  • concentration
  • Given sufficient time at a specific partial pressure in the breathing gas, the concentration in the tissues will stabilise, or saturate, at a rate depending on the solubility, diffusion rate and perfusion. (wikipedia.org)
  • However, during a reduction in ambient pressure, the rate of pressure reduction may exceed the rate at which gas can be eliminated by diffusion and perfusion, and if the concentration gets too high, it may reach a stage where bubble formation can occur in the supersaturated tissues. (wikipedia.org)
  • respiratory

(google.es)
  • ambient
  • ambient pressure Pressure of the surroundings. (wikipedia.org)
  • The uptake of gas by the tissues is in the dissolved state, and elimination also requires the gas to be dissolved, however a sufficient reduction in ambient pressure may cause bubble formation in the tissues, which can lead to tissue damage and the symptoms known as decompression sickness, and also delays the elimination of the gas. (wikipedia.org)
  • Decompression modeling attempts to explain and predict the mechanism of gas elimination and bubble formation within the organism during and after changes in ambient pressure,and provides mathematical models which attempt to predict acceptably low risk and reasonably practicable procedures for decompression in the field. (wikipedia.org)
  • Gas is breathed at ambient pressure, and some of this gas dissolves into the blood and other fluids. (wikipedia.org)
  • Decompression
  • In all cases, the symptoms caused by decompression occur during or within a relatively short period of hours, or occasionally days, after a significant pressure reduction. (wikipedia.org)
  • Although recompression and slow decompression were the accepted treatment, there was not yet a standard for either the recompression pressure or the rate of decompression. (wikipedia.org)

  • The vapor pressure chart displayed has graphs of the vapor pressures versus temperatures for a variety of liquids. (wikipedia.org)
  • As can be seen in the chart, the liquids with the highest vapor pressures have the lowest normal boiling points. (wikipedia.org)
  • It also has the lowest normal boiling point (-24.2 °C), which is where the vapor pressure curve of methyl chloride (the blue line) intersects the horizontal pressure line of one atmosphere (atm) of absolute vapor pressure. (wikipedia.org)
  • equilibrium
  • Fugacity is another predictive criterion for equilibrium among phases that has units of pressure. (wikipedia.org)
  • Eventually it reaches a new dynamic equilibrium state, with a much lower partial pressure of CO2 in the headspace and thus a much lower amount of CO2 held in solution. (wikipedia.org)
  • lower
  • The integral dual-detector enables monitoring at high pressure by Faraday detector and at lower pressures to UHV by electron multiplier detector, giving full conventional RGA specification with partial pressure detection down to 2x10E-13 torr and a total dynamic range in excess of 10 decades. (technologynetworks.com)
  • In other words, the larger oxygen window due to a higher oxygen partial pressure can allow the diver to decompress faster at a shallower stop at the same risk, or at the same rate at the same depth at a lower risk, or at an intermediate rate at an intermediate depth at an intermediate risk. (wikipedia.org)
  • Sequential or multistage pumping can be used to attain lower pressures. (wikipedia.org)
  • mixture
  • The portion of the total gas pressure exerted by a single gas in a breathing mixture, expressed as Pg for an unknown gas or PO2 in the case of Oxygen. (gooddive.com)

  • decrease
  • Rohrig also observes from experiment that the Fizz Keeper forms a poorer seal than the bottle's own screw cap, thus allowing CO2 to leak out, and the CO2 partial pressure to decrease, more quickly with the Fizz Keeper on a bottle than with the normal cap. (wikipedia.org)
  • chamber
  • Most treatment protocols for diving injuries require an attendant in the chamber, and a medical lock to transfer medical supplies into the chamber while under pressure. (wikipedia.org)
  • cause
  • This alone is enough to cause a blackout, but it is widely believed that the effect is enhanced if lung air pressure is increased by holding the breath "hard" or "bearing down" (tightening the diaphragm as in a forced exhalation while allowing no air to escape or having an assistant apply a bear-hug). (wikipedia.org)
