.
0:05:47 > 0:05:50The dentist is absolutely fine.
0:05:50 > 0:05:54Phew! Now, your teeth are made of amazing stuff.
0:05:54 > 0:05:57The glossy white surface layer is called enamel.
0:05:57 > 0:06:01It protects the whole tooth and it's the hardest substance in your entire
0:06:01 > 0:06:06body, but it can be worn away by acidic drinks and sugary foods
0:06:06 > 0:06:09and it won't grow back once it's gone, so look after it.
0:06:09 > 0:06:12Now, underneath is the layer called the dentine,
0:06:12 > 0:06:15and underneath the dentine is the pulp,
0:06:15 > 0:06:17and they're sensitive layers of living tissue
0:06:17 > 0:06:19and they support the enamel.
0:06:19 > 0:06:20They both contain nerves,
0:06:20 > 0:06:23which means that problems in your teeth can be painful.
0:06:23 > 0:06:27But have you ever noticed that your teeth are different shapes?
0:06:27 > 0:06:30- Why is that?- Well, we're going to show you!
0:06:31 > 0:06:34Only an edible experiment can answer that question.
0:06:35 > 0:06:36Ta-da!
0:06:36 > 0:06:39- Why are you wearing that?- We need to have a good close-up look...
0:06:39 > 0:06:42What Xand is trying to say is that he's ready for the experiment and he
0:06:42 > 0:06:45wants to have a good, close-up look at the different shapes of teeth,
0:06:45 > 0:06:46so he's using a mouth stretcher.
0:06:46 > 0:06:50- That's what I said!- So let's have a look at the four different types of
0:06:50 > 0:06:53teeth in Xand's mouth, because they all do different jobs.
0:06:53 > 0:06:57At the front, we have incisors, four at the top and four at the bottom.
0:06:57 > 0:06:59Just behind the incisors, there are canines,
0:06:59 > 0:07:01and then just behind the canines,
0:07:01 > 0:07:06the premolars and just behind the premolars are the molars.
0:07:06 > 0:07:09But why do we need these four different types of teeth?
0:07:09 > 0:07:11Well, we're going to find out in...
0:07:11 > 0:07:14Our terrific tooth testing test!
0:07:14 > 0:07:18We're going to see what happens when we bite and chew different foods
0:07:18 > 0:07:21using our teeth, but not our normal teeth of different shapes.
0:07:21 > 0:07:23We're going to be using...
0:07:23 > 0:07:24These!
0:07:26 > 0:07:28We both have a custom made set of gnashers,
0:07:28 > 0:07:31but they're made up of only one type of tooth.
0:07:31 > 0:07:33Xand has a full set of molars,
0:07:35 > 0:07:38so he's Team Molar.
0:07:38 > 0:07:40Chris has a mouth of canines...
0:07:42 > 0:07:44so he's Team Canine.
0:07:44 > 0:07:48Our challenge is to bite into a range of food and chew it.
0:07:48 > 0:07:49Reveal the food.
0:07:49 > 0:07:51Then, rather than swallowing the food,
0:07:51 > 0:07:55we'll spit it out and see which type of tooth has worked best.
0:07:55 > 0:07:57First up, a sandwich.
0:07:59 > 0:08:01Mmm.
0:08:01 > 0:08:04With soft food, Team Molar chews brilliantly,
0:08:04 > 0:08:08whereas Team Canine can bite but definitely can't chew.
0:08:08 > 0:08:09What you can see there is
0:08:09 > 0:08:13a perfect bite of sandwich completely un-chewed.
0:08:14 > 0:08:16What about eating a hard apple?
0:08:16 > 0:08:19I can't get any. I can't get any apple.
0:08:19 > 0:08:24Team Molar is really bad at biting and team canine has a good bite,
0:08:24 > 0:08:25but can't chew it.
0:08:25 > 0:08:28You should give it to me and I can't chew it up for you.
0:08:28 > 0:08:31What, and then give it back to me and I could swallow it?
0:08:31 > 0:08:33No, that's disgusting.
