Fig. 1From: Explainable machine learning methods and respiratory oscillometry for the diagnosis of respiratory abnormalities in sarcoidosisElectrical representation of a two-compartment extended RIC (eRIC) model to analyze respiratory impedance. Resistance, inductance, and capacitance are mechanical resistance, inertance, and compliance analogs, respectively. R is analogous to central airway resistance, and Rp describes peripheral resistance. I is associated with lung inertance and C with respiratory compliance. This analysis also evaluated the total resistance (Rt = R + Rp), which included the effects of central and peripheral airwaysBack to article page
