Web5. A low value of TLCO must be caused by a low value of KCO or VA or both. The primary measurements must be inspected first. A TLCO of 60% predicted can arise from a variety of combinations of KCO and VA (see later, Tables 3-4 ), each combination having a different clinical connotation. Physiological influences on TLCO and KCO. 1. WebDifferences in results for DLCO cannot be explained by differences in the physiologic state of the animal at the time the measurement was made. Morphometric analysis predicts that Vc is the major term affecting the value of DLCO whereas the physiologic techniques predict that both Dm and Vc contribute substantially to the value of DLCO.
