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.
