Early Progressive Peripheral Airway Dysfunction after Allogeneic Haematopoietic Stem Cell Transplantation is associated with chronic Graft vs Host disease not BOS-0p Open
Background Current spirometric-based criteria for diagnosis of bronchiolitis obliterans syndrome (BOS) may miss early peripheral airway disease associate with disease onset. Multiple breath washout (MBW) and oscillometry offer improved sen…

Controlled<i>versus</i>free breathing for multiple-breath nitrogen washout in asthma Open
The lack of comparability in indices of ventilation heterogeneity between free- and controlled-breathing MBNW protocols is confirmed in asthma https://bit.ly/3lmri4A.

Within-session variability as quality control for oscillometry in health and disease Open
Oscillometry is increasingly adopted in respiratory clinics, but many recommendations regarding measurement settings and quality control remain subjective. The aim of this study was to investigate the optimal number of measurements and acc…

Long-term variability of oscillatory impedance in stable obstructive airways disease Open
FOT parameters have good long-term repeatability in patients with stable obstructive airways disease, facilitating its ability to detect sensitive changes in airways disease. Novel cut-off values presented may help determine clinically …

Controlled<i>versus</i>free breathing for multiple breath nitrogen washout in healthy adults Open
Multiple breath nitrogen washout (MBNW) quantifies ventilation heterogeneity. Two distinct protocols are currently used for MBNW testing: “controlled breathing”, with targeted tidal volume ( V T ) and respiratory rate (RR); and “free breat…

Contribution of peripheral airway function to changes in FEV<sub>1</sub>/FVC and RV/TLC with aging Open
Multiple breath nitrogen washout (MBNW) indices provide insight into ventilation heterogeneity globally [lung clearance index (LCI)] and within acinar (S acin ) and conducting (S cond ) airways. Normal aging leads to an accelerated deterio…

Measurement duration impacts variability but not impedance measured by the forced oscillation technique in healthy, asthma and COPD subjects Open
The forced oscillation technique (FOT) is gaining clinical acceptance, facilitated by more commercial devices and clinical data. However, the effects of variations in testing protocols used in FOT data acquisition are unknown. We describe …
