Mechanism

Gas Volume Reduction

Gas volume reduction follows Boyle's Law: as pressure rises, the volume of any gas bubble falls. In a hyperbaric chamber this physically shrinks bubbles in the blood and tissues — the primary mechanism behind HBOT's role as definitive treatment for decompression sickness and arterial gas embolism.

Detailed mechanism

At 2.8 ATA, gas bubble volume is reduced by approximately 64% compared to atmospheric pressure. This physical compression, combined with nitrogen washout through breathing 100% oxygen, eliminates intravascular and intratissue gas bubbles.
