Effect of preinspiratory maneuver on the single-breath DLCO.
American Journal of Respiratory and Critical Care Medicine, 1995We have observed in some patients with pulmonary disease and normal subjects that the difference between two successive measurements for single-breath DLCO amounted to 10%. By scrutinizing data from these subjects, we observed that they spontaneously changed their preinspiratory maneuver just before inhaling the test gas mixture.

Measurement of lung volume and DLCO in acute respiratory failure.
American Journal of Respiratory and Critical Care Medicine, 1994We have undertaken rebreathing measurements of functional residual capacity (FRC), carbon monoxide diffusing capacity (DLCO), and diffusing coefficient (KCO) during positive pressure ventilation in 15 patients with adult respiratory distress syndrome (ARDS).

Effect of ventilation and diffusion nonuniformity on DLCO (exhaled) in a lung model
Journal of Applied Physiology, 1980Recent studies have shown that diffusing capacities measured at multiple intervals during a single exhalation [DLCO(exhaled)] remained constant with lung volume in normal subjects, but decreased with decreasing lung volume in patients who may have had diffusion nonuniformity.

Long-term stability of a portable DLCO instrument
9.1 Respiratory Function Technologists/Scientists, 2015Introduction: 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, 2019Introduction: 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 ...

Interpretation of changes in DlCO and pulmonary function after running five miles
Respiration Physiology, 1986The 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.

Test of independence between the membrane and the blood components of DLCO
Respiratory Function Technologists/Scientists, 2017Lung diffusing capacity for carbon monoxide, DLCO, has been interpreted by the Roughton-Forster (RF) equation. The equation decomposes the total resistance for the CO capture into the sum of two in series, the membrane and the blood resistances: 1/DLCO = 1/DMCO + 1/(θCO·Vc) where θCO is the specific conductance for CO transfer in the red cell and Vc is

Predictors For Longitudinal Change In DLCO In A Community Based Sample
D59. COPD EPIDEMIOLOGY: RISK FACTORS, TRENDS, COMORBIDITIES, 2012RATIONALE: 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.
