Summary
This study tested whether adding carbon dioxide (CO₂) therapy to standard wound care helps heal recurrent diabetic foot ulcers. Thirty adults with diabetes and hard-to-heal ulcers received either standard care alone or standard care plus 20 sessions of CO₂ therapy over 4 weeks. The main goal was to see if more ulcers healed completely with the extra CO₂ treatment.
