Duke Hyperbaric Chamber: Clinical Programs, Indications & What to Know

Duke University’s Center for Hyperbaric Medicine and Environmental Physiology treats all 14 FDA-cleared HBOT indications using UHMS-accredited monoplace and multiplace chambers at pressures of 2.0 to 3.0 ATA. It is one of the oldest and most research-active hyperbaric programs in the United States, and its physicians have contributed to landmark trials on diabetic wound healing and carbon monoxide poisoning. For diabetic foot ulcers, the Cochrane evidence Duke’s protocols rest on shows improved short-term wound healing (RR 2.35 at six weeks).

Duke’s team delivers care while advancing the science, a dual role that reflects academic medicine at its best. This guide covers what the program treats, the evidence behind it, how to get seen there, and how an academic center compares to a commercial HBOT clinic.

What Makes Duke’s Hyperbaric Program Different?

Duke’s hyperbaric medicine center sits inside Duke University Health System, so patients are treated by physicians who are also researchers and educators. The team includes wound care specialists, diving medicine experts, and physicians board-certified in undersea and hyperbaric medicine.

The program holds accreditation from the Undersea and Hyperbaric Medical Society (UHMS), the body that sets treatment standards across the field. UHMS accreditation requires demonstrated adherence to evidence-based protocols, rigorous safety procedures, and qualified medical oversight. Not all hyperbaric facilities meet this standard. Duke does.

The center operates both monoplace (single-patient) and multiplace (multi-patient) chambers. That flexibility matters clinically, because some conditions and patient populations respond better to specific chamber configurations. Multiplace chambers let a medical professional stay inside with the patient during treatment, which is particularly relevant for acute or emergency indications.

What Conditions Does Duke Treat With HBOT?

Duke treats patients across all FDA-cleared HBOT indications. It does not offer HBOT for unproven applications, and the team is explicit about the line between approved and investigational uses. Primary treatment areas include:

• Diabetic foot ulcers and non-healing wounds
• Delayed radiation injury to soft tissue and bone (osteoradionecrosis, soft tissue radionecrosis)
• Carbon monoxide poisoning
• Decompression sickness and arterial gas embolism
• Compromised skin grafts and surgical flaps
• Refractory osteomyelitis
• Necrotizing soft tissue infections

For the full approved list and where these indications come from, see our guide to the FDA-cleared indications for HBOT.

The Clinical Evidence Behind Duke’s Approach

Duke’s protocols are grounded in a substantial body of peer-reviewed literature. For diabetic wound care, the 2015 Cochrane review (Kranke et al.) pooled five trials and found HBOT increased the rate of ulcer healing at six weeks (RR 2.35; 95% CI 1.19 to 4.62; P=0.01) compared with standard care.¹ The review was careful about limits: that healing benefit was not evident at one-year follow-up, and the pooled effect on major amputation did not reach statistical significance (RR 0.36; 95% CI 0.11 to 1.18). The honest read is that HBOT improves short-term healing for diabetic foot ulcers, while its effect on preventing amputation remains uncertain in the trial data.

The healing mechanism is well established. HBOT at 2.0 to 2.5 ATA raises dissolved oxygen in plasma by 10 to 15 times, delivering therapeutic oxygen to hypoxic wound tissue that normal blood flow cannot adequately perfuse. This drives angiogenesis (new vessel formation), fibroblast proliferation, collagen synthesis, and antimicrobial activity against anaerobic bacteria.²

For radiation injury, HBOT is one of the few interventions with meaningful evidence, working by stimulating new blood vessel growth in hypoxic, radiation-damaged tissue. Reported outcomes include improved healing, reduced pain, and better tissue function across head and neck, jaw, and pelvic radiation sites.

How Do You Get Treated at Duke?

Treatment at Duke begins with a physician evaluation and medical clearance. HBOT is not available without a proper referral and assessment. The clinical team reviews your complete medical history, current medications, and any conditions that might affect eligibility or require protocol modification. Most patients arrive through a physician referral, though you can also contact the center directly.

Common considerations during evaluation include lung conditions (which affect pressure tolerance), cardiac history, ear and sinus anatomy, and current medications. Certain chemotherapy drugs are contraindicated with HBOT. The medical team addresses these factors before any sessions begin.

