<p>The gold standard for diabetic foot ulcer treatment includes debridement of devitalised wound tissue, management of any infection, revascularisation procedures when indicated and offloading of the ulcer. Hyperbaric oxygen therapy (HBOT) has been promoted as an effective adjunctive treatment for diabetic foot wounds. The effects of HBOT on improving wound tissue hypoxia make it a useful adjunct in clinical practice for diabetic foot ulcers. It may reduce the risk of lower-extremity amputation and improve healing in people with diabetes with foot ulcers.</p>
