The Wealthy Are Paying Big Money to Pump Oxygen into Their Mountain Homes

Perhaps I'm misunderstanding, or approaching this wrong as someone who doesn't tend to have bad reactions to altitude if I am careful with it. But doesn't this kind of defeat the purpose? Won't your acclimation take a lot longer (or never happen fully?) if you're spending most of your time at sea-level pressure? I imagine these folks would be very comfortable in their houses, but the sudden increase back to 10k feet of pressure whenever they left home would leave them out of breath and susceptible to acute mountain sickness even weeks after they arrived in Colorado. Unless I am misunderstanding how acclimation works, this seems like refusing to rip off the Band-Aid.

There's also the other rich-person-pressure trend of sleeping in hypobaric chambers to simulate altitude and promote red blood cell and lung growth. Seems like probably at least one of these practices is wrong!

I can't find any reference to fire besides fire place, to flammability or to oxygen partial pressures in this system.

What keeps this from being a fire hazard? If I were trying to oxygenate a house without setting it on fire I'd be putting a diffuser into a central air system not piping a point source of concentrated oxygen straight into rooms.

It cost $18M. Bro. $18M. Just… no.
