Hyperbaric oxygen therapy heals diabetic wounds and prevents amputations
Hyperbaric oxygen therapy heals diabetic wounds and prevents amputations
Why diabetic wounds fail to heal and how oxygen therapy changes the outcome
Diabetes impairs wound healing by damaging blood vessels and reducing oxygen delivery to tissue. Diabetic foot ulcers affect approximately 15% of diabetic patients and are the leading cause of non-traumatic lower limb amputations. When circulation is compromised, wounds become hypoxic and the body cannot produce the collagen, immune cells and new blood vessels needed for healing.
Standard wound care combined with antibiotics often fails to close diabetic wounds because the underlying oxygen deficiency remains unaddressed. HBOT changes this by dramatically increasing oxygen concentration in wounded tissue, even in areas with severely damaged circulation. Medicare, the FDA and the AMA all support HBOT as a proven treatment for diabetic wounds, and numerous private insurance companies cover the condition.
A note about insurance coverage: While many insurance companies cover HBOT for this condition, we cannot guarantee that your specific plan will cover treatment. Coverage depends on your specific policy and plan terms, the diagnosis code from your referring physician, your insurer’s medical necessity criteria, prior authorization approval, in-network status, and other plan-specific factors. Our Patient Care Coordinators will advocate on your behalf — please speak with them at or before your consultation so we can verify your benefits and request prior authorization on your behalf.

Clinical evidence for HBOT in diabetic wound healing
HBOT for diabetic wounds is one of the most extensively studied applications in hyperbaric medicine, supported by randomized controlled trials, Cochrane systematic review and Medicare approval.
Londahl et al. — randomized controlled trial (2010): The landmark RCT published in Diabetes Care enrolled 94 patients with chronic diabetic foot ulcers and randomized them to HBOT or sham treatment. The HBOT group achieved a significantly higher rate of complete wound healing at 1 year (52% vs. 29%), a statistically significant difference (p=0.03). Patients with transcutaneous oxygen tension (TcPO2) above 100 mmHg during HBOT were particularly likely to respond. This is the definitive trial establishing HBOT’s efficacy for diabetic foot ulcers. [Londahl M et al. Diabetes Care. 2010;33(5):998–1003. PMID: 20427683]
Kranke et al. — Cochrane systematic review (2012): The Cochrane review of HBOT for chronic wounds analyzed 12 randomized trials and found that HBOT significantly reduced the risk of major amputation and increased the likelihood of complete wound healing compared to standard care at 1 year. The review concluded that HBOT reduces the risk of diabetic foot amputation by approximately 50%, consistent with real-world clinical experience. [Kranke P et al. Cochrane Database Syst Rev. 2012;4:CD004123. PMID: 22513920]
Hypoxia reversal mechanism: Diabetic foot ulcers fail to heal primarily because microvascular and macrovascular damage reduces tissue oxygen tension to levels below those required for fibroblast proliferation, collagen synthesis, neutrophil killing and angiogenesis. Transcutaneous oximetry studies by Hopf et al. established that wound oxygen tension below 40 mmHg predicts non-healing, and that HBOT can raise peri-wound TcPO2 above the 200 mmHg threshold required for reliable healing response. [Hopf HW et al. Arch Surg. 1997;132(9):997–1004. PMID: 9301620]
Angiogenesis and stem cell mobilization: Thom et al. demonstrated that HBOT at therapeutic pressures mobilizes CD34+ progenitor cells from bone marrow in a nitric oxide-dependent mechanism, increasing circulating progenitor cells eightfold. These cells home to ischemic wound tissue and incorporate into new capillary structures, providing lasting improvements in wound bed vascularity that persist after HBOT ends. [Thom SR et al. Am J Physiol Heart Circ Physiol. 2006;290(4):H1378–1386. PMID: 16284238]
Infection control: HBOT’s bactericidal activity against anaerobic organisms, potentiation of aminoglycoside antibiotics through restored tissue oxygen, and reconstitution of neutrophil oxidative killing in hypoxic wound tissue address the chronic infection cycle that prevents diabetic wounds from progressing through normal healing stages. [Park MK et al. Antimicrob Agents Chemother. 1991;35(4):762–766. PMID: 1850960]
Your path from diabetic wound to complete healing
We design a personalized HBOT wound care protocol coordinated with your physician and diabetes management team.
Comprehensive wound and diabetes assessment
Our medical team evaluates your wound, diabetes management, circulation and previous treatments to design an individualized HBOT protocol with your referring physician.
Daily HBOT sessions in our pressurized chambers
You breathe 100% oxygen in a pressurized chamber for approximately 90 minutes per session. Diabetic wound protocols typically involve 30 to 60 sessions.
Visible wound closure and tissue regeneration
We monitor wound healing progress at every visit. Most patients see visible improvement as new tissue grows, infections clear and wound edges begin to close.
Frequently Asked Questions
Answers to the questions patients and families ask most about hyperbaric oxygen therapy for diabetic wounds and foot ulcers.
Diabetes damages blood vessels, starving wounds of oxygen needed for healing. HBOT delivers 1,200% more oxygen by dissolving it directly into blood plasma, bypassing damaged vessels. This oxygen stimulates new blood vessel growth, mobilizes stem cells, fights infection and activates collagen production — everything the body needs to close wounds that have resisted other treatments.
