Healing Under Pressure: Hyperbaric Oxygen Therapy in Wound Care
Hyperbaric oxygen therapy (HBOT) delivers 100% oxygen at increased atmospheric pressure, dramatically improving oxygen delivery to tissues. This therapy has proven effective for specific wound types that fail standard treatment.
How HBOT Works
- Patient breathes pure oxygen in pressurized chamber
- Increases oxygen dissolved in blood plasma 10-15 fold
- Oxygen reaches areas with poor blood flow
- Stimulates growth of new blood vessels
- Enhances white blood cell function
- Reduces swelling and inflammation
FDA-Approved Wound Indications
- Diabetic Foot Ulcers: Wagner Grade 3 or higher
- Radiation Tissue Injury: Delayed radiation injuries
- Compromised Grafts/Flaps: Failing reconstructions
- Chronic Refractory Osteomyelitis: Bone infections
- Necrotizing Soft Tissue Infections: Flesh-eating bacteria
- Crush Injuries: Acute traumatic ischemias
- Non-Healing Wounds: Failed 30 days standard care
Treatment Protocol 2024
- Pressure: 2.0-2.5 ATA (atmospheres absolute)
- Duration: 90-120 minutes per session
- Frequency: 5 days per week typically
- Total Sessions: 20-40 treatments average
- Assessment: Wound evaluation every 10 treatments
Latest HBOT Advances
- Portable monoplace chambers for home use
- Combination with growth factors
- Intermittent protocols showing equal efficacy
- Topical oxygen therapy for superficial wounds
- Enhanced protocols with exercise
Patient Selection Criteria
- Transcutaneous oxygen (TcPO2) >40mmHg in chamber
- Failed 30 days of standard wound care
- Adequate nutrition status
- No untreated pneumothorax
- Ability to equalize ear pressure
Side Effects and Contraindications
- Common: Ear pressure, temporary vision changes
- Rare: Oxygen toxicity, lung barotrauma
- Contraindicated: Untreated pneumothorax, certain chemotherapy
- Caution: Claustrophobia, seizure disorders
Cost and Insurance Coverage
- Medicare covers approved indications
- Requires prior authorization typically
- Must meet specific wound criteria
- Documentation of failed conventional therapy
Expert Tip:
- Request TcPO2 testing before starting HBOT—if levels don’t increase to >200mmHg in chamber, you’re unlikely to benefit and can avoid unnecessary treatment.
Next Step
Get evaluated at an accredited hyperbaric center to determine if HBOT suits your wound type and healing potential.
