WebTherefore R rs represents the mechanical properties associated with energy dissipation (airway resistance, R aw and tissue resistance, R ti), while X rs is a sum of two opposing energy-storing components: the elastance of the pulmonary and chest wall tissues (E rs; the reciprocal of total respiratory compliance, C rs) and the inertance (I rs) determined … WebJul 22, 2015 · Background: Airway resistance (RAW) and specific airway conductance (sGAW) are measures that reflect the patency of airways. Little is known of the variability of these measures between different lung diseases. This study investigated the contribution of RAW and sGAW to a diagnosis of obstructive airways disease and their role in …

WebSep 12, 2024 · The compliance of a system is defined as the change in volume that occurs per unit change in the pressure of the system. In layman terms, compliance is the ease with which an elastic structure stretches. Compliance is, therefore, basically a measurement of the elastic resistance of a system. Pulmonary compliance (C) is the total compliance of …
WebThe infant whole body plethysmograph is a valuable tool for obtaining simultaneous measurements of lung volume and airways resistance 3. This technique aims to measure functional residual capacity (FRC p or FRC pleth) and airway resistance ( Raw ). From these, other key parameters such as airway conductance ( Gaw =the reciprocal of Raw ...
