A hyperbaric chamber is a significant capital investment, and for most hospitals, replacing one prematurely is not an expense anyone wants to encounter. Fortunately, chamber age alone does not determine how well a system will perform over time. How the equipment is operated, maintained, monitored, repaired, and planned for throughout its lifecycle can have a major influence on its long-term reliability and serviceability.
There is no single maintenance procedure that makes a chamber last indefinitely. Hyperbaric systems contain mechanical components that wear, seals that deteriorate, acrylic that requires ongoing evaluation, and parts that eventually need replacement. Older equipment may also face changing parts availability and larger lifecycle service requirements.
The goal, therefore, should not be to keep a chamber operating at any cost. It should be to preserve the equipment responsibly, address deterioration before it becomes a larger problem, and make informed decisions about repairs and major service throughout the chamber’s useful life. For hospitals trying to protect that investment, extending chamber life begins long before the equipment is considered “old.”

Preventive Maintenance Is the Foundation
The simplest way to protect a hyperbaric chamber is also one of the most important: maintain it consistently. Preventive maintenance gives technicians an opportunity to evaluate the chamber before an obvious failure occurs. Depending on the chamber and applicable manufacturer requirements, this may involve inspection and testing of pressure-control systems, valves, regulators, gauges, seals, safety devices, communication systems, gurney components, and other mechanical or operational systems.
Regular maintenance also creates something equally valuable—a history. When service is performed consistently, technicians and facility personnel can compare the chamber’s current condition with previous visits and identify developing patterns instead of viewing every issue as an isolated event. The FDA currently recommends that healthcare facilities follow the manufacturer’s recommended maintenance intervals and safety checks for hyperbaric oxygen therapy devices, along with the device’s instructions for use and recommended cleaning procedures. Preventive maintenance cannot eliminate normal aging, but it can help a hospital manage that aging instead of discovering its effects through an unexpected failure.

Pay Attention When the Chamber Starts Behaving Differently
One of the easiest mistakes to make with aging equipment is accepting gradual performance changes as normal simply because the chamber still works. Operators who use the equipment every day are often the first people to notice those changes. A chamber may begin taking longer to pressurize, develop a recurring leak, produce an unfamiliar sound, experience intermittent alarms, or require repeated adjustments that were not previously necessary.
None of those observations automatically means the chamber has a serious mechanical problem. However, a consistent change from normal operation deserves attention. BaroServ discusses this in more detail in Why Is My Hyperbaric Chamber Taking Longer to Pressurize?. The important principle is that facilities should establish what normal performance looks like and investigate meaningful changes rather than simply adapting to them. A small problem identified early may have a straightforward solution. The same problem ignored repeatedly may contribute to additional wear, unreliable operation, or a more disruptive repair later.
⸻
Do Not Let Small Repairs Become Deferred Maintenance
Extending equipment life does not mean avoiding repair costs. In many cases, it means addressing necessary repairs before multiple unresolved issues begin accumulating.
A chamber can remain operational while still developing maintenance needs. A worn seal, recurring leak, aging regulator, damaged gurney component, inconsistent gauge, or other service recommendation may not immediately take the chamber out of operation. That can make postponing the repair tempting, particularly when patient schedules and budgets are tight. The problem is when “we’ll take care of it later” becomes the permanent maintenance strategy.
Hospitals should have a process for reviewing service recommendations and determining:
- What needs immediate correction
- What can be monitored
- What should be budgeted for upcoming service
- Whether a recurring issue may indicate a larger underlying problem
- Who is responsible for making sure the recommendation is resolved
This does not mean replacing components unnecessarily. It means making repair decisions intentionally rather than allowing open recommendations to disappear until the chamber fails.

Protect the Acrylic
For monoplace chambers, acrylic condition deserves particular attention throughout the equipment’s service life. Acrylic is not simply a cosmetic surface; it is part of the pressure boundary and should be cared for, inspected, and evaluated accordingly.
Facilities should follow the chamber manufacturer’s instructions for approved cleaning products and procedures. The FDA’s current HBOT safety recommendations specifically tell facilities to follow manufacturer-recommended cleaning procedures in addition to maintenance and safety checks.
Acrylic condition should also be evaluated over time for changes such as scratches, crazing, chips, chemical damage, clouding, or other conditions that may require technical assessment. The presence of a visible mark does not, by itself, determine whether an acrylic component remains serviceable; evaluation should be based on applicable manufacturer requirements and technical criteria.
The ASME PVHO-2:2025 post-construction standard provides requirements and guidance for the continued operation and maintenance of pressure vessels for human occupancy, including in-service considerations relevant to PVHO acrylic windows. Protecting acrylic from avoidable physical and chemical damage is one of the most practical ways a facility can protect a major chamber component.
⸻
Follow the Manufacturer’s Operating and Cleaning Instructions
Maintenance is only part of chamber longevity. What happens between service visits matters too. Hyperbaric chambers should be operated according to the manufacturer’s instructions and the facility’s approved procedures. Staff should not modify normal operating practices simply to compensate for a chamber that is behaving differently. Likewise, cleaning products, accessories, replacement components, and operational practices should be appropriate for the specific equipment.
The FDA’s HBOT device safety recommendations emphasize following each device manufacturer’s instructions for use, maintaining staff training, using proper grounding, following cleaning and maintenance recommendations, and maintaining appropriate fire-prevention measures. Consistency matters. A well-maintained chamber can still be exposed to unnecessary wear or damage when operating and cleaning procedures are inconsistent.
⸻
Keep the Room and Supporting Systems in the Conversation
Not every performance problem originates inside the chamber. A hyperbaric system depends on the environment and supporting infrastructure around it. Electrical service, gas or air supply, ventilation, exhaust, grounding, and other facility conditions may affect operation depending on the chamber and installation.
That becomes particularly important when a chamber begins experiencing performance changes. Replacing chamber components without considering external conditions can lead to repeated troubleshooting if the actual contributing factor exists elsewhere in the system. The NFPA 99 Health Care Facilities Code includes criteria for the design, maintenance, and operation of hyperbaric chambers and facilities and addresses electrical, fire, pressure, and gas hazards associated with hyperbaric environments.
Hospitals should therefore think about chamber longevity as more than maintaining one piece of equipment. The surrounding facility needs to continue supporting that equipment appropriately as well.
⸻
Keep a Complete Maintenance History
A chamber that has been maintained for fifteen years should have fifteen years of history behind it. Service reports, repair documentation, component replacements, overhaul records, acrylic evaluations, and open recommendations help establish how the equipment has been cared for and what may be approaching next. Without that history, a hospital may know the chamber’s age without truly understanding its condition.
Useful records should make it possible to answer questions such as:
- When was the last preventive maintenance completed?
- Which components have been replaced?
- Are there recurring repair trends?
- Were previous recommendations completed?
- Has the chamber undergone major lifecycle service?
- What is known about the acrylic’s history?
- What significant maintenance is approaching next?
These records become increasingly important as equipment ages. They give technicians better context, help new department leadership understand the chamber, and support more informed repair-versus-replacement decisions. As we explain in What’s Hiding in Your Hyperbaric Chamber Logs?, the value of maintenance records is not simply proving that service occurred. The history can reveal patterns that individual reports may not show on their own.

