Heliox treatment for spinal decompression sickness following air dives
spinal decompression sickness air Heliox
2009/7/10
Enforced delay in treatment of spinal decompression sickness following scuba diving can result in paraplegia. Poor response from initial recompression to 18 m presents the clinician with a difficult m...
Experimental determination of latency, severity, and outcome in CNS decompression sickness
decompression sickness neurological outcomes animal dog
2009/7/10
Twenty-eight dogs underwent a 300 fsw chamber dive designed to generate spinal cord decompression sickness (DCS), which was detected by observing a reduction in the amplitude of the spinal somatosenso...
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...
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...
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...
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...
Spinal decompression sickness:hydrophobic protein and lamellar bodies in spinal tissue
decompression animal sheep
2009/6/12
Four basic studies have addressed the question of why the spinal cord is so vulnerable to decompression injury, with symptoms exceeding those related to the brain by a ratio often quoted as 3:1. Hydro...
Oxy-helium treatment of severe spinal decompression sickness after air diving
spinal decompression sickness HBO air heliox
2009/6/12
Spinal cord injury in DCS after air diving is relatively frequent and often has late sequelae. U.S. Navy oxygen tables are sometimes not satisfactory. The advantage of using helium in these cases is b...
Protective effect of oxygen and heliox breathing during development of spinal decompression sickness
decompression sickness helium heliox oxygen spinal cord animal rat air
2009/6/12
A rat model of spinal decompression sickness (DCS) allows study of spinal cord function for at least 3 h after decompression to 1 atm abs (101 kPa) after an exposure to air at 3.8 atm abs (385 kPa) fo...