0:08:33 > 0:08:35And it's the same story with a steak.
0:08:35 > 0:08:38I can tear it off easily, but then I can't chew it.
0:08:38 > 0:08:41Watch.
0:08:41 > 0:08:44Well, I can chew it, but I can't actually get a piece off.
0:08:44 > 0:08:47- You're just pulverising it. - So, who won that one, then, Chris?
0:08:47 > 0:08:50Well, I don't think either of us did very well, did we?
0:08:50 > 0:08:51What a disaster.
0:08:51 > 0:08:54It proved exactly what we wanted, Xand.
0:08:54 > 0:08:57Only having one shape of tooth makes eating impossible.
0:08:59 > 0:09:01You need your sharp, pointy canines at the front for biting
0:09:01 > 0:09:05and then your flat, wide molars at the back for mashing food up.
0:09:06 > 0:09:10So, we've shown you that the crowns of your teeth are covered in a hard
0:09:10 > 0:09:12layer called enamel and inside your teeth
0:09:12 > 0:09:16you have layers called dentine and pulp, which are packed with nerves.
0:09:16 > 0:09:20And we've shown you that you have four types of teeth for a very good
0:09:20 > 0:09:24reason. Different shaped teeth have different jobs and only by working
0:09:24 > 0:09:26together can you eat safely.
0:09:26 > 0:09:29Well, Chris, what better way to celebrate our teeth
0:09:29 > 0:09:31than with a brand-new profile picture?
0:09:32 > 0:09:34What do you think?
0:09:38 > 0:09:41Meet Caiden, Maisie, Bolu and Millie.
0:09:41 > 0:09:43We are following them across the series
0:09:43 > 0:09:45as they let us know what it's like
0:09:45 > 0:09:47to be a regular hospital outpatient.
0:09:47 > 0:09:51They're inviting us into their lives at home and as they undergo
0:09:51 > 0:09:54treatment. We're catching up with 11-year-old Maisie.
0:09:54 > 0:09:59- Hello.- She has coeliac disease, which means she can't eat gluten,
0:09:59 > 0:10:02found in wheat, barley and rye.
0:10:02 > 0:10:05So I'm going to make myself my lunch for school.
0:10:05 > 0:10:09I have some brownie which I made last night, gluten-free,
0:10:09 > 0:10:13and I'm going to have some home-made gluten-free chicken nuggets
0:10:13 > 0:10:14that my mum did last night.
0:10:14 > 0:10:21I'll have a fruit salad and some cucumber and a bag of crisps as well
0:10:21 > 0:10:23and these are really good because
0:10:23 > 0:10:26they have the gluten-free symbol on them.
0:10:26 > 0:10:29Maisie's lunch is often different to her school friends because many
0:10:29 > 0:10:31things they eat contain gluten.
0:10:31 > 0:10:33So here's what Jess has got.
0:10:33 > 0:10:37She's got some crisps which I wouldn't be able to eat.
0:10:37 > 0:10:38This foil had a sandwich in it
0:10:38 > 0:10:41and I couldn't have had it because bread is
0:10:41 > 0:10:44not naturally gluten-free because it has flour in it,
0:10:44 > 0:10:47which has wheat in it, which would make me really ill,
0:10:47 > 0:10:50so all I would have been able to eat out of this lunch would have been
0:10:50 > 0:10:53the banana.
0:10:53 > 0:10:55It's important Maisie eats the correct food
0:10:55 > 0:10:57so her body can extract energy
0:10:57 > 0:10:58from it like the rest of her class.
0:10:58 > 0:11:01So we've just eaten our lunch,
0:11:01 > 0:11:04we've come outside to play a big game of netball.
0:11:04 > 0:11:06Now, if I had have eaten something with gluten in my lunch,
0:11:06 > 0:11:09then I wouldn't have been able to do this and I would have been stuck
0:11:09 > 0:11:12inside and probably waiting for my mum to come and pick me up to take
0:11:12 > 0:11:14me home so I could get back in bed,
0:11:14 > 0:11:15cos I wouldn't be feeling well at all.
