Line 13:

However, because it is difficult to measure the capillary partial pressure of oxygen, carbon monoxide (CO) is used as the test gas to measure the diffusing capacity (Dlco). Because CO is so tightly bound to hemoglobin in the red blood cells, the partial pressure of CO in the capillaries is assumed to be zero. Thus,

:<math>D_LCO = \frac {J^*_{CO}}{P_{ACO2ACO}}</math>
