In the case I mention, a large rigid (standard) hyperbaric chamber with room for a health care worker to oversee the process was not in use, but rather a much less expensive semi-inflatable chamber and only room for the child to lie on a table within. Unfortunately the child began moving around as the pressurization commenced, triggering an spark and explosive fire that the mother, unfortunately was watching from outside the chamber. I think the imagination can take hold as to what would become of a child trapped in this "chamber" while it exploded in fire. Beyond horror and of course it was fatal.

Yet, I don't know if any regulation or changes in allowing these non-regulation chambers occurred. There was another incident of a wealthy and someone renowned physician using one in his own home for supposed life-extending benefits. Unfortunately he used it without anyone

What does unregulated and fatal events in hyperbaric chambers have to do with RFK Jr's pushing unregulated unproven stem cell treatments in autistic children while decrying scientifically proven vaccines? Well, both of the two former "treatments" describe the lengths to which his and other advocates will go to ignore actual scientifically proven treatments and avail themselves to the far riskier unproven rantings of nonmedical "influencers" and others online. And there is very little to stop it when the head of our HHS is among those proponents.
