Part 3/8:
To mitigate the risks of decompression sickness, saturation diving employs a specific methodology: divers remain at high pressure for extended periods. Scientists discovered that the human body can handle a maximum amount of inert gas. Once a diver reaches that saturation point, they can live and work under pressure for days or weeks before decompression.
This technique drastically reduces the ascent time. For example, a diver who spends an hour at 250 feet underwater may face up to five hours of decompression. However, in saturation diving, all necessary decompression occurs in one long session after the work period.
