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 ...

Endoscopic lung volume reduction with endobronchial valves in very low DLCO patients: results from the German Registry – Lungenemphysemregister e.V.

ERJ Open Research, 2021
Background Endoscopic lung volume reduction (ELVR) with valves has been suggested to be the key strategy for patients with severe emphysema and concomitant low diffusing capacity of the lung for carbon monoxide (DLCO).

Endobronchial Valve Treatment in Emphysema Patients with a Very Low DLCO [PDF]

Respiration, 2020
<b><i>Background:</i></b> For selected patients with severe emphysema, bronchoscopic lung volume reduction with endobronchial valves (EBV) is recognized as an additional treatment option. In most trials investigating EBV treatment, patients with a very low diffusing capacity (DLCO) were excluded from participation.

Comparison of diffusing capacity of carbon monoxide (DLCO) and total lung capacity (TLC) between Indigenous Australians and Australian Caucasian adults.

PLoS ONE, 2021
Background and objectiveCurrently there is paucity of evidence in the literature in relation to normative values for diffusing capacity of carbon monoxide (DLCO) and total lung capacity (TLC) among Indigenous Australians. Hence, in this study we assessed

Time-based understanding of DLCO and DLNO

Respiratory Physiology & Neurobiology, 2016
Capture of CO and NO by blood requires molecules to travel by diffusion from alveolar gas to haemoglobin molecules inside RBCs and then to react. One can attach to these processes two times, a time for diffusion and a time for reaction. This reaction time is known from chemical kinetics and, therefore, constitutes a unique physical clock.

DLCO versus DLCO/VA as predictors of pulmonary gas exchange [PDF]

Respiratory Medicine, 2007
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 ...

Lower DLco% identifies exercise pulmonary hypertension in patients with parenchymal lung disease referred for dyspnea

Pulmonary Circulation, 2020
Exercise pulmonary hypertension is an underappreciated form of physical limitation related to early pulmonary vascular disease. A low diffusing capacity of lungs for carbon monoxide (DLco) can be seen in patients with resting pulmonary hypertension as ...

The prognostic value of DLCO and pulmonary blood flow in patients with pulmonary hypertension [PDF]

Pulmonary Circulation, 2019
BackgroundCardiac output is a prognostic marker in patients with pulmonary hypertension. Pulmonary blood flow as a surrogate for cardiac output can be measured non‐invasively by inert gas rebreathing. We hypothesized that pulmonary blood flow can predict outcome in patients with pulmonary hypertension.MethodsFrom January 2009 to January 2012, we ...

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.

Standardization of spirometry and single breath DLCO tests

European Respiratory Journal, 1988
Standards for patient care and especially for pulmonary function testing have become important world wide, especially in the United States [1, 2, 3]. Recently the American Thoracic Society (ATS) has published two new statements.
