The advisable minimal floor interval between flying and diving is said to the danger of decompression illness (DCS). Flying after diving exposes the physique to a decrease atmospheric stress, much like ascending throughout a dive. If residual nitrogen stays within the physique from a latest dive, this stress discount may cause nitrogen to type bubbles, resulting in DCS. An extended floor interval permits extra nitrogen to be eradicated, decreasing this danger. For instance, a single no-decompression dive sometimes requires a minimal floor interval of 12 hours earlier than flying, whereas repetitive dives or dives requiring decompression stops necessitate an extended interval, usually 18 hours or extra.
Adhering to secure floor intervals is essential for diver security. DCS can manifest in a variety of signs, from gentle joint ache to critical neurological points and even demise. By permitting adequate time for nitrogen to off-gas earlier than flying, divers considerably cut back their susceptibility to this doubtlessly life-threatening situation. The rules developed by diving organizations are primarily based on intensive analysis and intention to reduce the incidence of DCS. Traditionally, the understanding of DCS and its relationship to flying has advanced, resulting in extra conservative suggestions to reinforce diver security.
