May 1, 2025 · The suggested diagram using measurements of diffusing capacity can specify the clinical relevance of DL CO, D’L CO, K CO, and V A. Fig. 5 presents the differential diagnosis in patients …

The initial reaction product is a 50:50 mixture of E and Z isomers but because both isomers equilibrate rapidly around their common hydroxyl precursor, the more stable Z-isomer can eventually be obtained.

In D (Airflow obstruction), TLC is normal and V A is reduced because the inhaled CO only reaches the better ventilated parts of the lung; therefore, the K CO is probably an "optimistic" or upper-bound value.

A low D aco (percent predicted) indicates the lung’s diffusion capacity when adjusted for lung volume is low. This can occur with interstitial lung disease (ILD), emphysema, or pulmonary vascular disease.

Knoevenagel Condensation is an organic reaction named after Emil Knoevenagel. It is a classic C-C bond formation reaction and a modification of the Aldol Condensation.
