Purchasing a hyperbaric chamber is a significant investment—but purchasing the chamber is only the beginning of its lifecycle. Like any critical piece of medical equipment, a hyperbaric chamber requires a long-term maintenance strategy to remain safe, reliable, and compliant throughout its service life. Unfortunately, many facilities focus on the initial purchase without fully understanding what comes next. As a result, maintenance becomes reactive, budgets become unpredictable, and major lifecycle milestones often catch hospitals by surprise.
The good news is that none of these events should be unexpected. Hyperbaric chambers are designed with a predictable service lifecycle. Annual preventive maintenance, periodic component replacement, Mechanical Overhauls (MOHs), and Cylinder Overhauls (COHs) all play an important role in preserving system reliability, extending equipment life, and supporting compliance with standards such as NFPA-99 and ASME PVHO-2. Understanding that timeline allows hospitals to move from reactive repairs to proactive lifecycle management. Here’s what that journey typically looks like.
Installation: Building the Foundation
A chamber’s lifecycle begins long before the first patient treatment. Proper installation includes verifying that the chamber has been installed according to manufacturer specifications, that utilities are functioning correctly, and that staff receive appropriate operational training.
Facilities should also establish:
• A preventive maintenance schedule
• Maintenance documentation procedures
• Daily operational checklists
• Emergency response protocols
Starting with organized documentation and a clear maintenance plan makes every future inspection and service visit more manageable.
Years 1–10: Preventive Maintenance Is Everything
The first decade of a chamber’s life is largely focused on routine preventive maintenance. Annual PMs are designed to identify wear before it becomes failure and typically include inspections of:
• Pressure systems
• Valves and regulators
• Communication systems
• Safety devices
• Gauges
• Acrylic condition
• Leak testing
Consistent preventive maintenance not only improves reliability but also creates the documentation history needed to support inspections and long-term lifecycle planning.

Around Year 10: Mechanical Overhaul (MOH)
As chambers approach the ten-year mark, normal mechanical wear begins affecting critical system components. A 10-Year Mechanical Overhaul (MOH) is intended to restore mechanical reliability by replacing wear components that naturally degrade over time.
Depending on the chamber model, this often includes servicing or replacing items such as:
• Seals and gaskets
• Valves
• Regulators
• Gauges
• Soft plumbing
• Other critical mechanical components
Unlike a manufacturer “10-Year Tune-Up,” a true Mechanical Overhaul addresses the chamber’s mechanical lifecycle and helps restore long-term performance.

Years 10–20: Monitoring, Planning, and Reliability
Following an MOH, the chamber enters another period of routine maintenance. However, this stage often requires closer monitoring because aging systems naturally experience increased wear.
Facilities should pay particular attention to:
• Recurring maintenance trends
• Aging components
• Acrylic condition
• Repair history
• Documentation quality
This is also the ideal time to begin financial planning for the chamber’s next major lifecycle milestone.

Around Year 20: Cylinder Overhaul (COH)
For many chambers, the twenty-year mark represents the most significant planned maintenance event in the chamber’s lifecycle. A 20-Year Cylinder Overhaul (COH) is a comprehensive service designed to restore the pressure vessel and supporting systems for continued operation.
Depending on the chamber and applicable standards, this may involve:
• Complete disassembly
• Inspection of the pressure vessel
• Component replacement
• Mechanical refurbishment
• System testing
A COH is far more extensive than routine maintenance and should be planned years in advance to minimize operational disruption.

Throughout the Lifecycle: Documentation Matters
One of the most overlooked aspects of chamber ownership isn’t mechanical—it’s administrative. Every preventive maintenance visit, repair, overhaul, inspection, and recommendation should be documented clearly.
Strong documentation helps facilities:
• Demonstrate maintenance history
• Support compliance efforts
• Identify recurring issues
• Improve budgeting
• Prepare for inspections
Without organized records, even a well-maintained chamber can appear poorly managed.

The Longest-Lasting Chambers Have One Thing in Common
The chambers that remain reliable for decades are rarely the newest. They’re the ones supported by consistent maintenance, thoughtful lifecycle planning, and proactive decision-making. Facilities that understand where their chamber sits within its lifecycle are better equipped to:
• Reduce emergency downtime
• Improve patient safety
• Strengthen compliance
• Control long-term costs
• Extend equipment life
Maintenance shouldn’t begin when something breaks. It should begin the day the chamber is installed.
The Bottom Line
A hyperbaric chamber’s lifecycle isn’t defined by a single repair or overhaul. It’s defined by years of consistent maintenance, careful planning, and informed decision-making. Understanding what to expect—from installation through a 20-Year Cylinder Overhaul—allows hospitals to build stronger maintenance programs, avoid unnecessary downtime, and maximize the return on one of their most valuable clinical assets.
When maintenance is treated as a long-term strategy instead of a short-term expense, everyone benefits—patients, staff, and the facility alike.
