CASERO presented for chronic wounds, also known as summer sores, on his left carpus. Despite wound management and attempted bandaging for several months, the wounds were not improving.

Significant wound edge epithelialization and contraction was noted at every bandage change during his hyperbaric treatment period. He received a total of 24 treatments in the hyperbaric chamber. In addition, Casero received careful bandaging and a skin grafting procedure on the palmar wound. After three months of treatment, his wounds were almost completely healed and he was ready to go back into work.
