Relationship between actual stroke volume (aSV) and ventilation efficiency (\( \dot{\mathrm{V}} \)A/a\( \dot{\mathrm{V}} \)E). Markers indicate individual data of aSV and \( \dot{\mathrm{V}} \)A/a\( \dot{\mathrm{V}} \)E. a The results at 6 Hz. b The results at 8 Hz. Dotted lines are exponential approximations. In a (6 Hz), the exponentials (coefficient of correlations (R), P values) are as follows: R100 (IT = 50%), 0.4967 (R = 0.970, P < 0.001); 3100B (IT = 50%), 0.3005 (R = 0.914, P < 0.001; and 3100B (IT = 33%), 0.0948 (R = 0.715, P < 0.001). In the b (8 Hz), the exponentials (R, P values) are as follows: R100 (IT = 50%), 0.5705 (R = 0.986, P < 0.001); 3100B (IT = 50%), 0.3088 (R = 0.886, P < 0.001); and 3100B (IT = 33%), 0.1432 (R = 0.777, P < 0.001)
