Hello,

We have a facility that has a Hyperbaric Suite with (3) Chambers. Each chamber has O2, HP O2 (70-90psi), Med Air, and Med Vac. These gases are piped through a Zone Valve, and monitored with an AAP.

They also have HP Med Air (70-90 psi) that’s fed from a simplex Air Manifold located in a closet in the chamber room. This is piped over to wall outlets & strictly used to run the chamber vents – not patient respiration. They got written up on their annual survey that the room is not ventilated, relief is not piped outside, no source valve, etc. per NFPA. I don’t see anything in NFPA99 or FGI guidelines on this. My thought is if it’s not patient respiration, they wouldn’t need to meet all of those standards. Curious to hear what others might think?
