What is the purpose of using decompression tables?

Using decompression tables serves a crucial role in dive planning and safety. The primary purpose of these tables is to aid divers in managing their ascent rates after spending time at various depths. When divers ascend too quickly, they risk developing decompression sickness, also known as "the bends," which can be hazardous and even life-threatening.

Decompression tables provide specific guidelines on how long a diver can remain at a certain depth and the necessary rates of ascent to allow nitrogen absorbed by the body to safely off-gas without causing harm. By following these tables, divers can effectively plan their dives, ensuring that they adhere to safe ascent practices and minimize the risk of decompression-related injuries. In this way, decompression tables are vital for the safe and enjoyable experience of diving.
