Section 2 - Project Dive Exploration (PDE)Figure 2.3-3 shows the chronic health conditions reported by thedivers providing PDE data in 2003. Some divers reported morethan one condition. As in previous years, seasonal allergies werethe most frequently reported conditions in our sample (18 percent),followed by history of ear and sinus problems (13 percent).High blood pressure was reported in 7 percent of divers. Four percentof divers (83) reported asthma as a chronic health problem.Sixty-four percent divers with reported asthma used medications.Specifically, 48 divers used inhalers, five used oral drugs and fiveused both. A total of 1.2 percent of the sampled divers reportedhaving diabetes (Type I or II). Less than 1 percent of participantsreported having experienced DCI previously.Figure 2.3-3Percentageof PDE volunteerslisting thefollowing chronichealth conditions.PDE divers were also questioned about acute medical problemsthey experienced before diving. Figure 2.3-4 shows some of theacute conditions recorded. Ten percent of divers were prone to seasickness,and most of them were taking medication against it.Bone- or joint-related conditions or injury, represented on Figure2.3-4 as "orthopedic conditions," were reported by nearly 8 percentof divers. Minor complaints such as an upper respiratory infection(URI) were reported by 5 percent of divers.DAN’s <strong>Report</strong> on Decompression Illness, Diving Fatalities and Project Dive Exploration: 2005 Edition 29
Section 2 - Project Dive Exploration (PDE)Figure 2.3-4Percentageof PDE diversreporting thefollowing acutehealth problemsbefore a dive.2.4 DivesMost PDE data (98 percent) were collected during recreational divingin an ocean (saltwater) environment; 1.3 percent of PDE diveprofiles came from freshwater diving. Only 72 dives were recordedin caves or caverns, and 12 dives were done in Antarctica.Figure 2.4-1Percentageof the PDEsample by diveplatform(n=26,767).Figure 2.4-1 shows the dive platform from which the PDE divestook place. The majority of PDE dive profiles were collected fromliveaboards (57 percent). This subgroup represents a valuabledataset of repetitive and multiday diving exposures. Thirty-fourpercent of dives were collected on charter boats that take diversfor one day or half-day trips. Only 3 percent of the PDE diveswere walk-in beach dives, and 4 percent were dives from smallprivate boats.30DAN’s <strong>Report</strong> on Decompression Illness, Diving Fatalities and Project Dive Exploration: 2005 Edition
