Keep the facts in context.

These figures and reference points summarize public U.S. sources. They do not establish whether a chamber or treatment is appropriate for any individual. Personal health questions belong with a qualified healthcare professional, while equipment decisions should follow the manufacturer’s current instructions and the requirements that apply to the setting.

The page is reviewed as source material changes. Each fact has a stable link so writers and readers can cite the specific reference that supports it.
