Breath tests cover the fraction of nitric oxide in expired gas (F ENO), volatile organic
compounds (VOCs), variables in exhaled breath condensate (EBC) and other …

PURPOSE: To determine the test performance and longitudinal evolution of air trapping for
diagnosing bronchiolitis obliterans syndrome (BOS). MATERIALS AND METHODS: Over 7 …

Controlled studies have shown that monitoring of the exhaled nitric oxide fraction (F eNO)
improves asthma management. However, the studies seldom consider the full range of …

When heated by an electronic cigarette, propylene glycol and glycerol produce a nicotine-
carrying-aerosol. This hygroscopic/hyperosmolar aerosol can deposit deep within the lung …

Ventilation distribution during histamine provocation. J. Appl. Physiol. 83 (6): 1907–1916 …

We investigated ventilation inhomogeneity in patients with chronic obstructive pulmonary
disease (COPD) through use of the multiple breath N2 washout test (MBW). From an …

Background Few data are available on the long-term effect of pulmonary rehabilitation (PR)
and on long PR programs in interstitial lung diseases (ILD). We aimed to evaluate the effects …

We investigated acinar airway involvement in 20 patients with stable asthma, using the
phase III slope analysis of the multiple breath N2 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 …

Background The increased fraction of exhaled nitric oxide (F eno) values observed in
asthmatic patients are thought to reflect increased airway inflammation. However, F eno …