Treat Major Overhauls as Lifecycle Maintenance — Not Emergency Repairs
Routine preventive maintenance and major lifecycle service serve different purposes. As a chamber ages, replacing individual wear components indefinitely is not always the most effective way to manage the system. Larger planned service can provide an opportunity to address aging mechanical systems more comprehensively rather than waiting for components to fail individually.
For BaroServ customers, lifecycle planning commonly includes a 10-Year Mechanical Overhaul (MOH) and a 20-Year Cylinder/Complete Overhaul (COH), depending on the chamber, its history, manufacturer requirements, and applicable service criteria. These projects should be evaluated and planned well before the target service window rather than treated as unexpected repairs.
BaroServ’s complete hyperbaric chamber maintenance timeline provides a broader look at how preventive maintenance, mechanical service, and major lifecycle work fit together over time. A chamber does not become mechanically new because it continues passing annual maintenance. As equipment ages, the maintenance strategy should mature with it.
⸻
Use the Right Parts and Qualified Technical Support
A repair is only valuable if it actually restores the system appropriately.
As chambers age, facilities may encounter obsolete components, changing part numbers, discontinued assemblies, or difficulty locating replacement parts. That can create pressure to use whatever appears to fit rather than confirming that a component is appropriate for the chamber and application.
Hospitals should work with qualified service personnel who understand the specific equipment and can properly identify replacement components, evaluate compatibility, perform the repair, and document the work. Improvised modifications or inappropriate components can create new problems rather than extending the life of the equipment.
Parts availability should also become part of long-term planning. A mechanically sound chamber may still become increasingly difficult or expensive to support if critical components are no longer reasonably obtainable. Knowing that early gives the facility time to evaluate alternatives instead of making decisions during a breakdown.
⸻
Do Not Confuse “Still Running” With “Still in Good Condition”
One of the most important distinctions in aging medical equipment is the difference between operational and well-maintained. A chamber may still complete treatments while carrying unresolved repairs, overdue lifecycle work, deteriorating components, incomplete documentation, or recurring performance issues. Continued operation alone does not establish the overall condition of the equipment.
Hospitals should look at the complete picture:
Current condition + maintenance history + repair trends + parts availability + lifecycle status + future service needs
That broader view is especially important when leadership is deciding whether to continue investing in an existing chamber, complete a major overhaul, purchase a refurbished system, or begin planning for replacement. The objective should not be to squeeze the maximum possible number of years from every chamber. It should be to obtain the maximum responsible and supportable service life from the equipment.
⸻
Plan Before the Chamber Becomes an Emergency Capital Expense
The best time to decide what happens to an aging chamber is while it is still operating reliably. Hospitals that understand their equipment’s age, maintenance history, upcoming service requirements, and parts outlook have more options. They can budget for an overhaul, evaluate refurbishment, compare replacement equipment, coordinate downtime, or continue maintaining the existing chamber based on actual information.
Waiting until a major failure forces the decision removes many of those options. Long-term planning is therefore part of extending chamber life because it allows necessary service to occur when it makes sense—not only when the equipment leaves the facility no alternative.
⸻
The Bottom Line
There is no shortcut to making a hyperbaric chamber last. Long-term reliability is built through consistent maintenance, proper operation, timely repairs, appropriate acrylic care, strong documentation, qualified technical support, and planned lifecycle service.
Just as importantly, extending equipment life should never mean keeping a chamber in service simply because replacement is expensive. The condition of the equipment, manufacturer requirements, applicable standards, maintenance history, parts availability, and technical findings should guide those decisions.
A chamber that has been cared for throughout its life gives a hospital far more options than one that has spent years accumulating deferred maintenance. The earlier a facility begins managing the chamber as a long-term asset, the better positioned it is to protect both the equipment and the investment behind it.
