The ERS recommends expressing DLCO in SI units (mmol·min−1·kPa−1) while the ATS prefers traditional units (mL·min −1·mmHg ) under standard temperature, pressure and dry conditions (STPD). Values in SI units can be multiplied by 2.987 to obtain values in traditional units.

1. DLco values should be within 2 mL/min/mmHg (0.67 mmol/min/kPa) of each other. 2. The average of at least two acceptable tests that meet repeatability should be reported. NOTE: Adjustments of DLco for Hb, COHB and altitude should be considered. *A maneuver with an inspired volume of ≥85% of largest vital capacity may be deemed

This document provides an update to the European Respiratory Society (ERS)/American Thoracic Society (ATS) technical standards for single-breath carbon monoxide uptake in the lung that was last updated in 2005.

Although both DLCO (diffusing capacity) and TLCO (transfer factor) are valid terms to describe the uptake of carbon monoxide in the lung, the term DLCO is used in this document. A joint taskforce appointed by the ERS and ATS reviewed the recent literature on the measurement of DLCO and surveyed the current technical capabilities of ...

Compensation for end-expiratory gas concentrations prior to test gas inhalation in the calculation of VA and DLCO. Measure anatomic dead-space using the Fowler method. Display a graph of exhaled gas concentration versus volume (not time) to confirm point of dead-space washout and to report the amount of manual adjustment if this was done.

The equation proposed by Cotes and coworkers is currently considered as the most acceptable to correct carbon monoxide diffusing capacity (DLCO) for hemoglobin concentration [Hb] by both the American Thoracic Society (ATS) and the European Respiratory Society (ERS) guidelines for standardization of DLCO.

The single-breath carbon monoxide diffusing capacity (D lCO) is the product of two measurements during breath holding at full inflation: (1) the rate constant for carbon monoxide uptake from alveolar gas (k co [minute −1]) and (2) the “accessible” alveolar volume (V a). k co expressed per mm Hg alveolar dry gas pressure (Pb*) as k co /Pb*, and t...
