WebThe pressure gradient for carbon dioxide between blood and gas is less than that for oxygen. The partial pressure of carbon dioxide in the body is usually low (the venous partial pressure of carbon dioxide, Pvco2, is 45 to 55 torr), so that the pressure difference between the blood and gas phase in the oxygenator is much less than it is for oxygen. WebA concentration gradient occurs when the concentration of particles is higher in one area than another.

WebMay 1, 1989 · An analysis of a particle specifically in an electrolyte, as yet incomplete (1), leads to identical results. In principle, a system can vary with respect to temperature (e.g., the thermal gradient experiments of Young et al. (7)) and pressure (in a gravitational or cen- trifugal field), as well as to chemical composition, when selected terms in Eq. The term typically applies in electrochemistry, when electrical energy in the form of an applied voltage is used to modulate the thermodynamic favorability of a chemical reaction. In a battery, an electrochemical potential arising from the movement of ions balances the reaction energy of the electrodes. The maximum voltage that a battery reaction can produce is sometimes called the standard electrochemical potential of that reaction.
