In a Nitrox dive plan, what does "no-decompression limit" refer to?

In a Nitrox dive plan, the term "no-decompression limit" specifically refers to the maximum time a diver can spend at a certain depth without needing to perform decompression stops during ascent. This is crucial for preventing decompression sickness, which can occur when nitrogen bubbles form in the body due to rapid changes in pressure. The no-decompression limits are determined based on the dive's depth and the gas mixture used, providing divers with safe parameters for their underwater excursions.

When divers remain within these limits, they can ascend directly to the surface without pauses, assuming they follow the other guidelines for safe diving. This knowledge is essential for planning dives effectively and ensuring safety during ascents in Nitrox diving practices.
