The purpose of this review is to examine the validity of change in the cortical evoked response as a measure of inert gas narcosis in humans. Three criteria are defined which must all be met if a nonb...

Effect of heat and cold stress on inert gas (133xenon) exchange in the rabbit.
The effects of inert gas narcosis on behavior before unconsciousness are reviewed with particular attention to four issues. The first is whether the qualitative behavioral effects of all inert gases a...
Effects of ethanol and amphetamine on inert gas narcosis in humans
drug human ethanol alcohol narcosis amphetamine
2009/7/14
The effects of ethyl alcohol (1 ml/kg body weight), dextroamphetamine (15 mg), and nitrous oxide (20percent) on reaction time were investigated in 6 subjects with a 2-, 3-, and 4-choice serial reactio...
A study was conducted to examine the vestibular ocular reflex (VOR) during narcosis. The slow phase velocity of the nystagmus was measured in six subjects by means of electronystagmography during the ...
Hypothermia impairs but hyperthermia does not promote inert gas elimination in the rat
hypothermia hyperthermia inert gas elimination animal rat

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...
Effects of inert gas narcosis on rehearsal strategy in a learning task
model narcosis learning adaptation
2009/7/14
Two experiments were conducted to examine the effects of 35% nitrous oxide (N2O) on rehearsal strategy while learning a list of words in a free-recall paradigm. In experiment 1, the subjects learned t...
Relationship between the event-related brain potential P300 and inert gas narcosis
narcosis cognitive inert gas narcosis
2009/6/12
It is known that inert gas narcosis slows both reaction time (RT) and the event-related brain potential P300 in a correlated and dose-dependent manner. On the assumption that P300 reflects the time to...
Assay of inert gas contamination in studies of hydrostatic pressure effects
hyperbaric inert gas contamination
2009/6/12
In hyperbaric tissue studies it is common to use gas pressure as a means for increasing the hydrostatic pressure of the preparation. When this is done, one must take the necessary precautions to avoid...
Development and interactions of two inert gas bubbles during decompression
model bubble inert gas
2009/6/8
A mathematical model has been developed to simulate the evolution of two inert gas bubbles in tissue. This is useful for understanding the dynamics of bubbles that presumably arise during decompressio...
