FAQs

How is 2.2 ATA different from a 2.0 ATA chamber?

Most hard-shell multiplace chambers operate at 2.0 ATA; the M5502 reaches a true 2.2 ATA for protocols that call for a higher pressure ceiling. Higher pressure should always be used under appropriate guidance — consult a qualified physician.

What does “ASME code compliant” mean for this chamber?

It means the 4 mm 304 stainless-steel pressure vessel is engineered and documented to American Society of Mechanical Engineers (ASME) pressure-vessel standards — a recognized benchmark for the hull, welds, and pressure system.

Do I need special venting?

No. The dual redundant compressor system maintains a safe 23% ambient oxygen level in the room while delivering up to 95% oxygen by mask, so no special venting is required. Follow local codes and the manufacturer's installation guidance.

Is hyperbaric therapy right for me?

Hyperbaric oxygen therapy is generally used to support recovery, circulation, and overall wellness, but individual results vary and it is not a substitute for medical care. Consult a qualified physician before beginning any hyperbaric protocol.
