Figure 1: Mechanism of HBOT. Reduction of Nitric oxide (NO) due to inflammation causes vasoconstriction and expression of intercellular adhesion molecules (IAM-1) which aggravates the inflammation by attracting polymorphonuclear cells. HBOT increases NO level in injured tissue causing vasodilatation and suppression of inflammation. It also promotes phagocytosis by immune cells and also stimulates angiogenesis, thus helping in wound healing
