Helium at pressures of 20 to 70 atm in the presence of air found to stimulate growth of Streptococcus faecalis, Escherichia coli, and Staphylococcus aureus, mainly by increasing the rate of exponentia...
Influence of nitrous oxide, nitrogen, neon, and helium on the beating frequency of the mouse sinus node at high pressure
cardiac animal mice nitrous oxide nitrogen neon helium sinus node
2009/7/17
The beating frequency (BF) reducing effect of 150 atm of hydrostatic pressure on mammalian cardiac pacemaker tissue (hyperbaric bradycardia) was counteracted by dissolved gas only if the gas was added...
Narcotic effects of nitrous oxide and compressed air on memory and auditory perception
human Narcotic perception air nitrous oxide
2009/7/17
Three experiments were conducted to examine the effects of 35percent N2 O (nitrous oxide) on human memory and auditory perception. In Experiment I, dichotic listening performance was found to be impai...

While the ability of increased pressure to reverse anaesthesia has been well documented, the cellular or molecular mechanism(s) responsible for their mutual antagonism have remained elusive.
Arterial baroreflex control during mild-to-moderate nitrous oxide narcosis
saturation narcosis hyperbaric air
2009/6/8
We hypothesized that light-to-moderate inert gas narcosis might play a role in bradycardia in divers by altering sensitivity or response dynamics of arterial baroreflexes. Carotid-cardiac and carotid-...
