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 is not large, but it is growing — and the options available to clinical buyers are more varied than most purchasing teams realize. Legacy manufacturers dominate the hospital and standalone hyperbaric center market. But as HBOT moves into outpatient physician offices and specialty clinics, the limitations of legacy designs are becoming apparent. The chamber that was engineered for a hospital hyperbaric suite is not the right tool for a 12-room family medicine practice.
This guide profiles the five primary players in the clinical hyperbaric market, explains what each is built for, and lays out a side-by-side comparison across the factors that matter most to clinical buyers.
The clinical hyperbaric chamber market is dominated by a small number of established manufacturers — most of whom have been building chambers for hospital environments since the 1960s and 1970s. That legacy is both their strength and their limitation.
For hospital-based hyperbaric programs treating high volumes of wound care and diving injury patients, these legacy systems have a proven track record. But for physician practices, sports medicine clinics, neurological recovery centers, and wellness operators looking to integrate HBOT into an existing setting, the requirements are fundamentally different — and the legacy designs were not built for them.
Here is an honest overview of each major player, what they are known for, and what clinical setting they are best suited for.
Founded
1973
Orientation
Horizontal
Primary setting
Hospital / Standalone clinic
FDA status
FDA cleared
Primary market focus: Hospital-based hyperbaric programs, wound care centers, and military medical facilities. Sechrist is the most widely deployed monoplace chamber manufacturer in the United States, with thousands of units in active clinical use.
Footprint: Large — requires dedicated hyperbaric suite, typically 300–500 sq ft minimum with full door clearance
■ Best for: Established hospital hyperbaric programs with dedicated facility space and high patient volume.
Founded
1960s
Orientation
Horizontal / Multiplace
Primary setting
Hospital / Military / Research
FDA status
FDA cleared
Primary market focus: Hospital hyperbaric programs, multiplace chambers for military and research applications, and high-volume wound care centers. Perry Baromedical is one of the oldest names in the industry with a strong reputation for engineering quality.
Footprint: Very large — multiplace chambers require purpose-built hyperbaric rooms; monoplace units 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
Primary market focus: Hospital and standalone hyperbaric programs, wound care applications. OxyHeal manufactures both monoplace and multiplace systems with a focus on traditional clinical settings.
Footprint: Large — similar infrastructure requirements to Sechrist and Perry Baromedical
■ 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
Primary market focus: Primarily the consumer and mild hyperbaric market — soft-sided chambers for home use and wellness centers. Summit to Sea is not a clinical medical device manufacturer in the same category as Sechrist or Perry Baromedical.
Footprint: Moderate — portable design, but not rated for clinical pressure levels required for FDA-cleared indications
■ Note: Summit to Sea serves a different market segment. Not directly comparable for clinical purchasing decisions.
Founded
2023
Orientation
Vertical — seated upright
Primary setting
Physician office / Outpatient clinic
FDA status
FDA 510(k) pending — submission in progress
Primary market focus: Physician offices, outpatient medical practices, sports medicine clinics, neurological recovery centers, and wellness centers seeking clinical-grade HBOT without hospital infrastructure. The first monoplace chamber designed specifically for standard physician exam rooms.
Footprint: Compact — fits standard 10×12 ft exam room, no renovation required
■ Best for: Physician practices, sports medicine clinics, and outpatient facilities integrating HBOT without dedicated hyperbaric infrastructure.

| Clinical pressure | Yes (3 ATA) | Yes (3+ ATA) | Yes (3 ATA) | Low (1.3–1.5 ATA) | Yes (3 ATA) |
| FDA status | Cleared | Cleared | Cleared | Not cleared (clinical) | 510(k) pending |
| Medicare billable | Yes | Yes | Yes | No | Yes (post-clearance) |

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 — Sechrist and Perry Baromedical are proven, well-supported options. Their systems are built 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 — none of the legacy systems were designed for you. The RxAir360 vertical monoplace is.
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 fits in a standard 10 by 12 foot exam room — the same footprint already in your practice. No renovation, no dedicated suite, no structural modification.
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 eliminates facility preparation cost entirely. Standard power, existing space, no renovation. The economics of physician-office HBOT only work when the infrastructure cost is removed from the equation.
This comparison is written honestly. Sechrist and Perry Baromedical are well-respected manufacturers with 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, their systems are legitimate choices. RxAir360 is not trying to compete in that setting — we are opening a new market that those systems cannot serve. The physician office is our lane.
