How should dive tables and computers be used to minimize the risk of decompression sickness?

Using dive tables and computers conservatively is crucial for minimizing the risk of decompression sickness. These tools provide vital information about safe ascent rates, bottom times, and no-decompression limits, which are based on established scientific research regarding how nitrogen absorbs and is released from the body under pressure.

When divers adhere to these guidelines conservatively—meaning they allow for extra time and depth margins—this creates a buffer that can help reduce the amount of nitrogen absorbed. By not pushing the limits of the tables or computers and avoiding any last-minute increased risk factors—like extended bottom times or rapid ascents—divers enhance their safety and significantly decrease the likelihood of developing decompression sickness, also known as "the bends."

Choosing to ignore dive tables and computers entirely can lead to dangerous situations, as divers would lack vital information about safe practices. Similarly, always using these tools at maximum limits neglects the importance of ensuring adequate safety margins, which are particularly important in dynamic diving conditions.
