Additional file 2: of Comparison of the ventilation characteristics in two adult oscillators: a lung model study

Alveolar ventilation ( V ̇ $$ \dot{\mathrm{V}} $$ A) measured with targeted actual stroke volume (aSV). Bar graph indicates mean V ̇ $$ \dot{\mathrm{V}} $$ A (n = 5), and vertical bar indicates standard deviation. The results of the statistical significance test in Additional file 2a (6 Hz) are as follows: R100 (IT = 50%) vs 3100B (IT = 50%): ns with aSV = 80 and 120, P < 0.001 with aSV = 160; R100 (IT = 50%) vs 3100B (IT = 33%): P < 0.001 with all aSV; 3100B (IT = 50%) vs 3100 B (IT = 33%): P < 0.05 with aSV = 80, P < 0.001 with aSV = 120, P < 0.01 with aSV = 160. The results of the statistical significance test in Additional file 2b (8 Hz) are as follows: R100 (IT = 50%) vs 3100B (IT = 50%): ns with aSV = 80, P < 0.001 with aSV = 100 and 120; R100 (IT = 50%) vs 3100B (IT = 33%): P < 0.001 with all aSV; 3100B (IT = 50%) vs 3100B (IT = 33%): P < 0.001 with all aSV.
