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

Duke University’s Center for Hyperbaric Medicine and Environmental Physiology is one of the oldest and most research-active HBOT programs in the United States. The facility holds UHMS accreditation, operates multiplace chambers, and treats the full range of FDA-cleared indications. Duke has contributed to landmark HBOT research including trials on diabetic wound healing and carbon monoxide poisoning.

Their team treats patients across all 14 FDA-cleared HBOT indications while simultaneously contributing to the research that defines treatment standards. This dual role, delivering care while advancing the science, reflects academic medicine functioning at its best.

Why Duke’s Program Sets the Standard

Duke’s hyperbaric medicine center is housed within Duke University Health System, which means patients receive care from physicians who are also researchers and educators. The team includes wound care specialists, diving medicine experts, and physicians board-certified in hyperbaric and undersea medicine.

The program holds accreditation from the Undersea and Hyperbaric Medical Society (UHMS), the medical body responsible for setting 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. This flexibility matters clinically. Some conditions and patient populations respond better to specific chamber configurations. Multiplace chambers allow a medical professional to remain inside with the patient during treatment, which is particularly relevant for patients with acute or emergency indications.

Evidence-Based Conditions Treated at Duke

Duke’s program treats patients across all FDA-cleared HBOT indications. They do not offer HBOT for unproven applications, and they are explicit about the distinction 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

The Clinical Evidence Behind Duke’s Approach

Duke’s protocols are grounded in a substantial body of peer-reviewed literature. For diabetic wound care, a Cochrane review confirmed that HBOT significantly improves wound healing rates (RR=1.94; 95% CI 1.39-2.70) compared to standard care and significantly reduces major amputation rates (RR=0.29).¹ For radiation injury, HBOT is one of the few interventions with Grade B evidence for osteoradionecrosis of the jaw and head and neck radiation damage.

The mechanism for wound healing is well-established. HBOT at 2.0 to 2.5 ATA increases dissolved oxygen in plasma by 10 to 15 times, delivering therapeutic oxygen concentrations to hypoxic wound tissue that standard 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 reverses the fibrosis and vascular damage that radiation causes by stimulating new blood vessel growth in hypoxic, radiation-damaged tissue. A systematic review found that HBOT produced significant improvements in wound healing, reduced pain, and better tissue function across multiple radiation injury sites including head and neck, jaw, and pelvic regions.

The Duke Patient Journey

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.

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 ensures these factors are addressed before any sessions begin.

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

Treatment courses vary significantly by indication. Carbon monoxide poisoning may require 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. Duke’s team tracks outcomes between sessions and adjusts the protocol accordingly.

Research Contributions

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

The academic environment also drives quality in a way that commercial facilities cannot fully replicate. When your physicians are simultaneously responsible for both patient outcomes and published research, the incentive structure favors rigorous measurement and honest reporting. Duke’s track record in both areas is part of why their program is a reference standard in the field.

Medical training is another dimension of the academic contribution. Residents and fellows who train in hyperbaric medicine at Duke carry evidence-based protocols to facilities across the country when they complete their training. This educational multiplier effect is a significant contribution to the broader standard of care in HBOT.

Safety Standards

HBOT involves pressurized oxygen in an enclosed space. 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 process identifies these factors before any sessions begin.

Academic vs Commercial Facilities

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 indications 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 at 1.3 ATA that are not capable of delivering 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 patients with a physician-referred medical need and an FDA-approved indication, an academic medical center like Duke is generally the most appropriate choice. For general wellness curiosity without a specific medical diagnosis, the evidence base does not currently support clinical HBOT for that purpose at any facility.

Making an Informed Decision

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

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

Insurance typically covers HBOT for approved indications at facilities like Duke. The billing team can verify your coverage and obtain pre-authorizations before treatment begins. For more information on hyperbaric chamber costs, see our cost guide.
