Abstract
Purpose
Chronic respiratory diseases are prevalent among adults and lung function testing is imperative for appropriate diagnosis and treatment. While spirometry is the standard measure of lung function, there exist groups of individuals unable to adequately perform accurate and reproducible lung function testing. Impedance oscillometry system (IOS) is an effort independent test that may be employed to assess airway function in challenging groups such as children and elderly. This review will compare IOS and spirometry and describe the physiologic measurements of lung function and interpretation strategies in adults with chronic airway disease.
Recent Findings
In adults with COPD, impedance oscillometry measurements of airway resistance correlate with the severity of airflow limitation measured with spirometry. In adults with asthma, IOS is a sensitive measure of airway hyperresponsiveness and bronchodilator response.
Summary
Impedance oscillometry is emerging, alternative method to assess lung function in adults.