0:11:15 > 0:11:20Find out how Maisie gets on next time when she visits her dietician.
0:11:20 > 0:11:22Thanks for coming and visiting me in my school.
0:11:22 > 0:11:24- Bye!- Bye!
0:11:28 > 0:11:30Remember Will with his sore knee?
0:11:30 > 0:11:33- No.- Will, with the sore knee.
0:11:33 > 0:11:36- No, I don't think so. - You just met him.
0:11:36 > 0:11:38Oh, you mean Sore Knee Will?
0:11:38 > 0:11:41With his sore knee? Down in the sore knee department?
0:11:41 > 0:11:43- Let's find out how he's getting on. - Why didn't you say so?
0:11:45 > 0:11:46Earlier in the emergency department,
0:11:46 > 0:11:49Will came in with his left leg in limbo.
0:11:49 > 0:11:51Yes, that's him, Sore Knee Will.
0:11:51 > 0:11:53Shh, Xand. What did the doctor say?
0:11:53 > 0:11:56They said it was a broken patella.
0:11:56 > 0:11:59Will was competing in the British motocross youth championships.
0:11:59 > 0:12:03He fell off his bike and bashed his knee on a rock.
0:12:03 > 0:12:07Ouch! Doctors thought Will might have broken his patella -
0:12:07 > 0:12:08or kneecap -
0:12:08 > 0:12:11so he was sent to see an orthopaedic doctor who specialises in bones.
0:12:11 > 0:12:13Point to where that's hurting.
0:12:13 > 0:12:15Here.
0:12:16 > 0:12:20Radiographer Andrew takes X-rays from different angles
0:12:20 > 0:12:23to help Dr Janet find the cause of Will's pain.
0:12:23 > 0:12:25That's lovely. OK, all finished now.
0:12:25 > 0:12:27Now it's time for the results.
0:12:27 > 0:12:31What I can see on the X-ray is that you've got lots of soft tissue
0:12:31 > 0:12:36swelling around here and you haven't got anything that suggests that
0:12:36 > 0:12:38you've got a broken bone inside the knee.
0:12:38 > 0:12:40No break is good news,
0:12:40 > 0:12:44but a soft tissue injury can take just as long to heal.
0:12:44 > 0:12:46A soft tissue injury can involve damage to muscles,
0:12:46 > 0:12:49ligaments and tendons around the bone.
0:12:49 > 0:12:53They usually come from a sprain, strain or a whack to the skin,
0:12:53 > 0:12:55like Will got to his knee.
0:12:55 > 0:12:59It can swell, bruise and be really painful.
0:12:59 > 0:13:00So what's the plan, Doc?
0:13:00 > 0:13:02So what we're going to do with you is,
0:13:02 > 0:13:05we're going to put you in something called a range of movement brace.
0:13:05 > 0:13:08It will protect your leg and will protect your knee.
0:13:08 > 0:13:10Great news.
0:13:10 > 0:13:13So, Will heads off for his special leg brace.
0:13:13 > 0:13:16It will allow him some of movement, but with support.
0:13:16 > 0:13:18Can I get you just to pop your fingers there for me?
0:13:18 > 0:13:21This will encourage his muscles to heal without further damage to the
0:13:21 > 0:13:24- injury.- So you'll find that when you start moving your leg,
0:13:24 > 0:13:25your knee will actually bend a little bit,
0:13:25 > 0:13:29but it will stop at certain points, it's not going to keep bending.
0:13:29 > 0:13:32All fixed up. What have you learned, fella?
0:13:32 > 0:13:36I've learnt to not go as fast around corners,
0:13:36 > 0:13:38keep it nice and smooth with the bike.
0:13:38 > 0:13:40Sounds like a plan.
0:13:40 > 0:13:41- Take care.- Bye.
0:13:41 > 0:13:42Bye!
0:13:45 > 0:13:47Still to come...
0:13:47 > 0:13:49Ouch patient Kaden has his checkup.
