Reference Value of Impulse Oscillometry in Taiwanese Preschool Children

Pediatrics and Neonatology, 2015
Impulse oscillometry is a potential technique for assessing the respiratory mechanism—which includes airway resistance and reactance during tidal breathing—in minimally cooperative young children.

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.

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

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.

Day-to-Day Variability of Respiratory Resistance in Asthma and COPD: Influence of Intra-Breath Data Sampling and Observation Period [PDF]

IEEE Journal of Translational Engineering in Health and Medicine
Objective: Assessment of lung function variability is recommended for the diagnosis of asthma, but its specificity in separating asthmatic from COPD subjects is low.

Characterization of chronic lung allograft dysfunction phenotypes using spectral and intrabreath oscillometry

Frontiers in Physiology, 2022
Background: Chronic lung allograft dysfunction (CLAD) is the major cause of death beyond 2 years after lung transplantation and develops in 50% of all patients by 5 years post-transplant.

Role of impulse oscillometry in diagnosis and follow-up in bronchial asthma

Lung India, 2023
Background: Asthma is defined as a chronic inflammatory disorder of the airways, characterized by bronchial hyper-responsiveness and variable airflow obstruction, that is often reversible either spontaneously or with treatment.

Lung disease burden assessment by oscillometry in a systematically disadvantaged urban population experiencing homelessness or at-risk for homelessness in Ottawa, Canada from a prospective observational study

BMC Pulmonary Medicine, 2022
Rationale Oscillometry is an emerging technique that offers some advantages over spirometry as it does not require forced exhalation and may detect early changes in respiratory pathology.

Intra-subject variability in oscillometry correlates with acute rejection and CLAD post-lung transplant

Frontiers in Medicine, 2023
BackgroundChronic lung allograft dysfunction (CLAD) is the major cause of death post-lung transplantation, with acute cellular rejection (ACR) being the biggest contributing risk factor.

Intra-breath oscillometry for assessing respiratory outcomes [PDF]

, 2021
Respiratory oscillometry (also known as the forced oscillation technique) is increasingly contributing to lung function studies in clinical routine and research, as a result of its sophistication, non-invasiveness and minimal interaction with normal ...

Reference values of impulse oscillometric lung function indices in adults of advanced age. [PDF]

, 2013
Impulse oscillometry (IOS) is a non-demanding lung function test. Its diagnostic use may be particularly useful in patients of advanced age with physical or mental limitations unable to perform spirometry.
