Simulated V̇/Q distribution compared with the data. N is the number of compartments used,${\overline{R}}_{\mathit{Bi}}$ denotes upper bounds of bronchiolar resistance, and${\overline{R}}_{\mathit{Vi}}$ denotes upper bounds of vascular resistances for the i th compartment. (a) N = 50,${\overline{R}}_{\mathit{Bi}}$ = 3 × 10⁵,${\overline{R}}_{\mathit{Vi}}$ = 8 × 10⁶, Error = 5.68. (b) N = 50,${\overline{R}}_{\mathit{Bi}}$= 1.2 × 10⁶,${\overline{R}}_{\mathit{Vi}}$ = 3.2 × 10⁷, Error = 4.25. (c) N = 100,${\overline{R}}_{\mathit{Bi}}$ = 3 × 10⁵,${\overline{R}}_{\mathit{Vi}}$ = 8 × 10⁶, Error = 4.46. (d) N = 100,${\overline{R}}_{\mathit{Bi}}$ = 1.2 × 10⁶,${\overline{R}}_{\mathit{Vi}}$ = 3.2 × 10⁷, Error = 3.24. (e) N = 200,${\overline{R}}_{\mathit{Bi}}$ = 3 × 10⁵,${\overline{R}}_{\mathit{Vi}}$ = 8 × 10⁶, Error = 3.91. (f) N = 200,${\overline{R}}_{\mathit{Bi}}$ = 1.2 × 10⁶,${\overline{R}}_{\mathit{Vi}}$ = 3.2 × 10⁷, Error = 2.80.
