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.
