What does the Decompression Theory primarily focus on?

Decompression Theory is fundamentally focused on the physiological aspects of diving, particularly how to manage the ascent from underwater safely to prevent the formation of nitrogen bubbles in the body. As divers descend, they absorb nitrogen from the breathing gas under increased pressure. If a diver ascends too rapidly, the drop in pressure can lead to the formation of bubbles in the tissues and bloodstream, resulting in decompression sickness, commonly known as "the bends."

To mitigate this risk, the theory emphasizes the importance of a slow ascent. This allows for the gradual release of nitrogen from the body, which is essential for maintaining diver safety and avoiding serious medical issues. Moreover, divers often utilize safety stops, which are pauses at certain depths during ascent, to further enhance nitrogen elimination. Thus, the focus on a slow, controlled ascent is a crucial aspect of safe diving practices under Decompression Theory.
