Brilliant video. Thanks so much. I have a question tho, there seems to be a contradiction around 12:37. It first says that the third reason is that more Nitrogen than Oxigen can be disolved into the blood without saturation, and then it continues saying that twice as much OXIGEN can disolve without causing any problems. Is this contradictory or am I interpreting it incorrectly?
1:32 the pressure gradient of nitrogen is not the problem, otherwise you would get bent by switching to pure oxygen at the bottom. The problem is supersaturation, which is not the same thing as gradient.
Thanks. Now my question is it in normal place we r breathing as well nitrogen gas as in my home, outside the home etc what about high altitude place like Mt Everest?
Yes, it's in your home, out in the forest, etc. Air is about 79% nitrogen and 21% oxygen. (I say "about" because there is a small amount of other gases like argon, carbon dioxide, etc. in the air, too.) It's not altitude dependent; as you go higher, the density of all gases decreases, but the percentages stay the same.
It's too technical - you're gonna lose people because it's boring! Use diagrams and simple gas expansion theory... People lose interest when you start talking about platelets & PFOs .... I had a DCS Type 1 whilst working as a diving instructor in Thailand and it wasn't the end of the world - many instructors take a bend during CESAs etc and it is just a hazard of the job! Please stop this scare mongering - it has nothing to do with reality!!
Presenting facts is not "scare mongering," it's called "education." If learning about the causes of DCS scares you, you should stop diving and you certainly shouldn't be instructing. Your potential students deserve better.
@@JustinColman-kz5fl I'm not a diver, and I know this disease is uncommon in recreational divers, and in the rare cases where it happens its very mild. But if you're instructing people to dive deep, and there's a bigger risk involved, they should know how bad things can go if they dont follow the rules. Just so that they don't take things lightly.
Great explanation for non-divers who are forever and firmly going to remain non-divers 😄
Yep lol
Hahaha!
same
fr i might quit diving alltogether, chance i got DCS type 2
Damn, Rest In Peace Julia 😪
Man of Medan anyone?
Me 2
Me
Me
Yes lol
I thought it was only me hahahah
Finally someone who explained this properly. Thanks!
Man of Medan research squaaad

JoeBailey23 Alex made decompressing sound important so I looked it up
Wtf hahahaha
Yesssirr
Fts I ain’t ever diving more than 8 feet.
This was a really fantastic explanation thank you
very explicative video, simple but accurate. Bravo!
Brilliant video. Thanks so much.

Thank you.
.... painfully slow presentation
Have you ever heard of the playback speed option??
This is stuff you wanna learn slowly so you can fully process each word. After all your life could depend on it.
Brilliant, thanks for this
then why do they use nitrogen at all in the oxygen cylinders? Wouldn't it be better to not use it at all?
Great video!
I had problems sleeping. And, I don't think it's gonna be a problem now...
I came here after watching 47 metres down
Thank you
Really helpful. thanks
Where is the nitrogen coming from under water? Isn't it pure oxygen in the tubes they carry?
No, the cylinder is 21% oxygen and 79% Nitrogen
came here after seeing that Israeli diver video. seemed like DCS hit him pretty quickly
Lipski?
Dam decomposition illness is no joke

Great video, but I would be opening a can of Pepsi.
Coke not poopsi!

wow i dont swim or understand this phenomenon 1000 ways to die brought me here
Is this a french guy speaking?
Decompression for dummies. Well done. Chapeau.
Good Job Guys :)
I have been forever banned from diving due to my asthma.
Is that deeper diving or even excluded from just a few meters. Say 10 to 15 feet? (Try Dive depth) I ask because my 19 year old son is also afflicted.
Can you get this spearfishing
House M.D. led me here.
Now I feel like I don't wanna be a space man anymore 👁️👄👁️

People have lost their lives to this disease. You got lucky. Tell that to whoever you're instructing.
@@omarshahin3288 I'm aware of that, obviously but this is of no interest to the casual observer. Also. it's not exactly enticing for future divers.

@@omarshahin3288 Don't worry Omar, if you're not a diver, then it's nothing you need to worry yourself about.... It's covered.
