Hyperbaric inert gases and the hemoglobin-oxygen equilibrium in red blood cells
human Erythrocytes hemoglobin red blood cell inert gas helium nitrogen
2009/7/20
Hyperbaric inert gases and the hemoglobin-oxygen equilibrium in red blood cells.
Data have been tabulated from more than 150 references on the solubility of inert gases in fluids and tissues of biological interest. Thirty-two gases have been studied in blood with measured solubili...
Patterns of interaction of effects of light metabolically inert gases with those of hydrostatic pressure as such--a review
decompression human animal mice
2009/7/16
This review of available literature attempts to interpret net effects of metabolically inert light gases (He, H2, and Ne) as the resultant of hydrostatic pressure and intrinsic pharmacological effects...
Reversal of pressure-induced tremors in rats by step decompression and by inert gases
decompression animal mice
2009/7/15
A method for continuously recording the motor activity of pressurized rats was used to monitor their condition after 1) holding pressure constant after compression, 2) decompression, and 3) adding nit...
Free radical reactions and the inhibitory and lethal actions of high-pressure gases
superoxide dismutase Free radical paraquat methyl viologen Escherichia coli
2009/7/14
This study was designed to test whether free radicals are involved in the deleterious effects of compressed gases on cells. The actions of xenon, nitrous oxide, argon, nitrogen, helium, and oxygen and...
Components of the pressure required to breathe dense gases
human Respiration dense gas lung work of breathing
2009/7/14
To elucidate the impact of high gas density on airway flow (during inspiration and expiration) and on gas acceleration (at end-inspiration and end-expiration), I simulated pressures for breathing in m...
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...
CO2 binding by Baralyme in three different carrier gases
scrubber CO2 carbon dioxide model hyperbaric Baralyme Sodasorb rebreather
2009/6/12
The absorptive properties of Baralyme and Sodasorb for CO2 in a container were studied by measuring the lifetime T0.5 of the unit, i.e., the time until the exit concentration of CO2 reaches 0.5%. The ...
Diffusion coefficients and solubility coefficients for gases in biological fluids and tissues: a review
diffusion coefficients literature review
2009/6/8
Based on a review of 166 references for diffusion and solubility coefficients in biological fluids and tissues, we have tabulated experimental values for the gases Ar, CO2, H2, He, N2, Ne, N2O, O2, an...
The authors developed a new apparatus for extracting nitrogen or other inert gases from blood by flushing (sparging) the specimen with another gas. To investigate the utility of the new methodology, t...
Breathing a mixture of inert gases: disproportionate diffusion into decompression bubbles
decompression bubbles diffusion
2009/6/8
To study the consequences of diving with gas mixtures, we simulated growth of decompression bubbles using an equation system that accounts for major determinants of bubble behavior. When breathing a m...
The theory and application of intravascular microbubbles as an ultra-effective means of transporting oxygen and other gases

Gender differences in human skeletal muscle and subcutaneous tissue gases under ambient and hyperbaric oxygen conditions
Hyperbaric Oxygenation gender human skeletal muscle subcutaneous tissue Gas tensions resting conditions
2009/6/2
The purpose of this study is to ascertain if gender differences exist in human skeletal muscle (MM) and subcutaneous (SC) tissue gases using monoplace and multiplace hyperbaric oxygen (HBO2) treatment...
Effects of hydrostatic pressure and inert gases on twitch tension
animal rat twitch inert gas
2009/3/30
Effect of pressure and inert gases on the twitch tension (Tmax) was measured on electrically stimulated and spontaneously beating rat atria. In stimulated preparations, pressurization to 10 MPa increa...
