What is the primary consequence of failing to follow proper dive tables?

Failing to follow proper dive tables primarily increases the risk of decompression sickness. Dive tables are designed to provide critical information about safe ascent rates and the maximum amount of time a diver can spend at various depths. These tables take into account the effects of pressure on the body and the way nitrogen is absorbed and released during a dive.

When divers exceed the recommended limits indicated in the tables, they may not allow sufficient time for nitrogen to safely dissipate from their bodies during ascent. This can lead to an accumulation of nitrogen, potentially causing bubbles to form in the bloodstream and tissues. Decompression sickness, often referred to as "the bends," can result in serious health issues, including joint pain, dizziness, paralysis, or even death if not treated promptly.

Understanding and adhering to dive tables is crucial for divers to manage their ascent profiles safely and effectively, thus minimizing the likelihood of experiencing decompression sickness. Other factors, like visibility, equipment performance, and water currents, do not directly relate to the consequences of improper use of dive tables in the same way as the risk of decompression sickness does.
