Reference values of respiratory impedance with impulse oscillometry in healthy Chinese adults [PDF]
Journal of Thoracic Disease, 2020 Abstract Background: Impulse oscillometry (IOS) is a non-invasive pulmonary function test for measuring respiratory impedance. Available reference equations of IOS indices for adults are limited. The aim of this study was to develop reference equations of IOS indices for Chinese adults.Methods: In a multicentral, cross-sessional study of ...

Importance of impulse calibrator output impedance and method of all-waveform compensation
, 2023 The influence of the impulse calibrator output impedance on the measured waveform is often ignored because of the rather limited bandwidth of lightning and switching impulses and the short cable connection to the digitizer.
