One of the most common complaints within healthcare today is hard-to-heal wounds. Besides the patient burden, they also stand for a high cost within medical services. The main problem is that microbes infect the wound and thereby inhibit the wound healing process. Further, the optimism regarding the ability of antibiotics to efficiently handle infections has decreased due to the rising number of multi-resistant bacteria. Oxygen is essential to life and in the wound healing process. It plays a key role in supporting tissue regeneration and repair by inhibiting anaerobic bacteria and supporting the body's natural defense mechanism.
