What is a no decompression dive and how does it differ from other types of diving?

A no decompression dive is a type of Scuba diving where the diver can ascend to the surface without needing to make decompression stops. This means that the diver has not stayed underwater long enough or gone deep enough to accumulate enough nitrogen in their body tissues to require decompression stops during ascent. In contrast, other types of diving, such as decompression diving, involve longer or deeper dives that require the diver to make stops during ascent to allow excess nitrogen to safely leave the body.