0:13:49 > 0:13:52Now we're just getting all my medication.
0:13:52 > 0:13:54And Chris takes to the skies. Well, sort of.
0:13:54 > 0:13:58I completely forgot that we weren't in the air.
0:13:58 > 0:14:03- But now...- Amazing people do lots of important jobs inside and outside
0:14:03 > 0:14:06hospitals that help to keep you safe.
0:14:06 > 0:14:08But what will happen when we have a go?
0:14:08 > 0:14:10I feel a bit silly.
0:14:10 > 0:14:13This is...
0:14:13 > 0:14:15Can you guess who today's hero is? Well, I'll give you a clue.
0:14:15 > 0:14:18They might save you if you're wearing one of these...
0:14:19 > 0:14:21And these...
0:14:21 > 0:14:23..and some of these.
0:14:23 > 0:14:25Aaargh!
0:14:25 > 0:14:28Well, it's lucky I was wearing my swimming trunks today.
0:14:29 > 0:14:33Did you guess it? We're about to take over the job of today's hero,
0:14:33 > 0:14:36lifeguard Donna.
0:14:36 > 0:14:40Being a lifeguard isn't just about watching out for rule breakers like
0:14:40 > 0:14:43Xand, it's about saving lives.
0:14:43 > 0:14:45Donna's a lifeguard training manager,
0:14:45 > 0:14:47so she's an expert in spotting swimmers in trouble
0:14:47 > 0:14:51and giving medical attention for all sorts of injuries.
0:14:51 > 0:14:53Common things are nosebleeds.
0:14:53 > 0:14:55People run down the side of the pool, slip over.
0:14:55 > 0:14:58We might have people that can't really swim very well,
0:14:58 > 0:15:00so we might have to do minor rescues.
0:15:00 > 0:15:03We might have some older swimmers that might have heart conditions.
0:15:03 > 0:15:06We go right from the very mundane to the life-threatening and serious.
0:15:06 > 0:15:09So we're going to be lifeguards later.
0:15:09 > 0:15:10What do we need to know?
0:15:10 > 0:15:12So a big one is communicating.
0:15:12 > 0:15:13We'd use the whistle.
0:15:15 > 0:15:18One short whistle blast gets the attention of a bather.
0:15:19 > 0:15:22Two short whistle blasts...
0:15:22 > 0:15:24I need to talk to another member of my lifeguard team,
0:15:24 > 0:15:26get their attention for something in the pool.
0:15:26 > 0:15:28And then three short whistle blasts...
0:15:29 > 0:15:31..I might need to go in and do a rescue
0:15:31 > 0:15:33and I need to tell everybody that's where I'm going.
0:15:33 > 0:15:34Can I have a green whistle?
0:15:34 > 0:15:36If you like, yes.
0:15:36 > 0:15:38Thank goodness for that.
0:15:38 > 0:15:42Next step, use a really high chair to get a brilliant view.
0:15:42 > 0:15:44The lifeguards are constantly watching the pool.
0:15:44 > 0:15:47We use scanning patterns as well, so we might do a side to side motion,
0:15:47 > 0:15:49we might do up and down the pool.
0:15:49 > 0:15:51They're constantly changing the way they're doing things
0:15:51 > 0:15:53to keep themselves aware.
0:15:53 > 0:15:55And finally, for more serious cases,
0:15:55 > 0:15:57use the really important rescue board
0:15:57 > 0:16:00to help get casualties out of the water safely.
0:16:00 > 0:16:02We're really worried more about spinal injury,
0:16:02 > 0:16:03so by having them on board,
0:16:03 > 0:16:05we've got them supported and we can strap them
0:16:05 > 0:16:06so they don't move any more,
0:16:06 > 0:16:09we're not going to make that injury any worse.
0:16:09 > 0:16:11The lifeguards secure the straps gently, but tightly,
0:16:11 > 0:16:14around the casualty to prevent causing more injury.
0:16:14 > 0:16:17Thanks, Donna. There's a lot to remember.
