What does the term "no-decompression limit" refer to?

The term "no-decompression limit" refers to the maximum amount of time a diver can spend at a specific depth without needing to perform mandatory decompression stops during the ascent. If a diver exceeds this limit, they must take breaks at certain depths to allow for safe off-gassing of nitrogen absorbed during the dive, reducing the risk of decompression sickness or "the bends." This limit is determined based on various factors, including depth, dive time, and the diver's previous dives, and is critical for maintaining safety under water. Understanding and adhering to the no-decompression limits is essential for safe diving practices, especially in recreational diving where divers aim to minimize their risks.
