As research into decompression sickness deepens, it has been discovered that after a diver stays underwater under high pressure for a certain period, the solubility of inert gases in the body will reach a limit and no longer increase, and the required decompression time and air consumption will not continue to increase.
Saturation diving utilizes this principle, using a high-pressure chamber to supplement underwater air for the diver, allowing the task to be completed underwater in one go, followed by a single decompression to surface, enabling divers to work underwater continuously for hours or even days.
The most critical equipment in saturation diving is the underwater high-pressure chamber, which must provide high-pressure air equivalent to water pressure, offering the diver a high-pressure space for work and rest, preventing decompression sickness due to pressure reduction. Divers can eat, rest, and change gas cylinders inside the high-pressure chamber.
