Although asthma is very common, affecting 5–10% of the population, the diagnosis of
asthma in adults remains a challenge in the real world, which results in both over- and under-…

Study objectives To evaluate the use of the FEV 1 /forced expiratory volume at 6 s of exhalation
(FEV 6 ) ratio and FEV 6 as an alternative for FEV 1 /FVC and FVC in the detection of …

We investigated ventilation inhomogeneity in patients with chronic obstructive pulmonary
disease (COPD) through use of the multiple breath N 2 washout test (MBW). From an alveolar …

OBJECTIVES: To estimate the prevalence of undiagnosed chronic obstructive pulmonary
disease (COPD) in a population of general practice patients at risk for developing COPD. A …

The purpose of this study was to determine fixed cut-off points for forced expiratory volume
in one second (FEV 1 )/FEV 6 and FEV 6 as an alternative for FEV 1 /forced vital capacity (FVC…

We investigated acinar airway involvement in 20 patients with stable asthma, using the
phase III slope analysis of the multiple breath N 2 washout previously applied in a group of …

Rationale Small airways function studies in lung disease have used three promising multiple
breath washout (MBW) derived indices: indices of ventilation heterogeneity in the acinar (S …
