Section 3 - Dive InjuriesFigure 3.5-5 represents the maximum depth of the last dive stratifiedby diagnosis. Deeper then 60 fsw (feet of seawater; 18 msw, ormeters of seawater), there is little difference between the depthsrecorded by injured divers for any of the three diagnostic categories.Figure 3.5-5Maximum depthof last dive bydiagnosis (n=297).Figures 3.5-6 and 3.5-7 show the maximum depth of the dive seriesby gender and the maximum depth of the last dive by gender,respectively. When the injury cases in the sample are analyzed bymaximum depth of the dive series, there is a tendency for DCS IIcases to be associated with deeper depths.Figure 3.5-6Maximum depthof the dive seriesby gender.DAN’s <strong>Report</strong> on Decompression Illness, Diving Fatalities and Project Dive Exploration: 2005 Edition 57
Section 3 - Dive InjuriesFigure 3.5-7Maximum depth ofthe dive series bydiagnosis (n=297).Flying After Diving (FAD)A total of 70 divers (14 percent) in our injury sample reported altitudeexposure after diving. Approximately 20 percent of these exposureswere associated with medical evacuation. DAN does not haveinformation about whether the additional altitude exposure duringthe evacuation worsened their condition or not. There were 19"true" FAD cases in our sample. These 19 divers developed theirfirst symptoms in response to the altitude exposure. Sixteen of the19 flew within 24 hours of diving.3.6 Signs and SymptomsOnset TimeThe onset time for signs and symptoms in our sample of the injureddivers is shown in Figure 3.6-1. The majority of signs and symptomsof decompression illness occurred within one hour of the terminationof the pressure exposure. This was true for all three diagnoseslisted. A large number of the injuries were first manifested prior tothe last dive as in the past. This may be an education problem thatshould be addressed. The onset of signs or symptoms more than 24hours post-dive occurred in very few cases.58DAN’s <strong>Report</strong> on Decompression Illness, Diving Fatalities and Project Dive Exploration: 2005 Edition
