Duration impacts variability measured by the forced oscillation in healthy, asthma & COPD subjects
FOT measurements are useful for measuring lung function of people who have difficulty performing spirometry, since it requires tidal breathing without need for any forced manoeuvres.

Effects of nicotine/flavor-free e-cigarette use on lung functions in healthy & asthmatic individuals
Electronic cigarette is available everywhere and is aggressively marketed as a safe way to stop smoking. Reality is that we do not know the consequences of vaping on pulmonary health.

Effect of tralokinumab on eosinophilic airway inflammation in uncontrolled moderate-to-severe asthma
Researchers aimed to evaluate whether tralokinumab would have an effect on airway eosinophilic infiltration, blood and sputum eosinophil concentrations, eosinophil activation, and airway remodelling.

Oscillometry and pulmonary MRI measurements of ventilation heterogeneity in obstructive lung disease
In 100 patients ventilation heterogeneity and respiratory system impedance were correlated and both were independently related to quality of life scores and asthma control.

Sputum Eosinophilia and Magnetic Resonance Imaging (MRI) Ventilation Heterogeneity in Severe Asthma
The manucript investigates the contribution of eosinophilic bronchitis and smooth muscle dysfunction to magnetic resonance imaging (MRI) ventilation heterogeneity in patients with severe asthma.

Nasopharyngeal isolates and their clinical impact on young children with asthma: a pilot study
Researchers investigated the nasopharyngeal colonization in children with asthma to determine the prevalence of pathogens and their contribution to respiratory symptoms and airway resistance.

Reduced lung elastic recoil and fixed airflow obstruction in asthma
Fixed airflow obstruction (FAO) in asthma occurs despite optimal inhaled treatment and no smoking history, and remains a significant problem, particularly with increasing age and duration of asthma.

Home-based Forced Oscillation Technique Day-to-Day Variability in Pediatric Asthma
Presentation of illustrative cases highlighting the potential of home-based FOT daily measurements to better characterize asthma exacerbations and detect changes in asthma control.

IOS vs AOS: Comparative Bias in Respiratory Impedance Measurements
The forced oscillation technique (FOT) measures respiratory impedance during normal tidal breathing. This study compares IOS & AOS devices in patients with asthma & COPD.

Oscillometry and pulmonary magnetic resonance imaging in asthma and COPD
Study of the relationships between parameters measurements in ex-smokers and non-smokers with chronic‐obstructive‐pulmonary‐disease (COPD) or asthma

Interdevice agreement in respiratory resistance values by oscillometry in asthmatic children
Spirometry remains the gold standard for the diagnosis and monitoring of patients with asthma. However, oscillometry, an effort-independent technique, has been shown to be responsive to change.

Measuring the effects of bronchial thermoplasty (BT) using oscillometry (AOS)
Bronchial thermoplasty (BT) is helping patients with severe asthma, but no improvement captured by spirometry. This study evaluates the response to BT using oscillometry.

Bronchodilator Response Assessed by the Forced Oscillation Technique Identifies Poor Asthma Control
The manuscripts presents the comparison of BDR cutoffs by using different methods which are FOT and spirometry.

Airwave oscillometry and patient-reported outcomes in persistent asthma
Airwave oscillometry measurements strongly correlate with IOS and quantify the degree of small airways dysfunction (SAD) [...]

The effect of the extrafine formulation of BDP/FF inhaler on Mexican asthmatic patients
This retrospective analysis reinforces the concept of maintenance treatment focused on inflammation background of the disease and the need of bronchodilator effect also in Mexican population.

Early detection of exacerbation in patients with respiratory diseases including COVID-19
By detecting small airway dysfunction before it becomes symptomatically apparent, Oscillometry might be able to separate COVID-19 patients whose peripheral lungs are affected.

Beyond spirometry
For many decades, requiring patients to make forced, maximal exhalations to measure their expiratory volumes and flows, has been the standard of care for pulmonary function testing (PFT). However, des
