I regret not getting clearer pictures to zoom in and see the words on the instruments but I felt the need to be discreet as I was just walking by, these ocean-front home garages are rarely/NEVER left open unattended. What is this mystery chamber?

One more different angle picture in the comments, you can see the seating bench in the chamber.

In case anyone else was curious, looks like the most common use is for the rich to recover faster from the bruising and swelling of plastic surgery.

My wife has to have a full knee replacement. I wonder if this treatment would help her recovery.

I'm not a billionaire but I'd gladly pay the cost for a bunch of sessions if it would help.

Just go grab this one. The garage door is open!

[–] LemmyKnowsBest@lemmy.world 9 points 3 days ago (4 children)

For reals. Because update: I walked past it again after work this evening now dark outside, and the garage door is still wide open! Fully lit inside and still no one in there. Very weird. Maybe they forgot they left their garage door open. But this area, there are billionaires and there are homeless people, you know how beaches are, so people are usually really tight about their security so it makes me wonder why they left their garage door open all day and I also wonder how there's been no intrusion or robbery yet.

Hyperbaric treatment is used for wound care. My wife had to do a bunch of it after a surgery, but only because things weren't healing well on their own.

Given the choice, she would have preferred to skip it. It's very annoying because you can't wear any moisturizer, chap stick... anything with oil. O2 reacts with oils and it's a fire hazard.

[–] TranscendentalEmpire@lemmy.today 20 points 3 days ago (12 children)

Well, the good news is that this is just a fake hyperbaric chamber that rich people get swindled into buying because they don't actually understand science.

Actual hyperbaric chambers are illegal to own and operate in residential properties, so there are private companies that build chambers that do not run on the right amount of pressure or oxygen to reap the benefit of hyperbaric medicine.

This is just an expensive form of snake oil.

I don’t think it’s right to say these treatments don’t do anything positive.

I recommend them for everyone with over 100 mil dollars. Make sure to get the nicer carpeted version and wear comfy socks!

My wife had to have her knee replaced a year ago, and she's only in her 30s. The recovery was slow, and she complains about the range of motion she lost, but it's a lot more stable than her old knee at least.

But her case was also one-of-a-kind complicated, because she has a rare genetic condition where her kneecaps basically never worked in the first place. In any case, she got through it.

Anyway, I hope everything goes well for your wife.

That's definitely a hyperbaric chamber.

I did an image search for "hyperbaric chamber" and this place popped up in the first few results, and whatever chamber they're using looks very similar to that one, so it's likely from the same manufacturer https://www.facialplasticsurgeryofaustin.com/about/our-on-site-hyperbaric-oxygen-treatment/

Edit: specifically that's apparently a hyperbaric oxygen therapy or HBOT chamber

[–] Today@lemmy.world 6 points 3 days ago (4 children)

Could it be for diving decompression?

[–] jaennaet@sopuli.xyz 7 points 3 days ago

I guess you could use it for that too? And it's not like it's 100% guaranteed that it's only an HBOT chamber, since I'd assume you could use it with just air instead of more-or-less pure oxygen

[–] KeenFlame@feddit.nu 3 points 3 days ago

That is what they use them for. So yes.

Fuck me, I'm dumbfounded that people with billions would choose to live on a fucking main street.
There are more cars in that one picture than I see in a week. Christ.

[–] LemmyKnowsBest@lemmy.world 8 points 3 days ago* (last edited 3 days ago)

It's a few houses down from one certain house where JFK & Marilyn Monroe played hide the salami together, where also years later Paul McCartney & John Lennon were last together in the same place (or something Beatles last time something). Paris Hilton also had a house here further up the road before the January 7th fires consumed it. These homes are usually empty because the people who own these houses have several homes all over the world, so these are just an occasional beach retreat for them, an eyesore and ocean-view-blocker for everyone else.

Anyway my point is, it's a popular well-known area, right by the ocean, which means everybody wants a piece of it, both major highway & billionaire beachfront homes. In fewer words:

Pacific Coast Highway.

[–] walden@wetshav.ing 9 points 3 days ago

Would a billionaire live on a busy street like that? Maybe just a multimillionaire.

Earlier I saw a stand-up comedian lambast a pregnancy test company for marketing their products as "the most sophisticated technology you will ever urinate on" as a tagline that plays poorly with women but strongly with men. Men would love to piss on something high tech.

Personally, if I was a billionaire, I’d rather have a maid and groundskeeper than a hyperbaric chamber.

[–] crank0271@lemmy.world 75 points 3 days ago

If you were a billionaire you wouldn't have to choose. It's no longer "or," it's "and" for everything.

I think it's a Macy-Pan Hyperbaric Oxygen Chamber. I found an image but the link doesn't load

That site sometimes loads and sometimes doesn't, but this appears to be the exact model

Beachfront billionaire with a SCUBA hobby perhaps? That's a hyperbaric chamber.

What I thought too, but it's not like you can climb out the water with the bends and stroll home.

That looks like a BMW R Nine T. That's a cool motorcycle!

And whatever it is, their motor vehicle registration expired in 2024. I did the courtesy of blurring out the license plate number though.

This is precisely the kind of smartassery I am here for.

[–] Cort@lemmy.world 3 points 2 days ago* (last edited 2 days ago)

I was assuming it was a fancy cold plunge pool since there are 2 massive water chillers hooked up to it. But the 2nd photo makes it clear it's hyperbaric O2. The water chillers must be for climate control since you don't want any fans or anything else that may cause a spark in a high oxygen environment

I could see an ultra rich scuba diver buying a hyperbaric chamber for their yacht. Decompression sickness is deadly and this is the only treatment. Hyperbaric chambers aren't common, there might not be one in an entire country. We get warnings about their availability when traveling. If you're diving off your yacht in a remote location, this could save your life.

That said, there's a step set up. Maybe they're shore diving at home and decided to splurge on something crazy and unnecessary.

Time machine. That's how billionaires get richer, they go back in time and change little things to benefit themselves.

Just close their garage door and unplug the control panel.

All that money and their garage looks as dirty and pleb as the rest of us.
