Summary Hyperbaric oxygen therapy (HBO) could be described as a short‐term, high‐dose oxygen inhalation and diffusion therapy, delivered systemically through airways and blood, achieved by having the patient breathing concentrated oxygen at a pressure higher than 1 absolute atmosphere. In clinical practice, monoplace or multiplace hyperbaric chambers are used to achieve this. Treatment is usually given as daily 90‐ to 120‐min‐long HBO sessions at pressures between 2.0 and 2.5 absolute atmosphere, aiming for 30–40 treatment sessions. The use of HBO as treatment of diabetic foot ulcers has been founded on weak scientific ground, although the outcomes from previous studies are in concert with the conclusions from preclinical studies and supports the theoretical framework of HBO reversing hypoxia‐induced pathology. Two well‐designed randomized double‐blind trials have put HBO on firmer ground and may justify adjunctive HBO treatment to a selected group of patients with nonhealing diabetic foot ulcers. Some health economic studies suggest potential cost effectiveness, but these studies are limited by deficient primary clinical data and should be interpreted with caution. Several issues remain to be addressed, such as developing robust criteria to improve treatment protocols, determining which patients are likely to benefit, and when to start and stop treatment.
