They are expensive - elite athletes can afford to have them at home. Doctor not included.

it is expensive, time consuming (it is an every day job for six weeks.) and incredibly annoying but

i helped heal my foot
i did not need glasses for months
and generally felt great.

In David Lynch's movie "Blue Velvet," the psycho huffs pure oxygen. When I think of that character, I am reminded of RFK, Jr.

Oxygen would've made too much sense.

It was apparently supposed to by amyl nitrite AKA poppers

Honestly, how can even those who never got past high school biology/chemistry not realize the risk--especially for a child in these devices--much less anyone else? These aren't the hyperbaric chamber 'ROOMs" that are depicted for divers and others, but basically tombs. Hell, I could not even stand a tanning bed--too claustrophobic, but I damned well know how flammable pure oxygen is. Damn!

And, no, I'm not saying hyperbaric oxygen does not have a multitude of valid uses--in fact, more than we are doing now because of cost. Take the cancer patient with unhealed, horrific skin lesions post-radiation. This would be incredibly useful, but rarely used because of availability and cost.

But a child that is awake and with questionable indications? Good gawd.

Big profit in big, ah, cures.

Suppose we could convince RFK Jr. to demonstrate?

Of the Guardian article, RFK Jr insists that HBOT machines are TOO regulated in the US.

I remember hearing that Michael Jackson had one in his house that he used after he got burned doing a tv commercial.

I've only heard of burn victims using it. Kind of ironic in a very sad way.

Apollo 1 was going to be the first test mission for the manned moon flight. NASA was testing it at Cape Kennedy (IIRC). The capsule used a pure oxygen environment. A loose wire sparked, and the oxygen in the capsule fed the flames as the three people in the capsule were burned to death. After that, NASA stopped using pure oxygen environments, and spent a few years revamping the space program.

Wonderful -but destructive - stuff, oxygen.

I don't remember what was the flammable substance that caused there to be an active fire. Oxygen by itself doesn't burn but supplies the oxygenating agent to a flammable substance. I'm guessing the wires that caused the spark were not flammable and I would hope that the insulation itself wasn't. There must have been something proximate to the spark to ignite.

It really emphasizes the differences between legitimate medical use and the proliferation of 'wellness' establishments offering the therapy with no oversight of safety.
