Gas Volume Reduction

According to Boyle's Law, increased pressure reduces the volume of gas bubbles in the blood — the primary mechanism 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.
