Central nervous system decompression sickness:latency of 1070 human cases
decompression sickness neurological hyperbaric human spinal cord
2009/7/10
Many aspects of central nervous system (CNS) decompression sickness (DCS) are poorly understood, including the temporal pattern of its presentation and the pathogenic mechanisms involved in the develo...
Manifestations and treatment of 793 cases of decompression sickness in a compressed air tunneling project in Hong Kong
decompression sickness air commercial
2009/7/10
In the largest compressed air tunneling contract for the construction of the Island Line of the Mass Transit Railway system in Hong Kong, 154,390 man-decompressions occurred, of which 142,140 were aft...
Air vs. He-O2 recompression treatment of decompression sickness in guinea pigs
decompression heliox model air animal guinea pigs
2009/7/10
Air vs. He-O2 (20.9% O2) recompression treatment was examined in a model of severe decompression sickness (DCS) using male albino guinea pigs (Cavia porcellus, 500-600 g). Following decompression to t...
Treatment of decompression sickness with a perfluorocarbon emulsio
decompression sickness perfluorocarbon emulsion Sprague-Dawley rat
2009/7/9
Decompression sickness is caused by the production of tissue and blood stream inert gas bubbles. Perfluorocarbon emulsions (PFC) have enhanced O2 and N2 solubilities as well as a small particle size a...
Arterial gas embolism as a pathophysiologic mechanism for spinal cord decompression sickness
decompression Arterial gas embolism spinal cord animal dog
2009/7/9
A continuous infusion of air (1.0 ml.min-1) was delivered via a fine aortic cannula into the arterial circulation of 7 anesthetized dogs until no spinal cord function could be elicited by somatosensor...
Analysis of some individual risk factors for decompression sickness in Hong Kong
decompression sickness risk factors air commercial
2009/7/9
Individual risk factors for decompression sickness (DCS) were studied in 932 men who had worked for 12 shifts or more at maximum working pressure (MWP) of 1 bar or above in a compressed air tunneling ...
Complement activation involvement in decompression sickness of rabbits
decompression Complement activation acclimatization air rabbit animal
2009/7/9
A hypothesis has been proposed that claims much of the phenomena of decompression sickness (DCS) are mediated by the complement system of blood plasma. This "complement hypothesis" can be used to expl...
Ethanol and venous bubbles after decompression in humans
decompression Ethanol human alcohol
2009/7/9
We exposed 34 subjects to a 48-h, 6.25-msw dive, and administered ethanol (0.5-1.0 ml pure ethanol.kg-1 body weight) orally to 11 of them immediately after direct decompression. Doppler monitoring of ...
Microbubble damage to the blood-brain barrier: relevance to decompression sickness
decompression pulmonary blood brain barrier bubbles animal Guinea Pigs
2009/7/8
Decompression sickness affecting the nervous system is still a serious problem in diving, but the mechanisms involved are in dispute. Although microbubbles can be detected in the pulmonary artery on d...
Decompression comparison of N2 and O2 in rats
decompression comparison outcomes animal rat nitrogen oxygen elimination
2009/7/8
We have previously reported that O2 in the breathing gas mixture contributed significantly to the risk of decompression sickness (DCS) in rats after rapid (less than 10 s) decompression to the surface...
Breath-by-breath monitoring of respiratory gas concentrations during compression and decompression
CO2 carbon dioxide equipment decompression nitrogen hyperbaric chamber
2009/7/8
We compared six systems for sampling respiratory gases from within a hyperbaric chamber to provide online gas concentrations by a mass spectrometer (MS) outside the chamber. Gas at hyperbaric pressure...
Simulation of the dynamics of decompression sickness bubbles and the generation of new bubbles
decompression nitrogen bubbles
2009/7/8
This communication introduces a system of equations for simulating the dynamics of growth and decay of decompression bubbles. The equations are solved by a numerical method and account for gas diffusi...
Lidocaine as an adjunct to hyperbaric therapy in decompression illness: a case report
decompression hyperbaric therapy Lidocaine
2009/7/8
A recreational scuba diver with nervous system decompression illness had a poor response to hyperbaric therapy. On the basis of available and supportive in vivo data, he was then given a continuous in...
Intravascular bubble composition in guinea pigs: a possible explanation for differences in decompression risk among different gases
decompression decompression sickness breathing gas bubble animal guinea pig rat
2009/7/8
Differences in risk of decompression sickness (DCS) that have been observed among inert gases may reflect differences in gas solubility or diffusivity or both. A higher risk gas might generate a large...
Effect of severity, time to recompression with oxygen, and re-treatment on outcome in forty-nine cases of spinal cord decompression sickness
decompression sickness outcomes recompression spinal cord treatment re-treatment case reports human
2009/6/12
For systematic study of the effects of clinical severity, time to recompression with oxygen, and re-treatment on outcome from spinal cord DCS, case records from the recompression chamber at the U.S. N...
