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 pressure, oxygen delivery, and chamber construction. Understanding this vocabulary makes it easier to compare specifications, evaluate safety features, and ask informed questions before purchasing equipment for a commercial wellness business or home wellness space.
