From: Generalized estimation of the ventilatory distribution from the multiple-breath nitrogen washout
Influence of errors of dead space on the estimated distribution. Boxplot of all estimated unimodal distributions with EELV = 1.0 L, logSD = 0.55, 3 % of noise on N2 concentration and 5 % of error in dead space (\(v_{d}\)) volume estimation. Only the case with alveolar unit weight, fixed Tikhonov gain and consensus washout is represented. Both constrained (blue) and unconstrained (green) linear solvers are shown. Reference distribution (black) and estimated without \(v_{d}\) error (red). Black dots median values, wide bars first and third quartiles, thin lines extend to extreme values that are not outliers, colored circles outliers
