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.

Pulmonary vascular volume is associated with DLCO and fibrotic score in idiopathic pulmonary fibrosis: an observational study [PDF]

BMC Medical Imaging, 2022
Background Idiopathic pulmonary fibrosis (IPF) is a disease that primarily occurs in elderly individuals. However, it is difficult to diagnose and has a complex disease course.

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).

Different KCO and VA combinations exist for the same DLCO value in patients with diffuse parenchymal lung diseases [PDF]

BMC Pulmonary Medicine, 2015
BackgroundDLCO is the product of the CO transfer coefficient (KCO) by the “accessible” alveolar volume (VA). In theory, the same DLCO may result from various combinations of KCO and VA values, each of which reflect different injury sites and mechanisms ...

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.

Predictive value of isolated DLCO reduction in systemic sclerosis patients without cardio-pulmonary involvement at baseline

Reumatismo, 2016
Impaired diffusing capacity of the lung for carbon monoxide (DLCO) was frequently observed in systemic sclerosis (SSc) patients, generally related to the presence of interstitial lung disease (ILD) and/or pulmonary arterial hypertension (PAH).

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.

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 ...
