DLCO


Also found in: Acronyms, Wikipedia.

carbon monoxide diffusing capacity

A clinical test which provides an objective measure of lung function. It reflects the lung's ability to take up an inhaled nonreactive test gas—e.g., carbon monoxide (CO)—which binds to haemoglobin with such a high affinity that virtually all of the CO reaches the alveolar space. The CO crosses the alveolar air-blood barrier, reaching the red cells, binds to haemoglobin and is removed with the exhaled gas.

DLCO

diffusion capacity of the lung.

(5) In our study, DLCO is significantly lower in PLCH patients with a clinical diagnosis of PHT than PLCH patients without PHT, confirming similar results in previous studies.
All the patients of mean age 28.76667 years, were properly matched with no significant difference with respect to age, sex, height, weight, BMI, spirometric parameters (DLCO) and baseline functional exercise capacity (6MWT), and baseline clinico-physiological parameters e.g.

Inversely, the present study showed that subjects with ACO shared the similar biological characteristics of asthma such as hypereosinophilia, increased total IgE, and high levels of FENO but also the functional characteristics of COPD such as distal airflow limitation, significant decreased DLCO, and low levels of 6MWD and V[O.sub.2] max (Table 2).
No significant correlations between sCD163 levels and any clinical or laboratory variables could be found, including duration of the disease, mRSS, EScSG-AI score, FVC, DLCO, CRP, or ESR.
DLCO is often mildly reduced and does not normalize following heart transplantation.

Segun la serie de la Liga Europea contra el Reumatismo (EULAR) de 2007 (6), en la variedad difusa 53,4% tenian fibrosis pulmonar; 49,3%, compromiso restrictivo y 64%, alteracion de la difusion de monoxido de carbono (DLCO); en cambio, en la variedad limitada 34,7% tenian fibrosis pulmonar; 26,7%, defecto restrictivo y 71,8%, disminucion de la DLCO.
Hence, This study was undertaken to assess whether petrol pump workers expose to air pollutants have changes in pulmonary function tests (PFTs) and to evaluate the diffusing capacity of lungs for carbon monoxide (DLCO) and changes in hematological parameters such as hemoglobin (Hb) and packed cell volume (PCV) of the study group.
PFTs and carbon monoxide diffusion capacity (DLCO) were measured with a Zan 100 (nSpire Health Inc., Oberthulba, Germany) PFT device.
Study subjects were adults aged 18-69 years with mean baseline modified Rodnan skin score of 30, mean baseline forced vital capacity of 74%, and mean diffusing capacity of the lung for carbon monoxide (DLCO) of 53% of predicted.
Pulmonary function testing (PFT) revealed an FEV1/FVC ratio of 98% with diffusion capacity of carbon monoxide (DLCO) 71%.
