Fig. 5From: Comparison of two devices for respiratory impedance measurement using a forced oscillation technique: basic study using phantom modelsEffects of the respiratory rate on the impedance measured with IOS (a), MG-pulse (b), and MG-noise (c) when the RC model was ventilated with a fixed tidal volume (1.0 l). Plotted data are the mean values of three measurements. Respiratory rate (RR) was set at 0, 10, 20, and 30/minBack to article page