0:16:17 > 0:16:19We've seen how important the lifeguards are
0:16:19 > 0:16:21at keeping us safe while we're swimming
0:16:21 > 0:16:23and how they respond to emergencies.
0:16:23 > 0:16:27But how will Chris and I do when we're thrown in the deep end?
0:16:27 > 0:16:28Get it? Get it?
0:16:29 > 0:16:32It's time for us to take over as lifeguards.
0:16:36 > 0:16:40Our challenge is to spot if someone's in danger,
0:16:40 > 0:16:44use the correct whistle signals to alert the other lifeguards to help.
0:16:44 > 0:16:46And use the rescue board to get a swimmer
0:16:46 > 0:16:47with a suspected spinal injury
0:16:47 > 0:16:50out of the water quickly and safely.
0:16:50 > 0:16:53Xand, have you got a handle on the different whistle signals?
0:16:53 > 0:16:55Go on, test me. Test me.
0:16:56 > 0:17:00- It's lunchtime! - This could be embarrassing.
0:17:00 > 0:17:03With extra poolside lifeguards on hand to keep swimmers safe,
0:17:03 > 0:17:06Donna will be judging our every move and picking a winner.
0:17:06 > 0:17:08Chris, you're up first.
0:17:10 > 0:17:13Lifeguard Keiran is pretending to be an injured swimmer.
0:17:14 > 0:17:16Will Chris spot him?
0:17:19 > 0:17:20WHISTLE BLOWS THREE TIMES
0:17:20 > 0:17:23He got the right number of whistles on that one.
0:17:23 > 0:17:26Three whistles means he's on his way in.
0:17:27 > 0:17:30What are you doing now, Chris?
0:17:30 > 0:17:32So I almost strapped Sam to the board.
0:17:32 > 0:17:35Sam's just one of the lifeguards helping, not the patient.
0:17:35 > 0:17:37Sorry, Sam.
0:17:37 > 0:17:39Oh, beginner's error, eh, Donna?
0:17:39 > 0:17:42- Head strap's a little bit slow. - Uh-oh. Quicker, Chris!
0:17:42 > 0:17:44He's not doing too well at the moment.
0:17:44 > 0:17:47Oh, dear. You need a strong finish here, Chris.
0:17:47 > 0:17:50- What do you think, Donna? - He's a little bit on the loose side.
0:17:50 > 0:17:52- A bit loose, really?- A bit loose.
0:17:52 > 0:17:54- These are really loose.- Oh, really?
0:17:54 > 0:17:56Well, that's not good. Time to move aside, Chris,
0:17:56 > 0:17:58and watch how the master does it.
0:17:58 > 0:18:00Yeah, right! Your turn.
0:18:01 > 0:18:03Here comes our fake casualty.
0:18:06 > 0:18:08Have you seen him, Xand?
0:18:09 > 0:18:11Xand?
0:18:11 > 0:18:13Xand!
0:18:13 > 0:18:14Oh, oh, oh...
0:18:14 > 0:18:16WHISTLE BLOWS TWICE
0:18:16 > 0:18:18Two whistles to get the other lifeguards' attention...
0:18:18 > 0:18:20He's given the right signal.
0:18:20 > 0:18:22..and another three to say he's on his way.
0:18:22 > 0:18:24He's run right past the board!
0:18:24 > 0:18:27- Oh, Xand!- That's not good.
0:18:27 > 0:18:29He's quickly got the chest strap on
0:18:29 > 0:18:32and now he's going for the head strap.
0:18:32 > 0:18:35Really jerking those straps into place now.
0:18:35 > 0:18:37Whoa, there. Careful.
0:18:37 > 0:18:40- Oh.- This is going to be a tight contest.
0:18:40 > 0:18:42Time to see who came out on top.
0:18:45 > 0:18:46A few things from both of you.
0:18:46 > 0:18:48Chris, you started off really well.
0:18:48 > 0:18:51It all fell apart a little bit when you got the board in, though.
0:18:51 > 0:18:53And then when we lifted out, the straps were quite loose.
