Nitrogen.
Nitrogen should be used with oxygen under pressure to prevent the development of decompression sickness. When breathing high-pressure oxygen for a period of time, the body accumulates excess nitrogen which can form bubbles in the blood when pressure is reduced. This can result in decompression sickness, also known as "the bends."
The gas commonly mixed with oxygen for diving is nitrogen. This mixture is called Nitrox or Enriched Air Nitrox, and it helps reduce the risk of decompression sickness when diving at certain depths.
Breathing pure oxygen when diving deeper than 40 feet can help prevent nitrogen narcosis, reduce the risk of decompression sickness, and allow for longer bottom times.
Hyperbaric treatment involves breathing pure oxygen in a pressurized chamber. This increased pressure can help increase the amount of oxygen in the bloodstream, which can promote healing in conditions like decompression sickness, non-healing wounds, and carbon monoxide poisoning.
Oxygen is the component of air that we consume, so it must be continuously replaced as the astronauts breathe it. The the other components of air, mostly nitrogen, simply come from the initial air supply and do not need to be replaced.
how does decompression sickness effect the body
Scuba divers who surface too quickly after a deep dive are prone to decompression sickness.
The deepest depth that can be dived to (on air) and saturate and then surface without getting decompression sickness in general is about 20 feet (6 meters). This is known as the Minimum Bends Depth. Any depth greater than this depth can result in decompression sickness depending on the time underwater.

The Bends
Decompression Sickness-rapid reduction of the atmospheric pressure
It is any illness that is related to a release of pressure from the body such as barotrauma .. baro (pressure) trauma (injury). It includes decompression sickness, but it is not limited to decompression sickness. It is also not limited to diving even though that is what is mostly thought of when discussing decompression illness or DCI.
No
It is called "The Bends"
The bends are also known as decompression sickness.
It is sometimes called the bends
Because the pressure inside a submarine is the same as at the surface. In otherwords, they never experience any pressure increase on their body since the submarine is protecting them.
