Spoke with two of the people who were on the boat at DEMA. The diver was running 1.4 ATA, diving around 130-140 which would put his EAD shallower than his actual depth. Deep, but not excessively so. He did have some extended bottom times and did at least two decompression dives per day. One of the divers I spoke with was thinking that he had pulmonary O2 toxicity, but from the description, the symptoms sounded more like pulmonary DCS to me. He had cutis marmorata, which is often accompanied by more severe DCS symptoms. The diver was also significantly overweight.
There's a temptation, when you're in an exotic, once-in-a-lifetime place, to take full advantage of the time you're there and maximize your dives. We recommend an "off-gassing" day halfway through a week-long trip, especially when it involves long, deep dives. Go do an easy hike, snorkel, whatever, but don't breathe compressed air. This will significantly reduce the risk of DCS.
