WebWhat increases diffusing capacity of oxygen? Indeed, with vigorous exercise, D LO2 increases from 20-30 ml/min/mmHg to something close to 100-120 ml/min/mmHg, which is the real capacity for diffusion. This increase is because the oxygen uptake rate in the equation (D LO2 = oxygen uptake / PO 2 gradient) increases significantly. WebJun 5, 2012 · Diffusing capacity The diffusing capacity is a measure of the abil - ity of the lungs to transfer gas.3,4 Diffusion in the lungs is most efficient when the surface area for gas transfer is high and the blood is readily able to accept the gas being transferred. It is thus decreased in: • Conditions that minimize the ability of eas1111
