Diabetic foot is one of the most common complications of diabetes. It is characterized by insufficient blood supply to the feet, which reduces their pain sensitivity, hinders the healing of wounds and ulcers indicating a progressive necrotic process. The structure of bones and joints weakens. As a result, it leads to deformation of the foot, which prevents walking. The use of oxygen therapy in the combined treatment of diabetic foot has led many patients to complete healing of wounds or to a significant improvement in the local condition, which prevents amputation and allows limiting the scope of amputation.
