High-level subject matter with a simplified explanation accessible to everyone. Not all teachers posses this skill.

If Jonathan, Todd, woody and Gus open up a scuba shop and teach diving together, it might be the best experience you can have

I never understood why people used END, equivalent narcotic depth instead of partial pressure or crazy factor for nitrogen. Well done by standardizing our measurements with crazy factor.

I'm guessing here but I think its because narcosis is different to everyone so if you turn it into a "what it would be like on air at a certain depth" that allows people to get a feel for what the narcosis would be like on trimix where they intend to go. I like "Crazy factor" because it's a simpler concept to explain and remember and calculate.

Thank you Jonathan! You definitely have a wonderful way to express some of the more complex diving things!

Hello, I am a total fan of your video. I watch it as soon as they come out. Thank you a lot. I am a diver using the metric system and that is why the pressure calculations are simpler than with imperial units: for me 130 feet gives 40m, which is a PN2 of 4 ata (9:26).

True, the metric system is way easier to calculate!!! But for whatever dumb reason, the USA never full embraced the metric system.

I just saw the poster for Nitrox certification course in nearby divingshop, and you then posted this video introducing trimix…😂😂😂 This makes me feel Like to having a try on different gases. Okay, already wrote down ‘nitrox certification’ in my memo book…

If you want to stay longervon moderate depth or take a diving vacation with multiple dives per day, it‘s worth it.

Excellent, excellent video, Jonathan. Very well thought out explanation of a complex subject. You would make an excellent instructor. I look forward to your Great Lakes wreck diving videos.

Love it! Thank you for explaining all this, Jonathan!

Another great video of yours Jonathan. So well explained. Many instructors are far away from proper simple and clear explanation, that makes you wonder even more about the subject. Thank you very much.

cool stuff ! never realized what u breathe on diffrent depths , they do sound like dangerous mixes if u have to cater to an unknown dive / exploration

Great stuff Johnathan, thank you.

Another amazing episode! I really appreciate these kinds of videos. I haven’t reached that level in my training yet but I find this topic extremely interesting and I love learning more. Dr. Simon Mitchell has some incredible talks on these topics as well. I highly recommend his talk about their experiments using hydrogen on deep dives

Jonathan I'm not a diver. This video was very interesting and because of your ability to teach difficult subjects on a level we can all understand, I've been able to learn all about diving, gasses, & safety. You're always entertaining, thanks so much. Happy New Year to you, your family and crew. ❤

This was really informative. Thanks

Great video for a rec diver looking down my monical into the deep end of the sea.

Incredibly well-explained for a complex topic! As a diver training through multiple agencies (tech), I thought it would be responsible to correct one important fact: the primary reason for nitrox (increasing oxygen to replace nitrogen) should not be narcosis related. It should be used to increase non-deco limits(NDL) in repetitive dives/multiple cylinders or speed up deco (and potentially to decrease body exhaustion - though the research here has been harder to prove). These should be the main reasons because O2 is actually treated as an equally narcotic gas as nitrogen in some tech agencies (and thus would be considered in part of the END calculation!). There are debates on whether it is less narcotic as nitrogen because it is metabolized, but it should be emphasized that there has been some research showing compressed oxygen does contribute to the narcosis effect! (hence "nitrogen narcosis" may not be an accurate term for the effects under water)

@BlueWorldplus

Күн бұрын

I know some agencies use O2 as a narcotic gas but I disagree with that. If it is narcotic, it's MUCH less narcotic than nitrogen and could be considered not significant at anything other than extreme depths.

Very good video very well explained..

Very interesting stuff! Although i think i'll stick to normal air and depths, perhaps Nitrox some day, good enough for entertainment 🙂

out of personal experience? how do you feel with each formula experimented? what do you prefer? transitionally speaking I think it will take time for people to adjust with different formula ratios. long term experience with new adjust must be considered as patient progressive.

Just dove Capote Zenope in January, Was 2 meters below my dive master! My SAC rate is cr@p that at 115 feet I got Narced out of ming. Scared the cr@p out of DM and ran out of air.

I am just curious does this only apply with pressure on your body directly, what I mean is in a submarine to they have to breathe a different air mixtures and pause for decompression or does it only apply if the pressure is on your body directly.

What about HeliOx? Ive heard about it, but what would be its use case?

@BlueWorldplus

Күн бұрын

Heliox (Hydrogen/Oxygen with no Nitrogen) was experimented with back in the day. They figured that by getting rid of ALL the nitrogen, you would get zero chance of narcosis. However, what they found was that you get HPNS. So now all the deep diving gases have at least a small amount of nitrogen which helps calm the HPNS a bit.

@@BlueWorldplus Ah. Didnt know it was an old school thing. Good to know. Thanks.

Nowadays, it is apparently possible to replace nitrogen with hydrogen :-) I was supposed to visit in the fall, the trip was postponed by a year, in the Deep Hole in Dubai and dive there with Triox, not Trimix. I have diving experience only with Nitrox. Some people love the terms - ha ha ha... I don't think I'll ever breathe hydrogen but it's the next step in current deep diving.

@Yggdrasil42

There's a recent presentation by Simon Mitchell on KZread. Cool stuff. They mainly experiment with hydrogen because it's the lightest gas to breath. Gasses, when breathed under high pressure, become dense and this makes it hard for your body to breathe. Even trimix with its helium. Hydrogen is even less dense so easier to breath. The main downside is that it's explosive when mixed with oxygen so it should be handled with much care on the surface. Apparently it's safe to breathe if it's mixed with a maximum of 4% oxygen, so very hypoxic and only suitable for very deep dives.

I used the END calculator to find the END of 130 feet for each blend, not the actual mathematical PN2. I thought about explaining that, but that's a long story...the math is not really that important. (I figured someone was going to ask about this!) It's just the concept that reducing the nitrogen reduces the "Crazy Factor". If you take the class, they will go into the math a lot more.

@johnmarriott6998

What Jonathan didn't make clear is that both Nitrogen and Oxygen contribute to narcosis. You need to add together ppO2 and ppN2 and then the numbers will work

Diving for results: shoot fish, repair coral or do construction or repair. Reason is I'd rather be productive. Thoughts?

13:01 Should have said Nitrogen, not Helium...
