Evaluation of forced oscilometry technique's parameters in severe obstructive sleep apnea patients without breathing disorder

Journal of Family Medicine and Primary Care, 2020
Background: Forced oscillometry technique (FOT) is a noninvasive technique that measures reactance and resistance capacity of the lung and is a practical and less time-consuming technique for respiratory effort assessment.

A comparison of respiratory oscillometry and spirometry in idiopathic pulmonary fibrosis: performance time, symptom burden and test–retest reliability

ERJ Open Research
Study question In large multinational patient surveys, spirometry (which requires repeated, reproducible maximal efforts) can be associated with cough, breathlessness and tiredness, particularly in those with idiopathic pulmonary fibrosis (IPF ...

Effects of Forceful Breathing Maneuvers of Spirometry on Respiratory Impedance Measured by Oscillometry [PDF]

Tuberculosis and Respiratory Diseases
Background Deep inspiratory maneuvers can modify airway diameter, leading to shortterm fluctuations in respiratory impedance (Zrs). However, the impact of the forceful breathing maneuvers used in spirometry on Zrs has not been systematically investigated.

Nasal Airway Transcriptome Reflects Selected Asthma‐Associated Gene Signatures in the Lower Airways

Allergy, Volume 81, Issue 9, Page 3197-3205, September 2026.
Seven genes and two gene modules were consistently associated with asthma in both airway compartments in ARMS and were validated in ATLANTIS. The two modules reflected IL‐13 related inflammation and mast cell activity, respectively. Nasal gene signatures provide a non‐invasive proxy for selected bronchial asthma‐associated gene signatures.

Standard pulmonary function tests and respiratory oscillometry patterns in hypersensitivity pneumonitis and idiopathic pulmonary fibrosis

BMJ Open Respiratory Research
Background Hypersensitivity pneumonitis (HP) is an interstitial lung disease (ILD) caused by repeated exposure to inhaled antigens, leading to small airway and parenchymal inflammation. Diagnosis is based on a detailed clinical history, chest imaging and

Non‐Invasive Assessment of Endothelial Dysfunction and Arterial Stiffness in Fontan Circulation

European Journal of Clinical Investigation, Volume 56, Issue 9, September 2026.
The Fontan procedure is the definitive treatment for complex congenital heart disease, creating a circulation without a subpulmonary ventricle. This altered hemodynamic state negatively affects endothelial function, contributing to progressive organ dysfunction and long‐term morbidity.

Estimation of pulmonary function from time‐resolved dynamic chest radiography using machine learning in patients with respiratory disease

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Pulmonary function tests (PFTs), particularly spirometry, are the reference standard for assessing airflow limitation in respiratory diseases such as chronic obstructive pulmonary disease (COPD) and interstitial pulmonary disease.

Interpreting respiratory oscillometry in adults with asthma or COPD: findings of an international Delphi study

ERJ Open Research
Background Respiratory oscillometry measures the physiological effort and mechanics of moving air in and out of the lungs during normal breathing. It provides complementary information to spirometry.
