Decompression Sickness

A video lesson. Excessive super saturation and gas seeds/micronuclei. Silent bubbles. Type I decompression sickness: pain only, skin and joints. Type II decompression sickness: dangerous pulmonary and cerebral symptoms.

Great explanation for non-divers who are forever and firmly going to remain non-divers 😄

[taylorcate]

Finally someone who explained this properly. Thanks!

This was a really fantastic explanation thank you

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?

[stefanomancosu]

very explicative video, simple but accurate. Bravo!

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.

Fts I ain’t ever diving more than 8 feet.

[AmandeepSingh-ybnp]

then why do they use nitrogen at all in the oxygen cylinders? Wouldn't it be better to not use it at all?

[metsq]

I came here after watching 47 metres down

[yediveren]

Where is the nitrogen coming from under water? Isn't it pure oxygen in the tubes they carry?

[deadpool]

I had problems sleeping. And, I don't think it's gonna be a problem now...

[lexluther]

wow i dont swim or understand this phenomenon 1000 ways to die brought me here

[RaciouS]

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?

[dadirtydawg]

Great video, but I would be opening a can of Pepsi.

[khnrav]

came here after seeing that Israeli diver video. seemed like DCS hit him pretty quickly

[mvanphilips]

Decompression for dummies. Well done. Chapeau.

I have been forever banned from diving due to my asthma.

Now I feel like I don't wanna be a space man anymore 👁️👄👁️

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!!