0:18:53 > 0:18:56But, Xand, it was a little bit the other way around for you.
0:18:56 > 0:18:59The guy was face down in the water for quite a while
0:18:59 > 0:19:00before you reacted.
0:19:00 > 0:19:03You ran right past the board and had to come back for it,
0:19:03 > 0:19:06but putting it in didn't go too badly.
0:19:06 > 0:19:09So your verdict for today, guys...
0:19:09 > 0:19:11..it's a draw.
0:19:11 > 0:19:15- A draw? - We were both equally amazing.
0:19:15 > 0:19:18Yes, or equally rubbish.
0:19:18 > 0:19:20We learned a lot today, but I would say that, overall, Donna,
0:19:20 > 0:19:23it is best if we leave it to the experts.
0:19:23 > 0:19:25Xand, let's hand our whistles back.
0:19:32 > 0:19:34Hi, I'm Kaden.
0:19:34 > 0:19:38Last time, we met ten-year-old Kaden, who has cystic fibrosis.
0:19:38 > 0:19:42Cystic fibrosis is something that affects your lungs.
0:19:42 > 0:19:45His lungs produce a thick, sticky mucus,
0:19:45 > 0:19:47which can make it hard to breathe and lead to infections.
0:19:49 > 0:19:52Kaden has regular visits to Sheffield Children's Hospital
0:19:52 > 0:19:53to check on his condition.
0:19:53 > 0:19:57I'm about to get my checkup that I have every six weeks.
0:19:57 > 0:19:59First up, he has a spirometry test
0:19:59 > 0:20:02to measure how his lungs are functioning.
0:20:02 > 0:20:05This machine, like, counts my blows
0:20:05 > 0:20:09to see if I can breathe properly and all of that.
0:20:09 > 0:20:11Well done.
0:20:11 > 0:20:14Kaden has something called a port under his armpit.
0:20:14 > 0:20:18A port is like a little socket that goes under the skin with a tube
0:20:18 > 0:20:20that leads directly into Kaden's blood vessels.
0:20:20 > 0:20:24The port is to make it easier so that they don't have to stick
0:20:24 > 0:20:28needles in my arm or in my hand, or anywhere else.
0:20:28 > 0:20:30So doctors can insert Kaden's antibiotics
0:20:30 > 0:20:34directly into his veins without him having lots of injections.
0:20:34 > 0:20:38It's really important that the port is kept clean, so today,
0:20:38 > 0:20:40he's having it flushed out with saline.
0:20:40 > 0:20:44It's a bit cold and it feels a bit weird, but it's all fine now.
0:20:45 > 0:20:48- See you in six weeks. - Bye-bye!
0:20:48 > 0:20:51There's one more stop for Kaden before he goes home.
0:20:51 > 0:20:53Now we're just getting all my medication.
0:20:53 > 0:20:55Wow, two bags full of medicine.
0:20:55 > 0:20:58Yup, but all of this is to help clear Kaden's lungs
0:20:58 > 0:21:00and treat his condition.
0:21:00 > 0:21:01Bye, see you next time.
0:21:05 > 0:21:08Today, I'm getting on a plane, but not just any old plane.
0:21:08 > 0:21:11I... What are you doing?
0:21:11 > 0:21:14Well, you're not going on holiday without me and Mr Grumbles.
0:21:14 > 0:21:16We've been looking forward to a little time in the sun.
0:21:16 > 0:21:18Xand, we are not going on holiday.
0:21:20 > 0:21:22I am getting on a special kind of plane,
0:21:22 > 0:21:25- one that turns into a hospital. - Oh, I see.
0:21:27 > 0:21:30This is awkward. Will you be needing this?
0:21:30 > 0:21:32No, I won't, Xand.
0:21:32 > 0:21:34It's time for Investigation Ouch!
0:21:37 > 0:21:42Today, I'm at RAF Brize Norton, the largest RAF station in the UK,
0:21:42 > 0:21:45home to the RAF's tactical medical wing.
0:21:45 > 0:21:48Meet the flight medical team.
