Efficacy of combined hyperbaric oxygen therapy and topical haemoglobin spray in treating hard-to-heal sloughy wounds

In this study, a greater number of wounds in the oxygen group healed. Combining HBOT with topical haemoglobin spray provides oxygenation to the wound for longer, primarily because patients can receive 90 minutes of HBOT daily. This ensures that patients benefit from both systemic and local oxygen. This combination therapy may effectively address the problem of hypoxia and promote healing in hard-to-heal wounds.