During sessions, patients breathe 100% oxygen at pressures between 2.0 and 3.0 ATA depending on the indication, for 60 to 90 minutes. Ear pressure equalization is required during pressurization and feels similar to descending in an aircraft. Duke’s staff trains patients in equalization techniques before the first session, and in the multiplace chamber a trained attendant can accompany them inside.

Treatment courses vary widely by indication. Carbon monoxide poisoning may need only 1 to 3 emergency sessions. Diabetic foot ulcers typically require 20 to 40 scheduled sessions. Radiation injury protocols often run 30 to 60 sessions. The team tracks outcomes between sessions and adjusts accordingly.

Research Contributions

Duke’s hyperbaric program has contributed to the scientific literature for decades. Its physicians have published on wound healing mechanisms, optimal treatment pressures, carbon monoxide toxicology, and the physiological effects of elevated pressure on human tissue. That published work informs protocols at facilities across the country.

The academic environment drives quality in a way commercial facilities cannot fully replicate. When physicians are responsible for both patient outcomes and published research, the incentives favor rigorous measurement and honest reporting. Duke’s record in both areas is part of why the program is a reference standard.

Medical training is another dimension. Residents and fellows who train in hyperbaric medicine at Duke carry evidence-based protocols to facilities across the country when they finish, an educational multiplier effect that raises the broader standard of care.

Safety Standards

HBOT involves pressurized oxygen inside an enclosed hyperbaric chamber, so safety is non-negotiable. Duke’s chambers meet ASME PVHO-1 standards for pressure vessels used for human occupancy and comply with NFPA 99 requirements for hyperbaric facilities in health care settings.

Equipment undergoes regular inspection and testing. Staff are trained in emergency procedures specific to hyperbaric environments, including fire safety (oxygen-enriched atmospheres require particular precautions), emergency depressurization, and management of uncommon adverse events including oxygen toxicity seizures. A 2024 review confirmed that HBOT has a well-established safety profile when administered by trained personnel following established protocols.³

Patient screening is thorough. Patients with untreated pneumothorax, certain cardiac conditions, severe claustrophobia, or specific medication combinations require additional evaluation or protocol modification before treatment. Duke’s physician-led screening identifies these factors before any sessions begin.

Is an Academic Center Better Than a Commercial HBOT Clinic?

Not all hyperbaric facilities operate at the same standard. Academic medical centers like Duke differ from standalone commercial clinics in several meaningful ways:

• Physician oversight: Academic programs require board-certified hyperbaric medicine physicians. Some commercial facilities are supervised by physicians with limited HBOT-specific training.
• Scope of practice: Duke treats only FDA-approved indications with evidence-based protocols. Some commercial facilities offer HBOT for unapproved uses including autism, Lyme disease, and general wellness, which the FDA has specifically warned against.
• Equipment: Academic centers use clinical-grade hard chambers at therapeutic pressures. Some commercial wellness facilities use soft-shell chambers near 1.3 ATA that cannot deliver clinical-grade HBOT.
• Insurance integration: Academic programs have established billing relationships with insurers for approved indications. Commercial wellness facilities typically operate cash-pay only for off-label applications.

For a physician-referred medical need with an FDA-approved indication, an academic center like Duke is generally the most appropriate choice. For general wellness curiosity without a specific diagnosis, the evidence base does not currently support clinical HBOT for that purpose at any facility. For context on how academic programs compare to celebrity-driven media narratives, see our post on the Michael Jackson hyperbaric chamber story.

Making an Informed Decision

If you or a family member are considering HBOT for a medical condition, the path starts with your treating physician. HBOT is most appropriate when a physician who knows your full medical history determines that your condition is one of the FDA-cleared indications and that the benefits outweigh the risks for your situation.

Duke’s program typically accepts patients via physician referral, and its evaluation process is thorough, which serves both your safety and the quality of your treatment plan. The commitment is significant: daily sessions five days a week for weeks to months, depending on the indication.

Insurance typically covers HBOT for approved indications at facilities like Duke. The billing team can verify coverage and obtain pre-authorizations before treatment begins.
