Where to buy or get (depends on licensing) Beyond Blue documentary?

[armandin2048]

Whart is a "narcotic iffict"??? (20 seconds)

[anormaluser]

@armandin2048 narcotic effect....its like u become drunk all of a sudden, and its caused by nitrogen.

[armandin2048]

@anormaluser You must be a Kiwi as well if you understood that LOL

[anormaluser]

@armandin2048 hahaha nah buddy im spanish.

[SIMFISHING]

@armandin2048 maybe she said :narcotic effect. ??

[Phar2Rekliss]

watch the film "SPHERE" and you will understand more about deep sea diving and why Helium is used.

[tek5828]

Don't you mean 318.25m not 31825m (thirty one thousand eight hundred and twenty five)

[TheHandsomeCrab]

So does Helium like dissolve in the blood stream past certain depths?

[machacoification]

we don't really understand what you are saying, I ll take it that you are reading and don't know what you are talking about,,, just because you can read fast doesn't necessary means PEOPLE think you are clever or something, perhaps you may consider of spitting out pubic hair before reading again... terrible accent though

[isfunnycuzistrue]

i once hooked a diver while fishing for trouts.. :/

[Asartex]

她說什麼 ? 

[machacoification]

@Asartex totally right you too, whatever that means

[boldziga]

I hate that accent

[a10fjet]

Woah, i somehow understood her. But i think i need to lay off the weed, i could swear that yellow line was curving...

[ryno2085]

I love a South African accent

[97Arran]

Im curious, could you use a trimix with 21% o2 and then a nitrogen, helium mix and do a recreational dive to 40m ? Any advice would be good

Thanks

[NOWDIVE]

@97Arran, Yes a Tmx of 21/35 would be a nice mix. But why not get som extra time... and make it a 28/35. This way you optimize the O2 and reduce the narcosis with the He. The 28/35 gives you a END equivilent narcotic depth of: 23 meter END= ((1-F.He)x(D+10)-10) So 1-,035= 0,65 x 50 -10 = 22,5 meters. You will learns this on a TEK course.

[btownmxer]

Imagine what she would sound like if I was puttin 9 inches down her birth canal

[zxcvbnmjfjf]

cool i didn't even know there where other breathable compounds like diferent forms, they should go into more detail because i find this very interesting, btw i understood you/commentator perfectly :D

[tjenk712]

Wow, can I get shot into outer space without a spacesuit?  What does all this prove?

0:17 on that page,look for something that looks dirty.

[UCDEamon]

It's He not He2. Helium is a noble gas.

[Soldier334]

@UCDEamon That's correct but it might be a different mixture then just pure Helium

[AtomicCactus]

Since when was helium a diatomic gas? Cute :-).

[kondadotm]

terrible accent

[jacoherbst]

@kondadotm says he who is cowardly leaving a comment using a unidentifiable username. Would love to hear your accent. SKYPE me at this username of mine.BTW it's my real name.

[NapanTR]

tks nice video

[syncstation]

shit there's no way i could get to 60 on just air! i struggle at 40!

[RFprogramator]

@syncstation you can go up to 67m with air. 1,6bar PPo2

[barbacan25]

i agree with ManOfMeans

[Kokoda144]

awsome vid!

[ManOfMeans]

Use a submarine, dammit!

[RubInatube]

lol!!

[zizikelizike]

its understandable...

[danielfu79]

I don't understand her... that accent!

[TheFATutorials]

@danielfu79 i understand that and im from germany!

[raziel422]

Very informative and interesting

[dhstandard22]

how would using all 3 of them protect himself?

[helraizer]

Oxygen at depths of around 60 metres becomes toxic, Nitrogen around 40 - 50 metres (depending on the person) becomes narcotic so there are less of them and helium will only be hazardous at very low depths causing the shakes, as she said.

I believe Nitrogen swells tissues around the nerves causing a loss in function (cognitive and motor); Helium does the opposite and shrinks the tissue which can cause them to fire 'randomly' causing the shakes. Both cancel eachother out (to an extent!)

[Samurailord]

there would also be the possibility to dive with hydrogen mixtures wich would allow for bigger depths with less Sideeffects.

BUT hydrogen and oxygen become highly explosive.. the security measures would've been enourmous and probably unaffordable :)

[Kynokeh]

you can't understand what she's saying.. where is she from?

[overseasmedia]

Kynokeh: From South Africa (watch my "Beyond Blue" documentary)

[erikborgersen]

@overseasmedia  Hi, where can I find this documentary ?

Thx a lot / Erik

[ShowALeitao]

@Kynokeh From the kitchen

shoisuhgojdnocmg ngovonuhc nigloiut jfkgjri oopopopop pooop poop poop poop poop poop jwugj it sounded llike she said penis!

[Christoo92]

why would pure Oxygen poison him?

[overseasmedia]

Christoo92: because at depth O2 has a narcotic and poisoning effect on human body

[Christoo92]

that's interesting!

Do you know how exactly it would poison someone?

[overseasmedia]

Christoo92: Sure! That's all described in the theory of technical diving (try TDI manuals)

[laxdude1119]

When the partial pressure of Oxygen reaches 1.6 bar or higher, a diver gets what is commonly known as CNS (Central Nervous System) Toxicity, usually resulting in death.

[carbontown]

Actually CNS Tox will not in itself kill you. You will get VINTED and then the cramps start. after that the reg will fall out of your mouth and you will drown....... Anyway Dead is Dead....

[laxdude1119]

Yes. I didn't say it would kill you, i said it usually results in death.

[carbontown]

Sorry about that mate but as a diving Instr. I really am picky on how words are used on that subject and the emphasise was on CNS and Death. Just had to clear that one up and point out that CNS will not, in itself, kill anyone its the effects that CNS brings about that WILL kill you......Anyway as I said DEAD is DEAD !!

[iRobert1771]

Do EAD secialization or read book by Nick Lane "Oxygen: The Molecule that made the World" (very interesting book).

Why are you asking? It's just biology.

[m91arc]

strange accent

[overseasmedia]

m91arc: South African!

[Kahuna76]

I'm not a tech diver, but don't they use Heliox (just O2 and helium without the nitrogen) at depths like that or do you need a rebreather for stuff like that?

[overseasmedia]

Kahuna76: I believe they use heliox or helitrox for much shallower dives. Helium cause so called (HPNS) high pressure nervous system syndrom when you body shakes uncontrollably. So Nuno used trimix for his deep dive he still talks a lot in the film about HPNS syndrom that he had at that depth.

[nuno32181]

At these depths one needs a bit of Nitrogen to try and decrease HPNS. Most of the mixture is Helium with some Oxygen and some Nitrogen. Heliox will not work so deep

[scubazmei]

Yes, the video is very informative, I agree!

[ShiznetShooner]

hu cares about the mistake, its minor

[deighton2002]

hi, very informative videos, but Helium is He not He2, two hydrogen atoms can't join together in the way hydrogen oxygen or nitrogen do.

[vidmaster75]

dightin2002: Hi there! Thanks a lot for noticing it, the guys who made the graphics obviously made amistake. Ahhhggrrr! Of coyrse it's He, not He2... I'll make them correct the mistake, thank you very much once again!

[overseasmedia]

deighton2002: Hi there, as you can see we corrected He, thanks once again for the comment!
