The best way to prevent decompression sickness is to ascend slowly to the sea surface. This allows the body to eliminate excess nitrogen gradually, reducing the risk of forming bubbles in the bloodstream. Ascending rapidly increases the risk of developing decompression sickness. Using nitrogen-free compressed air or compressed gas with high oxygen concentration may not necessarily prevent decompression sickness as they do not address the issue of nitrogen saturation in the body. Adequate humidification of the compressed air is also important for the diver's comfort and safety, but it does not directly prevent decompression sickness.
