If you are actively evaluating hyperbaric chambers for a physician practice, clinic, wellness center, sports medicine facility, or hospital program — this post gives you a clear, honest breakdown of the major players in the market and the key factors that should drive your decision. We will cover the established manufacturers and explain where RxAir360 fits in the landscape.
The hyperbaric chamber market has evolved over decades, and the form factors available today reflect different eras of engineering and different clinical settings. Hospital-oriented systems — developed primarily in the 1960s and 1970s — remain the standard for dedicated hyperbaric programs. But as HBOT expands into outpatient physician offices and specialty clinics, new form factors are emerging to address different space, workflow, and integration requirements. The chamber engineered for a hospital hyperbaric suite is not the right tool for every setting.
This guide examines the primary HBOT chamber form factors on the market, what clinical settings each is engineered for, and the key considerations that should drive a clinical buyer's evaluation. Note: The RxAir360 vertical monoplace chamber is currently pending FDA 510(k) clearance and is not yet available for commercial sale or clinical use. References to the RxAir360 design reflect intended specifications and design objectives.
Hyperbaric chambers fall into several broad categories, each reflecting different design priorities and intended clinical settings. Understanding the form factor landscape — rather than comparing brand to brand — is the most useful starting point for a clinical buyer.
For hospital-based hyperbaric programs treating high volumes of wound care and diving injury patients, traditional horizontal systems have a multi-decade clinical track record. For physician practices, sports medicine clinics, neurological recovery centers, and outpatient operators looking to integrate HBOT into an existing practice setting, the requirements are fundamentally different — and newer form factors are designed accordingly.
Below is an overview of the leading form factors in clinical use today, including representative examples, typical settings, and what each is best suited for.

FDA cleared
Representative examples: Perry Baromedical multiplace systems and similar hospital-oriented designs. Multiplace chambers accommodate multiple patients simultaneously and are typically found in hospitals, military medical facilities, and research institutions. These systems have decades of proven clinical performance.
Footprint: Very large — multiplace chambers require purpose-built hyperbaric rooms; monoplace units from these manufacturers require dedicated suite space
■ Best for: Large hospital programs, military medical facilities, and research institutions with substantial infrastructure and budget.
Founded
1970s
Orientation
Horizontal / Multiplace
Primary setting
Hospital / Standalone clinic
FDA status
FDA cleared
Representative examples: OxyHeal Health Group and similar manufacturers producing both monoplace and multiplace systems for traditional clinical settings. These systems serve hospital and standalone hyperbaric programs with a focus on wound care applications.
Footprint: Large — similar infrastructure requirements to other traditional hospital-oriented systems
■ Best for: Hospital and standalone hyperbaric programs seeking established, traditionally configured systems.
Founded
2000s
Orientation
Horizontal / Soft-sided
Primary setting
Home use / Wellness (non-clinical)
FDA status
Not FDA cleared for clinical use
Representative examples: Summit to Sea and similar soft-sided chambers serving the consumer and mild hyperbaric market for home use and wellness centers. These systems operate at lower pressures and are not FDA-cleared clinical medical devices.
Footprint: Moderate — portable design, but not rated for clinical pressure levels required for FDA-cleared indications
■ Note: Serves a different market segment. Not directly comparable for clinical purchasing decisions.

The right chamber depends on four questions — and being honest about your answers will save you from a costly mismatch between what you buy and what your setting actually needs.
If you are a hospital-based hyperbaric program with a dedicated suite, high patient volume, and an existing clinical team — traditional horizontal monoplace and multiplace systems from established manufacturers are proven, well-supported options engineered for exactly that environment.
If you are a physician practice, sports medicine clinic, neurological recovery center, or outpatient facility looking to integrate HBOT without dedicating significant floor space or undergoing renovation — newer vertical monoplace form factors are being developed specifically for these settings. The RxAir360 vertical monoplace chamber (pending FDA 510(k) clearance) is one such design, engineered with physician-office integration as the primary design objective.
This is the most critical practical question. A traditional monoplace chamber requires a dedicated room of 300 to 500 square feet minimum — plus emergency egress clearance, staff workspace, and in many cases, dedicated oxygen supply infrastructure. If you do not have that space available, a legacy chamber is not viable regardless of your interest in offering HBOT.
The RxAir360 chamber is designed for physician office integration, with a compact footprint intended for integration into many physician office environments. Site-specific modifications may be required depending on the facility.
For high-volume wound care programs treating primarily diabetic foot ulcers and radiation injury — a traditional hospital-based system with an established billing and clinical infrastructure may be appropriate if you have the facility.
For physician practices treating a mix of wound care, neurological recovery, sports medicine, and wellness patients — a compact monoplace that fits your existing workflow is the correct tool. Trying to run a physician-office HBOT program through a hospital referral adds friction, delays treatment, and loses patients.
Legacy chamber manufacturers typically quote equipment cost separately from the substantial facility preparation cost — renovation, dedicated oxygen supply, electrical upgrades, and in some cases structural modifications. For many physician practices, the facility cost alone makes traditional chamber integration non-viable.
The RxAir360 model is designed to reduce facility preparation costs compared to traditional hyperbaric installations. Designed to work within many existing healthcare environments, subject to site-specific requirements. The economics of physician-office HBOT become more accessible when infrastructure requirements are reduced.
This comparison is written honestly. Traditional horizontal monoplace and multiplace systems from established manufacturers have decades of proven performance in hospital hyperbaric programs. If you are evaluating chambers for a hospital-based program with a dedicated hyperbaric suite and high patient volume, those systems are legitimate choices. RxAir360 is developing a chamber designed for a different setting — the physician office, where space, workflow, and infrastructure constraints require a different engineering approach. The RxAir360 vertical monoplace chamber is currently pending FDA 510(k) clearance and is not yet available for commercial sale or clinical use.
