“…This finding has medical and logistical relevance for rescue planners. Well-documented human data on air saturation are limited to depths Ͻ30 fsw (1.91 ATA) with apparent and statistically estimated incidence rates well below 50% (28). Human DCS symptoms in that range are mostly pain only, with a few paresthesias, symptoms difficult to detect in swine.…”

Weathersby. Natural history of severe decompression sickness after rapid ascent from air saturation in a porcine model. J Appl Physiol 89: 791-798, 2000.-We developed a swine model to describe the untreated natural history of severe decompression sickness (DCS) after direct ascent from saturation conditions. In a recompression chamber, neutered male Yorkshire swine were pressurized to a predetermined depth from 50-150 feet of seawater [fsw; 2.52-5.55 atmospheres absolute (ATA)]. After 22 h, they returned to the surface (1 ATA) at 30 fsw/min (0.91 ATA/min) without decompression stops and were observed. Depth was the primary predictor of DCS incidence (R ϭ 0.52, P Ͻ 0.0001) and death (R ϭ 0.54, P Ͻ 0.0001). Severe DCS, defined as neurological or cardiopulmonary impairment, occurred in 78 of 128 animals, and 42 of 51 animals with cardiopulmonary DCS died within 1 h after surfacing. Within 24 h, 29 of 30 survivors with neurological DCS completely resolved their deficits without intervention. Pretrial Monte Carlo analysis decreased subject requirement without sacrificing power. This model provides a useful platform for investigating the pathophysiology of severe DCS and testing therapeutic interventions. The results raise important questions about present models of human responses to similar decompressive insults.

“…32 A large fraction of the remaining dives were conducted with divers relatively comfortable under dry conditions. Accordingly, model-estimated DCS risks for the dives tested in present work lie between observed DCS incidence extremes (Figure 6), with large latitude for thermalinduced variation within those extremes.…”

“…i.e., divers wore wet suits (passive thermal protection) and exercised in cold water, then decompressed at rest in water at the same temperature. 32 A large fraction of the remaining dives were conducted with divers relatively comfortable under dry conditions. Accordingly, model-estimated DCS risks for the dives tested in present work lie between observed DCS incidence extremes (Figure 6), with large latitude for thermalinduced variation within those extremes.…”

“…Case 3) Diver 31, Dive: 120/30 W/C, 040903 32 year-old male reported 18 hr post surfacing that his wife had noticed a red rash on his left upper lateral thigh approximately 5 hr after surfacing. Patient noted at that time that the skin in the affected area was red, raised and very "itchy", but without blue discoloration or marbling.…”
