Oxygen plays a vital role in our daily lives. We breathe because our bodies need oxygen to produce energy. However, in addition to enabling us to function, oxygen’s ability to produce energy plays an important role in wound healing.
Wounds that are infected and inflamed have poor blood flow. Exposure to high concentrations of oxygen (e.g. topical or hyperbaric oxygen therapy) helps accelerate healing by reducing inflammation, promoting collagen formation and stimulating the growth of new cells and blood vessels.
Although many factors affect the wound healing process, a study published in the Journal of Wound Care found that the use of topical oxygen therapy helped nearly half of the previously non-healing wounds close.
