Compressed air tunneling and caisson work decompression procedures: development, problems, and solutions
decompression commercial air
2009/6/8
Multinational experience over many years indicates that all current air decompression schedules for caisson and compressed air tunnel workers are inadequate. All of them, including the Occupational Sa...
Dibutyryl cAMP effects on thromboxane and leukotriene production in decompression-induced lung injury
decompression neutrophil lung injury
2009/6/8
Decompression-induced venous bubble formation has been linked to increased neutrophil counts, endothelial cell injury,release of vasoactive eicosanoids, and increased vascular membrane permeability.
Spinal cord lipid levels in a porcine model of spinal cord decompression sickness
helium heliox decompression air chamber Spinal cord lipid animal swine
2009/6/8
Spinal cord lipid content was analyzed in 50 pigs that had experienced a simulated dive known to produce 20-80% incidence of neurologic decompression sickness (DCS). Using air and heliox as breathing ...
Diving decompression fails to activate complement
decompression hyperbaric air complement bubble
2009/6/8
The present study evaluated complement activation during decompression after air dives in a hyperbaric chamber. Intravascular bubbles were quantified by Doppler ultrasound scoring. Eighteen subjects c...
Improved probabilistic decompression model risk predictions using linear-exponential kinetics
decompression model air nitrox linear exponential
2009/6/8
Using a data base of 2,383 air and nitrogen-oxygen dives resulting in 131 cases of decompression sickness (DCS), risk functions were developed for a set of probabilistic decompression models according...
Reversibility in blood-brain barrier, microcirculation, and histology in rat brain after decompression
decompressio air animal rat
2009/6/8
To examine the changes in blood-brain barrier (BBB), cerebral microcirculation, and histology from 15 min to 72 h after decompression, 90 rats were exposed to experimental compression to 6 atm abs air...
Risk of decompression sickness with patent foramen ovale
PFO decompression screening patent foramen ovale
2009/6/8
Several reports have described populations of divers with decompression sickness (DCS) who have a patent foramen ovale (PFO). The presence of a PFO is known to occur in about 30% of the normal populat...
Cutaneous lesions in swine after decompression: histopathology and ultrastructure
decompression swineneutrophil model dry chamber animal
2009/6/8
A detailed histopathologic description of skin lesions from a porcine model of decompression sickness (DCS) is presented. Pigs were dived in a dry chamber on a variety of profiles over an 11-mo period...
Evaluation of oxygen and pressure in treatment of decompression sickness in guinea pigs
decompression sickness animal Guinea Pigs recompression therapy treatment
2009/6/8
These experiments examined whether increasing the partial pressure of oxygen (PO2), hydrostatic pressure, or both were responsible for the improvement in effectiveness of recompression treatment previ...
Ocular bubble formation as a method of assessing decompression stress
retinal eye decompression hyperbaric chamber Ocular bubble formati
2009/6/8
Tear film bubble formation and ultrasound reflectivity of the lens-vitreous humor compartments were monitored following simulated dives in a hyperbaric chamber. the sensitivity of these methods in det...
Immune function in hyperbaric environments, diving, and decompression
decompression hyperbaric CD4-CD8 Ratio Complement Immunity Lymphocyte
2009/6/8
The purpose of this review is to examine the influence of exposure to hyperbaric oxygen (HBO2) deep diving, and decompression on various facets of the immune response. Potential changes during exposur...
Effect of anti-C5a antibody on blood-lung and blood-brain barrier in rabbits after decompression
decompression pulmonary complement rabbit animal
2009/6/8
The complement activation product C5a may be an important mediator of tissue injury after decompression stress. This study investigated whether the administration of anti-C5a antibody may reduce chang...