0:21:48 > 0:21:51And Sergeant Chris is part of this heroic crew.
0:21:51 > 0:21:54Chris, what is the tactical medical wing?
0:21:54 > 0:21:56So, the tactical medical wing will provide medical support
0:21:56 > 0:21:59to personnel all around the world.
0:21:59 > 0:22:01This kind of medical care is really complex.
0:22:01 > 0:22:03How do you train for it?
0:22:03 > 0:22:05So we'll do a practical scenario on board a real aircraft,
0:22:05 > 0:22:08- like we're going to do today. - Can I have a look?
0:22:08 > 0:22:10- Absolutely.- Fantastic.
0:22:10 > 0:22:12This is the C-17.
0:22:12 > 0:22:15At about 53 metres long and wide,
0:22:15 > 0:22:18it's almost twice the size of a blue whale.
0:22:18 > 0:22:21This plane not only needs to carry everything from tanks
0:22:21 > 0:22:24to helicopters, troops to supplies,
0:22:24 > 0:22:27amazingly, it also doubles up as a hospital.
0:22:27 > 0:22:30So you can see behind me they're building the stretcher stanchions
0:22:30 > 0:22:31to act almost as bunks for patients,
0:22:31 > 0:22:34but the remarkable thing is that it can support
0:22:34 > 0:22:36the most severely injured patients of all,
0:22:36 > 0:22:38people who need life-support.
0:22:38 > 0:22:43It only takes ten minutes to turn this plane into a hospital.
0:22:48 > 0:22:51We're in Nepal. It might not look much like Nepal,
0:22:51 > 0:22:53but that's where today's scenario is taking place.
0:22:53 > 0:22:56So some military personnel were on an expedition,
0:22:56 > 0:23:00there's been an earthquake and they have different levels of injury and
0:23:00 > 0:23:03they're being treated to get them ready and fit to fly.
0:23:03 > 0:23:06This casualty has two broken legs,
0:23:06 > 0:23:08but there are other patients with even more serious injuries
0:23:08 > 0:23:11and they're whisked away to the plane.
0:23:11 > 0:23:14So Mary's had a head injury she got in the earthquake,
0:23:14 > 0:23:17and so she is now fully stabilised.
0:23:17 > 0:23:20She's got a neck brace on to keep her spine stable
0:23:20 > 0:23:22and she's got an oxygen mask.
0:23:22 > 0:23:24And the team are now putting on monitors
0:23:24 > 0:23:27so that she can be cared for in exactly the same way
0:23:27 > 0:23:30that she would be in a big hospital in the UK.
0:23:30 > 0:23:32It is totally remarkable.
0:23:33 > 0:23:35If this was a real situation,
0:23:35 > 0:23:37we'd now take off and head home with the casualties.
0:23:38 > 0:23:41So unlike the kind of aircraft that you may have been on,
0:23:41 > 0:23:44all the seats are along the side
0:23:44 > 0:23:46and that creates space in the middle
0:23:46 > 0:23:48either for cargo or for patients.
0:23:48 > 0:23:49We are now at maximum altitude.
0:23:49 > 0:23:51You can go along with your business.
0:23:51 > 0:23:54During the flight, the medics keep the patient stable and safe.
0:23:54 > 0:23:57So, because Mary's got a head injury and she may have other severe
0:23:57 > 0:24:01injuries, the team have put her in this amazing vacuum mattress,
0:24:01 > 0:24:04which is full of little polystyrene balls.
0:24:04 > 0:24:07They've sucked the air out of it and now this is squeezing her and partly
0:24:07 > 0:24:11it protects her from the effects of being in a bumpy aeroplane.
0:24:11 > 0:24:12It will make her more comfortable
0:24:12 > 0:24:15and make her injuries less likely to get worse.
0:24:15 > 0:24:17How are you feeling, Mary?
0:24:17 > 0:24:19- I'm all right.- You're all right?
0:24:19 > 0:24:22It's amazing that patients can be treated exactly as if they were in
0:24:22 > 0:24:26hospital, except they're thousands of feet up in the air.
