Hyperbaric oxygen therapy salvages compromised grafts and flaps
Hyperbaric oxygen therapy salvages compromised grafts and flaps
Why grafts and flaps fail and how oxygen therapy saves them
Skin grafts and surgical flaps can fail when the transplanted tissue does not receive adequate blood supply and oxygen to survive. Compromised grafts and flaps may show signs of discoloration, swelling, decreased temperature or tissue breakdown. Underlying conditions such as diabetes, radiation injury, infection and poor circulation increase the risk of failure.
Time is critical — the typical protocol for compromised grafts or flaps begins with two treatments per day to salvage as much tissue as early as possible. HBOT delivers 1,200% more oxygen to the threatened tissue, stimulates new blood vessel growth into the graft bed, enhances immune function and supports the collagen production needed for successful integration. Over 25 years, Bay Area Hyperbarics has achieved over 90% salvage success for referred graft and flap patients.

Clinical evidence for HBOT in graft and flap salvage
Hyperbaric oxygen therapy for compromised grafts and flaps is supported by extensive clinical evidence and approved by the FDA and Medicare.
Salvage mechanism: Grafts and flaps fail primarily due to insufficient vascularization and oxygen delivery at the recipient site. HBOT addresses this by increasing tissue oxygen levels by 1,200%, enabling compromised tissue to survive while stimulating angiogenesis to establish permanent blood supply. This dual mechanism — immediate oxygen support plus long-term vascular growth — is why HBOT is so effective at salvaging threatened tissue.
Angiogenesis and growth factors: HBOT stimulates the release of vascular endothelial growth factor (VEGF) and other angiogenic factors that promote new blood vessel formation in the graft bed. Studies in the Journal of Plastic, Reconstructive & Aesthetic Surgery and Undersea and Hyperbaric Medicine confirm that HBOT significantly increases neovascularization and collagen deposition in compromised grafts.
Anti-inflammatory and immune effects: HBOT reduces the inflammatory response that can damage fragile graft tissue, enhances white blood cell function to prevent infection, and improves antibiotic penetration to the surgical site. This is particularly important for grafts placed in irradiated, infected or diabetic tissue beds.
Clinical outcomes: Bay Area Hyperbarics has treated hundreds of referred graft and flap patients over 25 years, achieving a higher than 90% salvage success rate. Studies support that HBOT significantly increases flap and graft survival even in patients with underlying complications including radiation injuries, tissue infection and diabetes.
Timing is critical: Research consistently emphasizes that early initiation of HBOT — ideally beginning with twice-daily treatments — maximizes tissue salvage. The sooner oxygen delivery is restored to compromised tissue, the more viable cells can be preserved.
Hyperbaric treatment of delayed radiation injury
Dr Robert Marx documented the benefit of hyperbaric oxygen for treatment of osteoradionecrosis (ORN), which is the result of an aseptic, avascular necrosis of the bone. Marx showed that for hyperbaric oxygen to be consistently successful, it must be combined with surgery and antibiotics. Marx highlighted the need for pre-surgical hyperbaric oxygen to improve tolerance to surgery: Patients should receive 20 pre-surgery treatments, followed by ten post-surgical treatments.
Diffuse injury patterns that were a result of isodosing arose. The tumor was treated as a spheroidal mass in this study, recognizing that the larger number of target cells would be at the center. As such, researchers gave a boost dose to the center of the tumor. Because the mass decreases as you move away from the center, researchers delivered a lower dose. However, the patient developed an additional diffuse area of injury from beam divergence. Radiation wounds demonstrate a progressive, proliferative endarteritis. This is an obliterative process that destroys the tissue blood supply. The tissue ends up chronically hypoxic, fibrotic, and with a dearth of blood vessels. There is no satisfactory treatment of radiation necrosis using conventional therapy. It is difficult if not impossible to provide adequate nutrients and oxygen to the devascularized tissues. Surgical reconstruction of previously irradiated tissue has a very high failure rate due to poor healing. Hyperbaric oxygen therapy helps build new blood vessels in bone that typically has low blood flow in the first place. As such, it delivers oxygen, the key nutrient required for the bone to heal, and to help deliver the antibiotics required.
Hyperbaric oxygen therapy for the management of chronic wounds: patient selection and perspectives.
The use of HBOT for chronic, problem wounds is best defined for DFUs, but there is a sound fundamental basis for its use for some other chronic wound types.
The Undersea and Hyperbaric Medical Society includes “select problem wounds” as an accepted indication for the use of hyperbaric oxygen (HBO2), however, the treatment of diabetic foot ulcers (DFUs) has dominated any discussions of problem wounds because of the prevalence of DFUs in today’s patient population and the reimbursement available for their treatment. Other wound types (eg, calciphylaxis ulcers, sickle cell ulcers, and pyoderma gangrenosum) that have well-deserved reputations as problem wounds have been infrequently treated with HBO2. While there are sound fundamental reasons why additional oxygen may have benefits in the treatment of these wounds, the challenge is finding enough high quality evidence to support routine use of HBO2.HBOT Improves Recovery from Acute Traumatic Injuries

Urgent treatment protocol for compromised grafts and flaps
Time is critical. Contact us immediately if your graft or flap shows signs of compromise.
Urgent assessment and coordinated surgical care
Our medical team evaluates the graft or flap status and coordinates with your surgeon to begin HBOT as quickly as possible to maximize tissue salvage.
Twice-daily HBOT sessions to salvage tissue
The typical protocol begins with two treatments per day during the acute phase, then transitions to daily sessions. Each session involves breathing 100% oxygen for approximately 90 minutes.
Progressive tissue integration and surgical success
We monitor graft viability throughout treatment. Most patients see progressive improvement in tissue color, temperature and integration as new blood vessels establish.
Frequently Asked Questions
Answers to the questions patients ask most about hyperbaric oxygen therapy for compromised grafts and flaps.
HBOT delivers 1,200% more oxygen to the compromised tissue, sustaining cell viability while stimulating new blood vessel growth into the graft bed. This dual mechanism preserves tissue that would otherwise die and establishes the permanent blood supply needed for successful integration.
