PVHO
PVHO stands for Pressure Vessels for Human Occupancy, a category of standards for chambers designed to hold people under pressure.
PVHO refers to Pressure Vessels for Human Occupancy, a class of equipment and its associated safety standard, ASME PVHO-1. These standards address the unique requirements of vessels that contain people, including viewport design, materials, and testing. Hyperbaric chambers fall under the PVHO category because they house occupants in a pressurized environment.
This entry is part of the OxyEdge Hyperbaric Glossary, a plain-language reference covering the pressure, oxygen-delivery, and chamber-construction terms you will encounter when researching mild hyperbaric oxygen therapy. Understanding this vocabulary makes it easier to compare chamber specifications, evaluate safety features, and ask the right questions before purchasing a chamber for a clinic, wellness center, or home.

- Relief Valve
- A relief valve is a safety device that automatically vents pressure if a vessel exceeds its rated limit.
- Pressurization
- Pressurization is the controlled process of raising the internal pressure of a hyperbaric chamber above ambient levels.
- Depressurization
- Depressurization is the controlled process of lowering chamber pressure back to normal atmospheric levels at the end of a session.
- Air Break
- An air break is a scheduled interval during a session when the user breathes chamber air instead of concentrated oxygen.
