Section 3 - Dive InjuriesFigure 3.7-2 shows the percentage of each diagnostic category in ourinjury sample that received oxygen on the surface. The percentageof injured divers that had oxygen available to them is unknown.Figure 3.7-2Administrationof first aid oxygenby diagnosis(n=138).Recompression TreatmentThere was a wide range in the times required to obtain recompressiontreatment for the injured divers in our sample (Figure 3.7-3).The majority of the injured divers received recompression treatmentwithin 36 hours; however, some had delays of more than 120 hours.The median time to recompression treatment was 20 hours.Figure 3.7-3Delay torecompressionfrom the timeof first symptomonset (n=297).DAN’s <strong>Report</strong> on Decompression Illness, Diving Fatalities and Project Dive Exploration: 2005 Edition 61
Section 3 - Dive InjuriesFigure 3.7-4 shows the initial treatment table used to compressinjured divers in our sample. The USN Treatment Table 6 was mostcommonly used. Short tables refer to hyperbaric oxygen deliveredat either 90 minutes at 33 fsw (10 msw) or 90 minutes at 45 fsw (14msw). Other tables include Catalina and USN 6A.Figure 3.7-4Initial treatmenttable used torecompress injureddivers (n=297).Figure 3.7-5The outcomesat dischargeby diagnosticcategory (n=293).Figure 3.7-5 describes the resolution of symptoms by diagnosis.Approximately one-third of recreational divers had a residualsymptom at the end of recompression treatment. It is interesting tonote that cases classified as ambiguous had a higher percentage ofresidual symptoms than those in other diagnostic categories. This isunderstandable, since symptoms not caused by decompression illnessmay not respond to recompression treatment. It is possible thatthe ambiguous category contains cases that were not correctly diagnosed.62DAN’s <strong>Report</strong> on Decompression Illness, Diving Fatalities and Project Dive Exploration: 2005 Edition
