Long-term stability of a portable DLCO instrument

9.1 Respiratory Function Technologists/Scientists, 2015
Introduction: The ATS+ERS guidelines for DLCO recommends a weekly biological control (bio-QC) or DLCO simulator to detect instrument errors or drift. Very little has been published regarding the results of such a quality assurance program. Methods: We used a new ndd EasyOne Pro system, and checked its accuracy using a Hans Rudolph simulator testing

Reducing the variability of DLCO measurements in clinical trials

Monitoring airway disease, 2019
Introduction: Measuring diffusing capacity of the lung for carbon monoxide (DLCO) facilitates the diagnosis, classification and monitoring of various lung diseases, and may also be used for safety signal detection in clinical drug development. However, other factors such as exercise, supine position, and diurnal variations may affect the gas transfer ...

Effect of breath-hold time on DLCO(SB) in patients with airway obstruction.

Journal of applied physiology, 1985
The single-breath diffusing capacity of the lung for CO [DLCO(SB)] is considered a measure of the conductance of CO across the alveolar-capillary membrane and its binding with hemoglobin. Although incomplete mixing of inspired gas with alveolar gas could

Intraindividual variability in serial measurements of DLCO and alveolar volume over one year in eight healthy subjects using three independent measuring systems.

American Review of Respiratory Disease, 1989
To evaluate intraindividual and between-machine variability in DLCO, one technician performed triplicate measurement of DLCO in eight healthy subjects on three consecutive days using three different systems (Collins [C], Gould [G], SRL [S]) on five ...

Interpretation of changes in DlCO and pulmonary function after running five miles

Respiration Physiology, 1986
The purpose of this study was to evaluate changes in pulmonary function after running five miles. Of particular interest was the reaffirmation of the previously reported 'uncoupling' or dissociation of pulmonary diffusing capacity (DLCO) and cardiac output (Q) after moderate or strenuous exercise.

Predictors For Longitudinal Change In DLCO In A Community Based Sample

D59. COPD EPIDEMIOLOGY: RISK FACTORS, TRENDS, COMORBIDITIES, 2012
RATIONALE: Data on the change in diffusion capacity for carbon monoxide (DLCO) over time is limited. Based on a community sample we aimed to examine the change in DLCO (ΔDLCO) over a 9 year period and predictors for this change. METHODS: A Norwegian stratified general population sample comprising 1152 subjects aged 18-72 years was examined in 1987/88.
