Overview
Clinical wound-care HBOT follows UHMS guidelines closely. Patients receive daily sessions at 2.4 ATA (occasionally 2.0 ATA for stage-adjusted protocols), with transcutaneous oxygen measurements and wound assessments every 10 sessions. The course length is condition-dependent: diabetic foot ulcers typically require 20–40 sessions, radiation tissue injury 30–40 sessions, and compromised grafts a shorter 10–20 session course.
Wound-care HBOT is the single largest clinical use of hyperbaric oxygen in US hospital-based programmes. Protocols are highly standardised and tied to CMS/Medicare reimbursement requirements. Patients typically present after weeks or months of unsuccessful standard wound care — glycaemic optimisation, offloading, infection management, surgical debridement, advanced dressings — with the HBOT added when progress stalls.
The standard course delivers 2.4 ATA sessions, five days per week, over 4–8 weeks. Interim assessment at session 20 is required for CMS continued-coverage documentation. Transcutaneous oxygen measurement (TcPO₂) establishes baseline wound-bed oxygenation and tracks response. Standard wound care continues alongside HBOT — glycaemic control, offloading, debridement, and advanced dressings.
Response varies by indication. Diabetic foot ulcers typically show measurable improvement in TcPO₂ by session 10, with visible wound improvement by session 15–20. Radiation injury courses are longer (30–40 sessions) and show gradual improvement over the full course. Compromised grafts respond rapidly when initiated within 48 hours of recognised failure.
Protocol Parameters
| Pressure | 2.4 ATA (occasionally 2.0 ATA) |
|---|---|
| Session length | 90–120 minutes with air breaks every 30 min |
| Frequency | 5 days/week |
| Typical course | 20–40 sessions (condition-dependent) |
Indications
- Diabetic foot ulcers
- Delayed radiation injury (soft tissue + osteoradionecrosis)
- Compromised skin grafts/flaps
- Chronic refractory osteomyelitis
Each UHMS-approved wound indication has specific documentation and protocol requirements for CMS reimbursement. Diabetic foot ulcer requires Wagner Grade 3+ classification and failure of 30 days of standard care. Radiation injury requires documented prior radiation and specific tissue classification. Compromised grafts require clinical documentation of threatened tissue.
Evidence Base
UHMS-approved indications with Medicare/CMS reimbursement in the US. Decades of clinical evidence; multiple RCTs and systematic reviews support the standard protocol.
Cautions & Notes
- Requires wound-care team coordination (debridement, offloading, dressings)
- Interim progress assessments every 2 weeks
- Blood glucose monitoring in diabetic patients
- Standard HBOT contraindications apply
Practical Considerations
Wound-care HBOT is typically delivered at UHMS-accredited hospital hyperbaric facilities with CMS billing capability. Patients should expect daily sessions over 4–8 weeks, pre-treatment screening (ear equalisation, chest imaging, cardiovascular review), and ongoing coordination with the wound-care team throughout the course.
Frequently Asked Questions
How many sessions will I need?
Depends on indication and response. Diabetic foot ulcer: typically 20–40 sessions. Radiation injury: 30–40 sessions. Compromised graft: 10–20 sessions. Continued coverage requires documented progress at interim assessments.
Does HBOT replace wound care?
No. HBOT is adjunct to standard wound care — glycaemic control, offloading, debridement, infection management, advanced dressings. All standard interventions continue during the HBOT course.
Is wound-care HBOT covered by insurance?
Yes, for UHMS-approved indications at UHMS-accredited facilities. Medicare covers at approximately $450 per session; most private insurers follow Medicare criteria. Documentation requirements include TcPO₂, wound classification, and progress tracking.
