Topical oxygen therapy used to improve healing in large retrospective study of wounds of mixed aetiology

This 200-patient study demonstrated topically administered oxygen can increase healing in chronic wounds of all aetiologies. Topical oxygen was most effective in venous ulcers (VLUs), and achieved an average closure of 52% over the study period. Longer treatment times were associated with more effective wound healing, evidenced by average wound closures of 67.9%. Portable topical oxygen delivery devices provide effective therapeutic options for home-based wound care.
