Saturation diving is a unique deep-sea diving method that allows divers to live and work underwater for weeks. In this technique, divers breathe helium or other gases under high pressure, allowing their bodies to become saturated without needing to decompress multiple times. Divers only undergo a single decompression process at the end of their duty, significantly reducing the risk of decompression sickness. This method was created to help commercial divers work on deep underwater projects, such as pipelines, without facing long decompression times.
