What does "retroactive decompression" refer to?

• A. Increasing dive times without a break
• B. Adjusting dive times based on nitrogen absorption after a dive
• C. Rising to the surface without stops after a deep dive
• D. Planning future dives based on past performances

Answer: (B)

The term "retroactive decompression" specifically involves adjusting dive times based on nitrogen absorption after a dive. This concept is crucial for understanding how nitrogen behaves in the body during and after diving. When divers complete a series of dives, their nitrogen levels can accumulate, and the body continues to absorb nitrogen during the ascent and surface intervals. Therefore, evaluating and potentially adjusting future dive profiles based on the nitrogen absorption from previous dives is essential for avoiding decompression sickness. This approach takes into consideration how the body has absorbed nitrogen and how it may affect subsequent dives, ensuring that divers remain within safe limits to minimize the risk of decompression illness. This understanding is vital in dive planning and helps divers to manage their exposure to nitrogen effectively, enhancing safety during diving operations.
