28. After Diving Both the UHMS and DAN agreethat There can never be a flying after diving rule that is guaranteed to prevent decompression sickness completely Rather there can be a guideline that represents the best estimate for a conservative surface interval for the vast majority of divers There will always be an occa sional diver whose physiological makeup or special diving circumstances will result in the bends To reduce the risk of developing decompression sickness after a single no de compression dive current guidelines suggest waiting 12 hours prior to expo sure to atmospheric pressures equivalent to 1 000 feet 330 meters above sea level or greater When repetitive dives are conducted during the same day or period of days it is suggested that the interval be increased to a minimum of 24 hours Note that land travel to higher elevations after diving must also be considered as an exposure to altitude MORE ABOUT ALTITUDE DIVING WARNING Diving at high altitude requires special knowledge of the variations imposed upon divers their activities and their equipment by the decrease in atmospheric pressures Oceanic recommends completion of a specialized Altitude training course by a recognized training agency prior to diving in high altitude lakes or rivers DataTrans Plus DECOMPRESSION RULES ARE NOT MEANT TO BE BENT 107 OCEANIC 108 Atmospheric pressure decreases as altitude increases above sea le
29. ER DIVING In 1990 the U ndersea and Hyperbaric Medical Society U H MS published a set of guidelines aimed at minimizing the possibility of decompression sickness due to flying too soon after diving The UHMS suggests divers using standard air cylinders and exhibiting no symptoms of decompression sickness wait 24 hours after their last divetofly in aircraft with cabin pressures up to 8 000 feet 2 440 meters excerpted from The UHMS Flying After Diving Workshop The two exceptions to this recommendation are e Ifa diver had less than 2 hours total accumulated dive time in the last 48 hours then a 12 hour surface interval before flying is recommended e Following any dive that required a decompression stop flying should be delayed for at least 24 hours and if possible for 48 hours Since the 1990 UH MS guidelines were introduced data from the Diver s Alert Network DAN was introduced that resulted in DAN s position that A minimum surface interval of only 12 hours would be required in order to be reasonably assured a diver will remain symptom free upon ascent to altitude in a commercial jet airliner altitude up to 8 000 feet 2 440 meters Divers who plan to make daily multiple dives for several days or make dives that require decompression stops should take special precautions and wait for an extended surface interval beyond 12 hours before flight excerpted from DAN s Current Position on Recreational Flying
