This video was inspired because I often hear people ask about our "oxygen tanks." I thought it was worth explaining what most divers are actually breathing. And there isn't a really good video out there about Nitrox.
Thank you! Its something i hear a lot as well. Unfortunately, its the kind of misunderstanding that could be dangerous. In my area technical wreck diving is common and therefore seeing cylinders labeled "Oxygen" is also common. Learning how to read markings on tanks and analyze your own gas are important safety skills.
Mr. Jonathan, these explainer videos are extremely important. Not only it educates people but also entertains them. So I suggest you to make more videos like this and a million other things that we don't know about the oceans. 1) I understand your budget isn't big and these videos aren't heavy on you to make. 2) There are no or less like these on youtube.
Owww, didn't see a fish but learned a lot today. Thanks to Jacques Cousteau and the many divers that investigated, sometimes fatally, about decompression disease. Nice instruction Jonathan. No creepy mystery anymore, but clear boundary values for staying safe. Best regards for you and your team, and stay safe, also out of the water.
My dive instructor kept pestering me to get my nitrox license but I didn't want to take the test. I took like half of it on the boat and my parents finished and got theirs. I do regret not getting it because now I will have to get it sometime after covid. I have used nitrox though and I like it a lot better than the normal mixture. Great video!
Really enjoying the educational videos the only thing that would make them even better (for your global audience) is to include metric conversions more 🙂
Very nice explanation of Nitrox! Would love to see a follow up video on tech stuff like extended range nitrox or trimix. Might be tough to explain while dicouraging people to try it on their own without training. Maybe show some of the training involved like you did with cave diving? Thank you for the awesome video!
@@sameermohideen4913 i have a feeling a good amount of diving folk watch this chanel 😁. Also, no need to get lost in the weeds so to speak. I think a general explanation to the tune of "it lets you do cool stuff but takes lots of practice" would be pretty easy to understand.
I think the term 'bends' comes from the very first divers who worked in bells to build bridges. DCS was not known at the time and they just came up quickly every day. They could not stand up straight any more after the injuries to their spine that they recieved from repetetive diving. That's why they were called 'bent'
Best explanation I have heard for decompression sickness. This clears up an argument I had with someone about a free diver getting it. They thought it was not possible and I had just watched a documentary about the guy with the world record who got it. I was like I don't know what to tell you he got it so obviously it is possible.
This was awesome! I am going to show this to my high school students who were just asking me a lot of these questions about Scuba diving last week. This did such a better job explaining it than I did.
Great video on air mixtures, thank you! I'll be showing this to my physical science class. You do a nice job of explaining a lot of relevant ideas making it easy to understand!
With a few exceptions. He is most likely doing what we divers call a Safety Stop. We hang out at 15 feet for 3 minutes after every dive to give our bodies extra time to safely release nitrogen.
I've been sharing these videos with quite a few people. I wish the Twitter account was more updated but... I do understand that people/time might not allow for it. Quite a few followers were very engaged through that platform. PS - Thanks BlueWorld Team for helping me in April get through a rough patch until I went back to work mid August. I learned a lot from this Channel.
It depends if you are using a PO2 of 1.4 or 1.6. 1.4 is what PADI reccomends for recreational divers so i was kinda surprised at 32% --> 130 feet also. (P02 = partial pressure of Oxygen)
Yep! The chart is probably all 1.4ATA based numbers. 1.6ATA figures are more common in tec diving. Fun fact, the depth limit of pure O2 (20 feet) is also based 1.6 calculations. Thank you for the awesome discussion!
@@Saxatillis Yes 1.4 PO2 is generally considered safenfor any workload, while 1.6 is only considered safe during resting workload. Which is why 1.6 PO2 is considered acceptable on your decompression stops since you're generally calmly ascending, pausing, ascending, etc. This higher PO2 allows you to switch to higher O2 percentages soonest, accelerating your deco.
Helium is another gas sometimes used to offset nitrogen, for a completely different reason. Helium still becomes absorbed by your tissues and requires decompression, however, it does not cause the narcotic effect of nitrogen at depth (which we did not discuss in this video). This breathing gas (consisting of oxygen, nitrogen and helium) is called trimix, and that's a a video for another time!
Interesting. Does your body tell you when you have too much nitrogen built up? In other words, do you start feeling symptoms where you can tell yourself, "I'm going up too fast, better slow down"?
There are signs and symptoms for DCS/DCI(Decompression Sickness/Illness) but they are not always immediate. It might take some time after a dive to start feeling symptoms, so you might not feel the symptoms on the way up or even immediately after getting out of the water. Going up too fast not only puts you at risk of DCS/DCI but also Lung over-expansion injuries which are pretty much some of the most serious injuries a diver can face.
Not usually. You can sense pressure difference in your ear like in an air plane or long elavator. With practice divers can have a pretty good sense of their rate of ascension. However, it is always reccomended to watch your dive computer and make sure you are being as safe as possible.

