Nitrox for Liveaboard - Great Barrier Reef

[tarponchik]

The paper's focus on problems with high oxygen pressures is dealing with very long exposures to very high PPO2s, something that has been well understood for many decades. They reference prolonged exposures to PPO2s of 1.0 or above. Technical divers are taught to take air breaks when doing long decompression stops using pure oxygen. People doing decompression therapy in a chamber also take periodic air breaks.

Though this is indeed discussed in the paper, this is only part of the paper.

The thread went off the rails with post #23 then #27. Too bad; nice thread topic.

And why did you fail to mention #44, Mr Rosencranz? Too bad when I nailed it with a quote from peer-reviewed paper?

Because mainly two things: lots of speculative words (may, could, etc) in the quote and the paper, and they tend to reference their own work a lot in the citations in your quote....not a compelling approach.
Most good science is based on consensus and facts, not speculation and self-referential reviews.
Is this a case where you cherry-pick some words out of some quotes, and then explain them with your own ideas? (post #40)
Also, post #49 rather nicely picks apart your quote and its context.

#49? Nope, it does not. The claim that "The paper's focus on problems with high oxygen pressures is dealing with very long exposures to very high PPO2s..." is false. The paper is a general review of the matter and though very long exposures are reviewed, they are not the paper's focus. Diving with very long exposures is not even mentioned in the Abstract.

@tarponchik why do you scuba dive given that you are convinced breathing compressed air is so harmful? Don't you care about your health and well being? Given that you're so knowledgeable and aware of the dangers of high PPO2 it appears you are recklessly endangering your life for no good reason.

Maybe he is diving with hypoxic air and shallow in order to keep his ppo2 low. Thwn he needs to add additonal deco (10 O2 with 90 N2, for a 10-15m dive )

Thought it was a "she" as per the feminine sounding user name. Looked at the profile details and laughed when I read about the Nitrox certification. Odd that someone who believes we are slowly being killed by oxygen would get a certification to breathe MORE of it.

I also drive a car frequently, despite the fact that 40,990 people died in road accidents in 2023, according to NHTSA. I also prefer to hike alone and dive solo though this is probably dangerous some times. You keep making silly remarks because you miss the whole point: if diving Nitrox gives you more bottom time and you consider it worthy, dive Nitrox. If diving Nitrox does not give you more bottom time, do not dive Nitrox. It's very simple. If you want a piece of cake, go for it, but too much sugar is bad for you, so do not eat cake 3 times a day. Same here.
