Narcosis and Emulsion Reversal by Inert Gases
Investigations of the effect of high pressures of Na (100 to 130 atmospheres) and of Ar (60 to 80 atmospheres) showed that these gases are effective in reversing the phases of an oil in water emulsion. Nitrous oxide did not cause reversal at pressures as high as 53 atmospheres nor did helium as high as 107 atmospheres. We found CO(2) most effective in reversing the emulsions and attributed this...
متن کاملRecent neurochemical basis of inert gas narcosis and pressure effects.
Compressed air or a nitrogen-oxygen mixture produces from 0.3 MPa nitrogen narcosis. The traditional view was that anaesthesia or narcosis occurs when the volume of a hydrophobic site is caused to expand beyond a critical amount by the absorption of molecules of a narcotic gas. The observation of the pressure reversal effect on general anaesthesia has for a long time supported the lipid theory....
متن کاملA review of recent neurochemical data on inert gas narcosis.
Nitrogen narcosis occurs in humans at around 0.4 MPa (4 ATA). Hydrogen narcosis occurs between 2.6 and 3.0 MPa. In rats, nitrogen disturbances occur from 1 MPa and a loss of righting reflex around 4 MPa. Neurochemical studies in striatum of rats with nitrogen at 3 MPa (75% of anesthesia threshold) with differential pulse voltammetry have demonstrated a decrease in dopamine (DA) release by neuro...
متن کاملThe Uptake of Inert Gases in Diving
where Pabs is the absolute pressure and FtN2 is the fractional concentration of N2. If a diver, breathing 20% oxygen and 80% nitrogen, swims down to 30 MSW the inspired PN2 (PiN2) is calculated from equation 1 as: PiN2 = 4 bars x 0.8 = 3.2 bars. The lung alveolar PN2 (PAN2) will be slightly lower than this, but for the sake of simplicity we will assume that it also is 3.2 bars. The venous blood...
متن کاملAnharmonicity and potentials for the solidified inert gases
The parameters for a representative two-body Morse potential are determined for the solidified inert gases by fitting to O'K solid data. This is done using first the harmonic approximation and subsequently the first-order self-consistent harmonic approximation, which provides an upper limit to the anharmonic correction, to describe the solid at O'K. On comparing the two cases, the effect on the...
