Bio-oxidative therapies like Hyperbaric Oxygen Therapy (HBOT) and Topical Oxygen Therapy (TOT) enhance wound healing by improving tissue oxygenation, supporting immune response, and promoting tissue regeneration.

Key Points:

• Oxygen’s Role in Healing:

  • Essential for all phases—inflammation, proliferation, and remodeling.

  • Supports collagen synthesis, angiogenesis, and microbial killing.

• Hyperbaric Oxygen Therapy (HBOT):

  • Involves 100% oxygen at high pressure (2.0–2.5 ATA).

  • Increases oxygen delivery, reduces edema, enhances infection control.

  • Indicated for diabetic ulcers, chronic wounds, radiation injuries, crush injuries, and refractory osteomyelitis.

  • Backed by evidence and guidelines (UHMS, CMS).

• Topical Oxygen Therapy (TOT):

  • Delivers oxygen locally at normal pressure.

  • Promotes epithelialization and reduces infection in superficial wounds.

  • Portable, non-invasive, cost-effective alternative for selected patients.

• Clinical Integration:

  • Should complement standard wound care (debridement, off-loading, infection control).

  • Therapy choice depends on wound type, depth, patient factors, and access to facilities.

• Limitations:

  • HBOT requires infrastructure, has contraindications (e.g., pneumothorax, certain drugs), and risks oxygen toxicity.

Conclusion:
Bio-oxidative therapies are valuable tools in modern wound management. HBOT benefits deep, chronic wounds, while TOT is suited for superficial lesions. Personalized, evidence-based use enhances healing outcomes.
