There is a big difference in the data. A face is relatively smooth and flat compared to your lung which seems to be heavily aliased with many sharp edges. The sharp edges are limiting what can be decimated, Try either
1) pre-smooth the data (vtkSmoothPolyDataFilter or vtkWindowedSincPolyDataFilter)
2) set the feature angle in the decimator to a high value (>90 degrees)
You can also post-smooth the data with good results.
