Probabilistic modelling for estimating gas kinetics and decompression sickness risk in pigs during H2 biochemical decompression.
We modelled the kinetics of H2 flux during gas uptake and elimination in conscious pigs exposed to hyperbaric H2. The model used a physiological description of gas flux fitted to the observed decompression sickness (DCS) incidence in two groups of pigs: untreated controls, and animals that had received intestinal injections of H2-metabolizing microbes that biochemically eliminated some of the H...
متن کاملModulation of decompression sickness risk in pigs with caffeine during H(2) biochemical decompression.
In H(2) biochemical decompression, H(2)-metabolizing intestinal microbes remove gas stored in tissues of animals breathing hyperbaric H(2), thereby reducing decompression sickness (DCS) risk. We hypothesized that increasing intestinal perfusion in pigs would increase the activity of intestinal Methanobrevibacter smithii, lowering DCS incidence further. Pigs (Sus scrofa, 17-23 kg, n = 20) that i...
متن کاملBrain multi-infarct and decompression sickness
Scuba diving is associated with an important risk of developing decompression sickness secondary to formation of gas bubbles inside the body. The latter is formed mainly by nitrogen in the body on the diver’s way to the surface (1,2). In some cases, it might injure the central nervous system. Several decompression cases that have been associated with neurologic symptoms are described in the l...
متن کاملDetection of leukocyte activation in pigs with neurologic decompression sickness.
BACKGROUND In a porcine model of neurological decompression sickness (DCS), perivascular leukocyte activation was a consistent finding in biopsies of associated cutaneous DCS. This prompted examination of other organs for similar changes; multifocal leukocyte activation was found in the lungs (pneumonitis) and liver (hepatitis). HYPOTHESIS DCS in pigs induces leukocyte aggregation and activat...
متن کاملGoodbye Decompression Sickness
by T.J.R. Francis, D.J. Smith and J.J. W. Sykes, Institute of Naval Medicine, Hampshire, England. The current means by which we classify decompression sickness dates back only 30 years to the experience gained during the construction of the Dartford Tunnel in London. Golding et al [1] proposed a system for decompression sickness based upon perceived severity of the cases which arose in the cais...
