- Benefits and risks of scuba diving with Enriched Air Nitrox (EAN). In this episode, Lyell delves into the world of Nitrox diving. What exactly is Nitrox? What are the benefits to divers of diving with Nitrox? What are the risks of diving with Nitrox? Is it really safe gas to use while diving, or is it dangerous. All of these questions and more will be answered!

Great Video! Every diver should consider getting Nitrox certified. It's a great tool to have in your scuba diving toolbox.
Great summary, although I personally would have avoided describing going into a required deco situation as an 'emergency'. I am aware of instances where divers have panicked when they realised they were at or beyond NDL and acted inappropriately, ie bolted for the surface, exactly because they thought it was an emergency. I believe this is something that needs to be highlighted properly. Better to say that you shouldn't exceed your NDL but be aware of what you need to do if it happens and what info your computer will be showing you. As you will know, the RDP does hint at this by including extra stop time as you get toward the boundaries of the table.
Very informative thank you .
Great video. Clear and thorough explanation.👏
First, I love your videos and content. Big Thanks! Your approach is excellent, very interesting and WELL done. Keep them coming. One small item I wanted to point out is at 5:55 in the video, on the chart you stated depth in meters, not feet. This isn’t a big deal, just wanted you to know you meant to say feet as in 50 feet, not 50 meters. :-).
Great video. I love diving with nitrox.
Glad you enjoyed
I wouldn’t dive without NITROX unless I had to due to depth. I feel better coming out of the water than I do going in!
Good video
Thanks Dan. Glad you enjoyed it!
2:33 Nitrox mixtures should not be written as, for example, "EANx 32" or "EANx 36," because the "x" stands for a missing variable. If the percentage of oxygen is known, then it's not a missing variable. Thus "EANx" is correct for Nitrox in general, and "EAN32" or "EAN36" (or "EAN40" or whatever) is correct if the O2% is known. I'm guessing that PADI does it the way they do because they think "Nx" stands for "Nitrox," but that's an odd usage.
Yup my error. Nothing to do wirh PADI. No need to bash the agency. Bash me instead.
@@everythingscuba I'm not "bashing" PADI, I'm just making an observation. Look at the bottom left of a PADI Nitrox RDP card and you'll see that they write "EANx 32 Only" or "EANx 36 Only" with big white letters in a black box on it.
@@seikibrian8641 PADI is American and Americans butcher the English language . For example Americans drive on a parkway and park on driveway .
@@sarahann530 The English do their fair share of butchering as well. For example, they'll say they searched for evidence "with a fine toothcomb." All combs have teeth. The proper expression is "with a fine-toothed comb," describing the high degree of care used in the search.
I love your videos please get rid of your lighting 😱
Wow you guys really blown up and well it is if go too deep 😂
Ha. We see what you did there! Thanks guys!
At 4:15 or so, that's not really factual. Regardless of your depth on air, your cylinder mixture is still 21%/~78%. The difference is the uptake. You're increasing the rate at which you're consuming that air. At 10m you're cylinder is still 21% oxygen but you're taking in twice as much. Same for nitrogen.
I assume you are referring to the section regarding Henry’s Law. While I don’t disagree with your premise that your gas cylinder percentages of oxygen and nitrogen, do not change, and you’re also correct that with increasing depths and increasing pressure, you thus uptake faster…Henry’s Law refers to the fact with increasing pressure there is increasing solubility of gas i.e. more gas will dissolve into tissues for example nitrogen uptake into tissues with increasing pressure. Thanks for watching!
