For every 10m (33ft) submerged in water, atmospheres absolute (ATA) increases by 1.
At a depth of 30m (99ft), you would be at 4 ATA.<unk>  Oxygen Therapy (HBOT) utilizes pressure and oxygen to saturate hemoglobin, bot more significantly, blood plasma itself, to provide enough oxygen to meet metabolic demands under various circumstances that may limit hgb oxygen carrying capacity or access.
Vasoconstriction
Maintains oxygenation through increased O2 gradient and plasma saturation, but decreases edema from capillary filtration.
Antibacterial
Directly harmful to anaerobic orgasnisms
May increase neutrophil efficacy
Angiogenesis
Prevention of reperfusion injury
At a depth of 30m (99ft), you would be at 4 ATA.
Maintains oxygenation through increased O2 gradient and plasma saturation, but decreases edema from capillary filtration.
Directly harmful to anaerobic orgasnisms

Pascals Law applies to the diving body (without air filled areas such as lungs) states that the pressure applied to any part of the enclosed liquid will be transmitted equally in all directions through the liquid.
Boyles Law applies to the diving body's air filled areas such as lungs, sinuses, middle ear, and states that the volume and pressure of a gas at a given temperature are inversely related.
At 2 ATA (10m/33ft) a given gas would be 1/2 it's volume, at 3 ATA (20m/66ft) it would be 1/3 it's volume and so on.
At 2 ATA (10m/33ft) a given gas would be 1/2 it's volume, at 3 ATA (20m/66ft) it would be 1/3 it's volume and so on.
