What Is ASME PVHO-1? A Plain Guide for Hyperbaric Buyers
Quick answer: PVHO-1 is the ASME safety standard for pressure vessels for human occupancy. It applies when a chamber holds a person at a pressure difference above 2 psi (15 kPa). So it covers hyperbaric, diving, decompression and altitude chambers. For hyperbaric buyers, understanding PVHO-1 helps you evaluate a chamber’s engineering, structural safety, operating pressure, […]
Hyperbaric Chamber Pressure: 1.3 vs 2.0 vs 3.0 ATA Explained
Quick Answer: The hard shell vs. soft shell hyperbaric chamber question comes down to one number first: pressure. Hard shell hyperbaric chambers are rigid steel or acrylic vessels built to ASME PVHO-1 and NFPA 99. They run at 2.0 to 6.0 ATA and are FDA 510(k) cleared for 13 medical uses, including decompression sickness and […]
Hard Shell vs Soft Shell Hyperbaric Chambers: Pressure, Oxygen, Codes and Cost
Quick Answer: The hard shell vs. soft shell hyperbaric chamber question comes down to one number first: pressure. Hard shell hyperbaric chambers are rigid steel or acrylic vessels built to ASME PVHO-1 and NFPA 99. They run at 2.0 to 6.0 ATA and are FDA 510(k) cleared for 13 medical uses, including decompression sickness and […]
Decompression vs Recompression Chambers: What’s the Difference?
Quick answer: Decompression vs recompression chambers are both specialized hyperbaric pressure vessels, but they serve opposite functions in the diving and medical worlds. A decompression chamber lowers pressure slowly after a dive, so nitrogen can leave the body safely. A recompression chamber, by contrast, raises pressure again to treat an injured diver, often for the […]
How Much Does a Hyperbaric Chamber Cost?
Quick answer: Hyperbaric chamber cost starts around $4,000 for an inflatable soft shell and can top $2 million for a hospital multiplace system. In between, personal hard shell units run about $15,000 to $50,000, while clinical monoplace chambers rated 2.0 to 3.0 ATA cost $80,000 to $250,000. If you’d rather pay per visit, clinic sessions […]
