nitrox downsides

TROLL!! He's going on the "ignore" list

I report before ignoring. This forum has at least one actual troll who keeps getting kicked off but reappears with a new name to strike again.

I used to dismiss claims that Nitrox would be less fatigueing to the diver. Then I got old. And then I developed some sort of afib that may eventually require a probe going in and desensitizing some nerves and which cannot be treated in the normal means of suppressing my heart rate with na drug due to a life long fitness regimen that leaves me with a 40 BPM or less pulse. So, now after exhaustive (pun) testing I have come to believe that Nitrox may well reduce fatigue and at least when I am wanting to hyperventilate due to inadequate blood circulation during an afib event triggered by chasing a turtle/shark/UFO etc, well, I just feel all warm and fuzzy all over about it. People go to O2 bars to breath cherry flavored O2 and then go vape with Nicotine and other carcinogens and undo what good might have been done, I guess it makes sense that a mix higher than ambient O2 might be less fatiguing, maybe. Unless Nitrox is all that is available I am probably not going to waste it tooling around in 15 feet of water shooting macro subjects. If it is cherry flavored though I am a go. Dinosaurs and giant dragon flies breathed Nitrox. Do not tell the climate folks that the oxygen content of the atmosphere has also changed, they could ban Nitrox as a pollutant. It was after all once called Voodoo Gas . I have not been able to get any Cretaceous opinions on the matter.

Zero. Relevance?

That explains why it's all theoretical to you.

In all of your rather detailed posts with provided references there was nothing about measurable objective positive effects in recreational divers breathing trimix vs nitrox in depths of 100-130'.

cool. Go do some trimix dives in the rec range and keep your END above 100ft and report back.

I accept this and have posted as much. That much said, I've never ever heard of pulmonary toxicity symptoms due to breathing recreational nitrox blends nor can I find a single other reference to it here on this forum nor anywhere else online.

Furthermore, I've suggested 2 effective ways of further diagnosing and dealing with it which were immediately rebuked by a trimix/nitrox instructor who is perfectly ok with this woman continuing to dive nitrox despite the serious symptoms

You'd think. I suggested as much in an earlier post. Slowly increase the percentages of 02 until the trigger point is reached (without her actually knowing the blend to rule out subjective effects), and I was accused of treating the poor lady like a monkey.
The certified Trimix/nitrox/CCR instructor in question would rather just keep feeding her nitrox and having her deal with the symptoms.
Go figure.

You keep writing crap.
I'm not a scientist.
I'm not a doctor.

We detected this problem and sent her to see a specialist.

This diver received permission to dive from this doctor following medical examinations carried out with recommendations from this specialist.

She doesn't necessarily dive with us and we're not going to keep her on a leash.
She is free to do what she wants, where she wants, following her doctor's advice.

You, who know nothing about the medical file and not much about diving, dare to judge a doctor's opinion?

Keep spouting nonsense, you're a diving god, you understand everything and know better than everyone else about diving, and keep giving your ****** advice.

hi I just got my nitrox cert and can't find any reason not to dive nitrox vs air. aside from the MOD and slight extra cost is there any reason not to dive nitrox?

How old are you? And how long do you plan on diving? You should ask a pulmonologist what are the long term affects of high oxygen mixes on human lungs.

I was going to like your post until you went all in on Climate Conspiracy. Just sad.

32% is not a high oxygen mix. Air at 75feet is about the same PPO2 as Nitrox at 50feet. So it's about time and depth and the PPO2. This is why we have MOD limits. Whatever the mix, in recreational scuba you are very unlikely to get anywhere close to the toxicity limits of oxygen for this to matter.
