CNS reactions at 51 ATA on trimix and heliox and during decompression
human trimix heliox
<
2009/7/14
Two groups of divers (Group A and B) were compressed to 500 msw with trimix (n = 3) and heliox (n = 3). After 4 d at saturation depth Group A had a gas change to heliox. Both groups were followed with...
CNS oxygen toxicity in the rat: role of ambient illumination
hyperbaric CNS oxygen toxicity Central Nervous System animal rat
<
2009/7/14
The effect of ambient illumination on sensitivity to CNS oxygen toxicity was studied in awake male rats. Continuous recording of the EEG was obtained with chronically implanted cortical electrodes. Th...
CNS oxygen toxicity in oxygen-inert gas mixtures

<
2009/7/14
Central nervous system oxygen toxicity in hyperbaric oxygen-inert gas mixtures was studied by exposing male rats to various gas mixtures having the same oxygen partial pressure and varying pressures o...
Visual reaction time performance preceding CNS oxygen toxicity

<
2009/7/14
The visual reaction time performance of divers experiencing CNS oxygen toxicity was assessed during the development of closed-circuit 100percent oxygen breathing diving schedules at the U.S. Navy Expe...
Experimental determination of latency, severity, and outcome in CNS decompression sickness

2009/6/2
Exposure to high pressures (HP) has been associated with the development of the high pressure neurological syndrome (HPNS) in deep-divers and experimental animals. In contrast, many diving mammals are...
Magnesium sulfate suppresses electroencephalographic manifestations of CNS oxygen toxicity

<
2009/3/26
We studied the effects of parenteral magnesium sulfate (MgSO4) administration on electroencephalographic seizures induced by hyperbaric oxygen (HBO) in awake rats. Sixteen rats chronically implanted ...
Statistical approach to the analysis of sensitivity to CNS oxygen toxicity in rats
