Decompression divers must understand how inert gas is what?

Decompression divers must understand how inert gas is absorbed and eliminated because this knowledge is crucial for managing the risks associated with diving. When divers descend, the pressure increases, leading to the absorption of inert gases, such as nitrogen, into the tissues of the body. Understanding this absorption process helps divers plan their ascent and decompression stops to minimize the risk of decompression sickness (DCS), commonly known as "the bends."

Moreover, when a diver ascends, the decrease in pressure allows the inert gas to be eliminated from the body. It is essential to recognize the proper rates of ascent and the appropriate decompression stops to allow for safe elimination of these gases without forming bubbles in the tissues and bloodstream, which can cause serious injuries.

Thus, the concept of both absorption during descent and elimination during ascent is fundamental to the safe practice of decompression diving, making it essential for divers to be well-versed in these processes.
