This study focuses on individuals living with chronic wounds, which are sores that do not heal within the expected timeframe. The research aims to evaluate the impact of hyperbaric oxygen therapy, a method where a person breathes oxygen through a specialized breathing tube while inside a pressurized chamber, on the types of bacteria living in these wounds. These bacteria are part of the wound microbiome, which refers to the collection of tiny living organisms that inhabit the area around and inside the wound.

Participants will undergo a period of treatment lasting six weeks. During this time, the effects of the pressurized oxygen on the wound’s environment and the healing process will be observed. The study will look at how the different types of microorganisms in the wound change and how this influences the body’s ability to repair the tissue and reduce the size of the sore.
