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 current dive, this stress discount could cause nitrogen to type bubbles, resulting in DCS. An extended floor interval permits extra nitrogen to be eradicated, lowering 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, typically 18 hours or extra.
Adhering to protected floor intervals is essential for diver security. DCS can manifest in a spread of signs, from delicate joint ache to severe neurological points and even dying. By permitting adequate time for nitrogen to off-gas earlier than flying, divers considerably scale back their susceptibility to this probably life-threatening situation. The rules developed by diving organizations are based mostly on intensive analysis and intention to attenuate 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.
