How does Hyperbaric Oxygen Therapy (HBOT) enhance the growth of new blood vessels (Angiogenesis)?

Injury or damage to tissues also results in damage and destruction of the supporting blood vessel structures. The healing process is reliant on these structures for supply of the blood containing the cells and nutrients that carry out and enable healing as well as the removal of damaged cells, debris and foreign micro-organisms.

Research has demonstrated that treatment with hyperbaric oxygen therapy significantly increases the number and actual size of blood vessels in damaged tissues and wounds. This allows the healing process to occur faster speeding the recovery of the injury or wound.