0:24:26 > 0:24:28Training like this is fantastically important
0:24:28 > 0:24:31for getting things right in a real emergency
0:24:31 > 0:24:34and these guys have done such a good job that I basically
0:24:34 > 0:24:37completely forgot that we weren't in the air until I look out the window.
0:24:39 > 0:24:41Yup, that's definitely not Nepal.
0:24:44 > 0:24:46Let's head back to the emergency department.
0:24:46 > 0:24:48It's time for the next patient.
0:24:48 > 0:24:50Well, come on, Chris, what are you waiting for?!
0:24:53 > 0:24:55Over in the emergency department,
0:24:55 > 0:24:5911-year-old Lily and her mum are looking rather...happy.
0:24:59 > 0:25:00What's happened, Lily?
0:25:00 > 0:25:04I fell on my hand and it really, really hurts now.
0:25:04 > 0:25:06It is a bit of a mystery, to be honest.
0:25:06 > 0:25:10A mystery? Well, panic not, Lily, Inspector Xand's on the case.
0:25:12 > 0:25:14It all began two weeks ago.
0:25:14 > 0:25:17Meet suspect A, the bed.
0:25:17 > 0:25:18Lily woke up in her bedroom
0:25:18 > 0:25:22and managed to tumble straight off the side, landing on her wrist.
0:25:22 > 0:25:25- Ouch!- Shush, Chris. This isn't over yet.
0:25:25 > 0:25:26Righty-ho.
0:25:26 > 0:25:3114 days later, enter suspect B, the dance class.
0:25:31 > 0:25:32I knew it!
0:25:32 > 0:25:35Lily was doing a handstand in school when her wrist buckled
0:25:35 > 0:25:38underneath her and she fell over.
0:25:38 > 0:25:41- Double ouch!- You're very clumsy, aren't you?
0:25:41 > 0:25:43I fall over a lot.
0:25:43 > 0:25:46Mystery solved! Lily's accident prone.
0:25:47 > 0:25:51Let's get Doctor Suhail Habib to check out her wrist.
0:25:52 > 0:25:54- That hurts.- It hurts here?
0:25:54 > 0:25:58So there is a bit of bruise there and there's mild swelling.
0:25:58 > 0:26:01The only way we can find out whether it's fractured or not
0:26:01 > 0:26:03- is to get an X-ray. - I've had them before.
0:26:03 > 0:26:05Oh, you've had them before?
0:26:05 > 0:26:09Yeah, I've had one on them two fingers and one on them two fingers.
0:26:09 > 0:26:11Crikey, Lily, have you broken anywhere else?
0:26:11 > 0:26:13- My toe.- I see.
0:26:13 > 0:26:16And then I ended up putting a pork chop on it as well.
0:26:16 > 0:26:21- Pork chop?- We didn't have no ice or no peas, so we used a pork chop.
0:26:21 > 0:26:22Yeah, that were a good one, weren't it?
0:26:22 > 0:26:24That were a really good one.
0:26:24 > 0:26:27There are 29 bones to check in the X-ray.
0:26:27 > 0:26:30Two big bones in your lower arm, the radius and the ulna.
0:26:30 > 0:26:33Eight bones in your wrist called the carpals.
0:26:33 > 0:26:35Five metacarpals in the back of your hand

0:26:43 > 0:26:45- What do you reckon, Lily?- Broken?
0:26:45 > 0:26:47- Mum?- I think it's not broken.
0:26:47 > 0:26:49Mum has won.
0:26:50 > 0:26:53So it's not broken, which is good news, yeah.
0:26:53 > 0:26:55But that doesn't mean that there's no injury,
0:26:55 > 0:26:59so you have got some injury to the soft tissues.

0:27:34 > 0:27:36Oh, no, have we missed the end?
0:27:38 > 0:27:39I thought so.

0:27:46 > 0:27:48would you mind having a look at mine?
0:27:48 > 0:27:49I've got a real problem with them.
