Journal of RespirationBackground: DLco remains one of the most commonly performed tests in the pulmonary lab. An isolated reduction in DLco is a unique abnormality with specific differentials when evaluating a patient with dyspnea. There remains a significant misunderstanding

DLCO versus DLCO/VA as predictors of pulmonary gas exchange [PDF]
Respiratory Medicine, 2006 The diffusing capacity of the lung is usually reported as both the diffusing capacity (DLCO) and the diffusing capacity divided by the alveolar volume (DLCO/VA). However, it is unclear which measure to use when interpreting pulmonary gas exchange. We therefore conducted this study to determine whether the DLCO or the DLCO/VA is a better predictor of ...

Effect of alveolar volume on the interpretation of single breath DlCO
Respiratory Medicine, 1997 Single-breath carbon monoxide diffusing capacity in the whole lung (DLCO) and per unit alveolar volume (DLCO/VA), as expressed in percentage of normal values, gave discordant results when VA of the patients was abnormal. It was hypothesized that normal reference values were inappropriate to interpret data collected in such patients.

Relevance of partitioning DLCO to detect pulmonary hypertension in systemic sclerosis. [PDF]
PLoS ONE, 2013 We investigated whether partitioning DLCO into membrane conductance for CO (DmCO) and pulmonary capillary blood volume (Vcap) was helpful in suspecting precapillary pulmonary (arterial) hypertension (P(A)H) in systemic sclerosis (SSc) patients with or ...

Relationship between diffusion capacity and small airway abnormality in COPDGene [PDF]
Respiratory Research, 2019 Impaired single breath carbon monoxide diffusing capacity (DLCO) is associated with emphysema. Small airways disease (SAD) may be a precursor lesion to emphysema, but the relationship between SAD and DLCO is undescribed. We hypothesized that in mild COPD,

Measurement of gas exchange surface area from DLNO and DLCO
Respiratory Physiology & NeurobiologyThe estimated diffusion coefficients for nitric oxide and carbon monoxide in human plasma and red cells can be inserted into the equations for Fick's 1st and 2nd laws. The surface area of the alveolar membrane and exposed red cells can then be calculated from DLNO and DLCO (in hyperoxia).

The diffusing capacity of the lungs for carbon monoxide - an independent predictor of interstitial lung disease in patients with rheumatoid arthritis - results of a prospective study [PDF]
Romanian Journal of Rheumatology, 2023 Background. The diffusing capacity of the lungs for carbon monoxide (DLCO) represents the most sensitive independent factor for highlighting the interstitial lung disease associated with rheumatoid arthritis (RA-ILD).

Predictors of fatigue severity in early systemic sclerosis: a prospective longitudinal study of the GENISOS cohort. [PDF]
, 2011 ObjectivesLongitudinal studies examining the baseline predictors of fatigue in SSc have not been reported. Our objectives were to examine the course of fatigue severity over time and to identify baseline clinical, demographic, and psychosocial predictors
