The beneficial 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 current dive, this stress discount may cause nitrogen to kind bubbles, resulting in DCS. An extended floor interval permits extra nitrogen to be eradicated, decreasing this threat. For instance, a single no-decompression dive usually 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 spread of signs, from gentle joint ache to critical neurological points and even loss of life. By permitting enough time for nitrogen to off-gas earlier than flying, divers considerably scale back their susceptibility to this doubtlessly life-threatening situation. The rules developed by diving organizations are primarily based on intensive analysis and purpose to attenuate the incidence of DCS. Traditionally, the understanding of DCS and its relationship to flying has advanced, resulting in extra conservative suggestions to boost diver security.
