Spirometry Using Electrical Impedance Tomography (EIT)
Realization of Spirometry Measurement Using Electrical Impedance Tomography (EIT)
The main aim of this study is to test spirometry measurements using EIT with a calibration using tidal volume obtained from the simultaneous standard spirometry measurement. Another goal is to compare, based on the calibration, the spirometry parameters obtained from separate measurements using EIT and the standard spirometry using a pneumotachograph.
All spirometry measurements will be conducted in accordance with the latest available standards of the American Thoracic Society (ATS) and European Respiratory Society (ERS) from the year 2005, including their emendation from 2017.