Just received my EAN Certification this week. Great explanation of Nitrox!

by far the best explaination of nitrox i've heard
Thank you!

A lot of that information would go right over the head of non diving folk.
I’d totally watch it though.

We will do tri-mix next I guess.
I try to explain things so the average non-diving person can understand.
@@BlueWorldplus Thanks I would love a video on Heliox and Trimix
Thank you for being so straightforward with this video it is exactly what I needed to hear
Very very good explanation. Thank you.
Bro, you are like the Bill Nye of scuba and I love it!
Very well explained thanks
I learned more from this video than physics class i had last week.

Now i understand why blue world always has a clip of jonathan decompressing 😂
With a few exceptions. He is most likely doing what we divers call a Safety Stop. We hang out at 15 feet for 3 minutes after every dive to give our bodies extra time to safely release nitrogen.
Exactly. I try to avoid "obligated decompression" if possible. But it's not always possible.
This video has so much information🔥🔥 continue Johnathon and blue world crew!!
Waiting for the latest blue world episode !!!

Yeah we are active on Facebook and Instagram but not really twitter.
What an amazing explanation. You and your crew are very talented. Now I finally understand Nitrox. Thanks.
Great to hear!
Wow, super informative
Glad you liked it!
Amazing explanation!!!! Simple and easy!!!
Glad you liked it!
Interesting
Thanks for. The info that was confusing for me
Another awesome video Jon
Beautifully explained... 3:55 is😂
I've learned alot from this video because i have 12 years old and i started at 11 in diving and i went on a dive with nitrox and idk what nitrox do
I want learn more tricks about scuba gear
We have more episodes of Scuba 101 and Tech With Todd coming!
Meters conversion would help your video 🧠👍
You should do a video on Tri gas next!
I like tha idea!
first
Would Helium and oxygen ! Be available for use in Scuba ? I believe it’s sometimes used in real deep diving!
We have a video about that. It's called Trimix.
Saw the videos great stuff ! Thanks again 😉
Nice video.
What if we get the nitrogen to about 33% and 77% oxygen would that be a better ratio?
With Oxygen that high, you would not be able to go very deep.
Or what might happen?
Even decompressing the tank itself would help?
I believe the MOD for Nitrox 32 is 110 feet not 130.
It depends if you are using a PO2 of 1.4 or 1.6. 1.4 is what PADI reccomends for recreational divers so i was kinda surprised at 32% --> 130 feet also. (P02 = partial pressure of Oxygen)
@@Saxatillis When I get my tank filled with 32% there's a chart you look at and write down the MOD and it's always 110 ft. MOD. Thanks for you reply.
Yep! The chart is probably all 1.4ATA based numbers. 1.6ATA figures are more common in tec diving. Fun fact, the depth limit of pure O2 (20 feet) is also based 1.6 calculations. Thank you for the awesome discussion!
@@Saxatillis Nice talking to someone that took the time to check it out. I took a PADI O2 course it says oxygen toxicity is 18 feet. Thanks again.
@@Saxatillis Yes 1.4 PO2 is generally considered safenfor any workload, while 1.6 is only considered safe during resting workload. Which is why 1.6 PO2 is considered acceptable on your decompression stops since you're generally calmly ascending, pausing, ascending, etc. This higher PO2 allows you to switch to higher O2 percentages soonest, accelerating your deco.
So, basically, if you're going for an Advanced Scuba certification, Nitrox is going to be your best friend.
Nitrox provides an advantage for extending dive time in a certain range of depths. But it's not good for everything.
How deep do you go when you dive? My son Will-a big 7-year-old fan-wants to know.
Normally not much deeper than 100 feet.
Are helium dissolved in scuba tanks?
Helium is another gas sometimes used to offset nitrogen, for a completely different reason. Helium still becomes absorbed by your tissues and requires decompression, however, it does not cause the narcotic effect of nitrogen at depth (which we did not discuss in this video). This breathing gas (consisting of oxygen, nitrogen and helium) is called trimix, and that's a a video for another time!
Talk about helox?
That's next!
You say that in Nitrox 32, for example, that there's 32% of oxygen and 68% of nitrogen. What are those proportions with the metric system ?
LOL....
@@BlueWorldplus ahahah please more metric system in your awesome videos ! The world would love this ! thank you
so would this explain why i fart more often after diving, nitrogen escaping
What gas do people use to dive to the hmhs Britannic without killing themselves its 400 feet deep
They use trimix, and we are making a video on that.
Talk about trimix
We will get to that!
@@BlueWorldplus 😍😍😘 pls come to Brazil Jonathan!

Not really. By the time you feel something wrong, you have the bends.
