I know I keep stressing the relevance of hyperbaric treatments in wound healing.
That's why everytime I come across something that explains why it works
I want to post it here so you can see that it's actually not rocket science to
understand that hyperbaric oxygen is of extreme importance in wound healing.
The following quotation is a bit technical but right to the point:

"In wound healing, biochemical energy supply is a basic requirement. Oxygen is essential for the production of biological energy equivalents (e.g. adenosine triphosphate, ATP) in aerobic glycolysis, the citric acid cycle, and the oxidation of fatty acids. Therefore, sufficient oxygenation of tissue is a prerequisite for adequate energy levels, which are essential for proper cellular function.

In healing tissue, sufficient oxygenation is particularly relevant because of the increased energy demand for reparative processes such as cell proliferation, bacterial defence and collagen synthesis. The strictly oxygen-dependent NADPH-linked oxygenase represents a further highly important enzyme in wound healing; it catalyses the production of reactive oxygen species (ROS) such as peroxide anion (HO₂ ⁻), hydroxyl ion (HO⁻) and superoxide anion (O²⁻). ROS play a prominent role in oxidative bacterial killing and coregulate prevalent processes in wound healing such as cytokine release, cell proliferation and angiogenesis.Against this background, the crucial role of reduced oxygen supply in chronic wound pathogenesis becomes obvious. Chronic wounds are characterized by an insufficient repair process that precludes the establishment of a sustained anatomical and functional result in an appropriate length of time" (1)

Like I said a bit technical but still enough regular English in there to understand

the point.
