EpistemisDLCO Corrected by Hemoglobin and KCO Coefficient
A low DLCO in an anemic patient may just be anemia. The Cotes correction, recommended by ATS/ERS, separates the membrane defect from the transport defect, and the KCO indicates whether the drop is due to volume loss or interstitial disease.
Required inputs
| Variable | Example value |
|---|---|
| DLCO measurement (mL/min/mmHg) | 18 |
| Predicted DLCO (mL/min/mmHg) | 26 |
| Hemoglobin (g/dL) | 10 |
| Sex and age | — |
| Alveolar volume (liters) | 4.5 |

This page explains the score but does not run it. In Epistemis, the calculator validates units, flags values outside physiological ranges, and provides the interpretation that a number alone cannot convey.
Epistemis is educational review material. It is not a medical device, does not diagnose or prescribe treatment, and does not replace formal medical training, current clinical guidelines, or professional clinical judgment.
