Fig. 6.

Comparison of static sequence characterization to compartment model estimation. The previous set of pressure sequences (grey) are represented by static 12-parameter characterization (red) and by breath-to-breath application of the linear compartment model (blue). Estimation of normal breath pressures (A,B,E) is similar in both models. For breaths with marked dyssynchrony (C,D,F), static characterization outperforms the compartment model. Note that the compartment model estimate is dynamic while the red characterization is stationary, and time axes are regularized to a fixed breath cycle length to plot these signals together.
