3.0 ATA and Above: Medical-Grade Hyperbaric Safety Standards

Pressure levels of 3.0 ATA and above are an area hyperbaric medicine applies only in tightly regulated clinical environments. Chambers operating at these levels must be manufactured in compliance with pressure-vessel regulations, meet the hyperbaric provisions of international standards such as NFPA 99 for fire safety, and undergo regular periodic inspection. Managing fire risk in an oxygen-enriched atmosphere is the most critical design topic for this class of system.

The other links in the safety chain are human factors: a certified hyperbaric operator, pre-session patient assessment, an emergency evacuation plan, and medical oversight. Professional bodies recommend that treatments in the high-pressure class be delivered only in institutions with this infrastructure, and advise purchasing organizations to request pressure certificates, test reports, and training programs from the manufacturer in writing.
