High Altitude Flying After Diving

Military divers may be required to perform free-fall parachute operations after diving. Free-fall jumps may be made from higher than 25,000 ft. Decompression sickness (DCS) may occur, particularly after diving, with exposure to high altitude. The U.S. Special Operations Command funded an investigation of high altitude flying after diving at Duke. A single dive was evaluated: 60 feet of seawater for 60 minutes (the no-decompression limit according to the U.S. Navy tables). Three surface intervals were tested: 24, 18 and 12 hours prior to a standardized flight to 25,000 ft for three hours. No difference is risk was evident between the three surface intervals.

In addition to addressing the specific questions of the sponsor, the results of this research can be used to increase the power of evolving decompression models.
