Expert interpretation

Does Exceeding 2 PSI Make a Hyperbaric Chamber a Medical Device?

Direct answer: No—not by pressure alone. Exceeding 2 PSI may matter to engineering, code, safety, or operations, but it is not a universal FDA test for medical-device status. FDA analysis considers intended use, claims, labeling, design, and other facts.

Pressure is an engineering and safety variable. FDA classification, establishment registration and listing, and 510(k) pathways are separate regulatory questions that should not be inferred from a single PSI number.
