From: Generalized estimation of the ventilatory distribution from the multiple-breath nitrogen washout
Sum of squared error (SSE) between estimated and reference ventilation-to-volume distributions. Unimodal (upper panel) and bimodal (lower panel) ventilation-to-volume distributions. All simulation and recovery conditions are depicted and indicated (rows and columns of the matrices). Colors coded on the right side of the figure indicate intervals of values of the mean SSE; EELV end-expiratory lung volume, V T tidal volume
